# Changelog

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]

### 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

- **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# 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

- 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`.
