All notable changes to CodeGraph are documented here. Each entry also ships as
a [GitHub Release](https://github.com/colbymchenry/codegraph/releases) tagged
`vX.Y.Z`, which is where most people will look.

This project follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/)
and adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### New Features

- Indexing TypeScript, TSX, JavaScript, JSX, Java, Python, and Go projects is faster: parsing and symbol extraction now run in a native engine when a prebuilt binary is available for your platform (release bundles include one), producing exactly the same graph — verified byte-for-byte against the previous engine on real repositories, from small libraries up to vscode-, dubbo-, and django-scale codebases (Lombok-generated members included). The speedup is largest on resource-constrained machines like CI runners. No setup needed: platforms without the native binary, and individual files with syntax errors, automatically use the previous engine, and `CODEGRAPH_KERNEL=0` turns the native path off entirely.
- Reference resolution now runs in parallel on large projects. When a project has enough pending references to make it worthwhile (roughly 150k+, typical for big Java/Kotlin/Spring codebases), resolution fans out across worker threads while results are applied in the exact order the single-threaded path would have used — the graph comes out byte-for-byte identical, about twice as fast end-to-end on a 4,000-file Java project in our testing. Small projects keep the single-threaded path automatically (the fan-out costs more than it saves there). Set `CODEGRAPH_NO_PARALLEL_RESOLVE=1` to disable, or `CODEGRAPH_PARALLEL_RESOLVE_MIN=<count>` to tune when it engages.
- Indexing large projects got another sizeable speedup — about a quarter less wall-clock on the same 4,000-file Java project, with the graph still byte-for-byte identical. Two changes: the database no longer interleaves expensive checkpoint housekeeping into the middle of resolution on a fresh index (it's folded once at the end instead), and while one batch's results are being written out, the worker threads are already resolving the next batch instead of sitting idle.
- The dynamic-dispatch analysis that runs at the end of indexing (callback, event, and framework wiring) now runs its passes in parallel on large projects, cutting that stage roughly in half there — and a pass that crashes now retries safely instead of failing the whole index, which also makes very large codebases that previously died in this stage more likely to index to completion. Graphs remain byte-for-byte identical.
- On large projects, indexing writes its relationship data noticeably faster: secondary database indexes are set aside during the bulk of reference resolution and rebuilt once at the end, instead of being maintained row by row. Graphs remain byte-for-byte identical, and small projects are unaffected.
- Very-large-codebase reliability: on multi-million-symbol projects, an analysis pass that fails on a worker thread is now skipped with a clear message instead of being retried in a way that could take down the whole index, and the end-of-indexing index rebuild no longer risks tripping the liveness watchdog on huge graphs. Validated end-to-end on the Linux kernel (70k files, 2M symbols, 6.4M relationships) — it now indexes to completion even on a 2-core machine.
- Indexing is significantly faster — a fresh `codegraph init` on a medium TypeScript project takes about a third less wall-clock time, with the same graph produced byte-for-byte. The gains come from batching database writes, storing files on a dedicated writer thread, memoizing repeated import-resolution lookups, skipping per-row search-index maintenance during the bulk build (rebuilt once at the end), and — on completely fresh databases only — deferring disk durability until the index completes, since an interrupted first index is simply re-run. Set `CODEGRAPH_NO_FAST_INIT=1` to keep full crash-durability during the initial build, or `CODEGRAPH_NO_STORE_WORKER=1` to store on the main thread.
- `codegraph install` and `codegraph upgrade` now offer CodeGraph Pro beta access after finishing — answer yes, type your email, and you join the same waitlist as the getcodegraph.com homepage form. Strictly opt-in and asked at most once per machine total: nothing is sent unless you say yes and enter an email, either answer is remembered so no later install or upgrade ever re-asks, and non-interactive runs (`--yes`, scripts, CI) never see the question.
- Every release is now cryptographically verifiable: npm packages publish with npm provenance (the "Provenance" badge on npmjs.com, proving each version was built by this repository's release workflow from a specific commit), and the GitHub Release bundles carry signed build attestations you can check with `gh attestation verify <file> -R colbymchenry/codegraph`.
- Indexing inside CPU- or memory-limited containers (Docker, CI runners) now sizes its worker pools from the container's actual allowance instead of the host machine's, and giant codebases no longer balloon temporary database files during indexing (previously tens of GB of transient disk on Linux-kernel-scale projects). Together these prevent out-of-memory and out-of-disk failures on constrained machines; set `CODEGRAPH_RESOLVE_WORKERS` to override the resolution worker count explicitly.

### Fixes

- TypeScript, TSX, and JavaScript files now parse with up-to-date grammars — modern syntax such as `using` declarations and import attributes no longer trips parse errors that could drop surrounding symbols. (The previously bundled grammars dated from 2023.)
- Searching or exploring by field names now finds the code that defines them. A query made of object keys or API field names (`profileInfo isTrialEligible quotaInfo billingMethod`) used to return unrelated results while the defining files never appeared, because three retrieval steps each dropped multi-word camelCase terms: an internal case-comparison bug, a match step that only considered classes (never functions or methods), and exploration seeding that required exact symbol-name matches. All three are fixed — `codegraph_explore` with a bag of field names now surfaces the controllers and services that assemble those fields. (#1196)
- `codegraph.json`'s `includeIgnored` works again for the "folder of repos" layout: when one `.gitignore` rule covers a parent directory (`/repos/`) holding several embedded git repositories, opting in the individual repos (`"includeIgnored": ["repos/a/"]` — the exact spelling `codegraph init`'s own hint suggests) previously matched nothing and indexed zero files, looping the same suggestion back at you. Both spellings now work — name the parent directory to opt in everything under it, or name individual repos to opt in just those — and the hint no longer re-suggests repos that are already configured. (#1295)
- Method calls on literals (`", ".join(...)` in Python, `"x".split(...)` in JavaScript, and the like) no longer produce call edges to unrelated project functions that happen to share the builtin's name — a codebase with a function called `join`, `get`, or `update` could show phantom callers from every string-builtin use. Additionally, a function nested inside another function is now only matched as a call target from inside its container, since it isn't reachable from anywhere else. Blast-radius and affected-test results get cleaner on Python and JavaScript codebases especially. (#1230)
- Go method calls through a struct field (`target.conn.Exec(...)`) no longer bind to unrelated same-named local methods when the field's type is external — `conn *sql.DB` calls were being attributed to a local interface that happened to declare `Exec`, fabricating internal dependencies. Chained field calls now resolve by inferring the field's declared type from the struct definition: in-project types (including unexported ones like chi's `tree *node`) gain correct, validated call edges that never existed before, and external types (standard library, third-party modules) are left unlinked instead of guessed. (#1276)
- TypeScript/JavaScript method calls through an imported singleton (`import { store } from './store'; store.notify()`) now resolve to the class method instead of the exported constant, so `codegraph callers` sees cross-file callers of the method — previously only same-file calls were attributed and a method used everywhere could look unused. The same declaration-based type inference applies across the languages that share it (Python, Java, Kotlin, Go, and more), and a failed inference keeps the old edge rather than guessing. (#1292)
- `codegraph node <symbol> -f <file>` now prints the symbol's source body. Pinning an ambiguous name to a specific file (the whole point of `-f` when many files define the same function) returned only the location and caller trail with no code. (#1284)
- Deleting a whole directory is now picked up by watch mode: the files inside it are removed from the index on the next auto-sync instead of lingering as stale records until an unrelated edit happened to trigger one. Operating systems often report a directory deletion as a single event on the directory itself (with no per-file events for its contents), which the watcher previously discarded. (#1285)
- `codegraph sync` now gets the same slow-disk fix that made full indexing fast in 1.4.0: database checkpointing is deferred for the whole incremental run instead of firing every few megabytes of writes. On mechanical drives and other high-latency storage, a small sync on a large index no longer stalls for minutes at near-zero CPU — the cost of a sync scales with what changed, not with the size of the existing index. The same `CODEGRAPH_NO_WAL_DEFER=1` switch turns it off. (#1248)
- C functions declared with a project-specific attribute macro in front of a typedef'd return type (`SEC_ATTR UINT32 MyFunc(VOID)` — common in embedded and kernel code) are now indexed under their real names. Previously the parser tripped over the unknown macro and stored the parameter list as the function name, leaving entries like `"(VOID)"` in the graph and making the real function unfindable. (#1211)
- C++ methods defined out-of-line inside a namespace (`namespace sim { Output MyClass::Apply(...) { ... } }`) now carry the namespace in their qualified name, matching their class. Fully-qualified call sites from other files (`sim::MyClass::Apply(...)`) resolve to the definition again, so `codegraph callers` and file impact no longer come up empty for this pattern. (#1291)
- C++ methods defined out-of-line on a template class (`template <typename T> T Box<T>::get() { ... }`) no longer keep the template parameter list in their qualified name. They now index as `Box::get` — identical to an inline definition of the same method — so they link to their class and resolve from call sites again, and pathological multi-line template parameter lists can no longer blow the qualified name past filesystem name limits. (#1286)
- Go route detection no longer misidentifies ordinary method calls that share HTTP verb names — `cache.Put("key", value)`, `store.Get("config", out)`, `bus.Handle("user.created", handler)` and the like were being indexed as HTTP routes, polluting route listings in cache-heavy codebases. A registration now has to look like one: its first argument must be a `/`-prefixed path (all routers) or a Go 1.22 `"METHOD /path"` pattern on `Handle`/`HandleFunc`, which now also extracts the method instead of listing the route as `ANY`. (#1259)
- Progress output on Windows no longer mixes ASCII `|` rails with the Unicode `│ ◆ ●` frame around them. In terminals that render Unicode (Windows Terminal, VS Code, ConEmu/Cmder, JetBrains, Alacritty), the whole `codegraph init` / `index` / `sync` block now draws with matching box-drawing characters; unrecognized legacy consoles keep the safe all-ASCII output that avoids garbled characters. `CODEGRAPH_ASCII=1` / `CODEGRAPH_UNICODE=1` still override in either direction. (#398)
- CLI output now honors the `NO_COLOR` convention and new `--color` / `--no-color` flags, and goes plain automatically when piped: commands like `codegraph status`, `query`, `callers`, and `files` no longer embed ANSI color codes when stdout isn't a terminal, and a piped `codegraph init` / `index` / `sync` prints simple per-phase lines instead of progress-animation control characters. `FORCE_COLOR` or `--color` forces color back on for pipes that render it. (#1281)
- Callers and impact analysis no longer silently under-count a function that calls the same callee many times. When one caller contained several call sites to the same callee and an internal resolution batch boundary happened to split them, cleanup after the first batch removed the later sites' pending rows before they were ever attempted — their edges were never created, deterministically, and which edges went missing shifted with unrelated changes to the project's total reference count. Post-pass cleanup now targets the exact database row each processed reference came from. Found while validating the operator-call fix on nlohmann/json, where `write_cbor`'s 11 calls to `to_char_type` indexed as 10. (#1269)
- C++ explicit operator calls — `a.operator+(b)`, `p->operator+(b)`, `a.operator[](3)`, and the other symbolic forms — now produce a `calls` edge to the operator method, so an operator invoked only through the explicit syntax no longer looks uncalled in callers and impact analysis. tree-sitter parses these call sites with the operator name stranded in an error node (never as a normal member access), so the call's target was silently read as just the receiver variable; the operator name is now recovered from the error node and resolved through receiver-type inference like any other member call — a same-named operator on an unrelated class can never capture the edge. Infix uses (`a + b`, `a[i]`) need real type inference and are tracked separately. (#1247)
- `codegraph init` and `codegraph index` no longer look hung after "Resolving refs" reaches 100%. The dynamic-dispatch linking that runs after resolution (callbacks, React re-renders, C function pointers, and the rest) had no progress display, so on repos where it takes a while — large C codebases especially — the bar just sat frozen at 100% until it finished. That work now shows as its own "Linking dynamic dispatch" progress phase, and the heaviest pass — C function-pointer linking — additionally reports progress within the pass, so a large C codebase advances the bar smoothly instead of parking it on one number for the bulk of the phase.
- Indexing no longer prints repeated "SQLite is an experimental feature" warnings that garbled the progress display. The warning comes from Node's built-in SQLite and fired once per parsing worker; it's now suppressed on every launch path.

## [1.4.1] - 2026-07-10

### New Features

- The MCP server now notices when a newer CodeGraph release exists and tells you — a long-running server used to drift behind releases silently until something broke. On startup it checks the latest release in the background (never blocking, at most once a day, cached across all servers on the machine) and surfaces a one-line "update available — run `codegraph upgrade`" notice in the server log, in the instructions your agent sees on connect, and in `codegraph_status`. Nothing updates by itself, and being offline just means no notice. Opt out with `CODEGRAPH_NO_UPDATE_CHECK=1`; `DO_NOT_TRACK=1` disables it too. (#1243)

### Fixes

- `codegraph upgrade` on a Windows npm install actually runs npm again — modern Node refuses to launch `npm.cmd` directly, so the upgrade failed with a spawn error before doing anything. npm is now invoked the way a terminal would run it. (#1238)
- `codegraph uninstall` now actually uninstalls CodeGraph. It used to remove only the agent configurations and leave every installed binary behind, so `codegraph` still ran afterward — especially confusing when both an npm global install and a standalone install were present and removing one still left the other answering on PATH. Uninstall now finds every install on the machine (the standalone bundle, the npm global package, the launcher link) and removes them all, after showing you exactly what it found and asking first (`--yes` skips the prompt). Machine-level settings like your telemetry choice are preserved, a source checkout is never touched, and the new `--keep-cli` flag restores the old configs-only behavior. (#1071)
- `codegraph_explore` no longer lets ordinary English words in a natural-language question hijack the ranking when they happen to match a code symbol's name. A question like "how does the upgrade flow check the latest version" used to treat "check" as a symbol the agent asked for by name, rank that unrelated definition's file first, and crowd the files the question is actually about out of the answer entirely. Precisely written symbol names (camelCase, PascalCase, snake_case, qualified names) still get top billing exactly as before, as do plain-word symbol bags whose words belong together in the same file.
- PHP method calls made through a class property — `$this->dep->method()`, the dominant call shape in constructor-injection codebases (Symfony, Laravel) — now resolve to the method on the property's declared type, so callers and impact analysis see production call sites instead of reporting a DI-heavy method as uncalled or test-only. Promoted constructor parameters, typed properties, classic constructor assignment (including multi-line signatures), and typed setter injection all count; interface-typed properties resolve to the interface method, and inherited methods resolve through the type hierarchy. Only property-shaped declarations are consulted — a same-named local variable or parameter elsewhere can never mistype the property — and a property whose type can't be recovered statically stays unlinked rather than guessed. Thanks @w0lan. (#1220)
- `codegraph upgrade` now also refreshes what previous versions installed into your agents — the CodeGraph section in CLAUDE.md / AGENTS.md / GEMINI.md and the MCP entry — so upgrading no longer leaves agents following instructions written for tools that have since been renamed or removed. Refresh-only: agents you never configured are not touched, and your permission and hook choices are preserved. Also available manually as `codegraph install --refresh`, and skippable with `CODEGRAPH_NO_INSTALL_REFRESH=1`. (#1238)
- `codegraph upgrade` on an npm install now upgrades through npm again instead of quietly creating a second copy that never wins the PATH race — previously `codegraph --version` kept reporting the old version forever, no matter how many times you upgraded. (#1238)
- After every upgrade, CodeGraph now checks that the `codegraph` command your terminal resolves actually serves the freshly installed version — confirming you don't need a new terminal, or telling you exactly which stale install is shadowing the new one. (#1071)
- The safety watchdog no longer kills a healthy index on severely degraded storage. It used to judge liveness purely by the event loop, so one long database write on a struggling disk looked identical to a hung process and could get a valid, in-progress index terminated. During `codegraph index`/`codegraph init` the watchdog now also checks whether the index files on disk are advancing before it acts: slow-but-progressing work is left alone (bounded by a hard cap), while a genuinely hung process is still killed exactly as fast as before. (#1231)
- Incremental sync now picks up cross-file relationships that only become resolvable after an edit — for example, when a file gains an export that another, unchanged file was already importing or calling. Previously the reference in the unchanged file was never revisited, so callers, impact, and flow results silently omitted the new edge (while status reported a clean index) until a full re-index. References that can't be resolved yet are now remembered and automatically retried whenever a change introduces a symbol that could satisfy them — this also covers a class gaining a new method that other files already call. Thanks @loadcosmos for the report with a minimal reproduction. (#1240)
- The reverse case is fixed too: when an edit removes or moves a symbol (or deletes its file), callers in unchanged files now re-resolve during the same sync — rebinding to the symbol's new home when it moved, or waiting to reconnect automatically when it comes back — instead of silently losing their relationship until a full re-index. (#1240)

## [1.4.0] - 2026-07-10

### New Features

- Indexing is dramatically faster on slow storage — mechanical HDDs, network folders, and virtualized disks. The database no longer folds its write journal back into the main file thousands of times during a bulk index (that folding was ~95% of all disk activity); it now streams writes sequentially and folds them back in a few large, coalesced passes that run off the main thread. In a disk-throttled benchmark matching the reported hardware, a mid-size Java project went from over 25 minutes to under a minute, and there is no change on fast disks. Opt out with `CODEGRAPH_NO_WAL_DEFER=1`; tune the fold-back threshold with `CODEGRAPH_WAL_VALVE_MB`. (#1231)
- New `CODEGRAPH_PARSE_TIMEOUT_MS` environment variable to raise the per-file parse budget on unusually slow storage, the same way `CODEGRAPH_PARSE_WORKERS` already tunes the worker count. (#1231)

### Fixes

- Indexing on slow storage (mechanical HDDs, network folders) no longer collapses into false "parse timeout" failures. When disk writes stalled the coordinating thread, parses that had already finished — including empty files — were being misjudged as hung, their workers killed, and the files silently dropped from the index. A parse result is now judged by the worker's own clock, so a stalled coordinator accepts the finished result instead of killing the worker; only a genuinely hung parse is terminated (after a wider grace window). Files that do hit the timeout are retried at the end of indexing instead of being silently lost. Thanks @KnifeOfLife for the exceptional report. (#1231)
- Parse workers now receive their grammar files from memory instead of each re-reading them from disk on spawn, eliminating a feedback loop on slow disks where every worker restart added more disk contention — and making worker restarts cheaper everywhere. (#1231)

## [1.3.1] - 2026-07-09

### Fixes

- Fixed `codegraph init` grinding for 20+ minutes (or getting killed by the safety watchdog) near the end of the "Resolving refs" step on large PHP and JavaScript codebases — a regression since 0.9.x reported on a 12,000-file project that used to index in about a minute. One of the dynamic-dispatch analysis passes only ever applies to Swift/Kotlin closure collections, but it was scanning every function in every language, and on `.push(`-heavy JavaScript (or any codebase with big generated functions, especially with non-ASCII text) its per-match bookkeeping went quadratic. The pass now skips languages it can't apply to, does its line accounting in constant time, and stays responsive even inside a single pathological function — the graph produced is identical. Thanks @sniperrenren for the report. (#1235) Two failure modes are fixed: on multi-million-symbol projects (e.g. the Linux kernel, ~95,000 files) the final analysis phase ran out of memory and crashed the process outright, and on large projects on slower machines (reported on a 24,000-file Java project on Windows) the same phase could stall long enough that the safety watchdog killed a healthy, still-progressing index at ~98% (#1212). The whole phase now streams its work instead of holding whole-graph snapshots in memory, keeps the process responsive throughout, and skips analysis passes for languages a project doesn't contain — which also makes the tail of indexing noticeably faster on single-language repos. The resulting graph is identical, and a genuinely wedged process is still detected and killed.
- Indexing and `codegraph sync` stay responsive through their heaviest internal steps on huge projects: the post-index database maintenance (which on a multi-gigabyte index could stall the process for minutes and get a fully successful index killed by the safety watchdog at the finish line) now runs on a background thread, storing a giant generated file no longer freezes the process mid-extraction, and the reference-resolution bookkeeping between progress updates is broken into small responsive steps. The resulting graph is byte-for-byte identical.
- Fixed a race that could leave a freshly-attached MCP session permanently silent: when a client's first messages arrived glued together during the daemon's connection handshake (roughly one attach in five on a busy machine), the daemon could drop them and stop reading that connection entirely — every tool call from that session then hung with no reply. The handshake now hands the connection over losslessly, and the fix is validated by hammering the previously-flaky attach test 25× under load.
- The first tool call after the shared daemon starts no longer waits behind the query workers' cold start (which can take many seconds on a busy machine) — it's served directly until the first worker is warm, so a fresh session answers immediately.

## [1.3.0] - 2026-07-07

### New Features

- CodeGraph now indexes **Nix** (`.nix`) — flakes, NixOS and home-manager modules, overlays, and package sets join the graph: `let` and attrset bindings, functions (simple, destructured `{ pkgs, ... }`, and curried), and `inherit` bindings all become searchable symbols, with call edges between bindings. File-level wiring follows the ways Nix actually connects files: `import ./relative/path.nix` (with `import ./dir` reaching the directory's `default.nix`), NixOS module `imports = [ ./hardware.nix ../common ]` lists, flake-style `modules = [ ./configuration.nix ]` lists, and the nixpkgs `callPackage ./pkgs/foo { }` idiom — so "what does this configuration actually pull in" and "what uses this module" are answerable on real setups. Dynamic references (`import <nixpkgs>`, variable paths, flake-input module references) are deliberately left unlinked rather than guessed. Thanks @TyceHerrman. (#324, #332, #648)
- The NixOS module system's option wiring is bridged, so flow questions cross the module boundary instead of going dark at it: a config write like `launchd.user.agents.myapp = { ... }` or `home.file.".gitconfig" = { ... }` links to the module that declares that option (`options.launchd.user.agents = mkOption { ... }` — flat and nested declaration spellings both count, quoted keys like `system.defaults.NSGlobalDomain."com.apple.dock"` match their exact declaration), which makes "how does enabling this service produce the launchd daemon / generated config file" traceable end-to-end and "what sets this option" answerable across modules, tests included. Precision is deliberately conservative: interpolated `${...}` paths, options declared in more than one module, and submodule-internal option namespaces stay unlinked rather than guessed, and every bridged hop is labeled as heuristic module-system wiring rather than shown as a plain reference.
- CodeGraph now indexes **ArkTS** (`.ets`) — the language of HarmonyOS / OpenHarmony apps. Everything TypeScript gets extracted (classes, interfaces, enums, type aliases, imports/exports, call edges), plus ArkTS's own constructs: `@Component` / `@ComponentV2` structs with their decorators (`@Entry`, `@State`, `@Prop`, `@Link`, `@Local`, `@Param`, …) captured and searchable, `build()` view trees linked parent→child so "which pages render this component" is answerable, chained attributes connected to the `@Extend`/`@Styles` functions they invoke, `@Builder` methods and functions wired into the call graph, and `.onClick(this.handler)`-style event bindings linked to their handler methods. Modular HarmonyOS projects resolve across module boundaries too: a bare `import { CartRepository } from "data"` follows the `oh-package.json5` `file:` dependency to the right module — honoring each module's declared `main` entry, from `.ets` and `.ts` consumers alike — while ambiguous names in multi-app monorepos deliberately stay unlinked rather than guessed, and mixed `.ets`/`.ts` codebases cross-link freely. Validated on real HarmonyOS apps including the official OpenHarmony samples monorepo. (#396, #512, #648, #890)
- ArkUI's dynamic hops are bridged so flow questions cross them instead of going dark, each labeled as dynamic dispatch rather than shown as a plain call: methods that assign a reactive property (`@State`, `@Local`, …) link to the component's `build()` (the re-render hop — assignment-gated, so a method that merely reads state gets no edge); `emitter.emit(eventId)` links to the matching `emitter.on/once` subscriber when both sides share a statically-recoverable event key (numeric ids pair within one file only, named constants within one module, so unrelated samples in a monorepo never cross-link); and `router.pushUrl({ url: 'pages/Detail' })` links to the target page's `@Entry` struct, with ambiguous urls left unlinked rather than guessed.
- Interrupted or incomplete indexing is now visible instead of silent: a run killed mid-index (crash, out-of-memory, watchdog) leaves a marker that `codegraph status` reports as a truncated index, a completed run that dropped files reports itself as partial — both in the human output and in `status --json` — and `codegraph index` prints a warning with the exact counts when its result doesn't add up to what the scan discovered.
- CodeGraph now indexes **Terraform and OpenTofu** (`.tf`, `.tfvars`, `.tofu`) — resources, data sources, modules, variables, outputs, providers, and every `locals` attribute become symbols (e.g. `aws_s3_bucket.my_bucket`, `var.region`, `module.vpc`, `local.prefix`), and uses like `var.region`, `module.vpc.id`, `data.aws_caller_identity.current`, or `aws_s3_bucket.my.arn` are wired up cross-file, so search, callers, and impact queries return real results on infrastructure repos instead of nothing. Module calls are bridged across the module boundary: a `module` block's inputs link to the child module's variables, `module.vpc.vpc_id` reaches the child's `output "vpc_id"` definition, and the block's local `source` path links to the module's files — so "what breaks if I change this module's variable" reaches every caller instead of dead-ending at the declaration (registry and git sources are deliberately left as visible boundaries rather than guessed). Cross-component wiring through the cloudposse/atmos `remote-state` module connects too: `module.vpc.outputs.vpc_cidr` in one component reaches the `vpc` component's own output when the component name is statically declared (a literal, or a variable with a literal default) and exactly one directory matches — anything dynamic or ambiguous stays unlinked. Aliased providers are first-class: `provider "aws" { alias = "east" }` gets its own symbol, and `provider = aws.east` on a resource (or a module's `providers` map) links to that configuration, found up the module tree the way Terraform actually inherits it. `moved`/`import`/`removed` state-migration blocks and `check` assertions reference the resources they name, so a refactor's paper trail is part of the graph. `.tfvars` assignments link to the variables they set, including var-files kept in a subdirectory. Resolution follows Terraform's real per-directory scoping, so same-named variables across modules never cross-link and "what depends on `var.project_id`" in a multi-module repo never mixes in unrelated modules. Thanks @Javviviii2. (#83, #310, #648)
- CodeGraph now indexes **CUDA** (`.cu`, `.cuh`) — kernels, device/host functions, structs, and classes become symbols, and the host→kernel call edge survives the `<<<grid, block>>>` launch syntax, so questions like "how does this call reach the GPU kernel?" trace across the CPU/GPU boundary instead of going dark at the launch site. Real-world launch styles all connect: templated launches (`my_kernel<Traits, 256><<<grid, block>>>(args)`), launches through a local function pointer (`auto kernel = &my_kernel<...>; ... kernel<<<grid, block>>>(args)` — each branch-assigned target linked), brace-initialized launch configs (`<<<dim3{1,1,1}, dim3{256,1,1}>>>`), and kernels defined through a name-in-first-argument macro (flash-attention's `DEFINE_FLASH_FORWARD_KERNEL(kernel_name, ...) { ... }` style), which now index under their real kernel names. CUDA that lives in plain `.h`/`.hpp` headers — where much real-world device code sits, launch-template headers included — is recognized by content and indexed the same way. Validated on llm.c, flash-attention, and NVIDIA CUTLASS. (#387, #648)
- C++ symbols defined inside `namespace` blocks now carry the namespace in their qualified name (`flash::compute_attn`, C++17 `namespace a::b {` included), and namespace-qualified calls (`ns::fn(...)`) resolve to their definitions — previously such calls never linked at all, which hid much of the call graph in namespace-heavy C++ codebases from callers and impact analysis.
- C++ calls that spell out template arguments (`fn<T, 256>(args)`) now link to the function they instantiate, the same normalization templated base classes already had.
- CodeGraph now indexes **Solidity** (`.sol`) — contracts, libraries, interfaces, structs, enums, modifiers, events, errors, and state variables become first-class symbols, with call edges that follow `emit`, `revert`, modifier guards (`onlyOwner`-style, including base-constructor chains like `constructor() ERC20(...)`), and library/method calls (including `using` directives). `import` directives resolve to the imported file, so cross-contract questions like "trace `transferFrom` through allowance and balance updates" or "how does `onlyRole` reach the role storage?" work out of the box on real Solidity codebases (validated on solmate, solady, and OpenZeppelin Contracts). Thanks @naiba. (#374, #648)
- Erlang behaviour dispatch is now followed through the graph: a framework call through a variable module — cowboy's `Handler:init`/`Middleware:execute` folds, a plugin manager's `Mod:callback(...)` — links to the repo's implementations of the behaviour that declares that callback, so flow traces and impact cross the OTP callback boundary instead of stopping at it. The links are precision-gated: the callback arity must match, exactly one behaviour may own that callback shape (a collision stays unlinked rather than guessed), the implementer must actually export the callback, and the fan-out is bounded — a behaviour with hundreds of implementers stays a visibly dynamic boundary. Every bridged hop is labeled as dynamic dispatch with its wiring site, never shown as a plain static call.
- CodeGraph now indexes **Erlang** (`.erl`, `.hrl`) — functions, with clauses and arities of the same name grouped as one symbol spanning all of them, plus records with their fields, `-type`/`-opaque` aliases, `-define` macros, and `-spec` signatures attached to every function. Cross-module `mod:fn(...)` calls resolve to the target module's function, `fun name/arity` values are captured as references (so callback registrations like `lists:foreach(fun submit/1, ...)` link up), `-include`/`-include_lib` connect to the header files they pull in, `-behaviour` declarations link a callback module to its behaviour (and only ever to a module — a same-named macro or function elsewhere in the repo is never mistaken for one), and `-export` lists (plus `-compile(export_all)`) drive each function's public/private flag. OTP's indirection idioms are followed where the target is static: `spawn`/`apply`/`proc_lib`/`timer`/`rpc` calls that name their target as `(Module, Function, Args)` arguments produce call edges, and `gen_server:call`/`cast` connects to the target module's `handle_call`/`handle_cast` — its own when targeting `?MODULE` (including the `-define(SERVER, ?MODULE)` idiom), and the named module when a registered name follows OTP's name-the-server-after-its-module convention (`gen_server:call(other_mod, ...)`, directly or through a `-define(STORE, other_mod)` macro); a registered name that matches no module stays unlinked. Macros participate in the graph too: a `-define` body's calls belong to the macro, each `?MACRO(...)` use site links into the call chain (and bare `?CONSTANT` reads are tracked as references), so a call path hidden behind a macro — `set_password → ?SQL_UPSERT_T → sql_query_t` — traces end-to-end and "where is this macro used" is answerable. escripts index like any module (the shebang line is understood), and OTP application resource files (`.app.src`, `.app`) join the graph: `{mod, ...}` links an app to its callback module and `{applications, [...]}` connects umbrella sibling apps — resolving only ever to modules, so an OTP app name like `ssl` is never mistaken for a same-named function. Truly dynamic dispatch (`Mod:handle(...)`, message sends, var-module spawns) is deliberately left unlinked rather than guessed. `codegraph_explore` also understands Erlang-native symbol spelling in queries — `mod:fn/3` and `init/2` find the symbols they name. (#635, #648)
- CodeGraph now indexes **Visual Basic .NET** (`.vb`) — classes, Modules, interfaces, structures, enums, properties, events, `MustOverride` abstract members, and `Declare` P/Invoke signatures, with `Inherits`/`Implements` hierarchy edges, call edges (resolved through VB's ambiguous call-vs-index parentheses), and `New`/`As New` instantiation links. Real-world VB styles parse cleanly: WinForms designer files, interpolated and multi-line strings, XML literals (embedded `<%= %>` expressions included), single-line and multi-line LINQ queries, multi-line lambdas, `Handles`/`WithEvents` event wiring, Custom Events, date literals, classic type-character identifiers (`i%`, `name$`), and non-English (Unicode) identifiers. (#648, #639, #170)
- CodeGraph now indexes **COBOL** (`.cbl`, `.cob`, `.cpy`) — programs, sections and paragraphs with `PERFORM`/`GO TO` call edges, `CALL` cross-program calls, `COPY` copybook imports (standalone copybooks included), and DATA DIVISION records with 88-level condition names, in both fixed and free source format. Impact queries work on data items: every `MOVE`/`ADD`/`COMPUTE`/`SUBTRACT` write-site links back to the field it changes, so "what touches this copybook field" answers across programs. CICS flows connect too: `EXEC CICS LINK`/`XCTL` program targets, `EXEC SQL INCLUDE` copybooks, and pseudo-conversational `RETURN TRANSID(...)` hops resolve to the program owning the transaction id. (#590, #648)
- CodeGraph now indexes **CFML** (`.cfc`, `.cfm`, `.cfs`) — both the classic tag-based style (`<cfcomponent>`/`<cffunction>`) and modern bare-script `component { ... }` syntax, including `extends`/`implements`, embedded `<cfscript>` blocks (at any nesting depth, including inside `<cfif>`/`<cfloop>`/`<cftry>`), call edges, and calls embedded in `#hash#` expressions inside `<cfquery>` SQL bodies. Files saved with a UTF-8 byte-order mark and tags with unquoted attribute values — both common in long-lived CFML codebases — are handled too. Thanks @ghedwards. (#1118)
- CFML inheritance written as a component path now links to the right component. `extends="coldbox.system.web.Controller"` names its supertype by dotted path and `extends="../base"` by relative path (the FW/1 style) — both previously produced no inheritance edge at all, which on framework-style CFML apps hid most of the type hierarchy from impact and blast-radius analysis (on ColdBox's own core, over 90% of inheritance was invisible). Resolution is deliberately conservative: the target's directory layout must corroborate the declared path — so a supertype that lives in an out-of-repo library (testbox, mxunit, an installed framework) correctly stays unlinked rather than being guessed at, and an ambiguous path produces no edge rather than a wrong one. (#1152)
- CFML method calls made through a local variable, typed argument, or component property now resolve to the right method — the same receiver-type inference the other object-oriented languages already had. `var svc = new UserService(); svc.save()`, `createObject("component", "path.UserService")`, a typed `<cfargument>` or cfscript parameter, and `variables.`/`this.`-scoped fields — including the pseudoconstructor pattern (`variables.svc = new UserService()` in `init()`) and WireBox-injected properties (`property name="svc" inject="UserService"`) — all now link the call to the declared component's method, with methods inherited from a supertype resolved through the inheritance links above. This makes callers, impact/blast-radius, and `codegraph_explore` flow traces follow CFML service calls instead of dropping them or guessing among same-named methods.
- The Claude Code context hook now recognizes prompts that describe code in plain words — in any language — by checking the prompt's words against the symbol names actually in your project's index. Asking about "the state machine des commandes" finds `OrderStateMachine` with no keyword involved. Confidence decides how much gets injected: structural questions and prompts naming a real symbol still get full context up front; a plain-words match gets a short pointer to the matching symbols so the agent queries them itself; everything else stays silent, exactly as before.
- Anonymous usage telemetry now counts how often the context hook injected context, offered a hint, or stayed silent — fixed counter names only; the prompt's content is never stored or sent. This makes the hook's accuracy measurable instead of guessed. The counters record what actually happened, not what was attempted: a lookup that errors or comes back empty counts as a distinct silent outcome, never as delivered context (#1143, thanks @inth3shadows).
- Metal shader files (`.metal`) are now indexed. Metal Shading Language is close enough to C++ that vertex/fragment/kernel functions, structs, type aliases, and the calls between them all land in the graph — so shader pipelines in Apple-platform projects show up in impact analysis and flow traces instead of being silently skipped. Metal's `[[buffer(0)]]`-style attribute annotations are handled so they can't corrupt what gets extracted. Thanks @FluxKo for the report. (#1121)
- CodeGraph now indexes legacy **iBatis 2** SQL maps (`<sqlMap>`), not just MyBatis 3 `<mapper>` files. `<select>`/`<insert>`/`<update>`/`<delete>`, iBatis's `<statement>`/`<procedure>`, and `<sql>` fragments inside a `<sqlMap>` become searchable statement symbols — for both namespaced maps and the namespace-less `Map.statement` id style — and `<include>` references resolve to the fragment they pull in, so search, callers, and impact queries return results on iBatis codebases that previously produced no statement symbols at all. Thanks @ESPINS for the report and the reproduction. (#1182)
- You can now force gitignored first-party source **into** the index with an `include` list in `codegraph.json`. The case this solves: a project tracked by a second VCS (SVN, Perforce, …) alongside Git, where some real source is committed to that VCS and deliberately listed in `.gitignore` so it never lands in Git — git never lists those files, so CodeGraph never indexed them, and neither `includeIgnored` (which only revives *embedded git repositories* inside a gitignored directory) nor `exclude` (its opposite) could help. Add a root `codegraph.json` with, e.g., `{ "include": ["Tools/", "Local/typescript/"] }` and CodeGraph discovers those files directly off disk — overriding `.gitignore` — and indexes them on the full index, incremental `sync`, and file-watching, on both git and non-git projects. Patterns are gitignore-style and matched against project-root-relative paths (a directory, a recursive `**` glob, or a single file). An explicit `exclude` still wins, and built-in skips like `node_modules`, `dist`, and `.git` are never re-included. This complements the existing `exclude` (its opposite — keep tracked files *out*) and `includeIgnored` (opt *in* to gitignored embedded repos).

### Fixes

- Indexing a large Java or Kotlin **Spring** monorepo is dramatically faster. The reference-resolution phase — the bulk of a first-time `codegraph index` — could run for the better part of an hour on a big multi-module project and now finishes in a few minutes, producing the same graph. The cause: every `receiver.method()` call in the codebase was repeatedly scanning the project's entire set of configuration keys looking for a match — work that only ever applies to Spring `@Value` / `@ConfigurationProperties` bindings, never to ordinary method calls. As part of the same fix, a method call whose name coincides with a configuration key (say a `service.process()` call alongside a `service.process` entry in `application.yml`) is no longer mislinked to that config key — it now resolves to the actual method. Thanks @bayernjava for the report. (#1180)
- `codegraph init` at a parent repository whose `.gitignore` excludes its child repositories no longer silently indexes nothing and reports success. The "super-repo of gitignored child repos" layout — a top-level Git repo that `.gitignore`s each `service-*/` or `packages/*` child so `git status` stays quiet — used to index only the parent's few top-level files and print "Done" with 0 nodes, even though running `codegraph init` inside any child worked fine (CodeGraph respects `.gitignore` by default, so the excluded children were skipped). Now, when an index comes up empty, CodeGraph detects the gitignored child repositories that were skipped, names them, and — in an interactive terminal — offers to index them (writing an `includeIgnored` entry to `codegraph.json` and re-indexing on the spot); non-interactive runs print the exact `codegraph.json` snippet to add. Projects that legitimately keep gitignored reference clones out of a working index are never nagged: the offer only appears when the index would otherwise be empty. Thanks @small-thanks for the report. (#1156)
- The MyBatis mapper reader is sturdier on real-world XML. Single-quoted attribute values (`id='getById'`, legal XML and common in older mappers) are no longer skipped, so those statements make it into the graph. Statements and `<include>`s that were commented out with `<!-- ... -->` no longer produce phantom symbols. And two vendor-split statements — the same `id` with `databaseId="oracle"` / `databaseId="mysql"` — written on a single line no longer silently drop one of the pair. Thanks @ESPINS for the report, the reproductions, and the fixes. (#1182)
- `codegraph init` and `codegraph index` no longer get killed by the safety watchdog at the "Resolving refs" step on large method-name-heavy codebases (big Java/enterprise monorepos were the main victims, especially on slower machines). Resolution used to come up for air only every 500 references, so a dense stretch of expensive ones could starve the watchdog long enough for it to assume the process was stuck and kill a perfectly healthy index. Resolution now checkpoints after every reference, and two of the expensive steps got much cheaper: repeated method lookups on the same type are now cached, and source files are no longer re-split line-by-line for every call being resolved — indexing such repos is several times faster as a result. Generated or minified single-line files are also skipped during receiver-type inference instead of being scanned per call. Thanks @UchihaYong and @wangmeng-95 for the reports. (#1122)
- An index left incomplete by an interrupted run now heals itself on the next sync instead of silently staying wrong forever. If indexing died partway through resolving references (a crash, Ctrl-C, or the watchdog kill fixed above), the affected files still looked indexed but their caller/impact edges were missing — a too-small blast radius clustering by package or module, e.g. a Spring `@Resource`-injected method reporting 3 of its 10 real caller files — and because incremental syncs only re-resolve files that changed, the damage was permanent until a full re-index. Any sync (a watched file change, or a bare `codegraph sync`) now detects the leftover references and finishes resolving them, `codegraph status` warns when an index is in that state instead of passing it off as healthy, and a rare early-stop that could abandon resolution on repos whose first files reference only external libraries is fixed too. Thanks @KnifeOfLife for the report and the package-correlation observation that pinned it down. (#1187)
- The shared background server no longer shuts down out from under a live editor/agent session that simply hasn't queried CodeGraph in a while. A safety timer meant to reap an *abandoned* server — one whose client vanished without the connection ever closing — was reaping **any** server that saw no requests for 30 minutes, including a perfectly live session that just wasn't asking CodeGraph anything; that silently dropped the session (and every other session sharing the same background server) to a slower in-process mode for the rest of its life. On one machine over a day it fired 20 times on live sessions and caught zero real phantoms. The timer now checks whether the connected clients are actually still alive and only reaps when none of them are, so a quiet-but-live session keeps its shared server while a genuinely abandoned one is still cleaned up. (#1200)
- CodeGraph's background server no longer leaves a lingering Node process behind when your editor or agent kills its launcher during startup. If the app that started CodeGraph (Codex, Claude Code, or another MCP client) was killed within the server's first fraction of a second — a config probe, a cancelled request, a startup timeout — while keeping the connection's pipes open, the server could be handed off to the system before its orphan-detection watchdog had captured a reference point, leaving it running (idle, ~30 MB) until the launching app itself exited; over a long day of repeated launches these accumulated. The server now records its parent at the earliest possible moment, and the npm and standalone launchers pass the real host's process id down to it so it can watch the host directly instead of only the launcher that may already be gone. As a final backstop, a server that never receives a single request after starting now shuts itself down instead of waiting for the host to exit — tunable with `CODEGRAPH_STARTUP_HANDSHAKE_TIMEOUT_MS` (0 disables). Thanks @ruslan33321 for the report. (#1185)
- The automatic context hook for Claude Code now fires for structural questions asked in nearly thirty languages — French, Spanish, Portuguese, German, Italian, Dutch, Polish, Czech, Romanian, Hungarian, Greek, Swedish, Danish, Norwegian, Finnish, Russian, Ukrainian, Turkish, Indonesian, Vietnamese, Thai, Hindi, Arabic, Farsi, Hebrew, Japanese, Korean, and both simplified and traditional Chinese — instead of just English and simplified Chinese. Previously a natural question like "comment marche la state machine des commandes ?" injected nothing unless it happened to contain a code-shaped symbol name, making the hook look broken for non-English teams. English questions phrased with derived word forms ("explain the architecture…", "what are the dependencies…") now fire too, and prompts in any other language still fire when they name a symbol from the index. Thanks @anthonyle-roy-lgtm for the report. (#1126)
- Lua and Luau method calls with capitalized names (`obj:Method()` — the standard Roblox convention) now link to the right method. Because Lua's method-call syntax looks identical to a Luau type annotation, a capitalized call like `lg:Log()` was misread as declaring the variable's type, so whenever two or more classes shared a method name (`Init`, `Update`, `Destroy`, …) the call was silently dropped from callers, impact/blast-radius, and flow traces. Lowercase method names were unaffected. Thanks @inth3shadows for the precise root-cause analysis and repro. (#1124)
- Removed dead code left behind by the discontinued managed-reasoning feature. Its `codegraph login` flow was unplugged before ever shipping in a release, but the unused module still shipped inside the platform bundles, and a security review flagged its Windows browser-open step (it routed the login URL through `cmd`, which would have been unsafe had the flow ever been wired back up). The leftover module and its tests are now fully deleted. Thanks @inth3shadows for the report. (#1114)
- The Claude Code context hook no longer treats ordinary English words that merely start with "call", "trace", "affect", or "connect" — callus, calligraphy, Connecticut, connective, affectionate, Tracey — as structural questions, which used to inject full CodeGraph context into prompts that had nothing to do with code structure. Genuinely structural forms (calls, callers, callbacks, call site, traced, tracing, affected, connections, connectivity, …) still fire exactly as before. Thanks @inth3shadows for the report. (#1138)
- A stuck git command can no longer hang CodeGraph indefinitely. The git checks behind worktree detection and git-hook setup, and the installer's optional `npm install -g` step, now time out and fail gracefully instead of blocking forever — this matters most for the background MCP server, where an unbounded git hang (network filesystems, a wedged fsmonitor) could previously freeze it long enough for the safety watchdog to kill it. Thanks @inth3shadows for the report. (#1139)
- The context hook's new plain-words matching works immediately on projects indexed by an older CodeGraph version. The word lookup it relies on is built at index time, so a project indexed before the upgrade had an empty one, and the hook would silently find nothing until something else happened to refresh the index; the hook now fills it in on first use (a one-time step — normally the background MCP server's startup catch-up gets there first). Thanks @inth3shadows for the report. (#1142)
- Several accuracy fixes to the plain-words matching: a renamed symbol (for example a NestJS route after its module prefix is applied) stays findable under its new name (#1141); a word that only appears in your code as an import statement's package name is no longer presented as a matched symbol (#1144); plural words no longer generate garbled lookup keys ("services" no longer also looks up "servic") (#1145); and a name matching both the singular and plural of one word can no longer squeeze out a genuine two-word match (#1146). Thanks @inth3shadows for the reports.
- Heavily-reflected Unreal Engine C++ classes are no longer dropped from the index. Reflection markup that decorates members — `UPROPERTY(...)`, `UFUNCTION(...)`, `UCLASS(...)`, `GENERATED_BODY()`, `UE_DEPRECATED_*(...)`, `DECLARE_DELEGATE_*(...)` — are no-semicolon macro calls that tree-sitter doesn't recognize, so each drops into error recovery; in a big class the errors pile up until the whole `class_specifier` collapses and the class, its base clause, and its members vanish (`UCharacterMovementComponent`, with ~240 such macros, disappeared entirely, breaking every subclass/type-hierarchy and blast-radius query that went through it). These line-leading annotation macros are now blanked (offset-preserving) before parsing so the class survives. Thanks @luoyxy for the report and root-cause analysis. (#1093 follow-up)
- Unreal Engine members and methods prefixed by an export/visibility macro are no longer lost. The `*_API` macro doesn't only sit on the class header — it prefixes almost every exported member of a large UE class (`ENGINE_API virtual void Tick(...)`, `static ENGINE_API void AddReferencedObjects(...)`); the parser read the macro as an extra type token and each such declaration fell into error recovery, so on headers like `Actor.h` and `World.h` hundreds of return types piled up as orphan errors and could still tip the class into collapse. Member/method-level `*_API` / `*_EXPORT` / `*_ABI` macros (Unreal, Qt/Boost, LLVM) are now blanked before parsing, mirroring the existing class-header recovery. (#1093 follow-up)
- Unreal Engine annotation macros that appear mid-line — an enum value's `UMETA(DisplayName=...)`, a parameter's `UPARAM(ref)`, or a deprecation tag wedged into a `using` alias (`using FOnNetTick UE_DEPRECATED(5.5, "...") = ...;`, which alone collapsed `UWorld` in `World.h`) — are now stripped too. These sit in positions the line-leading recovery structurally can't reach, and a single one could take down the surrounding enum or class. They are matched by an Unreal-only name list (`UMETA`, `UPARAM`, `UE_DEPRECATED*`) so no standard-C++ or other-library code is affected. Together these three fixes recover the main class of every large Unreal Engine header tested (`Actor`, `ActorComponent`, `SkeletalMeshComponent`, `World`, `LightComponent`, `CharacterMovementComponent`). (#1093 follow-up)
- A C++ header whose only C++ signal is an export-macro-annotated class is no longer misdetected as C — which had silently dropped the class. A `.h` file defaults to C and is only reclassified as C++ when it shows a C++-specific construct, but that check couldn't see through an export/visibility macro: `class ENGINE_API UFoo : public UObject` didn't match the macro-blind `class Name :` pattern, so a lean Unreal-Engine-style header carrying just `GENERATED_BODY()` and no explicit `public:` / `virtual` / `namespace` / `template` was parsed as C. The C extractor emits no class nodes, so the class — and its inheritance link — vanished from the graph, quietly undoing the macro-class recovery added in #1061. The C++ detection heuristic now recognizes an export-macro-annotated `class`/`struct` declaration (the same shape #1061 blanks before parsing), matching how `class Foo : Bar` was already detected; the two-token `<keyword> <MACRO> <Name>` before a `[:{]` never occurs in valid C, so genuine C headers are unaffected. Thanks @luoyxy for the report and root-cause analysis. (#1133)

## [1.2.0] - 2026-07-02

### New Features

- Method calls made through a local variable now resolve to the method in many more languages. When code does `const logger = new Logger(); logger.log();` (or the equivalent), CodeGraph infers the local variable's type from its declaration or initializer and links the call to the right method — so these calls now show up in callers, impact/blast-radius, and `codegraph_explore` flow traces instead of being dropped. Previously only C++ handled this; it now also covers TypeScript, JavaScript, Python, Java, C#, Kotlin, Swift, Go, Rust, Dart, Scala, and PHP. (#1108)
- Ruby method calls made on a receiver (`logger.log`) now record an edge to the method. Previously the Ruby indexer kept only the receiver and discarded the method name, so a method called through a variable or object had no recorded callers and was missing from impact/blast-radius and flow traces; combined with the local-variable type inference above, `logger = Logger.new; logger.log` now links to `Logger#log`. Calls to a class method (`Foo.bar`) and object construction (`Foo.new`) are still recorded too. (#1110)
- The same local-variable method-call resolution now extends to Lua, Luau, R, and Pascal/Delphi. A method invoked through a local — Lua/Luau `local lg = Logger.new(); lg:log()`, R `lg <- Logger$new(); lg$log()`, or Pascal `var lg: TLogger; ... lg.Log` — now links to the right method instead of being dropped. (#1112)

### Fixes

- Indexing a large project no longer gets killed partway through with a "Main thread unresponsive — killing the wedged process" message. The safety watchdog that stops a genuinely stuck index was mistaking slow-but-normal work for a hang: on a big repo, linking up references and cross-file relationships can legitimately run for a while, and that work now regularly yields so the watchdog can tell real progress from a true stall. Projects that previously failed to finish `codegraph init` / `codegraph index` (and had to fall back to `CODEGRAPH_NO_WATCHDOG=1`) now complete normally, while a genuinely hung process is still caught. Thanks @zmcrazy, @YoungLiao, and @GeeLab-Mob for the reports. (#1091)
- On Windows, a console window no longer briefly flashes when CodeGraph runs as a background MCP server. When the npm launcher started the bundled runtime — which happens every time an editor starts the server or reconnects after the daemon idles out — and during its self-heal step that extracts a missing platform bundle, Windows would pop up a black console (conhost) window for a moment. Both now launch hidden, matching how the daemon already behaved; the browser-open step of `codegraph login` was hardened the same way. Thanks @luoyerr for the report and root-cause analysis. (#1092)
- C++ forward declarations no longer crowd out the real class definition. A `class Foo;` forward declaration — common in large C++ and Unreal Engine codebases, where a heavily used class is forward-declared across dozens of headers — was indexed as its own class node every time it appeared. So exploring that class returned mostly forward-declaration sites, and could even pick one of them as the representative for blast-radius, burying the actual definition and its members and callers. Bodiless forward declarations are now skipped for C and C++, exactly as forward-declared structs and enums already were, so only the real definition is indexed. Languages where a class with no body is a complete definition — such as Kotlin's `class Empty` and Scala — are unaffected. Thanks @luoyxy for the report and root-cause analysis. (#1093)
- C++ methods that return a reference, and user-defined conversion operators, are now indexed under their correct names. An inline getter like `const FGameplayTagContainer& GetActiveTags() const` — everywhere in Unreal Engine headers — was indexed as `& GetActiveTags() const` instead of `GetActiveTags`, and a conversion operator like `operator EALSMovementState() const` kept its trailing `() const` instead of reading `operator EALSMovementState`. In both cases the garbled name meant you couldn't find the symbol by name and its callers weren't linked. Both now read cleanly, matching how pointer-returning and value-returning methods already worked. (#1096)
- C++ functions written with an inline-specifier macro before the return type are now indexed correctly. In Unreal Engine, inline helpers are commonly written `FORCEINLINE FString GetEnumerationToString(...)`; the `FORCEINLINE` macro made the parser read the return type as part of the function's name (`FString GetEnumerationToString` instead of `GetEnumerationToString`) and lose the real return type, so the function couldn't be found by name and its callers weren't linked. CodeGraph now recognizes the standard Unreal inline macros (`FORCEINLINE`, `FORCENOINLINE`, `FORCEINLINE_DEBUGGABLE`), so both the name and the return type are captured. (#1100)
- The same function-name recovery now covers inline macros from common third-party C++ libraries, not just Unreal Engine — including pugixml (`PUGI__FN`, `PUGIXML_FUNCTION`), Godot (`_FORCE_INLINE_`), Boost (`BOOST_FORCEINLINE`), and generic `ALWAYS_INLINE` / `FORCE_INLINE`. Functions decorated with these are now indexed under their real names. On a large Unreal project vendoring these libraries this cleaned up the large majority of remaining function-name garbling. (#1101)
- C++ function names are now recovered even when decorated with a macro CodeGraph doesn't specifically know about. A function written `SOME_LIBRARY_MACRO ReturnType doWork(...)` previously had the macro or return type absorbed into its name whenever the macro wasn't one CodeGraph recognized; now the real name (`doWork`) is recovered regardless of the macro, so it's findable and its callers link — no per-library configuration needed. The recognized-macro list was also broadened (Qt, Folly, Abseil, LLVM, V8, Eigen, rapidjson) so those additionally capture the return type. This only ever cleans up an already-garbled name and is limited to C and C++, so ordinary names — and languages like Kotlin and Scala where identifiers can legitimately contain spaces — are unaffected. (#1102)
- The set of C++ libraries whose macros are recognized for full return-type recovery was expanded well beyond Unreal Engine — now spanning Mozilla, Protobuf, {fmt}, nlohmann/json, GLM, Bullet, Skia, OpenCV, EASTL, Cocos2d-x, GLib, SQLite, and the common Windows calling conventions (so `HRESULT WINAPI CreateThing(...)` indexes as `CreateThing` returning `HRESULT`). Functions from libraries not on the list still get their name recovered automatically; being listed additionally recovers the return type. (#1103)
- Graph traversal and blast-radius results no longer drop or miscount relationships in a handful of edge cases. When a symbol could be reached by more than one path, an impact/blast-radius query could leave out a direct dependency between two symbols that were already linked another way; separately, the lower-level graph traversal used by the library API could keep only one of several relationships between the same pair of symbols (for example a symbol that both calls and references another), count a caller reached through two different call sites twice, or return slightly more results than the requested size limit on a very highly-connected symbol. These were long-standing and mostly masked by later de-duplication, so day-to-day query results were largely unaffected, but the traversal now returns the complete, correctly-bounded set. Thanks @inth3shadows for the precise, individually-traced reports. (#1086, #1087, #1088, #1089, #1090)
- Method calls to same-named classes in different files now resolve to the right definition. If two files each declared, say, a `Logger` class with its own `log()` method, a call could be linked to whichever definition happened to be indexed first — so a call in one file wrongly pointed at the class in another, mixing up that method's callers and blast radius. This affected calls written as `obj.log()`, `Logger.log()`, and `Logger::log()` across many languages, including C++, Python, TypeScript, Java, C#, and Rust. When a method name is ambiguous, CodeGraph now prefers the definition in the calling file itself — the correct target in the common case — while Java/Kotlin calls that an `import` already pins to another file are unaffected. Thanks @inth3shadows for the minimal repro and root-cause analysis. (#1079)
- Live auto-sync now gives up cleanly if indexing keeps failing, instead of retrying forever in the background. If a repeatable indexing error kept every sync from completing — for example a file that reliably crashes one language's parser, a full disk, or a corrupt database — a long-running server or daemon would retry every couple of seconds indefinitely, quietly wasting work and filling the logs while the graph silently stopped updating. Auto-sync now backs off after repeated failures and, if they persist, disables itself with an actionable message (naming the underlying error and pointing you to run `codegraph sync`), so the stalled index is surfaced rather than hidden — matching how prolonged file-lock contention and watch-limit exhaustion already degrade. A single successful sync resets everything, so an occasional transient hiccup is unaffected. Thanks @inth3shadows for the precise, code-traced report. (#1127)
- Method calls made through a typed function parameter now resolve to the right method in more languages. A call like `function use(lg: Logger) { lg.log(); }` wasn't linking to `Logger`'s `log()` — CodeGraph inferred a receiver's type from a local declaration but not from a bare typed parameter, so when another class defined a method of the same name the call was dropped from callers and impact/blast-radius. Typed parameters (and method receivers) are now recognized in TypeScript, JavaScript, Rust, Go, Dart, and PHP — including TypeScript generic types (`repo: Repository<User>`) — matching how Java, C#, Kotlin, Swift, Scala, Python, and Pascal already handled it, so the parameter case is now covered across every language that has typed parameters. Thanks @inth3shadows for the isolated repro and root-cause analysis. (#1125)

## [1.1.6] - 2026-06-30

### Fixes

- The standalone installer (`install.sh`) no longer leaves old versions piling up on disk. Each upgrade installed the new release into its own directory and re-pointed the launcher at it, but never removed the previous ones — so on macOS and Linux a full vendored Node runtime (tens of MB per version) accumulated with every update. The installer now keeps only the version it just installed and removes the older ones automatically (the npm installer's download-fallback cache prunes the same way). Windows installs already replaced a single directory in place, so they were never affected. Anything still left behind under `~/.codegraph/versions` from earlier upgrades is safe to delete. Thanks @lalanbv for the report. (#1074)
- `codegraph index` can now rebuild an existing oversized index from an older version, instead of hanging until the watchdog kills it. The previous fix (#1065) stopped *new* indexes from sweeping in a gitignored corpus of nested repos, but a project that had already built the multi-gigabyte graph before upgrading couldn't recover: `codegraph index` is meant to rebuild from scratch, yet it cleared the old graph by deleting every row one at a time, and on a graph of well over a million symbols that took longer than the 60-second responsiveness watchdog allows — so the command was killed before indexing even started, leaving the bad index in place. A full re-index now discards the old database outright and starts fresh, which is near-instant regardless of the old size and also frees the disk the bloated database was holding. Thanks @AriaShishegaran for the detailed follow-up report. (#1067)

## [1.1.5] - 2026-06-30

### Fixes

- C++ classes annotated with an export or visibility macro are now indexed as real classes. This is the `class MYMODULE_API UMyComponent : public UActorComponent` style used throughout Unreal Engine — where an `XXX_API` macro sits between `class`/`struct` and the type name — as well as the equivalent `*_EXPORT` / `*_ABI` macros common in Qt, Boost, LLVM, and many other libraries. Previously that macro made the parser misread the whole declaration as a function, so the class was dropped entirely: it never appeared in the graph and its base class went unrecorded, which made "find subclasses", type-hierarchy, and impact-through-inheritance queries come back empty for effectively every gameplay class in an Unreal Engine project. The class, its members, and its inheritance link are now all captured. Thanks @luoyxy for the detailed report and proposed fix. (#1061)
- `codegraph_explore` now surfaces the options/config type behind a function when you ask, in plain language, what to change to add a parameter to it. A question like "what do I need to change to add a new parameter to X" shares no words with the file that actually defines X's options — for example a functional-options struct and its `With…` builders living in a separate `options.go`, reachable only through X's signature — so that file scored near-zero on every text and connectivity signal and got dropped: explore returned X itself but not the file you'd edit, and the agent fell back to grep. Explore now follows a named function's parameter and return types and pulls in the file that defines them when ranking would otherwise bury it, so the options/config file shows up with its fields. Well-connected types that already rank are left untouched, so ordinary "how does X work" flow questions are unchanged. (The separate tools `codegraph_search`/`codegraph_impact`/`codegraph_node` remain available via `CODEGRAPH_MCP_TOOLS` for anyone who prefers driving each step explicitly.) Thanks @wauxhall for the detailed investigation. (#1064)
- The standalone installers (`install.sh` / `install.ps1`) now warn when a different `codegraph` earlier on your PATH will run instead of the one they just installed. The usual cause is a leftover `npm i -g @colbymchenry/codegraph` from an earlier version, whose launcher keeps running its own pinned version — so the installer reports installing the latest while `codegraph --version` keeps printing the old one, with no hint as to why. The installer now points at the shadowing copy and tells you how to resolve it (remove the other install, or put the new one first on PATH). Thanks @SpringYear for the report. (#1071)

## [1.1.4] - 2026-06-29

### Fixes

- CodeGraph again respects `.gitignore` for nested repositories that git tracks as gitlinks. The recent change that taught CodeGraph to descend into nested repos recorded as `160000` "commit" pointers (#1031, #1033) did so even when your `.gitignore` excludes the directory those repos live in — so a gitignored reference or benchmark corpus full of cloned repositories got pulled into the index anyway. One project with a gitignored `benchmark/repos/` of 19 cloned repos saw over 138,000 files swept in and a 4.8 GiB graph, and a full index then stalled in the "Resolving refs" phase until the watchdog killed it. CodeGraph now treats a gitignored gitlink the same as any other gitignored embedded repo: excluded by default, and re-included only when you opt the directory in with `codegraph.json` `includeIgnored`. Nested repos in non-ignored locations — the case #1031/#1033 fixed — are unchanged. Thanks @AriaShishegaran for the detailed report. (#1065)

## [1.1.3] - 2026-06-29

### Fixes

- CodeGraph now indexes nested repositories that git records as gitlinks, so a workspace built by stacking several repos inside one another indexes completely from a single `codegraph init` at the top. When a repo contains another git repo that was `git add`ed into it — so git tracks it as a `160000` "commit" pointer rather than a folder of files — or a submodule that isn't an active, initialized submodule in your checkout, that nested repo's source used to be skipped entirely: indexing the top level stopped at the nested repo's boundary and pulled in only the outer repo's own files, so a stacked-repo project came up nearly empty (one report saw ~10 files indexed at the root). CodeGraph now descends into each such nested repo that has a real working tree on disk and indexes it as its own embedded repository, recursively, so every layer of a stacked workspace is covered. Active submodules (already handled) and plain untracked nested clones are unchanged; a nested repo under a dependency directory such as `vendor/` or `node_modules/` stays excluded; and a submodule with nothing checked out on disk is correctly left alone rather than reported as empty. Thanks @ofergr and @kun-yx for the reports. (#1031, #1033)
- CodeGraph no longer shows a misleading "different git working tree" warning when you work inside a submodule (or other nested repo) of a workspace you indexed at its root. Because indexing a workspace now pulls in its submodules and embedded clones, a query run from inside one correctly resolves up to the workspace's single index — but it was still warning that the results came from "a different working tree" and suggesting you run `codegraph init -i`, which would have split the submodule back out into its own separate index and undone the unified view. CodeGraph now recognizes that the nested repo's code is already part of the workspace index and stays quiet. The warning still appears for a genuine git worktree — a second checkout of the *same* repository on another branch, which really does have its own uncommitted symbols — since that's the case it exists for. (#1031, #1033)
- On Windows, CodeGraph's background server now shuts down cleanly instead of occasionally aborting with a crash error. When the indexed project contained a nested repository (a submodule or embedded clone), stopping the server could race the file watcher's teardown and exit with a Windows crash code rather than a clean exit. Shutdown now lets that teardown finish first, so the server stops cleanly and promptly. (Windows only; other platforms were unaffected.) (#1033)
- C++ classes that inherit from a templated base — `class Widget : public Base<int>`, a CRTP base like `class App : public CRTPBase<App>`, or a struct inheriting a template — are now linked to that base class in the graph. Previously the template arguments (`<int>`) made the inheritance go unrecognized, so these classes looked like they inherited from nothing and impact/callers analysis stopped at the boundary; the connection is now followed like any other base class. Thanks @ryancu7 for the report. (#1043)
- C++ objects constructed on the stack — `Calculator calc(0)` or `Widget w{1, 2}` — now record that the enclosing function instantiates that class, the same as heap construction (`new Calculator(0)`) already did. Previously only the `new` form was tracked, so a function that built objects with the ordinary stack syntax looked like it didn't construct them and the dependency was missing from impact/callers. Thanks @Dshuishui for the report. (#1035)
- The graph no longer stores duplicate copies of the same relationship. The same dependency between the same two symbols at the same spot could be recorded more than once, which inflated edge counts and let callers/impact results list a relationship twice. Each relationship is now stored exactly once, and existing projects are de-duplicated automatically the next time CodeGraph opens them. Thanks @inth3shadows for the detailed report. (#1034)
- `codegraph node` can now read a file from the command line. File-read mode — pass `-f`/`--file` to get a file's source with line numbers plus the files that depend on it, the same output as the `codegraph_node` MCP tool — was rejected with "missing required argument 'name'", because the command always demanded a symbol name even though file mode has none, leaving the feature unreachable from the CLI. The symbol name is now optional: `codegraph node -f src/auth.ts` (or `codegraph node src/auth.ts`) reads the file, `codegraph node parseToken` looks up a symbol, and running it with neither prints a short usage hint instead of a cryptic error. Thanks @jcrabapple for the report. (#1044)
- `codegraph query` no longer prints meaningless relevance percentages like "12042%" next to each result. The number was a raw full-text search score — useful only for ordering the results, not as a real 0–100% figure — so multiplying it by 100 produced wild values that made the output look broken. Results are already listed best-match first, so the CLI now just shows them in that order with no score, matching what the search tool reports to AI agents. If you script against `codegraph query --json`, the raw `score` is still included for sorting or thresholding. Thanks @jcrabapple for the report. (#1045)
- `codegraph explore` no longer reports an alarming, inflated result count on broad natural-language queries. The "Found N symbols across M files" summary used to count every symbol the search swept in while ranking, so a broad query (for example "publish status to the API") on a large project could announce hundreds of symbols across a big fraction of the codebase — reading as if you had to wade through all of them — even though only the most relevant handful are actually shown with their source. The summary now counts just the files explore returns source for, so the number matches what you see. Ranking and results are unchanged: the right symbols still come first, and any further relevant files are still listed by name under "Not shown above" so nothing is hidden. Thanks @jcrabapple for the report. (#1046)
- Android resource files no longer bloat the index. A `res/` tree — layouts, drawables, value bags (strings, colors, styles), menus, navigation graphs — contains no code symbols, but on an Android app it can be the overwhelming majority of files (one project: 26,000+ XML files, ~97% of everything, contributing zero symbols), which inflated the database, slowed indexing, and padded file counts and `codegraph explore`/search results with entries that have nothing to find. CodeGraph now skips Android resource directories by default — `res/layout/`, `res/values/`, `res/drawable/`, `res/menu/`, and the rest, including their locale/density/version variants like `res/values-es/` or `res/drawable-hdpi/`. Your actual code is untouched, and so is the one kind of XML that does carry symbols — MyBatis mapper files, which live under `src/main/resources/`, not `res/`. `res/raw/` is deliberately kept (it can hold real assets), and you can re-include any excluded directory with a `.gitignore` negation such as `!res/values/`. Thanks @jcrabapple for the report. (#1047)

## [1.1.2] - 2026-06-28

### New Features

- You can now exclude committed directories from the index with an `exclude` list in `codegraph.json` — even when they're git-tracked. `.gitignore` can't drop a directory git already tracks, so a vendored theme or SDK that's checked into your repo (a committed Metronic theme under `static/`, a bundled vendor library) had no supported way to be kept out — it just bloated the graph and slowed indexing. Add a root `codegraph.json` with, e.g., `{ "exclude": ["static/", "**/vendor/**"] }` and those paths are skipped on indexing, sync, and file-watching, on both git and non-git projects. Patterns are gitignore-style and matched against repo-root-relative paths. This complements the existing `includeIgnored` (its opposite — opt *in* to gitignored embedded repos). (#999)
- CodeGraph now follows C/C++ commands that are dispatched through macro-built function-pointer tables, so the handler functions they reach are no longer dead-ends in the graph. Many C projects register a handler into a struct's function-pointer field through a macro and a generated table — redis is the classic case: every command (`getCommand`, `decrbyCommand`, …) is wired into the command struct's `proc` field by a `MAKE_CMD(…)` table that lives in a generated, `#include`-d file, then invoked as `c->cmd->proc(c)`. CodeGraph now reads those macro-built tables — including ones whose struct type is itself a macro alias, whose table sits in an `#include`-d file that is never indexed on its own, or that are wrapped in conditional compilation (`#ifdef`) and defined inline with the struct. It recognizes function-pointer fields declared through a function typedef, and follows the receiver — a chained access (`c->cmd->proc`) or an array subscript through a file-scope table (`(cmdnames[i].cmd_func)(…)`) — across field types. It also follows dispatch through a bare array of function pointers with no struct wrapper at all — the opcode/handler-table pattern common in interpreters and emulators, where a table like `opcodes[op](…)` invokes one of many registered handler functions by index — linking the dispatcher to every handler in the array. The upshot: asking for the callers or blast radius of a command handler now finds the dispatcher that reaches it. For redis, `call` shows up as a caller of every command; for SQLite, the builtin SQL functions registered through `FUNCTION(...)` link to where they're invoked; for Vim, every `:ex` and normal-mode command links from the dispatcher. (#991, extending #932)
- CodeGraph no longer times out when many agents query it at once. The shared background server that serves all your editor and agent sessions used to run every query on a single thread, so a burst of concurrent requests — for example a swarm of subagents exploring a large monorepo together — queued up behind one another and, while the heavy ones ran, froze the connection so finished answers couldn't even be sent back until the whole batch drained. Past a handful of simultaneous callers that routinely surfaced as MCP request timeouts. The shared server now answers queries across a pool of worker threads, so concurrent requests run in parallel and the connection stays responsive the whole time; when it's genuinely saturated a call returns a brief "busy, retry shortly" note (not an error) instead of hanging past your client's timeout. The pool sizes itself to your machine — roughly one worker per core, leaving one for coordination — and a single editor session is unaffected (no pool, no overhead). Set `CODEGRAPH_QUERY_POOL_SIZE` to choose a specific number of workers, or `0` to revert to single-threaded in-process queries.
- Indexing now parses files across multiple CPU cores instead of one, so building a project's graph — `codegraph index`, the first index of a project, and the background re-index after changes — is faster on multi-core machines, most noticeably on large or parse-heavy codebases. The graph it produces is identical to before and re-indexing stays deterministic: parsing runs in parallel, but results are still committed in a fixed order, so the same project always yields the same graph. CodeGraph sizes the pool to your machine automatically (leaving a core free for everything else); set `CODEGRAPH_PARSE_WORKERS` to choose a specific number of parse workers, or `CODEGRAPH_PARSE_WORKERS=1` to restore the previous single-core behavior. Peak memory is unchanged — workers reclaim parser memory independently, so it doesn't grow with the number of cores. (#1015, #320)
- When CodeGraph's MCP server runs with no default project of its own — started outside any repository (for example behind an MCP gateway), or at a monorepo root whose indexes live in sub-projects — it now marks `projectPath` as a required argument on every tool call. Before, `projectPath` was always optional, so an agent talking to such a server would often omit it, get back guidance to pass it, and not reliably retry — you had to nudge it by hand every time. Now the requirement is part of the tool definition the agent sees, so it supplies the path to the project it's working on the first time. When the server does have a default project — the normal case, launched inside your repo — `projectPath` stays optional and a call without it falls back to that project exactly as before. Thanks @wauxhall for the report. (#993)
- CodeGraph's MCP tools now work in Cursor's **Ask mode** (and any other client that only permits read-only tools). Every CodeGraph tool just reads your indexed code — it never changes your workspace — but it didn't advertise that, so Cursor's Ask mode blocked every call with "you are in ask mode and cannot run non read-only tools," and you had to switch to Agent mode to use CodeGraph at all. CodeGraph now declares all its tools read-only using the standard MCP tool annotations, so Cursor (and similar clients) allow them in read-only contexts. Nothing about how the tools behave changes. Thanks @CDsouza315 for the report. (#1018)

### Fixes

- A `codegraph index` or `codegraph init` that gets orphaned or wedged now stops itself instead of pinning a CPU core forever. If you killed the command (or the terminal/agent that launched it), the underlying indexer process used to keep running in the background — the parent couldn't pass the signal along — and a genuinely stuck index had nothing watching it either, since the self-recovery watchdogs were wired only into the background MCP server. Both gaps are closed: indexing now self-terminates when its parent goes away, and a main thread that stops making progress is killed so it can't hang indefinitely. Opt out with `CODEGRAPH_NO_WATCHDOG=1` (liveness) or `CODEGRAPH_PPID_POLL_MS=0` (orphan detection), matching the server. (#999)
- Indexing no longer hangs at "Resolving refs" on a repo that commits a large JavaScript/TypeScript theme or SDK. A vendored admin theme (Metronic is the classic case — ~1,300 committed `.js` files) re-declares the same method names (`init`, `update`, `render`, `destroy`, …) on hundreds of widgets, and resolution used to score *every* same-named definition against *every* call — work that grows with the square of how many times a name repeats. On such a repo it pinned a CPU core for 15–30 minutes and effectively never finished. Resolution now declines to guess when a name is defined more times than any real codebase ever repeats one (the cutoff is generous — normal projects top out far below it and are completely unaffected), since no proximity heuristic can pick the one true target among thousands anyway. Indexing that previously wedged now completes in seconds, and precise resolution (imports, qualified names, class-name matches) is unchanged. This is the same class of slowdown as the 1.1.0 import-name fix, now closed for repeated method/symbol names. Tune the cutoff with `CODEGRAPH_AMBIGUOUS_NAME_CEILING` if you ever need to. Thanks @DANOX2 for the detailed report and repro. (#999)
- Claude Code's front-load prompt hook now fires for non-English prompts. The optional hook that injects CodeGraph context for structural questions only recognized English keywords, so a structural question written in Chinese — or any non-Latin-script language — silently injected nothing: the hook looked like it wasn't wired up despite a correct setup, with no error to explain why. The gate is now language-aware. It recognizes Chinese structural keywords (如何/流程/调用/依赖/实现/架构…), and — in any language — a prompt that names a real code symbol from your project, such as `getUserId`, `article_publish`, `user.login`, or `parseToken()` (the name is checked against the index, so an ordinary word that merely looks like code doesn't trigger it). Non-structural prompts ("fix this typo", in any language) stay a no-op as before, so nothing fires where there's no structural answer to give. Thanks @whinc for the detailed report and repro. (#994)
- The background auto-sync server now starts for projects kept on an ExFAT or FAT external drive (and some network mounts). Those filesystems don't support the operations the server relies on to coordinate and to listen locally, so it failed immediately and re-logged the same error on every retry — background indexing was broken, so you had to run `codegraph sync` by hand after changes. (The MCP tools, the prompt hook, and manual `codegraph index`/`sync` were unaffected, since none of them need the server.) The server now works around those limitations automatically — falling back to a different coordination method and relocating its local socket to your system temp directory — so background indexing works there exactly like anywhere else, with no configuration needed. Verified end-to-end on real removable-drive filesystems on macOS, Linux, and Windows. Thanks @zengwenliang416 for the detailed report. (#997)
- If you use CodeGraph as a library, the `QueryBuilder.deleteResolvedReferences()` helper no longer throws "too many SQL variables" when handed a very large list of ids — it issued one unbounded query, so a list longer than SQLite's parameter limit aborted the call. It now splits the work into batches like every other bulk query in the API. CodeGraph's own indexing and reference resolution never called this method (they use a different, already-batched path), so the CLI and MCP server were unaffected. Thanks @inth3shadows for the static analysis. (#1001)
- Swift computed properties are now indexed, so you can search for them. A computed property — a `var isCloudProxy: Bool { … }` read all over a codebase, a SwiftUI view's `var body: some View { … }`, a protocol's `var title: String { get }` requirement — produced no symbol at all, so `codegraph query` and `codegraph_explore` answered "No results found" for it, and an agent that trusts an empty result would wrongly conclude the property doesn't exist. Computed properties (and protocol property requirements) are now graph symbols you can find and explore like anything else. A computed property's getter is also read as its body, so a SwiftUI view's `body` links to the subviews and helpers it builds — making a view's render flow traceable through the property. Stored properties were already indexed; this closes the computed-property gap. Thanks @monochrome3694 for the precise report and repro. (#1020)

## [1.1.1] - 2026-06-24

### Fixes

- CodeGraph respects your `.gitignore` again when looking for nested git repositories. A directory you've gitignored — a `resource/` or `.repos/` folder of cloned reference projects, a large vendored data dir — is no longer walked into and indexed: version 1.0.0 started searching inside *every* gitignored directory for embedded git repos and pulling them all in, which could multiply a graph many times over and slow indexing to a crawl on a multi-gigabyte folder of clones, even though you'd explicitly excluded it. Indexing the repos inside a gitignored directory is now opt-in — add an `includeIgnored` list to a `codegraph.json` at your repo root, e.g. `{ "includeIgnored": ["packages/", "services/"] }`, to index the embedded repos under the directories you name. The "super-repo of independent clones" layout from 1.0.0 still works, just declared explicitly. Nested repos you *haven't* gitignored (untracked clones) are indexed as before, and a project without this layout is unaffected. (#970, #976, #622)
- The MCP server no longer drops out with `Transport closed` when its connection to the shared background server hits a transient socket error. To serve all your editor/agent sessions from a single index, CodeGraph runs one shared background server they reach over a local socket; a stray error on that socket while a session was connecting used to take the whole server process down, so your agent saw a bare `Transport closed` even though `codegraph status` and `codegraph sync` were perfectly healthy. Now such an error is handled gracefully — the session falls back to serving itself in-process instead of crashing. This is most common on WSL2 when your project lives on a Windows drive (a `/mnt/c` or `/mnt/d` path), where that socket is flaky; if you still hit problems there, set `CODEGRAPH_NO_DAEMON=1` to skip the shared server entirely and run each session in its own process. Affects Codex and any other MCP client. (#974)
- A shared background server that can't bind its socket now cleans up its own lock file before exiting, instead of leaving a stale lock that the next launch trips over — which previously could let duplicate `serve --mcp` processes pile up for the same project. (#974)

## [1.1.0] - 2026-06-23

### New Features

- **Claude Code:** an optional front-load hook makes your agent reach for CodeGraph automatically. When you ask a structural question — "how does X work", "what calls Y", "trace the flow from A to B" — CodeGraph injects the relevant source and call paths into the prompt up front, so the agent answers from the graph instead of grepping around to rebuild it. You're asked during `codegraph install` (default yes; Claude Code only, since it's the agent with prompt hooks), it's removed by `codegraph uninstall`, and `codegraph upgrade` turns it on for existing Claude setups. It's strictly additive and degradable — non-structural prompts and un-indexed projects are left alone — and you can switch it off any time without uninstalling by setting `CODEGRAPH_NO_PROMPT_HOOK=1`.
- Vue store actions, mutations, and getters are now indexed as symbols you can find and read. Whether your store is **Vuex** (`mutations` / `actions` objects in a module) or **Pinia** — both the options form (`defineStore({ actions: { … } })`) and the setup form (`defineStore('id', () => { … })`, where actions are local functions) — each action, mutation, and getter is now a real node. So `codegraph search` finds `login` or `getSessionList`, and `codegraph_explore` / `codegraph_node` show its body and what it calls, instead of "not found" because the function only existed as an object-literal property.
- `codegraph_explore` now connects a Vue component to the **Pinia** store action it calls. When code does `const store = useUserStore()` and then `store.fetchUser()`, that call now links through to the `fetchUser` action in the store module — so "what happens when this view loads its data?" traces from the component into the action's body instead of stopping at the `store.fetchUser()` line. Works for both Pinia store styles (options and setup), and stays precise (a built-in like `store.$patch()` or an unrelated same-named method isn't mislinked).
- `codegraph_explore` now follows **Vuex** string dispatch. A `dispatch('user/login')` or `commit('SET_TOKEN')` call — namespaced `'module/action'` keys included — now links to the action or mutation it names, resolved to the correct store module even when several modules share an action name (and without being fooled by a same-named `api/` helper). So "what runs when this dispatches?" traces from the call into the store handler and on to the mutations it commits. Vuex's canonical `export default { namespaced, actions, mutations }` module shape is now indexed too, so those handlers are findable symbols.
- `codegraph_explore` now connects React data-fetching flows built on **RTK Query** (Redux Toolkit's `createApi`). An endpoint defined inside `createApi({ endpoints })` and the `useGetXQuery` / `useUpdateYMutation` hook it generates were both invisible to analysis — so "what does this component fetch?" or "where does `useGetThingQuery` get its data?" dead-ended, because the hook, the endpoint, and the component had nothing linking them. CodeGraph now indexes each endpoint and each generated hook as real symbols and wires the path `component → useGetXQuery → getX → queryFn`, so the flow resolves in one explore call instead of reading the API slice by hand. Both the arrow (`endpoints: build => ({ … })`) and method (`endpoints(builder) { return { … } }`) styles are recognized, along with the `useLazyGetXQuery` variant; hand-written hooks of a similar name are left untouched.
- `codegraph_explore` now follows **Celery** task dispatch in Python. A `send_email.delay(...)` or `send_email.apply_async(...)` call now links to the `@shared_task` / `@app.task` function it runs — typically defined in a different module (`tasks.py`) from where it's triggered (a view or service) — so "what actually happens when this is dispatched?" traces from the call site straight into the task body instead of stopping at the `.delay()` line. Both decorator dialects are recognized (bare `@shared_task` and the arg'd `@app.task(bind=True, …)` form), including the module-qualified `tasks.invalidate_cache.apply_async()` call style. It stays precise: a `.delay()` on something that isn't a Celery task is never mislinked, so a project that doesn't use Celery is unaffected.
- `codegraph_explore` now follows **Spring application events** in Java. A `publishEvent(new OrderShippedEvent(...))` call now links to every `@EventListener` that handles that event — usually in a different class — so "what reacts when this is published?" traces from the publisher straight into each listener method instead of dead-ending at `publishEvent(...)`. The link is by event type, and all the common listener styles are recognized: a `@EventListener` typed on its parameter, the `@EventListener(SomeEvent.class)` form, `@TransactionalEventListener`, and the older `implements ApplicationListener<SomeEvent>`. One event fans out to all its listeners, and a plain Spring app with no event bus is unaffected.
- `codegraph_explore` now follows **MediatR** request and notification dispatch in C#/.NET. A `_mediator.Send(command)` or `_mediator.Publish(notification)` call now links to the `Handle` method of the matching `IRequestHandler<>` / `INotificationHandler<>` — usually in a different file in a Clean Architecture layout — so "what handles this command?" traces from the controller straight into the handler instead of stopping at the mediator call. The sent type is recognized whether it's constructed inline (`Send(new GetFooQuery())`), built into a local first (`var cmd = new …; Send(cmd)`), or passed in as a parameter, and it's matched by type — so a `MessagingCenter.Send(...)` or a same-named DTO that isn't a request is never mislinked, and a project without MediatR is unaffected.
- `codegraph_explore` now follows **Sidekiq** background-job dispatch in Ruby. A `DestroyUserWorker.perform_async(id)` (or `.perform_in` / `.perform_at`) call now links to that worker's `perform` method — usually in `app/workers/` away from the controller or model that enqueues it — so "what runs in the background here?" traces from the enqueue straight into the job body. Both the modern `include Sidekiq::Job` and the older `Sidekiq::Worker` are recognized, namespaced workers resolve to the right class even when several share a name (e.g. `Comments::NotifyWorker` vs `Articles::NotifyWorker`), and Rails ActiveJob's `perform_later` — a different mechanism — is intentionally left alone.
- `codegraph_explore` now follows **Laravel events** in PHP. An `event(new OrderShipped($order))` call now links to every listener that handles it — each listener's `handle()` method, usually a separate `app/Listeners/` class — so "what reacts to this event?" traces from the dispatch straight into the listener bodies. Listeners are found both ways Laravel registers them: by a typed `handle(OrderShipped $event)` (auto-discovery, including a `handle(A|B $event)` union that listens for two events) and by the `protected $listen` map in your `EventServiceProvider` (which also catches a listener whose `handle()` has no type-hint). One event fans out to all its listeners, and queued jobs — dispatched via `::dispatch()` rather than `event()` — are correctly left out.
- CodeGraph now understands **Lombok**-generated methods in Java. `@Getter`, `@Setter`, `@Data`, `@Value`, and `@Builder` generate getters, setters, `builder()`, `equals`/`hashCode`/`toString`, and the `@Slf4j` `log` field at compile time, so those methods never appear in the source — and a `user.getName()`, `User.builder()`, or `log.info(...)` call used to resolve to nothing, silently breaking call-chain analysis (the agent would conclude the method didn't exist and reconstruct it by hand). Those members are now indexed from the annotations and fields, so they appear in `codegraph search` and `codegraph_explore`/`codegraph_node`, and callers trace through them like any hand-written method. They're marked as Lombok-generated so they read as generated, not hand-written; a method you write yourself is never overridden, static fields get no accessor, and a class without Lombok is unaffected. Thanks @git87663849. (#912)
- `codegraph_explore` now follows **C and C++ function-pointer dispatch**. C does polymorphism with function pointers: a struct carries a function-pointer field, concrete functions are registered into it through a table (`static struct cmd commands[] = {{"add", cmd_add}, …}`), a designated initializer (`.handler = on_open`), or an assignment, and the code dispatches indirectly (`p->fn(argv)`). None of that was visible to analysis — the indirect call resolved to nothing, so `git`'s command runner looked like it called nothing and a vtable's implementations had no callers. CodeGraph now links the dispatch site to the registered handlers, keyed by the struct field, so "what runs when this dispatches?" traces from `p->fn(...)` into every function registered for that field. This covers the command-table idiom (git, redis) and the ops-struct/vtable idiom (curl's content-encoders, protocol handlers), including the case where a generic hook slot is reassigned from a registry (`h->func = found->fn`). It stays precise — distinct function-pointer fields don't cross-link, a plain data field is never treated as a dispatch, and a project without function-pointer dispatch is unaffected. (#932)
- `codegraph_explore` now follows **GoFrame** route bindings in Go. GoFrame's standard router wires routes reflectively: the path and method live in a `g.Meta` struct tag on a request type (`` g.Meta `path:"/user/sign-in" method:"post"` ``), the controller method that serves it is matched by that request type, and the two are joined at runtime by `group.Bind(...)` — so there was no path string and no edge from a route to its handler, and "where is `/user/sign-in` handled?" or "where are the routes bound to controllers?" could only be answered by reading. CodeGraph now indexes each `g.Meta` route as a real route node and links it to the controller method whose signature takes that request type, so a route resolves to its handler structurally in one `codegraph_explore` call. The link is by request type, not method name — so it's correct even when the two differ (a `DeptSearchReq` served by a `List` method); it tells apart the many identical request types a large app defines one-per-module (`cash.ListReq` vs `order.ListReq`) by package, including cloned addon modules; and a route whose handler isn't present is left unlinked rather than guessed. (#747)
- The MCP server now works in monorepos and multi-project setups. Before, if you started CodeGraph somewhere with no `.codegraph/` of its own — most often a monorepo root where you only indexed individual services — the server exposed **no tools at all**, so your agent couldn't query CodeGraph even for the sub-projects that *were* indexed. Now the tools are always available: point a query at any indexed project with the `projectPath` argument (its path, or anywhere inside it) and CodeGraph answers from that project's index — for as many projects as you like in one session. It also means a project you index *after* the server started is picked up without restarting, where before the tools stayed hidden because the server only checked for an index once at launch. A project that genuinely has no index still cleanly tells your agent to use its built-in tools there (and that you can run `codegraph init` to enable it), so single-project use is unchanged. Thanks @MaiLunJiye. (#964)
- The Claude front-load hook now finds your indexed sub-projects in a monorepo. The optional `UserPromptSubmit` hook that injects CodeGraph context for structural questions previously only looked for an index at or above your working directory — so if you opened the monorepo root but indexed individual packages (`packages/api`, `services/auth`), it found nothing and stayed silent exactly where it was most useful. It now also looks *into* sub-projects: a single indexed sub-project gets its context front-loaded automatically, and with several the hook front-loads the one your question names (and lists the rest so the agent can target them by `projectPath`). Single-project repos are unaffected, and the scan is bounded and skipped entirely outside a recognizable workspace root. (#964)

- `codegraph_explore` now surfaces the right code in large multi-layer projects. When you ask a backend-flow question in a repo that pairs an API server with a big frontend that mirrors the same domain words — say an `app/` admin UI sitting over an `api/` server — the server-side file that genuinely matches several of your query's terms is no longer pushed out of the results by the larger, more interconnected frontend layer. A file corroborated by two or more distinct query terms is now kept in the answer even when a denser unrelated layer would otherwise crowd it out, so "how does X read items / handle the request" returns the service or handler that does the work instead of a wall of frontend views. Single-layer projects are unaffected; set `CODEGRAPH_RANK_NO_MULTITERM=1` to revert to the previous ranking.
- Impact and blast-radius analysis for TypeScript, JavaScript, Go, Python, Rust, Ruby, C, Java, C#, PHP, Scala, Kotlin, Swift, Dart, and Pascal/Delphi now understands the readers of a constant. When you change a file-scope, package-level, module-level, or class-level constant — a config object, a lookup table, a shared constant — the other symbols in that file that read it now show up as affected, where before they were invisible (impact only followed calls, imports, and inheritance, so a constant's consumers looked like "nothing depends on this"). This makes `codegraph impact`, and the impact trail in `codegraph_explore`/`codegraph_node`, catch the "change this table, break its readers" class of change. It's on by default and adds no nodes to your graph; bundled/minified files and ambiguously-shadowed names are skipped to keep results precise. Set `CODEGRAPH_VALUE_REFS=0` to turn it off.
- C file-scope constants and globals — `static const` scalars, pointer/array lookup tables, and shared mutable globals — are now recognized as symbols in their own right. They previously weren't extracted at all, so they never appeared in search or carried any dependents; now they show up in `codegraph search` and participate in impact analysis (see above), so changing a C lookup table surfaces the same-file functions that read it.
- Java `static final` constants, C# `const` / `static readonly` constants, Scala `object` vals, and Kotlin top-level / `object` / `companion object` `val`s are now classified as constants rather than generic fields, so they participate in the constant-reader impact analysis above — change a `public static final` table, a `const string`, a Scala `object Config { val Timeout = … }`, or a Kotlin `companion object { const val … }` and the methods that read it now show up as affected. (Per-object Java `final` / C# `readonly` / Scala & Kotlin `class` instance properties are unchanged.) Kotlin constants were previously not indexed as their own symbols at all, so they now also appear in `codegraph search`.
- Swift top-level `let`s and `static let` constants (including those namespaced in an `enum`/`struct`, the common Swift pattern) are now indexed as constants and participate in the constant-reader impact analysis above — change a `static let defaultRetryLimit` or an `enum Constants { static let … }` and the same-file code that reads it shows up as affected. Computed properties and per-instance `let`s are not treated as constants.
- Dart top-level `const`/`final` and class `static const`/`static final` constants are now indexed as constants and participate in the constant-reader impact analysis above. Instance fields, `var`s, and locals are not treated as constants. (Generated Dart code with the standard `.g.dart`/`.freezed.dart`/`.pb.dart` suffixes is already skipped.)
- You can now teach CodeGraph about custom file extensions. Drop a `codegraph.json` at your repo root with an `extensions` map — `{ "extensions": { ".dota_lua": "lua", ".tpl": "php" } }` — and files with those extensions get indexed under the language you name, instead of being silently skipped because the extension wasn't one of the built-in defaults. It's opt-in and committed alongside your code so the whole team shares it, your mappings layer on top of the built-ins and win on conflict (you can even re-point a built-in, e.g. `.h` → `cpp`), and a typo'd language or a malformed config is warned about and skipped rather than breaking indexing. Projects without a `codegraph.json` behave exactly as before. (#906)

### Fixes

- `codegraph index` and `codegraph init` no longer crawl during the "Resolving refs" phase on large projects — most painfully ones that mix a big front-end and back-end, where the phase could stretch to many minutes. A package or module imported across hundreds or thousands of files (`react`, a shared UI package, Python `logging` / `typing`) was being treated as if every one of those import statements might be its definition, so the resolver compared each import against all the others — work that grows with the *square* of how widely a package is imported, which is why it blew up only on big, import-heavy repos. Imports now resolve straight to the definitions they actually point at, so those redundant comparisons are gone (reference resolution is dramatically faster on large repos), and the graph no longer accumulates the meaningless import-to-import links the old fallback created. (#915)
- MCP tool results no longer show up as oversized headings in Markdown-rendering clients (such as the Claude Code VSCode extension). Results used Markdown headings (`##`/`###`) for things like the status summary, each search hit, and every file section in an exploration, so a normal query filled the transcript with large-font lines — worst with `codegraph_search` and `codegraph_explore`, where the noise grew with the number of results. Section headers are now bold labels, which render at normal text size while keeping the same structure. Terminal/CLI output is unchanged. (#778)
- An MCP server pointed at a very large repository (tens of thousands of files) no longer hangs on the first tool call after a fresh start. On startup CodeGraph reconciles its index against the current files on disk, and on a huge repo that reconcile could run for minutes while blocking the very first request — long enough that the background server was sometimes force-restarted mid-scan, so the first query never came back at all. The reconcile now yields as it runs (keeping the server responsive instead of pinning it), and the first tool call waits only briefly for it before answering and letting the rest finish in the background — so you get a fast first response and the index still catches up. Set `CODEGRAPH_CATCHUP_GATE_TIMEOUT_MS` to tune how long that first call waits (default 3000ms), or `=0` to always wait for the full reconcile. (#905)
- `codegraph install` now wires up your agents and stops there — it no longer indexes the current directory. Building a project's graph is always the explicit `codegraph init` (or `codegraph index`), so you decide what gets indexed and when, and the steps are the same whether you installed globally or just for one project. This clears up the confusion where a project-local install silently indexed but a global one didn't, and where the docs and the tool disagreed about whether you still had to run `init`. (#826)
- React components declared with `forwardRef`, `memo`, or styled-components / emotion (`const Button = forwardRef(...)`, `const Card = memo(...)`, `const Box = styled.button\`…\``) are now recognized as components, so finding where they're used works. Before, they were indexed as plain constants, so `codegraph callers` and impact analysis reported "no callers found" even when the component was rendered across dozens of files — a dangerous false "safe to change" right before refactoring a shared component. Now every `<Button/>` usage links back to the component, so callers and blast radius are complete. This is the standard shadcn/ui declaration style, so for typical React design systems the whole UI layer is no longer invisible to impact analysis. Thanks @Arlandaren for the report and @maxmilian for the root-cause. (#841)
- React Router and Next.js routes defined in `.tsx` / `.jsx` files are now indexed. Routes written as JSX — `<Route path="/users" element={<UsersPage/>}/>`, `createBrowserRouter([...])`, and Next.js `app/`/`pages/` page files — were being skipped entirely (only routes that happened to live in plain `.ts`/`.js` were picked up), so "what renders at this path?" and the route → page-component link were missing for most React apps. Now those routes show up in `codegraph search`/`codegraph_explore` and connect to the component they render, just like the backend route → handler links on other frameworks.
- `codegraph sync` (and the file-watcher auto-sync behind always-on / MCP use) no longer drops a function's callers when you edit the file that function lives in. Re-indexing a file after an edit — even a docstring-only change — was severing the `calls` / `references` edges coming from *other, unchanged* files (e.g. `from pkg import mod; mod.fn()` callers, or any cross-file reference), so `codegraph callers` / `impact` would abruptly report "no callers" for a function that's used throughout the codebase, until the next full re-index. Sync now preserves those incoming cross-file edges across the re-index, re-matching them to the symbol even when the edit shifted its line number. Most visible in large Python package trees, but it applies to every language. Thanks @JosefAschauer. (#899)
- `codegraph index` now rebuilds the full graph from scratch, so it produces the same result as a fresh `codegraph init` instead of reporting "0 nodes, 0 edges" and looking like it wiped your index. Previously, re-running `index` on an unchanged project skipped every file (their contents hadn't changed) and showed an empty-looking summary; it now clears and re-indexes for an honest, complete rebuild every time. Use `codegraph sync` for fast incremental updates between full rebuilds. Thanks @Arc-univer. (#874)
- The file watcher that auto-syncs the graph now fails cleanly when live watching can no longer be trusted, instead of looking healthy while the index quietly goes stale. If the operating system runs out of file-watch resources, or another process holds the write lock far longer than a normal save, CodeGraph now disables auto-sync once — with a single clear message telling you to run `codegraph sync` (or rely on the git sync hooks) to refresh — rather than retrying forever or repeating the same error on a loop. And while auto-sync is disabled, CodeGraph's tool responses (and `codegraph status`) now say so plainly, so your AI agent knows to read files directly instead of trusting a frozen index. This mostly matters for long-running MCP/daemon sessions, which could otherwise keep serving stale results while appearing to work. Thanks @thismilktea. (#876)
- On Linux, hitting the kernel's inotify watch limit on a large project no longer silently leaves half the tree unwatched. CodeGraph now tells you once — naming the exact setting to raise (`fs.inotify.max_user_watches`, e.g. `sudo sysctl fs.inotify.max_user_watches=1048576`) — and keeps live-watching the directories it could register while `codegraph sync` (or the git sync hooks) covers the rest. (#876)
- A long-running MCP server now notices when a git worktree gains its own index. Before, if the server (or shared daemon) first saw a worktree before you ran `codegraph init` in it — so the lookup walked up to the main checkout's index — it pinned that decision for its whole life: even after the worktree had its own `.codegraph/`, every query kept hitting the main checkout's index and every result carried a false "this index belongs to a different git working tree" warning, until you restarted the server. The CLI got it right but the MCP server didn't, and re-indexing didn't help. The server now re-checks which index a path belongs to on each call, so the worktree's own index is picked up — and the stale warning drops — without a restart. (#926)
- A long-running MCP server now recovers when your index is deleted and rebuilt at the same path. If `.codegraph/` was removed and recreated while the server held it open — most easily by recreating a git worktree at the same path, or `rm`-ing `.codegraph/` and running `codegraph init` again — the server kept reading the old, deleted database file and served a frozen snapshot: renamed or removed symbols still showed as live, new ones were missing, and `codegraph sync` couldn't refresh it — only restarting the server fixed it. The server now detects that the database file was swapped out from under it and reopens the live one in place, so results stay correct without a restart. (On Linux and macOS; Windows doesn't allow deleting an open file, so it isn't affected.) (#925)
- The MCP server now opens and auto-syncs a project that lives inside a folder an enclosing git repository ignores. Before, if the directory you indexed sat within a larger repo that gitignored it, the shared MCP daemon failed to open the project — its log repeated `Failed to open project … path should be a` `path.relative()` `d string, but got "./"` — so the file watcher never started and the index silently went stale until you ran `codegraph sync` by hand (setting `CODEGRAPH_NO_DAEMON=1` was the only workaround). The daemon now opens the project and starts watching as expected. Most visible with Codex on Windows, but the cause wasn't platform-specific. (#936)
- A git worktree of a submodule is no longer indexed as a duplicate copy of that submodule's code. CodeGraph already skips ordinary worktrees (a second working view of a repo it indexes), but a worktree created *from a submodule* — common in monorepos that check submodules out into worktrees for parallel feature work — was mistaken for a genuine embedded repo and swept in, duplicating every symbol it shared with the real submodule checkout (one report had ~28% of its index as duplicates, inflating both query results and the database). These submodule worktrees are now recognized and skipped, while the submodule's own checkout stays indexed as distinct code. Thanks @charlesxu2026-ship-it. (#945)
- A C++ class or struct annotated with an export/visibility macro — `class MYLIB_EXPORT Foo : public Bar { … }`, the common DLL-export / visibility pattern in headers — is no longer mis-indexed as a function spanning the whole class body. Not knowing the macro is a macro, the parser read it as a type and the whole declaration as a function, so the class surfaced as a phantom `function` that showed up as a false caller in `codegraph callers`, `codegraph impact`, and blast-radius analysis, and skewed symbol counts. CodeGraph now recognizes this misparse and drops the bogus node. Thanks @spwlyzx. (#946)
- `codegraph status` no longer reports phantom pending changes for files CodeGraph deliberately keeps out of the index — a tracked file inside a committed dependency dir (a checked-in `vendor/` or `node_modules/`), or a tracked file under a `.gitignore`d directory. A full index correctly excludes these, and `codegraph sync` never indexes them, but the fast change-detector behind `codegraph status` flagged every edit to such a file as "modified" (and a new one as "added") — so the pending-changes count never cleared no matter how many times you synced. Change detection now applies the same ignore rules the full index does, so `status` agrees with `sync`, and tools built on CodeGraph's change-detection API get the same corrected list. (#766)
- Files reached through a symlinked directory that points outside your project now index instead of being silently skipped. When a folder in your repo is a symlink to a location outside the repo root — the standard layout for Dota 2 custom games and similar SDK-linked projects, where `game/` and `content/` link into the engine tree — CodeGraph followed the symlink to discover those files but then blocked every one of them while reading, logging `Path traversal blocked in batch reader` and indexing nothing under them. The reader now agrees with the directory scan and indexes those files. The guard against `../` path escapes is unchanged, and the protection that keeps your agent from being served file contents from outside the repo is also unchanged — only the indexer's own read path follows these in-repo symlinks. (#935)

## [1.0.1] - 2026-06-13

### New Features

- New `codegraph daemon` command (alias `daemons`) — an interactive manager for the background daemons. It shows what's running (your current project's daemon first, pre-selected), and you arrow-key to one and press enter to stop it, or pick "Stop all". Previously the only way to shut a daemon down was to hunt for its pid and `kill` it by hand. (#845)
- Checking your installed version is now easy to reach however you guess at it: `codegraph version`, `codegraph -v`, and `codegraph -version` all print it, alongside the existing `codegraph --version`. (#864)
- The CodeGraph MCP server now self-heals if its main thread ever locks up. A lightweight watchdog notices when the process has stopped responding and stops it so a fresh one starts on your next request — it can no longer sit pinned at 100% CPU with no way to recover. Tune the detection window with `CODEGRAPH_WATCHDOG_TIMEOUT_MS`, or turn it off entirely with `CODEGRAPH_NO_WATCHDOG=1`. (#850)

### Fixes

- Git worktrees nested inside your project — like the `.claude/worktrees/` that Claude Code creates — are no longer indexed as duplicate copies of your whole codebase. CodeGraph deliberately indexes genuine embedded repos (a real second project checked out inside yours), but a worktree is just another working view of a repo it already indexed, so each one was multiplying every symbol — one report went from ~1,850 files to over 24,000, with search and `explore` flooded by stale duplicates. CodeGraph now recognizes worktrees and skips them, while still indexing real embedded repos and submodules. Thanks @tphakala. (#848)
- Running `codegraph serve --mcp` by hand no longer just hangs in silence. That command is the MCP server your AI agent starts for itself — not a step you run directly — and in a terminal it used to sit there waiting for input that never comes, looking broken. It now recognizes when a person runs it and explains what to do instead (`codegraph status`, `codegraph daemon`), and it's been dropped from the command listing so it stops looking like something you need to launch.
- Cross-file static method calls like `ClassName.staticMethod()` now resolve correctly. CodeGraph was linking the call to the *class* instead of the method (and recording it as a construction), so `callers` and `impact` for a static method came back empty — a real blind spot in TypeScript and JavaScript codebases that lean on static utility classes (Python and other languages with the same call shape benefit too). The call now links to the method itself. Thanks @contextFlow-lab. (#825)
- `codegraph affected` now accepts `./`-prefixed and absolute file paths, not just bare project-relative ones. Passing `./src/x.ts` or an absolute path — common when the file list comes from another tool — used to silently match nothing and report no affected tests. Thanks @contextFlow-lab. (#825)
- The CodeGraph MCP server no longer risks getting stuck at 100% CPU after an unexpected internal error. Previously such an error was logged but the process was left running in a broken state, where it could spin a CPU core indefinitely and had to be killed by hand. The server now logs the error and exits cleanly, so a fresh one starts on the next request. Thanks @songhlc. (#850)
- CodeGraph no longer indexes your entire home directory by accident. Running the installer — or `codegraph init` / `codegraph index` — from your home folder or a filesystem root would index everything underneath it (caches, `Library`, every other project), producing a multi-gigabyte index and constant file-watching churn. CodeGraph now refuses these roots and points you at a specific project instead; pass `--force` if you genuinely mean to. (Combined with the macOS file-descriptor fix already in 1.0.0, this closes the report of a runaway watcher exhausting the system file limit.) Thanks @ligson. (#845)

## [1.0.0] - 2026-06-12

### Security

- Closed a path-traversal hole where a symbolic link inside an indexed project that pointed *outside* the project root could make CodeGraph serve that out-of-root file's contents (for example a file under your home directory) to the AI agent. CodeGraph now resolves symlinks when validating file access and refuses to read anything whose real location is outside the project, while still allowing symlinks that stay within it. Thanks @sulthonzh. (#527)
- CodeGraph now indexes Spring configuration files (`application.properties` / `application.yml`) by key only, and never includes their values in `codegraph_explore` or `codegraph_node` output. Previously a secret committed to one of these files — a database password, API key, or connection string with embedded credentials — could be surfaced to an AI agent that asked about nearby code, even though the agent never opened the file. The configuration keys are still indexed, so reference and impact analysis are unaffected; an agent that genuinely needs a value reads the file itself. Shopify Liquid `{% schema %}` blocks are likewise indexed by name only. (#383)

### New Features

- **CodeGraph now indexes R** (`.R` / `.r`) — functions in every assignment form (`name <- function(...)`, `name = function(...)`, nested definitions), S4 / Reference / R6 classes with their methods, `setGeneric`/`setMethod` generics, top-level variables and constants, `library()` / `require()` imports, `source()` file references, and call edges — including calls inside tidyverse pipe chains. Statistical and research codebases get the full explore / impact / callers surface. (#828) (R)
- **Workspaces holding multiple git repositories now index as a whole.** Running `codegraph init` at the root of a directory that contains several independent git repos — including the common "super-repo" layout where the parent repo's `.gitignore` hides the child repos to keep `git status` quiet — now indexes every nested project into one graph, with each child repo's own `.gitignore` respected. `codegraph sync` and live file watching pick up changes inside the nested repos too (previously change detection only consulted the parent repo, so edits in child repos were invisible until a full re-index). Git repositories inside `node_modules` (npm git-dependencies) remain excluded. (#514)

- **`codegraph_explore` now explains where a flow ends instead of going silent.** When the symbols you ask about don't connect statically — because the code dispatches through a runtime mechanism like a computed call (`handlers[action.type](...)`), Python's `getattr`, a command/mediator bus (`sender.Send(new DeleteCommand(...))`), reflection, or `new Proxy` — explore now announces the exact dispatch site (file and line) where the static path stops, and when the dispatch key is visible in the source it shortlists the likely runtime targets (for example pointing a MediatR command straight at its `Handler.Handle` method). Detection is deterministic and runs only when a flow fails to connect; fully connected flows are unchanged, and nothing about indexing or the graph itself changes. Relatedly, a custom event bus whose emit and handler connect through a single synthesized hop now shows that hop explicitly (with the registration site) — it previously rendered nothing because the connection was "too short" for the flow section. (#687)

- **Anonymous usage telemetry, documented field-by-field and easy to turn off.** CodeGraph now collects a small set of anonymous usage statistics — which commands and MCP tools get used, which languages get indexed, which agents connect — so language and agent support work goes where real usage is. Never any code, file paths, file or symbol names, search queries, or IP addresses; usage aggregates locally into daily totals before anything is sent, and the ingest endpoint is public, auditable code in the repository that enforces the documented field list. The installer asks up front with a visible default-on toggle (and never re-asks); everywhere else a one-line notice prints before the first send. Disable any time with `codegraph telemetry off`, `CODEGRAPH_TELEMETRY=0`, or the cross-tool `DO_NOT_TRACK=1` standard — off means off: nothing is recorded, nothing is sent, and buffered data is deleted. `TELEMETRY.md` documents every field.
- **Subagents and non-MCP agents can now reach CodeGraph.** Two new CLI commands — `codegraph explore "<symbols or question>"` and `codegraph node <symbol-or-file>` — print exactly what the matching MCP tools return (relevant symbols' source + call paths; one symbol's source + callers; file reads with line numbers), so any agent with a shell can use the graph. And `codegraph install` now writes a small marker-fenced CodeGraph section into each agent's instructions file (`CLAUDE.md` / `AGENTS.md` / `GEMINI.md`) pointing at both surfaces — that file is what Task-tool subagents actually see, where the MCP server's own guidance only reaches the main agent. Measured on a delegated code-exploration task: subagents went from almost never using CodeGraph (~1 in 9 runs) to using it in every run, including runs with zero grep/file-reading fallback. The section is small, survives your own content, upgrades cleanly from the old long block, and `codegraph uninstall` removes it. Thanks @liuyao37511. (#704)
- **The MCP tool list is now a focused default of four** — `codegraph_explore`, `codegraph_node`, `codegraph_search`, and `codegraph_callers`. The other four (`codegraph_callees`, `codegraph_impact`, `codegraph_files`, `codegraph_status`) remain fully functional — the CLI and library API are unchanged, and `CODEGRAPH_MCP_TOOLS` re-enables any of them — but they're no longer listed to agents by default: measured agent behavior shows they're never or rarely picked, and the information they carry already arrives inline on the tools agents do use (explore's blast-radius section, node's dependents note, a symbol's own body as its callee list). A leaner list saves context tokens every session and steers agents to the right tool by presence alone.
- **CodeGraph now goes quiet instead of failing loudly in unindexed projects.** When an AI agent's session starts in a workspace that has no CodeGraph index, the MCP server now announces itself as inactive with a short note and lists no tools at all — instead of presenting the full toolset and erroring on every call, which taught agents to distrust CodeGraph even where it works. Querying another project that isn't indexed likewise returns clear guidance (use your regular tools for that codebase; the user can run `codegraph init` there to enable CodeGraph) instead of an error, and genuine internal errors now tell the agent to retry once rather than give up on CodeGraph entirely. Indexing stays your decision — agents are told not to run it themselves. (#769)
- **Astro projects are now indexed.** `.astro` files previously weren't parsed at all — on a typical Astro site that left most of the codebase invisible to search, impact, and `codegraph_explore`. CodeGraph now extracts the TypeScript frontmatter (functions, imports, `getStaticPaths`, …) and client-side `<script>` blocks, captures function calls and `<Component>` usages in template markup so cross-component dependencies trace end-to-end, resolves the `Astro` global and `astro:*` module imports as framework-provided, and maps `src/pages/` file-based routing to route nodes (`.astro` pages and `.ts` endpoints, including `[param]` and `[...rest]` dynamic segments, with underscore-prefixed files correctly excluded). Validated on two real-world Astro sites with 93% measured cross-file coverage and every page mapping to its route. Thanks @xingwangzhe. (#768) (Astro)
- Same-named symbols across a monorepo's apps are no longer conflated. In a NestJS-style workspace with one `UserService` per app, `codegraph_callers`, `codegraph_callees`, and `codegraph_impact` now report **one section per distinct definition** — each app's callers and blast radius under its own file-labeled heading — instead of a single merged list, and accept a `file` argument to focus exactly the definition you mean (like `codegraph_node` already did). Impact in particular no longer overstates a change's blast radius by merging unrelated same-named classes. Thanks @Igorgro. (#764)
- Fixed a related source of cross-package wrong edges: PascalCase **type references from plain `.ts` files were being resolved as React components**, which could link a file's own type alias to an arbitrary same-named class in another package (on one large monorepo this produced over a thousand wrong cross-package reference edges; 96% are now gone, and the remainder are genuine shared-model imports). Component resolution now applies only to references from JSX-capable files and never guesses between multiple candidates without a positional signal. The **Svelte and Vue component resolvers had the same arbitrary-pick flaw** (Vue resolved the first same-named `.vue` file found anywhere in the tree) and now follow the same rule: same-directory first, otherwise only an unambiguous name resolves. Re-index a project to benefit. (#764) (TypeScript, React, Svelte, Vue)
- TypeScript and JavaScript **class fields are now reported as properties instead of methods**. A plain field like `public fonts: Fonts;` previously extracted as a method, misrepresenting class shape and letting calls to same-named functions resolve to data fields (a boolean field named `isArray` was soaking up `Array.isArray(...)` call edges). Fields holding arrow functions or function expressions (`onClick = () => {…}`, including wrapped ones like `onScroll = throttle(() => {…})`) correctly remain methods and their bodies are still analyzed. Field initializers are analyzed too, so `history = createHistory()` records its call — and JavaScript class fields, which previously produced no symbol at all, now appear in the graph. Re-index a project to benefit. (#808) (TypeScript, JavaScript)
- Callback registration through `this` now resolves precisely in TypeScript and JavaScript: `window.addEventListener("online", this.onOfflineStatusToggle)` or an API object like `{ mutateElement: this.mutateElement }` produces a reference edge to the **enclosing class's own method** — never a same-named method on an unrelated class, and never a data field. Builds on the callback-registration support below. (#808) (TypeScript, JavaScript)
- Callback-registration coverage deepened across four more shapes: a `this.<member>` registration whose method lives on a **base class** now resolves through the inheritance chain (`bus.on("submit", this.handleSubmit)` in a subclass links to the parent's `handleSubmit`); Java and Kotlin **method references to other classes** (`Handlers::onMessage`, `OtherClass::handle`) resolve across files, with `this::` and `super::` scoped to the defining class and references through a variable deliberately left out; and Swift bare callback names now match only the **enclosing type's** methods (implicit `self`), eliminating a class of wrong edges where a parameter like `request` linked to a same-named method on an unrelated type. (Java, Kotlin, Swift, TypeScript, JavaScript)
- PHP **string and array callables** now register: a string passed to a callable-taking core function (`usort($items, 'cmp_items')`, `array_map('absint', …)`, `call_user_func`, `spl_autoload_register`, …) links to that function — including across files — and the array forms `[$this, 'method']` and `[Foo::class, 'method']` link to the named method (the `$this` form resolves through the class and its parents). Strings passed to arbitrary functions are deliberately ignored: only known callable positions are trusted. Validated on WordPress core (+556 edges, every sampled edge a genuine registration). (PHP)
- Ruby **lifecycle-hook symbols** now register: `before_action :authenticate`, `after_save :reindex`, `around_create`, `validate :check`, `rescue_from(…, with: :handler)` and friends link the symbol to the method it names — on the class itself or **inherited from a parent** (`before_action :authenticate` in a controller resolves to `ApplicationController`'s method). `validates` (plural) is excluded since its symbols name attributes, not methods. Validated on rails/rails (+385 edges, every sampled edge genuine). (Ruby)
- Method references to a type that needed **no import** now resolve: Java/Kotlin same-package references (`.concatMapMaybe(Maybe::just, …)`), **Kotlin companion-object members** (`KtHandlers::handle`), and cross-file C++ member pointers (`&TestSuite::RunSetUpTestSuite`). Resolution stays anchored to the named type, so a same-named member on a different class never matches. (Java, Kotlin, C++)
- CodeGraph now sees where a function is **registered as a callback**, not just where it's called. A function name passed as an argument (`signal(SIGINT, handler)`, `qsort(…, compare)`, `addEventListener(…, onBlur)`), assigned to a function pointer or field (`ops->recv_cb = my_cb`, `OnClick := Handler`), or placed in a struct initializer or handler table (`{ .recv_cb = my_cb }`, `{ "get", getCommand }`) now produces a reference edge from the registration site to the function — so `codegraph_callers` and `codegraph_impact` surface callback wiring that previously looked like dead code. Works across all supported languages, including the language-specific forms: C/C++ `&fn`, Java `Class::method`, Kotlin `::fn`, Swift `#selector`, Objective-C `@selector`, Ruby `method(:fn)`, Scala eta-expansion, and Delphi/Pascal `@Handler` and `OnClick := Handler` event wiring. Callers output labels these "via callback registration". Resolution is deliberately conservative: an ambiguous name produces no edge rather than a wrong one. Re-index a project to benefit. Thanks @zmcrazy. (#756)
- The `codegraph_node` MCP tool can now **read a whole source file like the built-in Read tool — only faster, served from the index**. Pass a file path with no symbol and it returns that file's current source with line numbers (the same `<n>⇥<line>` shape Read produces, so an assistant can edit straight from it), narrowable with `offset`/`limit` exactly like Read, plus a one-line note of which files depend on it (the file's blast radius). Use it anywhere you'd reach for Read on an indexed source file. Pass `symbolsOnly: true` for just the file's structure. Configuration/data files (`.yml` / `.properties`) are summarized by key only, never dumped, so secrets in them are never surfaced. The agent-facing guidance was also retuned so assistants reach for codegraph while *implementing* a change (not only when answering questions), since one codegraph call returns the same bytes plus the blast radius, faster than re-reading the file.
- New `codegraph upgrade` command updates CodeGraph to the latest release in place — it detects how you installed (the standalone `install.sh` / `install.ps1` bundle, npm, or npx) and does the right thing for each, on macOS, Linux, and Windows. Use `codegraph upgrade --check` to see whether an update is available without installing, or `codegraph upgrade <version>` to move to a specific version. After upgrading it reminds you to re-index your projects so they pick up the newer engine's improvements. (#679)
- `codegraph status` now flags when a project's index was built by an older engine than the one you're running and recommends re-indexing (also surfaced in `codegraph status --json`), so you know when a `codegraph index -f` or `codegraph sync` will add coverage a newer release introduced.
- Cross-file impact and blast-radius coverage now spans **all 22 supported languages and 14 web frameworks**, each validated on a real-world repo — see the new coverage table in the README. This release ships the cross-file resolution behind it, including Lua and Luau `require`, Shopify OS 2.0 Liquid section templates, Delphi form code-behind, Rust cross-module calls and Rocket route macros, Swift Fluent relationships, and the SvelteKit / Nuxt / Vapor / Axum route conventions. The residual everywhere is genuine static-analysis frontiers (runtime dispatch, reflection / DI, framework-convention entry points), never hidden.
- C# `record struct` and `readonly record struct` declarations now index with the correct `struct` kind, and positional one-liner records (`public record struct Money(decimal Amount);`) index reliably in every form — previously a bodiless value-type record could be skipped entirely and could halt extraction of the declarations following it in the same file. (#831) (C#)
- C# types are now tracked by their namespace-qualified name. Same-named types in different namespaces — a domain entity and a DTO both called `CatalogBrand`, say — are told apart instead of collapsing into one arbitrary match, so a reference resolves to the right one and impact no longer conflates them. (C#)
- ASP.NET Razor (`.cshtml`) and Blazor (`.razor`) markup are now parsed for code relationships. A `@model` / `@inherits` / `@inject` directive links the view to the C# view-model, base type, or service it names; a Blazor `<MyComponent/>` tag (plus `@typeof(...)` and generic `TItem="..."` arguments) links to the component class; and the C# inside `@code { }` / `@functions { }` / `@{ }` blocks is analyzed too, so services and types used in component logic are linked. A view-model, component, or service referenced only from markup is no longer reported as having no dependents, and editing it surfaces the views that use it. (ASP.NET, Blazor)
- A Razor/Blazor type reference now resolves through the component's `@using` namespaces — including the folder's cascading `_Imports.razor` — so a simple name that exists in several namespaces lands on the right one. A `@model` / `<MyComponent>` / `@code` reference to `CatalogBrand` resolves to the `@using`'d DTO (`BlazorShared.Models.CatalogBrand`) rather than a same-named domain entity. (ASP.NET, Blazor)
- `codegraph status --json` now also reports the running CLI `version`, the index directory (`indexPath`), and a `lastIndexed` timestamp (ISO-8601, or null when nothing's indexed yet), so CI and scripts can pin the CLI version and check index freshness from a single command. A matching `CodeGraph.getLastIndexedAt()` library method exposes the same freshness check without shelling out. Thanks @12122J and @eddieran. (#329)
- TypeScript service/RPC contracts defined as a tuple of generic types — `type MyServiceList = [Service<'query_apply_record', …>, Service<'apply_confirm', …>]` — now index each entry's string-literal name as a searchable symbol. Previously these names existed only as type arguments, so `codegraph query query_apply_record` found nothing even though the names are the app's primary API surface. The pattern is common in typed RPC / BFF clients and mock servers where the types are the source of truth for a runtime proxy object. Utility types (`Pick`, `Omit`, `Record`) and route paths are deliberately left out to avoid noise. Thanks @jiezhiyong. (#634) (TypeScript)
- New `CODEGRAPH_DIR` environment variable sets the per-project index directory name (default `.codegraph`). This lets one working tree hold two independent indexes — most usefully when you open the same checkout from both **Windows** and **WSL**, which can't safely share a single `.codegraph/`: the background-server lock and the SQLite database are tied to the OS that wrote them, and SQLite locking across the WSL2/Windows filesystem boundary is unreliable. Set `CODEGRAPH_DIR=.codegraph-win` on the Windows side, leave WSL on the default, and each keeps its own index in the same folder without clobbering the other. CodeGraph also skips any sibling `.codegraph-*` directory when indexing and watching, so neither environment trips over the other's data. Thanks @rrtt2323. (#636)

### Fixes

- **opencode on Windows now finds CodeGraph.** The installer wrote opencode's global MCP entry to `%APPDATA%\opencode\`, but opencode reads its config from `~/.config/opencode/` on every platform (honoring `XDG_CONFIG_HOME`), so the entry was invisible to it. Installs now write where opencode actually looks, and `codegraph install` / `codegraph uninstall` both clean a stale CodeGraph entry out of the old `%APPDATA%` location — other servers and comments in that file are left untouched. Thanks @fucknoobhanzo for the report and @WodenJay for the first patch. (#535)
- The `codegraph_search` tool's `kind: "type"` filter — a value its own schema advertises — silently matched nothing; it now correctly finds type aliases. The `codegraph_explore` tool's parameter guidance also no longer suggests running `codegraph_search` first, which contradicted explore's call-it-first design and cost agents an extra round-trip.
- Symbols defined in Svelte and Vue `<script>` blocks were reported one line below where they actually are — a function on line 3 was reported at line 4 — which offset every script-block symbol's location in search, `codegraph_node`, and explore output. Line numbers now match the file exactly. Re-index a project to benefit. (Svelte, Vue)
- Doc comments are now captured for exported, `const`-assigned, and decorated declarations, and the documentation a symbol carries is now clean across every supported language. Previously a comment above `export class X`, `export const fn = () => …`, a plain `const fn = () => …`, or a decorated Python `def`/`class` (`@app.route(...)`, `@dataclass`) was dropped entirely — only comments directly above a plain declaration were kept. CodeGraph now finds the comment through the `export` / `const` / decorator wrapper. Comment-marker cleanup was also rounded out for every language CodeGraph supports: Rust/Swift/Kotlin doc lines (`///`, `//!`), Python/Ruby/shell `#`, Lua/Luau (`--` and `--[[ ]]`), and Pascal (`{ }` and `(* *)`) no longer leave stray markers in the stored text — validated end-to-end across all 19 code languages plus Svelte/Vue `<script>` blocks. (#780). Thanks @caleb-kaiser.
- Go method calls made through a chained factory function now resolve to the correct type. A call like `New().Method()` used to drop the receiver, so the chained method attached to a same-named method on an unrelated type — or didn't resolve. CodeGraph now captures Go return types (a pointer `*Foo` resolves to `Foo`, and a multi-return `(*Foo, error)` to its first result), infers the chained receiver's type from what the factory function returns, and resolves the method on it — including methods promoted from an embedded struct — creating the edge only when the type or an embedded type genuinely has the method. Existing Go indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Go)
- Scala method calls made through a companion-object factory, a fluent chain, or a case-class `apply` now resolve to the correct type. A call like `Foo.create().bar()` or `Builder(cfg).bar()` used to drop the receiver, so the chained method silently attached to a same-named method on an unrelated type — most often mis-attributing a standard-library `Option` / `Iterator` `.map` / `.flatMap` / `.foreach` onto your own same-named class. CodeGraph now captures Scala return types (a generic `List[Foo]` resolves to its container `List`, a qualified `pkg.Foo` to `Foo`), infers the chained receiver's type from what the inner call returns or constructs, and resolves the method on it — including methods inherited from a trait the type extends — creating the edge only when that type or one of its traits genuinely has the method (so a wrong inference produces no edge instead of a misleading one). Existing Scala indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Scala)
- Rust method calls made through a chained associated function now resolve to the correct type. A call like `Foo::new().bar()` or `Foo::with(cfg).build()` used to drop the receiver, so the chained method silently attached to a same-named method on an unrelated type — or didn't resolve. CodeGraph now captures Rust return types (`-> Self` resolves to the implementing type), infers the chained receiver's type from what the associated function returns, and resolves the method on it — including methods provided by a trait the type implements (via the new `impl Trait for Type` relationships) — creating the edge only when the type or one of its traits genuinely has the method. Existing Rust indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Rust)
- Dart method calls made through a static factory, a factory or named constructor, or a fluent chain now resolve to the correct type. A call like `Foo.create().bar()` used to drop the receiver, so the chained method silently attached to a same-named method on an unrelated type — most often mis-attributing a standard-library `Option` / `Iterator` `.map` / `.where` onto your own same-named class. CodeGraph now indexes Dart **factory and named constructors** (`factory Foo.create()`, `Foo.named()`) as first-class members so calls to them resolve, captures Dart return types (a generic `List<Foo>` resolves to its container `List`), infers the chained receiver's type from what the inner call returns or constructs, and resolves the method on it — including methods inherited from a superclass or mixin — creating the edge only when that type genuinely has the method. Plain construction (`Foo(...)`) is still recorded as instantiation. Existing Dart indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Dart)
- Objective-C methods called through a chained message send now resolve to the correct class. A call like `[[Foo create] doIt]` used to drop the receiver, so `doIt` silently attached to a same-named method on an unrelated class — most often a test helper or stdlib class. CodeGraph now captures Objective-C method return types and infers the chained receiver's type from what the inner message returns. For the ubiquitous `[[X alloc] init]` and singleton (`[[X sharedInstance] …]`) patterns — where the factory returns `instancetype` — the receiver is the class `X` itself, so the chained method resolves on `X` (including methods inherited from a superclass), creating the edge only when the class genuinely has the method. Existing Objective-C indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Objective-C)
- Pascal/Delphi methods called through a chained factory call now resolve to the correct class. A call like `TFoo.GetInstance().DoIt()` used to drop the receiver, so `DoIt` silently attached to a same-named method on an unrelated class. CodeGraph now captures Pascal return types and infers the chained receiver's type from what the factory function returns — resolving to the declared type (including an interface return like `IFoo`), and for a constructor (`TFoo.Create().…`) or a typecast (`TFoo(x).…`) to the class `TFoo` itself, since both yield a `TFoo`. The edge is created only when that type genuinely has the method (so a wrong inference produces no edge). Existing Pascal/Delphi indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Pascal/Delphi)
- Pascal/Delphi **paren-less method calls are now tracked**. Pascal lets a no-argument method or procedure drop its parentheses (`Obj.Free;`, `List.Clear;`, `TFoo.GetInstance.DoIt;`), which previously weren't recorded as calls at all — so callers, impact, and trace missed them. CodeGraph now extracts these, scoped to statement position so a field or property access (which looks identical) is never mistaken for a call. On a real Delphi codebase this added ~1,100 previously-missing call edges with no false positives. Existing Pascal/Delphi indexes should be re-indexed (`codegraph index -f`) to benefit. (Pascal/Delphi)
- Pascal/Delphi calls inside a **standalone procedure or function** (one with no `interface` declaration, defined only in the `implementation` section) are now attributed to that routine instead of the whole file. Previously such a routine had no symbol of its own, so everything it called was lumped under the unit — `codegraph_callers` returned the file, and impact couldn't tell which routine was responsible. These routines are now indexed and their calls attributed correctly. Existing Pascal/Delphi indexes should be re-indexed (`codegraph index -f`) to benefit. (Pascal/Delphi)
- Chained method calls now resolve when the chained method is **inherited from a superclass or declared on an interface/protocol** the receiver's type conforms to — for example a call on a sealed-subclass instance (`Either.Right(x).combine(...)`) that invokes a method defined on its parent type. Previously these chains found no caller edge even though the factory's type was known, so the call was invisible to callers, impact, and trace. CodeGraph now walks the type's supertypes (its `extends` / `implements` relationships) to find the method, creating the edge only when a supertype genuinely declares it (so a wrong inference still produces no edge). This makes Java, Kotlin, and C# factory and fluent chains more complete. Existing indexes should be re-indexed (`codegraph index -f`) to benefit. (#750)
- Swift method calls made through a static factory, fluent chain, or constructor now resolve to the correct class. A call like `Foo.make().draw()` or `Foo().draw()` used to drop the receiver, so the chained method silently attached to a same-named method on an unrelated class — or didn't resolve at all. CodeGraph now captures Swift return types and infers the chained receiver's type from what the inner call returns (or the constructed type), creating the edge only when that class genuinely has the method (so a wrong inference produces no edge instead of a misleading one). Existing Swift indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Swift)
- C# method calls made through a static factory or fluent chain now resolve to the correct class. A call like `Foo.Create().Bar()` or `JObject.Parse(s).Property(...)` used to lose the receiver's type, so the chained method didn't resolve and the call was invisible to callers/impact/trace. CodeGraph now captures C# return types and infers the chained receiver's type from what the inner call returns, creating the edge only when that class genuinely has the method (so a wrong inference produces no edge). Existing C# indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (C#)
- Kotlin method calls made through a companion-object factory or fluent chain now resolve to the correct class. A call like `Foo.getInstance().bar()` or `Config.create(opts).build()` used to drop the receiver entirely, so the chained method silently attached to a same-named method on an unrelated class — or didn't resolve at all — corrupting callers, impact, and trace. CodeGraph now captures Kotlin return types and infers the chained receiver's type from what the inner call returns, creating the edge only when that class genuinely has the method (so a wrong inference produces no edge instead of a misleading one). Existing Kotlin indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Kotlin)
- Java method calls made through a static factory or fluent chain now resolve to the correct class. A call like `Foo.getInstance().bar()` or `Config.create(opts).build()` used to lose the receiver's type, so when two classes had a same-named method the call silently attached to whichever was indexed first — or didn't resolve at all — corrupting callers, impact, and trace. CodeGraph now captures Java return types and infers the chained receiver's type from what the inner call returns, creating the edge only when that class genuinely has the method (so a wrong inference produces no edge instead of a misleading one). Covers factories and fluent builders that take arguments (`hashKeys().arrayListValues()`), including builders that return a nested type. Existing Java indexes should be re-indexed (`codegraph index -f`) to benefit. (#750) (Java)
- PHP: a method called through a chained static factory — `Cls::for($x)->method(...)`, the canonical Laravel per-credential / per-tenant client idiom — now records a caller edge. Previously the receiver type (what `for()` returns) was never recovered, so `codegraph_callers` returned nothing for the method and the call was invisible to `codegraph_impact`. CodeGraph now captures PHP return types — `: self` / `: static` resolve to the declaring class, `: SomeClass` to that class — and resolves the chained method on the factory's result, creating the edge only when that class actually has the method (so a wrong inference produces no edge). Existing PHP indexes should be re-indexed (`codegraph index -f`) to benefit. Thanks @cvanderlinden. (#608) (PHP)
- Search relevance: including the project name in a query (a user naturally writes `MyApp backend routes`) no longer buries the part of the codebase the query is actually about. The project name lexically matches whatever stack embeds it — a `MyAppFrontend/` directory, a `MyAppApp` class — and it was over-weighted two ways: a single PascalCase word was scored once per sub-token (`my` / `app` / `myapp`), so one concept boosted that path several times over; and the name carried full path / disambiguation weight even though it names the whole repo, not any symbol. Now path relevance counts each query word once, and a word matching the project name (derived from `go.mod`, `package.json`, or the repo directory) is dropped from path scoring and from `codegraph_explore`'s type-disambiguation bias — unless it's the only term, so a bare project-name search still works. In a mixed-stack repo, a backend question now surfaces the backend even with the project name in the query. Thanks @MiNuo1. (#720)
- Go: a function called only from inside an anonymous closure — a cobra `RunE: func(…) {…}` handler, a goroutine literal, or a callback closure stored in a package-level `var` — now shows its real caller. Previously the call leaked to the file node, so `codegraph_callers` and `codegraph_impact` reported such a function as having no meaningful caller; the call is now attributed to the enclosing declaration, so editing the function surfaces the closures that use it. Existing Go indexes should be re-indexed (`codegraph index -f`) to benefit. Thanks @Cyclone1070. (#693) (Go)
- Indexing no longer aborts when a `.gitignore` contains non-UTF-8 bytes or an unparseable pattern. A `.gitignore` transparently encrypted in place by corporate DLP / endpoint-security software (a common enterprise scenario) — or one with a stray pattern the matcher can't compile (`\[`, producing "Unterminated character class") — used to crash the entire `sync` / `index` with a screen of garbled bytes and never name the offending file, leaving `Files: 0 / Nodes: 0`. CodeGraph now skips a `.gitignore` that isn't valid UTF-8 text whole, drops only the individual unparseable patterns from a text one, and logs a warning naming the file — indexing continues either way. Thanks @zhanghang-9527. (#682)
- C++ method calls made through a singleton, factory, or chained getter now resolve to the correct class. A call like `Foo::instance().bar()`, `WidgetFactory::create().draw()`, `openSession()->run()`, or the same stored in an `auto` local first, used to lose the receiver's type — so when two classes had a same-named method the call silently attached to whichever was indexed first (or didn't resolve at all), corrupting callers, impact, and trace. CodeGraph now infers the receiver's type from what the inner call returns (capturing C++ return types for the first time) and creates the edge only when that class genuinely has the method, so a wrong guess produces no edge instead of a misleading one. Covers singletons and self-returning accessors, factories that return a different type, free-function factories, `make_unique` / `make_shared` / `new` / direct construction, and single-level member chains. Existing C/C++ indexes should be re-indexed (`codegraph index -f`) to benefit. Thanks @stabey. (#645) (C/C++)
- The shared background server no longer logs a scary-looking `[error] … undefined` line on every session start. Attaching to the shared daemon is normal, healthy behavior, but the informational message was being surfaced by MCP hosts (Claude Code and others) as an error; it's now silent by default — set `CODEGRAPH_MCP_LOG_ATTACH=1` to surface it when debugging daemon attach. Thanks @mturac. (#618)
- On Windows, CodeGraph's background processes no longer pile up without bound and saturate CPU over a long session. When the editor or agent that launched CodeGraph exited, its helper process couldn't tell its parent had gone — Windows reports process lineage differently than macOS and Linux — so the helper kept running, the shared background server never saw the client disconnect, and its idle timer never fired to shut it down. CodeGraph now detects parent-process exit directly on Windows, so helpers and the idle background server wind down promptly, the same as they already did on macOS and Linux. (#692, #576, #680)
- The MCP server now shuts down cleanly when its editor/agent connection drops abruptly, instead of risking an orphaned process that pins a CPU core. Editors talk to a stdio MCP server over a socket; if that socket failed with an error rather than closing cleanly — which can happen when the editor window is reloaded or the launching process is killed — the server didn't treat it as a disconnect and could be left running. CodeGraph now treats any failure of its input stream as a shutdown signal and tears the stream down, so an orphaned server exits promptly. (#799)
- The shared background server has two further safeguards against ever lingering: it now drops a client the moment it detects that client's process is gone (even if the disconnect arrived uncleanly — a force-quit or a dropped connection that never closed the socket), and it won't stay running indefinitely with clients attached but no activity. Together these guarantee it always winds down, on every platform. (#692)
- A session no longer loses CodeGraph when the shared background server is restarted out from under it — for example when your MCP host (opencode and others) stops and restarts the server as you open another session. Previously the affected session's connection died silently and any request in flight at that moment hung; now CodeGraph keeps that session working by serving it locally, so the tools stay available without restarting the session. (#662)
- React Native native→JS events now connect through the common `sendEvent(context, "X", body)` wrapper. Many libraries (react-native-device-info and others) wrap the event emitter behind a helper whose `.emit(eventName, …)` takes a *variable*, so the matcher — which looked for `.emit("literal", …)` — missed it; the literal event name actually lives in the wrapper call. Now a native method that fires `sendEvent(…, "batteryLevelChanged", …)` links to the JS `addListener('batteryLevelChanged', …)` handler, so editing the native emitter surfaces the JS subscriber. (React Native)
- React Native / Expo cross-language bridges are more complete and more precise. An Expo Module method declared with a generic type — Android's `AsyncFunction<Float>("getBatteryLevelAsync")` — is now indexed (the `<Float>` used to defeat the matcher, so every Android Expo method was dropped and a JS call resolved only to the iOS Swift impl). The iOS and Android implementations of the same JS-visible method — both Expo Modules and classic NativeModules (`@ReactMethod` on Android, the matching method on iOS) — are now linked to each other, so a JS call that resolves to one platform still reaches the other and editing either platform's native code surfaces the JS caller. And a `Type.member` static read in native code (e.g. Android's `BatteryManager.EXTRA_LEVEL`) no longer falsely links to a coincidentally same-named class in another language (a web `BatteryManager`) — type references stay within a language family, while genuine cross-language bridges (config→code, JS↔native calls) are unaffected. (React Native, Expo)
- A TypeScript/JavaScript reference or import no longer gets mis-linked to a same-named class in a native language. In a React Native / Expo repo that has both a TypeScript `TestRunner` type and a Kotlin `TestRunner` class, a TS reference to `TestRunner` — or an `import React` sitting next to a Swift `React` — used to resolve onto the native symbol (the component resolver matched any same-named class regardless of language, and import statements weren't language-checked at all). References and imports now stay within their language family, so they land on the right symbol while genuine cross-language bridges (JS↔native calls, config→code) are untouched. A C/C++ `#include "Foo.h"` likewise no longer resolves to a same-named header from another platform (an iOS Objective-C `Foo.h`). (React Native, Expo, TypeScript, C/C++)
- Native includes and Kotlin Multiplatform imports now resolve to the correct file in multi-platform projects. A C/C++ `#include "Foo.h"` now resolves to the header in the including file's own directory first (the C quoted-include rule), so when a module ships a same-named header per platform (a Windows, an Apple, and an Android `Foo.h` side by side) the local one correctly shows its dependents instead of an arbitrary other-platform header looking like the dependency. And a Kotlin Multiplatform `expect` declaration is no longer reported as having no dependents: a `commonMain` import now resolves to the `commonMain` `expect` (matched within the importing source set) rather than being absorbed by one platform's `actual`. (C/C++, Kotlin)
- `codegraph affected` now reports the tests and files that actually depend on your changes. It used to follow only `import` statements — but those never cross file boundaries in CodeGraph's graph — so it returned **no affected tests for any change, in every language**. It now traces the real cross-file usage graph (calls, references, instantiations, and class `extends` / `implements`), so `git diff --name-only | codegraph affected` surfaces the test files that exercise the changed code. Circular-dependency detection, which had the same blind spot, now works too.
- Blast radius, callers, and `codegraph affected` now recognize far more of the dependencies that were already in your code. A symbol now counts as a dependency whether it's called, used only in a type annotation inside a function body (`const items: Foo[] = []`), imported and placed in a registry array or passed as an argument, used as a JSX component, simply re-exported from a barrel (`export { X } from './x'`), or pulled in as a namespace (`import * as ns from '@/x'`) — including through tsconfig path aliases like `@/`. Previously only called, instantiated, or signature-typed symbols created a cross-file link, so a file that used a dependency in any other way could look like it depended on nothing — and the file that defined a widely-used symbol could look like nothing depended on it. The graph still indexes exactly the same symbols; it just connects the ones that were already there. (TypeScript/JavaScript)
- The same completeness fix now applies to **Python**: a name brought in with `from module import X` is recorded as a dependency on that module even when `X` is only stored in a list/dict, passed as an argument, used as a decorator, or re-exported through an `__init__.py`. Previously Python linked only imports that were called or instantiated, so a module consumed purely by value — or only re-exported — looked like nothing depended on it.
- `codegraph_callers` (and the `callers` command) now lists the places a class is **instantiated**, not just where it's imported. Constructing a class — `Foo(...)` in Python, `new Foo()` elsewhere — is calling its constructor, so asking who calls a class now returns the construction sites, and `codegraph_callees` / trace cross the instantiation the same way. Previously a class's instantiation sites were invisible to `callers`, so "what breaks if I change this class?" could come back empty even when the constructor was called from many places. Works on your existing index — no re-index needed. (#774)
- Rust impact and `codegraph affected` now connect far more of the module graph. Struct literals (`Widget { n: 1 }`) are recorded as instantiations; a `use` / `pub use` brings its item into the dependency graph — so a `pub use` re-export hub (a `mod.rs` re-exporting its submodules) depends on the modules it re-exports — resolved by Rust module path (`crate::`/`self::`/`super::`), so a re-export of a common name like `read` links to the right module instead of a same-named symbol elsewhere; and trait dispatch reaches implementations — a struct whose methods cover a trait's is treated as implementing it, and a call through `&dyn Trait` resolves to the concrete method. Previously a Rust type linked only when called or used in a type position, so structs built by literal, modules surfaced only through `pub use`, and trait-only implementations looked like they had no dependents. (#584 for Rust traits)
- Rust cross-module function calls now resolve to the right file. A call to a sibling submodule's function — `users::router()`, the common router-assembly / handler-registration pattern where `mod users;` makes `users` a child of the current module — is now resolved relative to the current module, not only the crate root. Deeper module-path calls (`database::profiles::find()` — the `db.run(|c| …)` data-access shape) now resolve too; these were being discarded before resolution even ran, because the path's leaf function name was never checked. Previously such a call linked to nothing, so a module reached only as `module::path::function()` looked like it had no dependents; a web app wired this way (Axum, Rocket, and similar) now surfaces its handler and data-access modules' real callers. (Rust)
- Rocket route handlers now connect to where they're mounted. A handler registered in a `routes![a::b::handler, …]` or `catchers![…]` macro used to be invisible — the macro body is a raw token tree, so the handler looked like it had no caller (Rocket mounts it at runtime) and its file showed no dependents. The handler paths are now read out of the macro and linked to the `mount`/`register` call, so editing a Rocket handler surfaces its route registration and a routes module is no longer reported as unused. (Rust, Rocket)
- SvelteKit pages now connect to their server `load` functions. SvelteKit wires a `+page.server.js` / `+page.js` `load` (and form `actions`) to the sibling `+page.svelte`'s `data` by file path, with no import between them — so editing a `load` previously showed no impact on the page it feeds. Each page is now linked to the `load`/`actions` in its own route directory (and likewise for `+layout`), so editing a loader surfaces the page that renders its data, and tracing a page reaches its server-side data source. (Svelte, SvelteKit)
- Nuxt nested components are now connected to where they're used. Nuxt auto-imports a component in a subdirectory by a directory-prefixed name — `components/media/Card.vue` is used in templates as `<MediaCard/>` — but it was tracked by its file name (`Card`), so the usage didn't resolve and the component looked unused. PascalCase component tags (`<MediaCard>`, `<NavBar>`) in a `.vue` template are now matched, falling back to the Nuxt directory-prefixed name, so editing a nested component surfaces every page and component that renders it. (Vue, Nuxt)
- Lua and Luau `require` calls now connect to their module files. A dotted module path (`require("telescope.config")` → `telescope/config.lua` or `.../config/init.lua`) and a Roblox/Luau instance-path require (`require(script.Parent.Signal)` → the `Signal` module) now link to the file they load, so editing a module surfaces every file that requires it. Previously requires resolved to nothing, so a Lua/Luau module looked like it had no dependents. (Lua, Luau)
- Shopify OS 2.0 sections now connect to the JSON templates that use them. Modern Shopify themes define templates as JSON (`templates/*.json`, plus section groups `sections/*.json`) that list sections by `type` rather than with a `{% section %}` Liquid tag, so a section used only from a JSON template was reported as having no dependents. Those JSON files are now read and each section `type` is linked to its `sections/<type>.liquid`, so editing a section surfaces the templates that render it. (Liquid, Shopify)
- Delphi form definitions now connect to their code-behind units. A `.dfm` (VCL) or `.fmx` (FireMonkey) form is owned by its same-named `.pas` unit through the `{$R *.dfm}` directive rather than a `uses` clause, so a form file used only as a definition was reported as having no dependents. The unit is now linked to its form, so editing a form surfaces the unit that owns it. (Pascal/Delphi)
- Swift property wrappers and attributes are now connected. A `@Argument` / `@Published` / `@State` / custom `@propertyWrapper` on a property — and attributes on types, methods, and functions (`@objc`, `@MainActor`, …) — now record a dependency on the wrapper/attribute type. Previously these were dropped entirely (Swift attributes parse differently from other languages, and stored properties weren't being inspected), so the wrapper type looked unused and the file using it depended on nothing — a big gap for SwiftUI and argument-parser-style code.
- Swift Fluent relationship models are no longer orphaned. A type referenced only through a property-wrapper *argument* — `@Siblings(through: AcronymCategoryPivot.self, …)`, the many-to-many pivot/join model — now records a dependency on that type. Previously only the wrapper itself (`Siblings`) and the property's declared type were captured, so a pivot model reached solely through the relationship looked like nothing depended on it and editing it surfaced no impact. (Swift, Vapor/Fluent)
- Java annotations are now connected. Annotation definitions (`@interface Foo`) are indexed as types, and every `@Foo` usage on a class, method, or field is recorded as a dependency on it. Previously neither side was captured — annotation usages were dropped (they live inside the declaration's modifiers) and `@interface` types weren't indexed at all — so annotation-driven code (Spring `@GetMapping`, JPA `@Entity`, Gson `@SerializedName`, …) showed the annotation as having no users and the annotated class as not depending on it.
- Kotlin Multiplatform `expect`/`actual` declarations are now connected. A platform implementation — `actual fun`, `actual class`, or an `actual typealias` in a `jvm` / `native` / `js` / `wasm` source set — is linked to the common `expect` declaration it fulfills (including the common case of an `expect class` fulfilled by an `actual typealias`). Previously a caller in common code resolved to the `expect` declaration, so every platform `actual` looked like it had no dependents and editing one showed an empty blast radius; now changing a platform implementation surfaces the common API and everything that uses it. (Kotlin)
- Scala impact and `codegraph affected` now connect the type graph that typeclass-style code is built on. A parameterized supertype (`trait Monoid[A] extends Semigroup[A] with Serializable`) now links to each parent; a type used in a `val`/`def` signature, as a type argument, or as a context bound (`def f[A: Monoid]`) — including the trailing implicit parameter list (`(implicit M: Monoid[A])`) where typeclass instances are passed — now records a dependency; and `new T[...] { … }` counts as an instantiation. Previously Scala linked only plain calls and bare, non-generic supertypes, so a trait extended with type parameters, used as a type, or required as an implicit looked like nothing depended on it — which on a typeclass-heavy codebase (cats, algebra) was most of the graph. (Scala)
- PHP impact and `codegraph affected` now understand namespaces and `use` imports. Classes are tracked by their namespaced name, so the many same-named classes a framework defines (Laravel has 7+ `Factory` interfaces, several `Dispatcher`s, across namespaces) are told apart instead of collapsing into one arbitrary match. A `use App\Contracts\Cache\Factory;` now records a dependency on exactly that class — so a contract or interface that's imported and constructor-injected (the dependency-injection pattern) is no longer reported as having no dependents — and parameter, property, and return type-hints are recorded too. Previously PHP ignored namespaces entirely and linked only calls, `new`, and inheritance. (PHP)
- Objective-C impact and `codegraph affected` are dramatically more complete. Four gaps are fixed: a single-argument message (`[cache storeImage:key]` — the most common call form) now matches its `storeImage:` method instead of dropping the colon; a class-message receiver (`[SDImageCache sharedCache]`, `[[Foo alloc] init]`) now records a dependency on the class, whose `@interface` lives in the header; `#import "Foo.h"` now resolves to the header file, so a header is no longer reported as having no dependents; and class-method message calls now resolve through the receiver type. Together these took typical libraries from a third-to-half of their files showing real dependents to ~90%. (Objective-C)
- A type referenced only through a static member or enum value now records a dependency. Reading an enum value (`MediaKind.video`), a static constant (`Colors.red`, `JsonScope.EMPTY_DOCUMENT`), or a class constant (`Foo::BAR`) now links to the type — previously only method calls and `new` did, so a type or enum used purely *by value* (enum-heavy APIs, constants classes — a very common pattern) looked like nothing depended on it. Applies to Java, C#, Kotlin, Swift, Scala, Dart, PHP, and C++.
- Dart impact and `codegraph affected` now follow mixins and method type annotations. A `with` mixin — Dart's core composition mechanism, which Flutter is built on — now records a dependency, so editing a mixin surfaces every class that mixes it in (the whole `with` clause used to be dropped, and a class declared `with M` alone even lost its real superclass link). And types used in a method's parameters or return value now link to their definition, so a class or enum referenced only as a type — not constructed or called — is no longer reported as having no dependents. (Dart)
- C++ free functions are now indexed under their real name. A function written with a qualified-type parameter (`std::string TableFileName(const std::string& dbname)`) or an `auto … -> std::string` trailing return type was mistakenly named after that type (`string`), so calls to it never resolved, `codegraph_node` couldn't find it by name, and the file defining it looked like nothing depended on it. The function now keeps its real name, so cross-file calls, callers, and blast radius work — a meaningful gain for any namespaced C++ codebase (this is how most free functions in a library look). (C++)
- Ruby impact and `codegraph affected` now follow mixins and `require`s. `include`, `extend`, and `prepend` of a module — Ruby's primary composition mechanism (ActiveSupport concerns, `Comparable`, `Enumerable`) — now record a dependency on that module, so editing a concern surfaces every class that mixes it in; previously these were read as a call to a method named `include`, so a module whose methods are exercised only by application code looked like nothing depended on it. And `require "lib/foo"` / `require_relative "../foo"` now link to the required file, so a file pulled in only by a `require` (config-loaded components, gems that don't autoload) is no longer reported as having no dependents. Together these took a typical gem from ~71% of its files showing real dependents to ~100%. (Ruby)
- C# `record` types are now indexed. `record`, `record class`, and `record struct` declarations (everywhere in modern C# — DTOs, value objects, CQRS messages, MediatR notifications) were previously skipped entirely, so every reference, generic type argument (`IEnumerable<MyRecord>`), and `new MyRecord(...)` pointed at nothing and the file defining a record looked like it had no callers or dependents. (#237)
- C# is now parsed with an up-to-date grammar that understands C# 12 **primary constructors**. A class or struct written as `class OrderService(IRepo repo, [FromKeyedServices("primary")] ICache cache) { … }` is now indexed reliably — previously the constructor parameter list confused the parser and could drop the whole class (and all of its methods) from the index, most often exactly when a parameter carried an attribute, as in the ASP.NET keyed-dependency-injection pattern. The primary-constructor parameters are also recorded as dependencies, so the services a type is constructed with show up in its blast radius and "who depends on this contract" answers. Method return types, base types, and members all continue to resolve, and `#if`-guarded members in multi-targeting code keep parsing correctly. (#237)
- Go interfaces now connect to their implementations. Go has no `implements` keyword — a type satisfies an interface just by having the right methods — so CodeGraph now infers that link: a struct whose methods cover an interface's method set is treated as implementing it, and a call through the interface (`API.Marshal(...)`) reaches every concrete implementation. This means a type used only via an interface (the common plugin/strategy pattern — e.g. JSON-codec or renderer implementations selected at runtime) is no longer reported as having no callers or no dependents, and impact now flows from an interface method to the implementations behind it. (#584)
- Go now records cross-package struct creation. A composite literal like `render.XML{...}` or `pkga.Widget{...}` — including ones registered in a package-level `var registry = map[string]R{...}` — now links to the package that defines the type. Cross-package function calls and type references already resolved; this closes struct instantiation, so a package whose types are only *constructed* elsewhere (a common pattern for interface implementations) is no longer reported as having no dependents. Go type conversions such as `(*Wrapped)(x)` now link to the converted-to type as well.
- Python now follows whole-module imports — `from . import certs` then `certs.where()`, or `from pkg import sub` then `sub.run()`. Calls and attribute access through an imported submodule now resolve to that submodule, and importing a module is recorded as a dependency on it even when the member you use is itself re-exported from a third-party package. This also fixed Python relative-import path resolution generally (`from .sub.mod import x`), so `codegraph affected` and impact see the real module graph of a package.
- Python now also links a whole-module **absolute** import (`import conduit.apps.signals`) to that module's file, not just `from x import y`. A module imported by its dotted path — common in package setup and side-effect imports — is no longer reported as having no dependents. Standard-library imports (`import os`) correctly create no edge. (Python)
- Python `from package import submodule` now links to that submodule's file, resolved through the import's package so it lands on the right one when same-named modules exist in sibling packages (the FastAPI / Django router-aggregator pattern: `from app.api.routes import authentication` with an unrelated `authentication.py` elsewhere). So a route/handler module pulled in only by an aggregator is no longer reported as having no dependents. (Python)
- Python now records the actual call edge for a function invoked through an imported module — `from pkg import module` (or `import pkg.module`) followed by `module.func()`, a common testing and namespacing pattern. Previously only the module-level dependency was tracked, so `codegraph_callers`, `codegraph_callees`, and impact on the target function came back empty even though the import itself resolved. (#578) (Python)
- Django `include('app.urls')` now records a dependency from the project URLconf onto the included app's `urls.py`, so an app's routes module is no longer reported as having no dependents and editing it surfaces the project that mounts it. (Django)
- A chained method call (`builder.Services.AddCoreServices(...)`) now resolves to its definition. Previously only a single-segment receiver (`obj.method()`) resolved, so a call through a property/member chain — very common for C# extension methods like ASP.NET dependency-injection registration (`AddCoreServices`/`AddWebServices`) and Guard clauses — found no definition. (C#, and any language with chained calls)
- A renamed default import (`import articlesController from './article.controller'` where the module does `export default router`) now records a dependency on the imported module. Previously only named imports linked, so a module consumed only through a default import — the standard Express/NestJS route-controller pattern — looked like nothing depended on it. External packages (`import React from 'react'`) still create no edge. (TypeScript/JavaScript)
- The background file watcher no longer exhausts your machine's file-descriptor budget. On macOS it previously kept **one open file handle per watched file**, so on a large project the running MCP server could pile up tens of thousands of handles and blow past the system-wide limit — at which point *unrelated* apps (your shell, editor, Docker, browser) started failing with "too many open files" until the codegraph process was killed. The watcher now uses a single recursive watch on macOS and Windows, and bounded per-directory watches on Linux, so its cost stays flat no matter how large the project is. (#644, #496, #555, #628, #579)
- Indexing a project with very symbol-dense files (tens of thousands of functions or methods in a single file) no longer runs out of memory. The step that links dynamic call relationships used to load every function and method into memory at once, which could exhaust the heap and abort indexing with "JavaScript heap out of memory" on large or generated codebases; it now streams them, so memory stays flat no matter how many symbols the project has. (#610)
- Indexing a very large repository no longer aborts during its first sync with a "too many SQL variables" error. (#540)
- Files under directories with non-ASCII names (for example CJK characters) are no longer silently skipped during indexing. (#541)
- The `.codegraph/` index folder no longer clutters `git status`: its generated ignore file now excludes everything in the folder except itself, so the database, `daemon.pid`, sockets, and logs stop showing up as untracked changes. (#492, #484)
- Projects initialized by an older version now get that fix automatically: a `.codegraph/.gitignore` written before this change — which listed only the database, cache, and logs and so let the daemon's `daemon.pid` get committed — is upgraded in place the next time you run any CodeGraph command. A `.gitignore` you've customized yourself is left untouched. (#788)
- SAP HANA `.xsjs` / `.xsjslib` files are now indexed as JavaScript. (#556)
- TypeScript `.mts` and `.cts` module files are now indexed instead of being skipped. (#366)
- JavaScript modules that wrap their code in an anonymous function — AMD/RequireJS, NetSuite SuiteScript, IIFE bundles — now have their inner functions and calls indexed, instead of the file coming up nearly empty. (#528)
- Go methods declared on generic types (e.g. `func (s *Stack[T]) Push(...)`) are now correctly attached to their type, so callers, callees, and impact include them. (#583)
- Go methods now attach to their receiver type even when declared in a different file from the `type` itself — the idiomatic split where `type User struct{…}` lives in one file and `func (u *User) Save()` in another. Previously a cross-file method was orphaned from its struct, so the type's member list, callers/callees, and impact missed it; as a knock-on, a struct whose interface-satisfying methods are spread across files now also links to the interfaces it implements. (#583)
- Asking what a symbol impacts no longer drags in every unrelated sibling method of its class — impact now follows real dependencies instead of the structural "contains" relationship, keeping the result focused on what actually depends on the symbol. (#536)
- CodeGraph's MCP server now answers an agent's `resources/list` and `prompts/list` probes with an empty list instead of an error, clearing the `-32601` messages some clients (opencode, Codex) logged on connect. (#621)
- Svelte and Vue components used through a barrel file — `export { default as Button } from './Button.svelte'` re-exported from an `index.ts` and imported elsewhere — are no longer falsely reported as having **0 callers**. CodeGraph now follows the default re-export all the way to the component and resolves the imports that `.svelte` / `.vue` files themselves use, so `codegraph_callers` and `codegraph_impact` see every place a component is used. This also covers components imported from another package in a workspace/monorepo (`@scope/ui/widgets`) and bare directory imports (`import { x } from './'`). Previously a live component consumed only through a barrel looked like dead code. Thanks @nakisen. (#629)
- Components used in a Vue Single-File Component's `<template>` — `<MyButton />`, or the kebab-case `<my-button />` — are now indexed as usages, so `codegraph_callers` and `codegraph_impact` include components that appear only in another component's markup (including through a barrel re-export). Previously only a Vue component's `<script>` block was analyzed, so template-only usages were invisible. (#629)
- PHP: `include` / `require` / `include_once` / `require_once` of a static path now create a file→file dependency edge, so `codegraph_callers` and `codegraph_impact` follow includes in procedural / script-style PHP codebases — previously only namespace `use` statements became dependency edges. Dynamic includes (`include $var`, `require __DIR__ . '/x'`) are skipped. Thanks @atahan150 (#660).

## [0.9.9] - 2026-06-02

### New Features

- `codegraph_explore` is now the primary tool, and one call is usually all an agent needs: it returns the verbatim source of the symbols relevant to your question (a plain question works as the query — you no longer need exact symbol names), grouped by file and Read-equivalent, so the agent answers without falling back to read/grep. The narrower `codegraph_context` and `codegraph_trace` tools were removed in favor of it — explore already surfaces the call flow among the symbols you name (the job trace did), so there's one obvious tool to reach for instead of three.
- `codegraph_explore` now includes a compact "Blast radius" for the symbols you're looking at — who depends on each (just the locations, not their source) and which test files cover it — so before editing, the agent can see what else to update and which tests to run, without a separate impact lookup. Symbols nothing depends on are skipped, so it stays short.
- Functions defined inside a store or handler object — the actions in a Zustand `create((set, get) => ({ … }))` store, and the same shape in Redux, Pinia, MobX, or any exported handler/route map — are now indexed as real symbols. Previously they existed only as object properties, so looking one up by name or asking who calls it returned "not found" and the agent had to read the whole store file to follow the flow; now `codegraph_node`, `codegraph_callers`, and `codegraph_explore` resolve them directly — including calls made through `useStore.getState().fetchUser()` or a destructured `const { fetchUser } = useStore.getState()`.
- `codegraph_explore` now surfaces the *right* definition when a method name is overloaded across types. Asking about, say, `DataRequest`'s `task` and `validate` used to return a same-named method from an unrelated file (or an abstract base stub) and bury the one you meant; explore now recognizes the type you named in the query and leads with that type's own overloads, in full.

### Fixes

- Search ranking no longer lets a common word in your request hijack the results: asking about, say, a "flat object" screen used to surface an unrelated constant that merely happened to be named the same, because the exact-name match outweighed everything else. Ranking now weighs how well each result is corroborated by the rest of your request, so the symbols you actually meant come first (this improves `codegraph_explore`'s results).
- `codegraph_node` now returns *every* definition when a name is ambiguous — an overloaded method, or the same method name on different types — instead of returning one (sometimes the wrong one) with a note listing the rest. Asking for such a symbol now hands back all of the matching definitions with their source in a single call, so the agent stops having to read the file by hand to find the specific overload it wanted (common in Swift, Go, Java, and C#). For a heavily-overloaded name (a `poll`/`validate` with dozens of definitions), pass `file` (and/or `line`) — e.g. the `file:line` shown in a trail — to get that exact definition's body. Large overload sets show the most relevant ones in full and list the remainder by location.
- `codegraph_explore` never returns half a method anymore: when output runs up against its size budget it drops whole methods or whole files (and lists what it dropped, so you can ask for them in another call) instead of cutting off a method body partway. A truncated method was the one case that still sent the agent to read the file for the rest — so the source explore returns is now always complete and usable as-is.

## [0.9.8] - 2026-06-01

### New Features

- `codegraph init` now builds the initial index by default — you no longer need the `-i`/`--index` flag (it's still accepted, so existing commands and scripts keep working). (#483)
- Go: Gin middleware chains now connect end-to-end in `codegraph_trace` and `codegraph_explore` — following a request reaches the middleware and route handlers registered via `.Use()` / `.GET()` instead of dead-ending where the framework dispatches the chain dynamically.
- `codegraph_explore` now sizes its response to the *answer* instead of the file count: it shows the mechanism and the exact methods you asked about in full — even when they're buried deep in a large file — while collapsing the redundant interchangeable implementations of an interface (an HTTP interceptor chain, a query-compiler family) down to signatures. Fewer tokens for a more complete answer, so on the flows that used to occasionally cost more than plain grep/read it's now clearly cheaper — and the win holds across small, medium, and large codebases. Distinct, non-interchangeable code is shown in full as before. Disable with `CODEGRAPH_ADAPTIVE_EXPLORE=0`.
- Swift deferred-validation flows (and similar "handler array" patterns) now connect end-to-end in `codegraph_trace` and `codegraph_explore` — following a request's lifecycle reaches the validators registered with `.validate { … }` instead of dead-ending where the framework runs them by iterating a stored list of closures. Any pattern where closures are appended to a collection and later invoked by looping over it is now traced.
- `codegraph_explore` now spells out the dynamic-dispatch relationships of the symbols you ask about — e.g. "the closures registered here are run by `didCompleteTask`" — so the indirect hops you'd otherwise grep to reconstruct are listed alongside the call flow.
- `codegraph_explore` answers multi-phase questions that span a large "god file" far more completely. For a flow like "build, send, and validate a request" — where one big file holds the build chain and the validate logic lives in others — it now keeps every method *on the flow path* in full, collapses the file's off-path methods to one-line signatures, and guarantees each phase's defining file is shown (instead of truncating at a fixed size and dropping whichever phase came last, which sent you to read it by hand). Incidental files that merely name-drop the flow are still trimmed, so the response stays focused on the code that answers the question.
- CodeGraph is usable as an embedded library again: `require("@colbymchenry/codegraph")` and `import` now resolve the programmatic API — the `CodeGraph` class plus building blocks like `DatabaseConnection`, `QueryBuilder`, `initGrammars`, and `FileLock` — so you can drive the graph directly from your own app (for example an Electron process) instead of only through the CLI or MCP server. Embedding runs on your own runtime, so it needs Node 22.5+ for the built-in SQLite. (#354)

### Fixes

- `codegraph_trace` now resolves an overloaded symbol name to its real implementation instead of an empty protocol/delegate stub. Tracing a flow through a heavily-overloaded API (common in Swift, Java, C#, and Go) could land on an unrelated no-op method that happened to share the name and report "no path"; it now picks the substantive definition the flow actually runs through.
- CodeGraph's MCP server now answers an agent's opening handshake the instant it launches instead of blocking while the index loads, so a fresh session's very first tool call no longer occasionally races a server that's still warming up and falls back to grep/read. The first question in a new session now reliably goes through CodeGraph.
- Indexing a project that contains only config-style files (YAML, Twig, or `.properties`) no longer misleadingly reports "No files found to index" — these files are tracked at the file level and are now counted as indexed. Thanks @luojiyin1987 (#357).

## [0.9.7] - 2026-05-28

### New Features

- Go: gRPC interface stubs now connect to their hand-written implementation, so callers, callees, impact, and trace land on the real method instead of an empty generated stub.
- Generated files (protobuf, gRPC stubs, mocks, build output) now rank last in search, trace, and explore, so results land on your real implementation instead of an auto-generated placeholder.
- When `codegraph_trace` can't find a static path (a dynamic-dispatch break), it now inlines both endpoints' source, callers, and callees in one response, so the agent gets the full picture without a flurry of follow-up calls.
- Trace now picks the right endpoints in large multi-module repos by preferring symbols that share a directory, instead of grabbing an arbitrary same-named symbol from an unrelated module.
- Test files are now deprioritized in `codegraph_explore` (Go, Ruby, JS/TS, Java/Kotlin/Scala), so the explore budget goes to your real implementation source.
- Small projects (under ~500 files) now resolve flow questions in fewer MCP calls, with a leaner tool surface and tuned context and explore output sized for the project.
- `codegraph_context` now auto-traces flow questions like "how does X reach Y" or "trace the path from A to B", splicing the trace into the response so you don't need a separate `codegraph_trace` call.
- `codegraph_context` now inlines a URL-to-handler routing table and the source of your main routes file for routing questions on small projects, so you don't have to go read `routes.rb` or `web.php` yourself.
- `codegraph_context` search now boosts results in the directory of a project's core framework file, so a small same-named extension file no longer outranks the actual framework core.
- Interface-to-implementation linking now works for C#, TypeScript, JavaScript, Swift, and Scala (previously Java/Kotlin only), so investigating an interface method surfaces its concrete implementations.
- MCP tool descriptions are now shorter, trimming per-session overhead while keeping the steering guidance.
- Java and Kotlin imports now resolve by fully-qualified name, so same-name classes in different packages are told apart correctly in multi-module Spring and Android codebases, including across the Java/Kotlin interop boundary.
- Java and C# anonymous classes (`new T() { ... }`) and their overridden methods are now indexed as real class nodes, so an agent sees those hidden overrides in its trail without a Read.
- The installer no longer writes a duplicate `## CodeGraph` instructions block into your agent's instructions file (`CLAUDE.md`, `AGENTS.md`, `GEMINI.md`, Cursor's `.cursor/rules/codegraph.mdc`, or Kiro's steering doc) — the MCP server is now the single source of truth, and re-running `codegraph install` or `codegraph uninstall` strips a block a previous version left behind (#529). If you added your own notes inside the `CODEGRAPH_START`/`CODEGRAPH_END` markers, move them outside the markers first, since the whole marked block is removed.

### Fixes

- MCP tools no longer return results for files that were deleted while no server was running — the first query of a session now waits for the catch-up sync, so you get the correct index instead of stale rows.
- Windows: black console windows no longer flash on every file save or MCP reconnect (#485, #510, #530).
- `codegraph index` and `init -i` now report the true edge count in their summary, instead of undercounting by missing resolution and synthesizer edges.

## [0.9.6] - 2026-05-27

### New Features

- Enterprise Spring and MyBatis flows now trace end-to-end: MyBatis XML mappers are indexed and linked to their Java mapper interfaces, Spring `@Value` and `@ConfigurationProperties` references resolve to the matching keys in your `application.yml`/`.properties` config (including relaxed kebab/camel/snake binding), and field-injected concrete beans like `this.field.method()` resolve through to their implementation (#389).
- Gemini CLI (and the rebranded Antigravity CLI) plus the Antigravity IDE are now supported by `codegraph install`, detected and configured out of the box with sibling settings and MCP servers preserved across re-installs (#399).
- Kiro (CLI and IDE) is now supported by `codegraph install` on macOS, Linux, and Windows, with its own steering file so it loads CodeGraph guidance naturally (#385).

### Fixes

- C/C++: bare `#include "header.h"` directives now connect to the real header file instead of a phantom import, so includes show up as true file-to-file edges; system and stdlib headers are filtered out so they don't false-resolve (#453).
- Java/Kotlin: imports now disambiguate same-name classes across modules using the fully-qualified import path, so callers, callees, and trace land on the right class in multi-module projects instead of guessing by file proximity (#314).
- TypeScript: `type` aliases with object shapes (including function-typed members and intersection types) now surface their members in the graph, so a call like `handle.stop()` resolves to the alias member instead of an unrelated look-alike class in a sibling directory (#359).
- C#: parameter, return, property, and field types now produce reference edges, so callers and callees on a DTO or service type return real results instead of nothing (#381).
- Go: cross-package qualified calls like `pkg.Func()` now resolve to the right package by reading your `go.mod`, so callers, callees, impact, and trace return complete results on Go monorepos instead of almost nothing (#388).
- `codegraph_files` now returns the whole project when an agent passes a root-ish path like `/`, `.`, `./`, `""`, or a Windows-style `\`, and subdirectory filters like `/src`, `./src`, and `src\components` all resolve correctly instead of returning "No files found" (#426).
- The file watcher no longer marks edited files as fresh when another process holds the index lock, so the per-file staleness signal stays accurate until the edit is actually indexed (#449).
- TypeScript/JavaScript: calls inside top-level variable initializers (`const token = getToken()`) and inside inline object-literal methods are no longer dropped, so they show up in callers as expected, including in Vue single-file components (#425).
- Watch sync no longer aborts with a `FOREIGN KEY constraint failed` error in a long-running daemon; a stale lookup now drops a single edge instead of failing the whole sync (#455).
- Hermes: `codegraph install --target hermes` no longer corrupts `~/.hermes/config.yaml`, correctly handling PyYAML's block-style lists and re-installing cleanly even on an already-corrupted file (#456).
- NestJS: route prefixes from `RouterModule.register([...])` (including nested `children`) now propagate to controller routes, so a route shows up at its full path like `GET /admin/users` instead of `GET /` (#459).
- C++: callers now resolve through typed member pointers such as `m_alg->Processing()`, including out-of-line method definitions and the common case of two classes sharing a method name (#445, #454).

## [0.9.5] - 2026-05-25

### New Features

- Running multiple AI agents in the same project no longer multiplies the cost: two Claude Code windows, a worktree agent, or parallel sub-agents now share one background daemon per project with a single file watcher, SQLite connection, and tree-sitter warm-up instead of N independent copies (#411).
- The daemon runs detached so it outlives any single session, meaning closing one editor or terminal never severs the others; it lingers briefly after the last client disconnects so back-to-back sessions skip the startup cost, then exits and cleans up after itself. Tune the idle wait with `CODEGRAPH_DAEMON_IDLE_TIMEOUT_MS` (default five minutes).
- Set `CODEGRAPH_NO_DAEMON=1` to opt out and get one independent server per client, handy for debugging or sandboxes that disallow local sockets; the daemon is also version-pinned, so upgrading CodeGraph never mixes versions over the connection.
- CodeGraph responses now tell the agent which files are pending re-index: when the watcher has seen edits since the last sync, tool responses add a warning banner naming the stale files and their state so the agent reads just those directly while trusting the rest, with zero cost when nothing is pending (#403).
- `CODEGRAPH_WATCH_DEBOUNCE_MS` lets you tune the file-watcher quiet window (default 2000ms) for workspaces with bursty writes like format-on-save chains or large generated outputs, without touching your agent's command line (#403).
- Objective-C indexing: `.m`, `.mm`, and content-sniffed `.h` files now parse with full structural extraction, including full multi-part selectors, properties, imports, and superclass/protocol relationships, so trace, callers, and callees work across iOS codebases (#165).
- Mixed iOS, React Native, and Expo projects now trace end-to-end across language boundaries: Swift to Objective-C auto-bridging, the React Native legacy bridge and TurboModules, native-to-JS event channels, Expo Modules, and Fabric/Codegen view components are all bridged so flows connect through gaps that static parsing alone can't follow (#401).

### Fixes

- TypeScript: types used only in an interface's property or method signatures now produce references edges, so impact and callers on a type include every consumer that imports it just for an interface shape (#432).
- Git worktrees no longer silently borrow another tree's index; running CodeGraph from a worktree nested inside the main checkout used to return the wrong branch's code with no warning, and now both the status command and every read tool call out the conflict and point you to `codegraph init -i` in the worktree (#155).
- The file watcher no longer exhausts the OS file-watch budget on large repos: it now excludes the same directories the indexer ignores (defaults plus your `.gitignore`) before registering watches, so CodeGraph can run alongside your editor or dev server without hitting the per-user watch ceiling (#276).
- The index now stays in sync after `git pull`, branch switches, and edits made outside your editor; change detection is filesystem-based instead of relying on `git status`, so pulled or checked-out code is picked up without a full re-index.
- The MCP server now catches up on connect, reconciling anything that changed while it wasn't running so your first query reflects the current code instead of a stale snapshot.
- Dependency, build, and cache directories like `node_modules`, `vendor`, `dist`, `build`, `target`, `.venv`, `__pycache__`, `Pods`, and `.next` are now excluded by default, so context and search reflect your code instead of third-party noise even in a project with no `.gitignore`; add a `.gitignore` negation to index one anyway (#407).

## [0.9.4] - 2026-05-24

### New Features

- Request-to-handler flows now trace end-to-end across many web stacks, with new or improved route resolution for Express, Rails, Spring (Java and Kotlin), Django/DRF, Laravel, Flask, FastAPI, Gin, chi, ASP.NET, Drupal, Axum, actix, Vapor, Play, Vue/Nuxt, Svelte/SvelteKit, and React Router.
- `codegraph_trace`, `codegraph_callees`, and `codegraph_explore` now follow flows that have no static call edge — callback and observer registration, EventEmitter, React re-renders and JSX children, Flutter `setState` to `build`, C++ virtual overrides, and Java/Kotlin interface-to-implementation dispatch (like Spring's `@Autowired` service calls) — and each bridged hop is labeled inline in trace with where it was wired up.
- `codegraph_trace` now returns a self-contained flow dossier: every hop shows its full body inline plus the destination's own outgoing calls, so a single trace usually answers a "how does X reach Y" question without a follow-up explore, node, or Read.
- `codegraph_explore` now leads with the execution flow when your query names the symbols of a flow, finding the call path among those symbols (including across dynamic-dispatch hops) so you get a trace-quality answer without switching tools.
- `codegraph_node` and `codegraph_trace` now emit line-numbered source (matching `codegraph_explore` and Read), so you can cite or edit exact lines without re-reading the file just to recover line numbers.
- New `CODEGRAPH_MCP_TOOLS` environment variable lets you expose only a chosen subset of codegraph tools over MCP (e.g. `trace,search,node,context`) without editing your client's MCP config; unset exposes all of them.
- Release archives now ship with a `SHA256SUMS` file, and the npm launcher verifies the bundle it downloads against it, aborting on a mismatch (releases published before this change skip verification rather than failing).

### Fixes

- Several static-extraction and resolution correctness fixes underpin the routing work above: C++ inheritance edges that were previously missing, Dart methods that were extracted signature-only, Python handlers named `index`/`get`/`update` that were being silently dropped, and an explore output-budget issue that under-returned source on repos with very large files.
- `codegraph serve --mcp` no longer keeps running after its parent agent is force-killed (OOM, `kill -9`, or container teardown) on Linux, where it used to hold inotify watches, file descriptors, and the SQLite WAL indefinitely; the server now shuts down as soon as its parent process changes, tunable via `CODEGRAPH_PPID_POLL_MS` (#277).
- Installing `@colbymchenry/codegraph` through a registry mirror that hadn't yet mirrored the matching per-platform package no longer fails with `no prebuilt bundle for <platform>`; the launcher now downloads the bundle from GitHub Releases and caches it, with `CODEGRAPH_NO_DOWNLOAD=1` to disable the fallback and `CODEGRAPH_DOWNLOAD_BASE` to point it at your own mirror (#303).
- `install.sh` no longer fails with `403` / "could not resolve latest version" on shared or cloud hosts that exhaust GitHub's unauthenticated API rate limit; it now resolves the version through the unthrottled releases redirect, and `CODEGRAPH_VERSION` accepts a bare version like `0.9.4` as well as `v0.9.4` (#325).

## [0.9.3] - 2026-05-22

### New Features

- New `codegraph uninstall` command cleanly removes CodeGraph from every agent it's configured on — Claude Code, Cursor, Codex CLI, opencode, and Hermes Agent — in one step, asking whether to clean up your global or this project's local config and reporting exactly which agents it touched; it accepts `--location`, `--target`, and `--yes` for scripted or non-interactive use, removes only what `codegraph install` wrote, and leaves your `.codegraph/` index alone (#313).

### Fixes

- Indexing a large multi-language project no longer aborts partway through with a `Fatal process out of memory: Zone` crash on Node.js 22 and 24, even with plenty of RAM free — CodeGraph now launches with a V8 flag that keeps grammar compilation off the optimizing tier, and any launch path that doesn't get the flag directly re-execs once with it automatically (#298, #293). Node 25 stays blocked for now, since its variant of this bug isn't fixed by the same flag.
- Uninstalling from Cursor now deletes the leftover `.cursor/rules/codegraph.mdc` file outright instead of leaving an orphaned, empty rule behind, while keeping any content you added outside CodeGraph's markers.

## [0.9.2] - 2026-05-21

### Breaking Changes

- CodeGraph no longer has a config file: `.codegraph/config.json` and the entire config surface are gone, and the library API for it (the config type, the `config` option on `init()`, and the get/update config exports) has been removed — existing config files are now ignored, and `.gitignore` is the single source of truth for what gets indexed. The `.codegraphignore` marker is also no longer supported; use `.gitignore` instead.

### New Features

- `codegraph install` now supports Hermes Agent (Nous Research), wiring up the CodeGraph MCP server so Hermes can drive the knowledge graph like the other agents.
- Drupal projects (8/9/10/11) are now detected and indexed with framework smarts: routes from `*.routing.yml` link to their controller, form, or entity-handler, and hook implementations across modules are connected to their canonical hook name, so asking for callers of a hook returns every implementation (#268).
- Indexing is now zero-config and honors your `.gitignore` everywhere — in git repos via git, and in non-git projects by reading `.gitignore` files directly — so to keep something out of the graph you just add it to `.gitignore`. Behavior change: committed files that aren't gitignored are now indexed even under `vendor/`, `Pods/`, or a committed `dist/`; add a `.gitignore` negation to exclude them (#283).

### Fixes

- Windows: installing globally and then running any `codegraph` command no longer fails — the launcher now invokes the bundled runtime directly instead of a `.cmd` file that modern Node refuses to spawn, so `codegraph` works regardless of your Node version (#289).

### Security

- The temp-dir marker written on each `codegraph_context` call is now opened safely so it can't follow a symlink, closing a hole where another local user on a shared machine could redirect that write onto a file you can write (#280).

## [0.9.1] - 2026-05-21

### Fixes

- The standalone installers (`curl … | sh` and `irm … | iex`) no longer fail to launch on a machine that has no Node installed.
- Installing with `npm i -g` on Linux x64 now finds its bundle, after the 0.9.0 release silently shipped without the linux-x64 package; the release pipeline now verifies every package reached the npm registry so a release can't pass green-but-broken again.

## [0.9.0] - 2026-05-21

CodeGraph now ships its own self-contained runtime, so it installs on any Node version — or none at all — with no native build step, and the old intermittent "database is locked" errors are gone for good.

### New Features

- One-line standalone installers that need no Node.js: `install.sh` on macOS and Linux, and `install.ps1` on Windows fetch the self-contained bundle and put `codegraph` on your PATH (you can still use `npm`/`npx` on any Node version too).
- CodeGraph now uses real SQLite with full WAL and FTS5 built into its bundled runtime, which fixes the concurrent-read "database is locked" errors at the root, removes the native build step entirely, and runs faster for anyone who had been stuck on the old WASM fallback (#238).
- Lua: CodeGraph now indexes `.lua` projects (Neovim plugins, Kong, OpenResty, game code), surfacing functions, table methods, local variables, `require(...)` imports, and the call edges between them.
- Luau: CodeGraph now indexes `.luau`, Roblox's typed superset of Lua, adding type and `export type` aliases, typed function signatures, generics, and Roblox instance-path requires on top of everything Lua extracts (#232).
- `codegraph status` now reports the effective journal mode, so a "database is locked" report is easy to triage at a glance.

### Fixes

- Re-running `codegraph install` now strips the broken auto-sync hooks that pre-0.8 versions wrote into Claude Code's settings, which had been causing a "Stop hook error: unknown command 'sync-if-dirty'" on every turn. The cleanup is surgical and leaves unrelated hooks untouched. Re-run `codegraph install` once on an affected machine to clear the error.

## [0.8.0] - 2026-05-20

### Breaking Changes

- The minimum supported Node.js version is now 20 (Node 18 is end-of-life); Node 22 LTS and Node 24 get the fast native backend out of the box, other Node versions still run via the slower WASM fallback, and Node 25+ remains blocked (#81). If you're on an older Node, upgrade to 20 or newer.

### New Features

- NestJS: CodeGraph now recognizes NestJS projects and surfaces the route that binds each handler across HTTP controllers, GraphQL resolvers, microservice handlers, and WebSocket gateways, detected automatically from any `@nestjs/*` dependency (#220).
- `codegraph_explore` source now includes line numbers, so an agent can cite `file:line` straight from the result instead of reopening the file to find a line number; set `CODEGRAPH_EXPLORE_LINENUMS=0` to disable.
- On WSL2 `/mnt/*` drives, where the live file watcher is too slow and could break MCP startup, CodeGraph now skips the watcher and offers to keep the index fresh with git hooks instead; new `CODEGRAPH_NO_WATCH=1` (or `serve --mcp --no-watch`) forces the watcher off anywhere, and `CODEGRAPH_FORCE_WATCH=1` overrides the WSL auto-detect when your setup is actually fast.
- CodeGraph now guides agents to answer "how does X work" and architecture questions directly with a couple of codegraph calls instead of delegating to a file-reading sub-agent or a grep-and-read loop, which gives faster, cheaper, `file:line`-cited answers on medium and large repos.
- `codegraph_node` with code on a class, interface, struct, or enum now returns a compact member outline (fields plus method signatures with line numbers) instead of the entire class body; functions and methods still return their full source.
- `codegraph_explore` output now scales with project size, so small projects get tighter responses than your native grep-and-read flow would produce while large codebases keep their fuller budget, and a per-file cap stops a single dense file from collapsing into a whole-file dump (#185). Thanks @essopsp.
- Search ranking now correctly de-prioritizes CamelCase test files (`FooTest.kt`, `BarTests.swift`, `BazSpec.scala`, `QuxTestCase.cs`) and test source-set directories in Kotlin, Swift, Scala, and C#, so real implementations no longer get outranked by tests.

### Fixes

- `codegraph_explore` output is now hard-capped to its size budget, so an oversized response no longer overruns the cap and sits in the agent's context to be re-read every turn.
- Newly created untracked files are no longer reported as pending forever and re-indexed from scratch on every `codegraph sync`; CodeGraph now hash-compares them against the index the same way it does tracked files (#206). Thanks @15290391025.
- `codegraph init -i` now finds source inside nested, independent git repositories that aren't submodules (common in CMake super-repo layouts), instead of reporting "No files found to index" (#193). Thanks @timxx.
- On Node 24, indexing no longer silently drops to the slower fallback backend with a warning that couldn't be cleared; a fresh install on Node 22 or 24 now gets the fast native backend with no compiler, and `codegraph status` should report it (#203). Thanks @Finndersen.
- MCP tools no longer fail with "CodeGraph not initialized" when the index actually exists; when the client doesn't report a workspace root, the server now asks for it via the standard MCP `roots/list` request before falling back, and the error message is actionable when a project still can't be resolved (#196). Thanks @zhangyu1197.
- The MCP server no longer hangs on startup under WSL2 when the project lives on an NTFS `/mnt/*` mount, so the codegraph tools actually appear; CodeGraph auto-skips the watcher there with manual and git-hook sync fallbacks (#199). Thanks @mengfanbo123.
- Claude Code project-local installs now write the MCP server to `.mcp.json` (the file Claude Code actually reads for project-scoped servers) instead of a file it ignores, and re-running `codegraph install` migrates an affected project automatically (#207). Thanks @Jhsmit.
- Source-omission markers in `codegraph_explore` and `codegraph_context` output are now language-neutral instead of C-style comments, so they no longer look wrong inside Python, Ruby, and other non-C source blocks.

## [0.7.10] - 2026-05-19

### Fixes

- CodeGraph tools now reliably appear in your client on slow filesystems (Docker Desktop VirtioFS on macOS, WSL2), where the startup handshake could previously time out and leave the process running with no tools visible (#172). Thanks @sashanclrp and @sgrimm.
- On Windows PowerShell and cmd.exe, terminal output during `codegraph index` and `codegraph sync` no longer turns into garbled characters; CodeGraph now uses plain ASCII glyphs by default on Windows, with `CODEGRAPH_UNICODE=1` to opt back into the Unicode glyphs or `CODEGRAPH_ASCII=1` to force ASCII on any platform (#168). Thanks @starkleek and @Bortlesboat.
- Module-qualified symbol lookups now resolve in the codegraph tools, so you can pass names like `module::symbol` (Rust, C++, Ruby), `Module.symbol` (TypeScript, JavaScript, Python), or `module/symbol`, including multi-level paths and Rust prefixes like `crate`, `super`, and `self` (#173). Thanks @joselhurtado.

## [0.7.9] - 2026-05-17

### New Features

- opencode: the installer now writes an `AGENTS.md` file with CodeGraph usage guidance, so opencode reaches for the `codegraph_*` tools instead of falling back to its native search.
- opencode: your comments and formatting in `opencode.jsonc` now survive install, re-install, and uninstall, because the installer makes surgical edits instead of rewriting the whole file.

### Fixes

- opencode: `codegraph install` now wires up the MCP server in the file opencode actually reads — previously it wrote to a config file opencode ignores by default, so the CodeGraph entry never appeared in any opencode session; re-run `codegraph install --target=opencode` after upgrading so the entry lands in the right place.

## [0.7.7] - 2026-05-17

### New Features

- `codegraph install` now sets up Claude Code, Cursor, Codex CLI, and opencode from one multi-select prompt, with any agents it detects pre-checked, so a single install wires up every editor you use (#137).
- You can install non-interactively for scripting and CI with flags like `--target`, `--location`, `--yes`, `--no-permissions`, and `--print-config`.
- `codegraph init` now auto-wires project-local agent config for any agent you installed globally, so one global `codegraph install` works in every project you open without re-installing per project.
- Agent instructions are now agent-agnostic and tell each agent to trust codegraph results instead of re-verifying with grep, fixing the case where Cursor and Codex fell back to native search even with codegraph available.
- The install prompts are clearer: the agent picker comes first, and the separate "install the CLI on your PATH" and "apply to all projects or just this one" questions no longer both read as "Global".

### Fixes

- Cursor: a globally-installed codegraph no longer reports "not initialized" in every workspace; the installer now passes the correct project path into Cursor's MCP config to work around Cursor launching MCP servers with the wrong working directory.

Thanks @andreinknv for the substantive draft this release was based on.

## [0.7.6] - 2026-05-13

### Fixes

- Fixed the `codegraph` command failing with `permission denied` right after a fresh global install — the 0.7.5 package shipped the CLI without its executable bit, so your shell refused to run it. New installs work out of the box. If you're stuck on 0.7.5, upgrade to 0.7.6 or unblock yourself in place by making the installed binary executable with `chmod +x`.
