CLAUDE.md:290 and ARCHITECTURE.md:159 were missed when WARN was bumped
0.60 → 0.75 in d75402bb (v1.6.4.0, "cut Haiku classifier FP from 44% to

and BROWSER.md:743 was updated alongside that commit; CLAUDE.md and
ARCHITECTURE.md still read 0.60.
Also adds the SOLO_CONTENT_BLOCK: 0.92 entry to CLAUDE.md (already in
security.ts:50 and BROWSER.md:745, missing from CLAUDE.md's threshold

No code change. No behavior change. Pure doc-vs-code alignment.

* fix: Korean/CJK IME input and rendering in Sidebar Terminal
Fixes#1272
This commit addresses three separate Korean/CJK bugs in the Sidebar Terminal:
**Bug 1 - IME Input**: Korean text typed via IME composition was not
reaching the PTY correctly. Added compositionstart/compositionend event
listeners to suppress partial jamo fragments and only send the final
composed string.
**Bug 2a - Font Rendering**: Added CJK monospace font fallbacks
("Noto Sans Mono CJK KR", "Malgun Gothic") to both the xterm.js
fontFamily config and the CSS --font-mono variable. This ensures
consistent cell-width calculations for Korean characters.
**Bug 2b - UTF-8 Boundary Detection**: Added buffering logic to prevent
multi-byte UTF-8 characters (Korean is 3 bytes) from being split across
WebSocket chunks. This follows the same pattern as PR #1007 which fixed
the sidebar-agent path, but extends it to the terminal-agent path.
Special thanks to @ldybob for the excellent root cause analysis and
proposed solutions in issue #1272.
Tested on WSL2 + Windows 11 with Korean IME.
* fix(ship): tighten Plan Completion gate (VAS-449 remediation)
VAS-446 shipped with a PLAN.md acceptance criterion (domain-hq has
/docs/dashboard.md) silently skipped. /ship's Plan Completion subagent
existed at ship time (added in v1.4.1.0) but the gate let the failure
through. Four structural fixes:
1. Path concreteness rule: items naming a concrete filesystem path MUST
be classified DONE/NOT DONE via [ -f <path> ], never UNVERIFIABLE.
2. Validator detection: CONTENT-SHAPE items scan target repo's
package.json for validate-* scripts and run them before falling back
to UNVERIFIABLE.
3. Per-item UNVERIFIABLE confirmation: replaces blanket "I've checked
each one" with per-item Y/N/D loop. The blanket-confirm path is the
exact failure VAS-449 surfaced.
4. Subagent fail-closed: if Plan Completion subagent + inline fallback
both fail, surface explicit AskUserQuestion instead of silent pass.
Replaces the prior "Never block /ship on subagent failure" fail-open.
Locked in by test/ship-plan-completion-invariants.test.ts (5 assertions,
no LLM dependency, ~60ms).

* fix(browse): bash.exe wrap for telemetry on Windows
reportAttemptTelemetry() in browse/src/security.ts calls spawn(bin, args)
where bin is the gstack-telemetry-log bash script. On Windows this fails
silently with ENOENT — CreateProcess can't dispatch on shebang lines.
Adopts v1.24.0.0's Bun.which + GSTACK_*_BIN override pattern (from
browse/src/claude-bin.ts:resolveClaudeCommand, introduced in #1252) for
resolving bash.exe. resolveBashBinary() honors GSTACK_BASH_BIN absolute-path
or PATH-resolvable override, falling back to Bun.which('bash') which finds
Git Bash on the standard Windows install.
buildTelemetrySpawnCommand() wraps the script invocation on win32 only;
POSIX path is bit-identical. Returns null when bash can't be resolved on
Windows so caller skips spawn — local attempts.jsonl audit trail keeps
working without surfacing a Windows-only failure.
8 new unit tests cover resolveBashBinary (POSIX bash, absolute override,
quote-stripping, BASH_BIN fallback, empty-PATH null) and buildTelemetrySpawnCommand
(POSIX pass-through, win32 bash wrap, win32 null on unresolvable, arg-array
immutability).
POSIX path is bit-identical — Bun.which('bash') on Linux/macOS returns the
same /bin/bash or /usr/bin/bash that the old hardcoded spawn relied on.
* fix(make-pdf): Bun.which-based binary resolution for browse + pdftotext on Windows
Extends v1.24.0.0's Bun.which + GSTACK_*_BIN override pattern (introduced in
browse/src/claude-bin.ts via #1252) to the two other binary resolvers in the
codebase: make-pdf/src/browseClient.ts:resolveBrowseBin and
make-pdf/src/pdftotext.ts:resolvePdftotext.
Same Windows quirks (fs.accessSync(X_OK) degrades to existence-check; `which`
isn't available outside Git Bash; bun --compile --outfile X emits X.exe), same
Bun.which-based fix shape, same env override convention.
Changes:
- GSTACK_BROWSE_BIN / GSTACK_PDFTOTEXT_BIN as the v1.24-aligned overrides;
BROWSE_BIN / PDFTOTEXT_BIN remain as back-compat aliases.
- Bun.which() replaces execFileSync('which', ...) for PATH lookup. Handles
Windows PATHEXT natively; no more `where`-vs-`which` branch.
- findExecutable(base) helper exported from each module, probes .exe/.cmd/.bat
after the bare-path miss on win32. Linux/macOS behavior is bit-identical
(isExecutable short-circuits before the win32 branch ever runs).
- macCandidates renamed posixCandidates (always was — /opt/homebrew, /usr/local,
/usr/bin). No Windows candidates added; Poppler installs scatter across
Scoop/Chocolatey/portable zips and guessing causes false positives.
- Error messages get a Windows install hint (scoop install poppler / oschwartz10612)
and `setx` example for GSTACK_*_BIN.
- Pre-existing test 'honors BROWSE_BIN when it points at a real executable'
was hardcoded /bin/sh — made cross-platform via a REAL_EXE constant
(cmd.exe on win32, /bin/sh on POSIX). Was a Windows-CI blocker on its own.
Coordination: PR #1094 (@BkashJEE) covered browseClient.ts independently with a
narrower scope; this PR's pdftotext + cross-platform tests + GSTACK_*_BIN naming
are additive. Either order of merge works.
Test plan:
- bun test make-pdf/test/browseClient.test.ts make-pdf/test/pdftotext.test.ts
on win32 — 29 pass, 0 fail (12 new assertions: findExecutable POSIX/win32/null,
resolveBrowseBin GSTACK_BROWSE_BIN + BROWSE_BIN + precedence + quote-strip,
same shape for resolvePdftotext + Windows install hint in error message).
- POSIX branch unchanged — fs.accessSync(X_OK) on Linux/macOS short-circuits
before any win32 logic runs, matching the v1.24 claude-bin.ts pattern.
* fix(browse): NTFS ACL hardening for Windows state files via icacls
gstack's ~/.gstack/ state directory holds bearer tokens, canary tokens, agent
queue contents (with prompt history), session state, security-decision logs,
and saved cookie bundles — all written with { mode: 0o600 } / 0o700. On Windows,
those mode bits are a silent no-op: Node's fs module doesn't translate POSIX
modes to NTFS ACLs, and inherited ACLs leave every "restricted" file readable
by other principals on the machine (verified via icacls — six ACEs, the
intended user is the LAST of six).
Threat model is non-trivial on:
- Self-hosted CI runners (different service account on the same Windows box
can read developer tokens, canary tokens, prompt history)
- Shared development machines (agencies, studios, lab environments)
- Multi-tenant servers with shared home directories
Orthogonal to v1.24.0.0's binary-resolution work — complementary at the write
side. v1.24's bin/gstack-paths resolves ~/.gstack/ correctly across plugin /
global / local installs; this PR ensures files written into those resolved
paths actually get the POSIX 0o600 semantic translated to NTFS.
The fix:
- New browse/src/file-permissions.ts (158 LOC, 5 public + 1 test-reset).
restrictFilePermissions / restrictDirectoryPermissions wrap chmod (POSIX)
or icacls /inheritance:r /grant:r <user>:(F) (Windows). writeSecureFile /
appendSecureFile / mkdirSecure are drop-in wrappers for the common patterns.
- 19 call sites converted across 9 source files: browser-manager.ts,
browser-skill-write.ts, cli.ts, config.ts, meta-commands.ts,
security-classifier.ts, security.ts (4 sites), server.ts (5 sites),
terminal-agent.ts (8 sites), tunnel-denial-log.ts.
- (OI)(CI) inheritance flags on directories mean files created via fs.write*
*inside* an mkdirSecure-created dir inherit the owner-only ACL automatically
— important for tunnel-denial-log.ts where appends use async fsp.appendFile.
Error handling: icacls failures (nonexistent path, missing icacls.exe, hardened
environments) log a one-shot warning to stderr and proceed. Once-per-process
gating prevents log spam if the condition persists. Filesystem stays
functional; the file just ends up with inherited ACLs.
Test plan:
- bun test browse/test/file-permissions.test.ts — 13 pass, 0 fail (POSIX
mode-bit assertions, Windows no-throw, mkdir idempotence, recursive
creation, Buffer payloads, append-creates-then-reapplies-once semantics)
- bun test browse/test/security.test.ts — 38 pass, 0 fail (existing security
test suite plus the bash-binary resolution tests added in fix#1119; the
converted writeFileSync/appendFileSync/mkdirSync sites in security.ts
integrate cleanly)
- Empirical icacls before/after on a real file — 6 ACEs → 1 ACE
- bun build typecheck on all modified files — clean (server.ts has a
pre-existing playwright-core/electron resolution issue unrelated to this PR)
POSIX behavior is bit-identical to old code — fs.chmodSync(path, 0o6XX) on the
helper's POSIX branch matches the inline { mode: 0o6XX } it replaces. Linux
and macOS see no behavior change.
Inviting pushback on three judgment calls (in PR description):
1. icacls vs npm library
2. ACL scope — just user, or user + SYSTEM?
3. Graceful degradation — once-per-process warn, not silent, not hard-fail.
* fix(browse): declare lastConsoleFlushed to restore console-log persistence
flushBuffers() references a `lastConsoleFlushed` cursor at server.ts:337
and assigns it at :344, but the `let lastConsoleFlushed = 0;`
declaration is missing — only the network and dialog siblings are
declared at lines 327-328.
Result: every 1-second flushBuffers tick (line 376) throws
`ReferenceError: lastConsoleFlushed is not defined`, gets swallowed by
the catch at line 369 ("[browse] Buffer flush failed: ..."), and the
console branch's append never runs. browse-console.log is never
written in any production deployment since this regressed.
Discovered by stress-testing the daemon with 15 concurrent CLIs against
cold state — the race surfaced the buffer-flush error spam in one
spawned daemon's stderr. Verified by running the daemon against a real
file:// page with console.log events: in-memory `browse console`
returns the entries, but `.gstack/browse-console.log` is never created
on disk.
Regression introduced by 1a100a2a "fix: eliminate duplicate command
sets in chain, improve flush perf and type safety" — the flush refactor
switched from `Bun.write` to `fs.appendFileSync` and added the
`lastConsoleFlushed` cursor pattern alongside its network/dialog
siblings, but missed the matching `let` declaration. Tests don't
currently exercise flushBuffers, so the regression shipped silently.
Fix:
- Declare `let lastConsoleFlushed = 0;` next to `lastNetworkFlushed`
and `lastDialogFlushed` (browse/src/server.ts:327)
- Add a source-level guard test
(browse/test/server-flush-trackers.test.ts) that fails any future
refactor that adds a fourth `last*Flushed` cursor without the
matching declaration. Same pattern as terminal-agent.test.ts and
dual-listener.test.ts — read source as text, assert invariant, no
daemon required.
Test plan:
- [x] New regression test fails on current main, passes with the fix
- [x] `bun run build` clean
- [x] Manual smoke: spawn daemon -> goto file:// page with
console.log -> wait 4s -> .gstack/browse-console.log now
exists with the expected entries (163 bytes vs zero before)

* fix(browse): per-process state-file temp path to fix concurrent-write ENOENT
The daemon writes `.gstack/browse.json` via the standard atomic-rename
pattern: `writeFileSync(tmp, …) → renameSync(tmp, stateFile)`. Four
sites in server.ts use this pattern (initial daemon-startup state at
:2002, /tunnel/start handler at :1479, BROWSE_TUNNEL=1 inline tunnel
update at :2083, BROWSE_TUNNEL_LOCAL_ONLY=1 update at :2113), and all
four hard-code the same temp filename `${stateFile}.tmp`.
Under concurrent writers the shared filename races on the rename:
t0 Writer A: writeFileSync(stateFile + '.tmp', payloadA)
t1 Writer B: writeFileSync(stateFile + '.tmp', payloadB) // overwrites A
t2 Writer A: renameSync(stateFile + '.tmp', stateFile) // moves B's payload
t3 Writer B: renameSync(stateFile + '.tmp', stateFile) // ENOENT — file gone
Reproduced empirically with 15 concurrent CLIs against a fresh `.gstack/`:
[browse] Failed to start: ENOENT: no such file or directory,
rename '…/.gstack/browse.json.tmp' -> '…/.gstack/browse.json'
Pre-fix success rate: **0 / 15** under cold-start race.
Post-fix success rate: **15 / 15**, zero ENOENT.
Fix:
- New `tmpStatePath()` helper (server.ts:333) returns
`${stateFile}.tmp.${pid}.${randomBytes(4).toString('hex')}`
- All 4 call sites use `tmpStatePath()` instead of the shared literal
- Atomic rename still gives last-writer-wins semantics on the final
state.json content; only behavior change is that concurrent writers
no longer kill each other on the rename step
Source-level guard test (browse/test/server-tmp-state-path.test.ts)
locks two invariants: (1) no remaining `stateFile + '.tmp'` literals,
(2) every state-write `writeFileSync` call uses `tmpStatePath()`. Same
read-source-as-text pattern as terminal-agent.test.ts and
dual-listener.test.ts — no daemon required, runs in tier-1 free.
Test plan:
- [x] Targeted source-level guard test passes (3 / 0)
- [x] `bun run build` clean
- [x] Live regression: 15 concurrent CLIs against cold state →
15 / 15 healthy, 0 ENOENT (vs 0 / 15 pre-fix)
- [x] No `.tmp.*` orphans left behind after rename succeeds
- [x] Related test cluster (server-auth, dual-listener, cdp-mutex,
findport) — same pre-existing flakes as `main`, no new
regressions introduced

* fix(browse): clear refs when iframe auto-detaches in getActiveFrameOrPage
Asymmetric cleanup between two equivalent staleness conditions:
onMainFrameNavigated() → clearRefs() + activeFrame = null ✓
getActiveFrameOrPage() → activeFrame = null (refs NOT cleared) ✗
Both paths see the same staleness condition — refs were captured
against a frame that no longer exists. The main-frame path correctly
clears both pieces of state. The iframe-detach path nulls the frame
but leaves the refMap intact.
The lazy click-time check in `resolveRef` (tab-session.ts:97) partially
saves us — `entry.locator.count()` on a detached-frame locator throws
or returns 0, so the click errors out as "Ref X is stale". But the
user has no signal that frame context silently changed underfoot: the
next `snapshot` runs against `this.page` (main) while old iframe refs
still litter `refMap` with the same role+name keys. New refs collide
with stale ones, the resolver picks one at random, the user clicks
the wrong element.
TODOS.md line 816-820 documents "Detached frame auto-recovery" as a
shipped iframe-support feature in v0.12.1.0. This restores the
documented intent — the recovery should leave the session in a clean
state, not a half-cleared one.
Fix: 1 line — add `this.clearRefs()` next to `this.activeFrame = null`
inside the if-branch.
Test plan:
- [x] New regression test: 4/4 pass
- refs cleared when getActiveFrameOrPage detects detached iframe
- refs preserved when active frame is still attached (no regression)
- refs preserved when no frame set (page-level path untouched)
- matches onMainFrameNavigated symmetry — both paths reach the
same clean end state
- [x] `bun run build` clean

* fix(codex): resolve python for JSON parser
* fix: add fail-fast probe for base branch in ship step 12
* fix(plan-devex-review): remove contradictory plan-mode handshake
* fix(design): honor Retry-After header in variants 429 handler
Closes#1244.
The 429 handler in `generateVariant` discarded the `Retry-After` response
header and fell straight through to a local exponential schedule (2s/4s/8s).
In image-generation batches, that burns retry attempts inside the provider's
cooldown window and the request never recovers.
Now we parse `Retry-After` per RFC 7231 — both delta-seconds (`Retry-After: 5`)
and HTTP-date (`Retry-After: Fri, 31 Dec 1999 23:59:59 GMT`). Honored waits
are capped at 60s to bound stalls from hostile or buggy headers. Delta-seconds
are validated as digits-only (rejects `2abc`). When `Retry-After` is honored
(including 0 / past-date "retry now"), the next iteration's leading exponential
sleep is skipped so we don't double-wait. Invalid or missing headers fall
through to the existing exponential schedule unchanged.
Behavior matrix:
| Header | Behavior |
|---------------------------------|-------------------------------------------|
| Retry-After: 5 | wait 5s, skip leading on next attempt |
| Retry-After: 999999 | capped to 60s, skip leading |
| Retry-After: 2abc | invalid, fall through to exponential |
| Retry-After: 0 | wait 0, skip leading (retry immediately) |
| Retry-After: <past HTTP-date> | wait 0, skip leading |
| Retry-After: <future date> | wait diff capped at 60s, skip leading |
| no header | fall through to existing exponential |
`generateVariant` now accepts an optional `fetchFn` parameter (defaults to
`globalThis.fetch`) so tests can inject a stub. Production call sites are
unchanged.
Tests cover the five behavior buckets above, asserting both the 1st-to-2nd
call timing gap and call counts. All five pass in ~8s.

* fix(docs): correct per-skill symlink removal snippet in README uninstall
Closes#1130.
The manual-uninstall fallback in `## Uninstall` → `### Option 2` used
`find ~/.claude/skills -maxdepth 1 -type l`, which finds nothing on real
installs. Each `~/.claude/skills/<name>/` is a real directory, and only
`<name>/SKILL.md` inside it is a symlink into `gstack/`. The find never
matched, so the snippet silently removed nothing.
Replace with a directory walk that inspects each `<name>/SKILL.md`:
find ~/.claude/skills -mindepth 1 -maxdepth 1 -type d ! -name gstack
→ check $dir/SKILL.md is a symlink → readlink it
→ if target is gstack/* or */gstack/*: rm -f the link, rmdir the dir
(only if empty — preserves any user-added files)
Excludes the top-level `gstack/` dir from the walk; that's removed by
step 3 of the same uninstall block.
`bin/gstack-uninstall` (the script-mode path) already handles the layout
correctly via its own walk; only this manual fallback needed updating.

* fix(gemini-adapter): detect new ~/.gemini/oauth_creds.json auth path
gemini-cli >=0.30 stores OAuth credentials at ~/.gemini/oauth_creds.json
instead of the legacy ~/.config/gemini/ directory. The benchmark adapter's
availability check now succeeds for users on recent gemini-cli releases

Both paths are accepted so users on older versions still work.
* fix(browser): add --no-sandbox for root user on Linux/WSL2
Chromium's sandbox can't initialize when running as root on Linux,
causing an immediate exit. Extend the existing CI/CONTAINER check to
also cover this case, keeping the Windows-safe `typeof getuid` guard.
* security: pass cwd to git via execFileSync, not interpolation through /bin/sh
`bin/gstack-memory-ingest.ts:632-643` ran `execSync(\`git -C ${JSON.stringify(cwd)}
remote get-url origin 2>/dev/null\`, ...)`. JSON.stringify escapes `"` and `\`
but not `$` or backticks, so a `cwd` of `"$(touch /tmp/marker)"` survived JSON
quoting and detonated under /bin/sh's command-substitution-inside-double-quotes.
`cwd` originates from transcript JSONL records under
`~/.claude/projects/<encoded-cwd>/<uuid>.jsonl` and
`~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`. The walker grabs the first
`.cwd` it sees per session. That's an untrusted surface in the gstack threat
model — the L1-L6 sidebar security stack exists exactly because agent
transcripts can carry attacker-influenced text. Two pivots above the local
same-uid bar: (a) prompt-injection appending `cwd="$(...)"` to the active
session log turns the next /sync-gbrain run into RCE under the user's uid;
(b) cross-machine transcript share (a colleague's `.claude/projects` snippet
untar'd into HOME, a documented gbrain dogfooding shape) → RCE on first sync.
Fix swaps the one execSync for `execFileSync("git", ["-C", cwd, "remote",
"get-url", "origin"], ...)`. No shell, argv passed directly to git. The same
module already uses execFileSync for `gbrainAvailable()` (line 762 pre-patch)
and `gbrainPutPage()` (line 816 pre-patch) — this single execSync was the
outlier.
Test: `gstack-memory-ingest security: untrusted cwd cannot trigger shell
substitution` plants a Claude-Code-shaped JSONL with cwd=`$(touch <marker>)`
and asserts the marker file is not created after `--incremental --quiet`.
Negative control: with the patch reverted, the test fails (marker created);
with the patch applied, it passes (18/18 in test/gstack-memory-ingest.test.ts).
* security: gate domain-skill auto-promote on classifier_score > 0
`browse/src/domain-skill-commands.ts:140` (handleSave) writes
`classifier_score: 0` with the comment "L4 deferred to load-time / sidebar-agent
fills this in on first prompt-injection load." But CLAUDE.md "Sidebar
architecture" documents that sidebar-agent.ts was ripped, and grep for
recordSkillUse + classifierFlagged callers across browse/src/ returns zero hits
outside the module under test.
Net effect: every quarantined skill that survives three benign uses without
flag (`recordSkillUse(... , classifierFlagged: false)` x3) auto-promotes to
`active` and lands in prompt context wrapped as UNTRUSTED on every subsequent
visit to that host. The L4 score that was supposed to gate the promotion was
never written — the production save path puts 0 on disk and nothing later
updates it.
Threat model: a domain-skill body authored by an agent under the influence of
a poisoned page (the new `gstackInjectToTerminal` PTY path runs no L1-L3
either) would lose its auto-promote barrier after three uses. The exploit
isn't single-step but the bar is exactly N=3 prompt-injection-shaped uses on
a hostile page, which is well within reach.
Fix adds a single condition to the auto-promote gate in `recordSkillUse`:
if (state === 'quarantined' && useCount >= PROMOTE_THRESHOLD &&
flagCount === 0 && current.classifier_score > 0) {
state = 'active';
}
`classifier_score` is set once at writeSkill and never updated. Production
saves it as 0 (handleSave), so the gate stays closed; existing tests that
explicitly pass `classifierScore: 0.1` still auto-promote (the auto-promote
path is preserved for the day L4 is rewired).
Manual promotion via `domain-skill promote-to-global` is unaffected (it goes
through `promoteToGlobal` which has its own state-machine guard at line 337+).
Test: new regression case `does NOT auto-promote when classifier_score is 0
(production handleSave shape)` plants a skill with classifierScore=0 (matches
domain-skill-commands.ts:140), runs three uses without flag, asserts the skill
stays quarantined and readSkill returns null. Negative control: revert the
patch, the test fails with `Received: "active"`. With the patch: 15/15 pass.
* fix(ship): port #1302 SKILL.md edits to .tmpl + resolver source
PR #1302 added Verification Mode + UNVERIFIABLE classification + per-item
confirmation gate to ship/SKILL.md, but only the generated SKILL.md was
edited — not the .tmpl source or scripts/resolvers/review.ts. The next
`bun run gen:skill-docs` run would have wiped the changes.
Port the same content into the resolver and .tmpl so regeneration produces
the intended output.
* ci(windows): extend free-tests lane to cover icacls + Bun.which resolvers from fix-wave PRs
Closes #1306/#1307/#1308 validation gap. The four newly-added test files
already have process.platform guards so they run safely on both POSIX and
Windows lanes — only platform-relevant assertions execute on each.
Tests added to the windows-latest lane:
- browse/test/file-permissions.test.ts (#1308 icacls + writeSecureFile)
- browse/test/security.test.ts (#1306 bash.exe wrap pure-function path)

* test(codex): live flag-semantics smoke for codex exec resume
Closes#1270's regex-only test gap. PR #1270 asserted that codex/SKILL.md's
`codex exec resume` invocation drops -C/-s and uses sandbox_mode config.
That regex catches the skill template regressing, but not codex CLI itself
flipping flag semantics again.
This test probes `codex exec resume --help` and asserts the surface gstack
relies on: -c/sandbox_mode is accepted, top-level -C is absent. Skips
silently when codex isn't on PATH, so dev machines without codex installed
never see it fail.
* chore: regen SKILL.md after fix wave
One regen commit at the end of the merge wave per the plan. plan-devex-review
loses the contradictory plan-mode handshake (#1333). review/SKILL.md picks up
the Verification Mode + UNVERIFIABLE classification additions that #1302
authored against ship/SKILL.md (same resolver shared between ship and review
modes).
* fix(server.ts): keep fs.writeFileSync for state-file writes
#1308's writeSecureFile wrapper added Windows icacls hardening for the
4 state-file write sites in server.ts, but #1310's regression test grep's
for fs.writeFileSync(tmpStatePath()) calls. The two changes are technically
compatible only if the test relaxes — keeping the test strict (the safer
choice for catching regressions on the cold-start race) means the 4 state-
file sites stay on fs.writeFileSync(..., { mode: 0o600 }).
POSIX 0o600 hardening is preserved on those 4 sites. Windows icacls
hardening still applies to all the other writeSecureFile call sites
#1308 added (auth.json, mkdirSecure, etc.).
Also refreshes golden baselines after #1302 / port + minor wording tweak
in scripts/resolvers/review.ts to keep gen-skill-docs.test.ts assertion
'Cite the specific file' satisfied.
* v1.30.0.0: fix wave — 21 community PRs + 2 closing fixes for Windows + codex CI gaps
Headline release. Browse stops dropping console logs, cold-start race
fixed, codex resume works without python3, Windows hardening (icacls +
Bun.which + bash.exe wrap), ship gate gets VAS-449 remediation, two
closing fixes that put icacls/Bun.which/codex flag semantics under CI.
* test(domain-skills): cover #1369 classifier_score=0 quarantine + score>0 promote path
The pre-existing T6 test seeded skills via writeSkill (which defaults
classifier_score to 0 until L4 is rewired) and then expected 3 uses to
auto-promote. PR #1369 added `current.classifier_score > 0` to the gate
specifically to block that path — a quarantined skill written under the
influence of a poisoned page would otherwise auto-promote after three
benign uses.
Updated test asserts both halves of the new contract:
- classifier_score=0 + 3 uses → stays quarantined (the security guarantee)
- classifier_score>0 + 3 more uses → promotes to active (unblock path)
Catches both regressions: the gate going away (would re-allow the bypass)
and the unblock path breaking (would silently quarantine all skills
forever once L4 is rewired).

* feat(gbrain-sync): queue primitives + writer shims
Adds bin/gstack-brain-enqueue (atomic append to sync queue) and
bin/gstack-jsonl-merge (git merge driver, ts-sort with SHA-256 fallback).
Wires one backgrounded enqueue call into learnings-log, timeline-log,
review-log, and developer-profile --migrate. question-log and
question-preferences stay local per Codex v2 decision.
gstack-config gains gbrain_sync_mode (off/artifacts-only/full) and
gbrain_sync_mode_prompted keys, plus GSTACK_HOME env alignment so
tests don't leak into real ~/.gstack/config.yaml.
* feat(gbrain-sync): --once drain + secret scan + push
bin/gstack-brain-sync is the core sync binary. Subcommands: --once
(drain queue, allowlist-filter, privacy-class-filter, secret-scan
staged diff, commit with template, push with fetch+merge retry),
--status, --skip-file <path>, --drop-queue --yes, --discover-new
(cursor-based detection of artifact writes that skip the shim).
Secret regex families: AWS keys, GitHub tokens (ghp_/gho_/ghu_/ghs_/
ghr_/github_pat_), OpenAI sk-, PEM blocks, JWTs, bearer-token-in-JSON.
On hit: unstage, preserve queue, print remediation hint (--skip-file
or edit), exit clean. No daemon — invoked by preamble at skill
boundaries.
* feat(gbrain-sync): init, restore, uninstall, consumer registry
bin/gstack-brain-init: idempotent first-run. git init ~/.gstack/,
.gitignore=*, canonical .brain-allowlist + .brain-privacy-map.json,
pre-commit secret-scan hook (defense-in-depth), merge driver registration
via git config, gh repo create --private OR arbitrary --remote <url>,
initial push, ~/.gstack-brain-remote.txt for new-machine discovery,
GBrain consumer registration via HTTP POST.
bin/gstack-brain-restore: safe new-machine bootstrap. Refuses clobber
of existing allowlisted files, clones to staging, rsync-copies tracked
files, re-registers merge drivers (required — not cloned from remote),
rehydrates consumers.json, prompts for per-consumer tokens.
bin/gstack-brain-uninstall: clean off-ramp. Removes .git + .brain-*
files + consumers.json + config keys. Preserves user data (learnings,
plans, retros, profile). Optional --delete-remote for GitHub repos.
bin/gstack-brain-consumer + bin/gstack-brain-reader (symlink alias):
registry management. Internal 'consumer' term; user-facing 'reader'
per DX review decision.
* feat(gbrain-sync): preamble block — privacy gate + boundary sync
scripts/resolvers/preamble/generate-brain-sync-block.ts emits bash that
runs at every skill invocation:
- Detects ~/.gstack-brain-remote.txt on machines without local .git
and surfaces a restore-available hint (does NOT auto-run restore).
- Runs gstack-brain-sync --once at skill start to drain any pending
writes (and at skill end via prose instruction).
- Once-per-day auto-pull (cached via .brain-last-pull) for append-only
JSONL files.
- Emits BRAIN_SYNC: status line every skill run.
Also emits prose for the host LLM to fire the one-time privacy
stop-gate (full / artifacts-only / off) when gbrain is detected and
gbrain_sync_mode_prompted is false. Wired into preamble.ts composition.
* test(gbrain-sync): 27-test consolidated suite
test/brain-sync.test.ts covers:
- Config: validation, defaults, GSTACK_HOME env isolation
- Enqueue: no-op gates, skip list, concurrent atomicity, JSON escape
- JSONL merge driver: 3-way + ts-sort + SHA-256 fallback
- Init + sync: canonical file creation, merge driver registration,
push-reject + fetch+merge retry path
- Init refuses different remote (idempotency)
- Cross-machine restore round-trip (machine A write → machine B sees)
- Secret scan across all 6 regex families (AWS, GH, OpenAI, PEM, JWT,
bearer-JSON). --skip-file unblock remediation
- Uninstall removes sync config, preserves user data
- --discover-new idempotence via mtime+size cursor
Behaviors verified via integration smokes during implementation. Known
follow-up: bun-test 5s default timeout needs 30s wrapper for
spawnSync-heavy tests.
* docs(gbrain-sync): user guide + error lookup + README section
docs/gbrain-sync.md: setup walkthrough, privacy modes, cross-machine
workflow, secret protection, two-machine conflict handling, uninstall,
troubleshooting reference.
docs/gbrain-sync-errors.md: problem/cause/fix index for every
user-visible error. Patterned on Rust's error docs + Stripe's API
error reference.
README.md: 'Cross-machine memory with GBrain sync' section near the
top (discovery moment), plus docs-table entry.
* chore: bump version and changelog (v1.7.0.0)
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
* chore: regenerate SKILL.md files for gbrain-sync preamble block
Re-runs bun run gen:skill-docs after adding generateBrainSyncBlock
to scripts/resolvers/preamble.ts in a2aa8a07. CI check-freshness
caught the drift. All 36 SKILL.md files regenerated with the new
skill-start bash block + privacy-gate prose + skill-end sync
instructions baked in.
* fix(test): session-awareness reads AskUserQuestion Format from a Tier 2+ SKILL.md
The test was reading ROOT/SKILL.md (browse skill, Tier 1) which never
contained '## AskUserQuestion Format' — that section is only emitted
for Tier 2+ skills by scripts/resolvers/preamble.ts. As a result the
agent was prompted with an empty format guide and only emitted
'RECOMMENDATION' intermittently, making the test flaky.
Pre-existing on main (same ROOT/SKILL.md shape there) — surfaced now
because the agent run didn't hit the RECOMMENDATION/recommend/option a
fallback strings in this particular attempt.
Fix: read from office-hours/SKILL.md (Tier 3, always has the section)
with a fallback that scans for the first top-level skill dir whose
SKILL.md contains the header. Future template moves won't break this
test again.
* feat(browse): domain-skills storage + state machine
New module browse/src/domain-skills.ts implements the per-site notes
the agent writes for itself, persisted as type:"domain" rows alongside
/learn's per-project learnings.
Three scopes layered: per-project default, global by explicit promotion.
Project-active shadows global for the same host.
State machine (T6 — codex outside-voice):
quarantined --3 uses w/o flag--> active(project) --promote--> global
^ |
+----- classifier flag during use
- Append-only JSONL with O_APPEND for atomic small writes
- Tolerant parser drops partial trailing line on read
- Tombstone for deletes (compactor cleans up later)
- Version log per (host, scope) enables rollback
- Hostname derived from active tab top-level origin (T3 confused-deputy fix)
- writeSkill rejects classifier_score >= 0.85 with structured error
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(browse): domain-skills storage + state machine
14 tests covering:
- T3 hostname normalization (lowercase, www. strip, port/path/query strip,
subdomain-exact preserved)
- T4 scope shadowing (per-project active shadows global for same host)
- T5 persistence (version monotonicity, tolerant parser drops partial line)
- T6 state machine (quarantined → active after N=3 uses, classifier-flag
blocks promotion, save-time score >= 0.85 rejected)
- Rollback by version log (restore prior body, advance version counter)
- Tombstone deletion (read returns null after delete)
All 14 pass in 27ms via bun test.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(browse): $B domain-skill subcommands
Wire the domain-skills storage layer into the browse CLI as a META command:
$B domain-skill save save body from stdin or --from-file
(host derived from active tab — T3)
$B domain-skill list list all skills visible to current project
$B domain-skill show <host> print skill body
$B domain-skill edit <host> open in $EDITOR
$B domain-skill promote-to-global <host> cross-project promotion (T4)
$B domain-skill rollback <host> [--global] restore prior version
$B domain-skill rm <host> [--global] tombstone
Save path runs L1-L3 content filters from content-security.ts (importable
in compiled binary, unlike L4 ML classifier — see CLAUDE.md). The L4
classifier scan happens in sidebar-agent at prompt-injection load time.
Output is structured (problem + cause + suggested-action) per DX D7.

* feat(browse): $B cdp escape hatch — deny-default allowlist + two-tier mutex
Codex T2: flip CDP posture to deny-default. Allowed methods enumerated in
cdp-allowlist.ts with (scope: tab|browser, output: trusted|untrusted,
justification) per entry.
Initial allowlist (~25 methods) covers:
- Accessibility tree extraction (read-only)
- DOM/CSS inspection (read-only)
- Performance metrics
- Tracing
- Emulation viewport/UA override
- Page screenshot/PDF capture (output is binary, no marker injection vector)
- Network.enable/disable (no bodies/cookies — those are exfil surfaces)
- Runtime.getProperties (NO evaluate/callFunctionOn — those would be RCE)
Page.navigate is INTENTIONALLY NOT allowed; agents use $B goto which
goes through the URL blocklist.
Codex T7: two-tier mutex. tab-scoped methods take per-tab lock; browser-
scoped take global lock that blocks all tab locks. 5s acquire timeout
yields CDPMutexAcquireTimeout (no silent hangs). All lock acquires use
try/finally so errors don't leak the lock.
Path A from spike: uses Playwright's newCDPSession() per page. No second
WebSocket, no need for --remote-debugging-port. CDPSession is cached
per page in a WeakMap and cleared on page close.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(browse): CDP allowlist + two-tier mutex
13 tests:
- Allowlist linter: every entry has 4 required fields, no duplicates,
justification length > 20 chars
- Deny-list verification: dangerous methods (Runtime.evaluate, Page.navigate,
Network.getResponseBody, Browser.close, Target.attachToTarget, etc.) are
NOT allowed (Codex T2 categories 4-7)
- Per-tab mutex serializes ops on same tab
- Per-tab mutex allows parallel ops across different tabs
- Global lock blocks tab locks; tab locks block global lock
- Acquire timeout yields CDPMutexAcquireTimeout (no silent hang)
- Timeout error names the tab id and the timeout budget
Also extends Network.disable justification to satisfy linter.

* feat(browse): telemetry signals + project-slug helper
Lightweight telemetry per DX D9: piggybacks on ~/.gstack/analytics/ pattern.
Hostname + aggregate counters only, no body content. GSTACK_TELEMETRY_OFF=1
silences. Fire-and-forget — never blocks calling path.
Signals fired so far:
- domain_skill_saved {host, scope, state, bytes}
- domain_skill_save_blocked {host, reason}
(domain_skill_fired and cdp_method_* fired in subsequent commits.)
Also extracts project-slug resolution into project-slug.ts so server.ts
and domain-skill-commands.ts share one cached lookup.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(browse): sidebar prompt-context injection + CDP telemetry
server.ts spawnClaude now:
- Imports per-project domain skill matching the active tab's hostname
via readDomainSkill()
- Wraps the body in UNTRUSTED EXTERNAL CONTENT envelope (so the L4
classifier in sidebar-agent sees it at load time per Eng D4)
- Appends as <domain-skill source="..." host="..." version="..."> block
- Fires domain_skill_fired telemetry (host, source, version)
- Calls recordSkillUse fire-and-forget so the auto-promote-after-N=3
state machine advances on each successful prompt injection
System prompt also gets a one-liner introducing $B domain-skill commands
to agents (DX D4 start-of-task discoverability hint).
cdp-bridge.ts fires:
- cdp_method_denied (drives next allow-list growth)
- cdp_method_lock_acquire_ms (P50/P99 quantile observability)
- cdp_method_called (allowed methods)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(browse): telemetry module
3 tests covering:
- logTelemetry writes JSONL with ts injected
- GSTACK_TELEMETRY_OFF=1 silences all events
- logTelemetry never throws on disk failures
Uses GSTACK_HOME env var to redirect writes to a tmp dir; the telemetry
module reads HOME lazily so test mutations take effect.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs: domain-skills reference + error lookup table
docs/domain-skills.md mirrors the layered shape of docs/gbrain-sync.md
(DX D8): how agents use it, state machine, storage layout, security model
(L1-L3 + L4 layered defense), error reference table.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(readme): browser-harness-js plug + domain-skills section
New "Domain skills + raw CDP escape hatch" section under "The sprint"
covering both v1.8.0.0 features. Plugs browser-use/browser-harness-js
as the no-rails alternative for users who want raw CDP without gstack's
security stack.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* chore: bump version and changelog (v1.8.0.0)
Branch-scoped bump on top of merged 1.7.0.0 base. CHANGELOG entry covers
the full v1.8.0.0 scope: $B domain-skill, $B cdp escape hatch, two-tier
mutex, telemetry signals, sidebar prompt-context injection. Includes
Codex outside-voice trail (7 of 20 findings resolved, 12 mooted by T1
scope drop).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* todos: 7 follow-ups from v1.8.0.0 review trail
P1: Self-authoring $B commands with out-of-process worker isolation
(Codex T1 deferred from v1.8.0.0 — needs real isolation design)
P2: Migrate /learn to SQLite (Codex T5 long-term primitive fix)
P2: Remove plan-mode handshake from /plan-devex-review (skill bug)
P3: GBrain skillpack publishing for domain-skills
P3: Replay/record demonstrated flows to domain-skills
P3: $B commands review batch-mode UX (alternative to inline approval)
P3: Heuristic command-gap watcher (DX D4 alternative C)
Each entry has the standard What/Why/Pros/Cons/Context/Effort/Priority/
Depends-on shape so anyone picking these up later has full context.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(browse): lazy GSTACK_HOME resolution in domain-skills
Module-level constants (GLOBAL_FILE, derived path) were evaluated at
module-load and cached. When E2E and unit tests run in the same Bun
test pass and set GSTACK_HOME differently, the second test sees the
first test's path. Switch to lazy gstackHome() / globalFile() / projectFile()
helpers so process.env mutations take effect.
Mirrors the pattern already used in telemetry.ts.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(browse): E2E gate-tier tests for domain-skills + CDP
domain-skills-e2e.test.ts (4 tests):
- save derives host from active tab top-level origin (T3)
- save lands quarantined; list surfaces it
- readSkill returns null until 3 uses without flag promote to active (T6)
- save without an active page errors with structured guidance
cdp-e2e.test.ts (8 tests):
- Accessibility.getFullAXTree returns wrapped JSON (allowed, untrusted-output)
- Performance.getMetrics returns plain JSON (allowed, trusted-output)
- Runtime.evaluate DENIED with structured guidance (T2 RCE block)
- Page.navigate DENIED (must use $B goto for blocklist routing)
- Network.getResponseBody DENIED (exfil block)
- malformed JSON params surfaces clear error
- non Domain.method format surfaces clear error
- $B cdp help returns help text
Both files boot a real Chromium via BrowserManager.launch() and exercise
the dispatch handlers end-to-end. Total 12 E2E tests in <2s.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs: regenerate SKILL.md files with new $B commands
bun run gen:skill-docs picks up the domain-skill and cdp META_COMMANDS
entries added in commands.ts. Both top-level SKILL.md and browse/SKILL.md
now list the new commands in their Meta and Inspection tables.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(fixtures): regenerate ship SKILL.md golden baselines for v1.7.0.0
Pre-existing failures inherited from garrytan/gbrain-support: the GBrain
Sync preamble block (added in v1.7.0.0) appears in regenerated SKILL.md
output but the golden baselines in test/fixtures/golden/ were never
updated. Three failures fixed:
golden-file regression > Claude ship skill matches golden baseline
golden-file regression > Codex ship skill matches golden baseline
golden-file regression > Factory ship skill matches golden baseline
Goldens regenerated by copying the current ship/SKILL.md, codex
.agents/skills/gstack-ship/SKILL.md, and .factory/skills/gstack-ship/SKILL.md
files. Diff is the v1.7.0.0 GBrain Sync preamble block + privacy stop-gate
(no behavioral changes — just preamble text).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* fix(brain-sync): bearer-token regex catches values with leading space
Pre-existing bug from v1.7.0.0: the bearer-token-json secret pattern
required values matching [A-Za-z0-9_./+=-]{16,}, which rejected the
"Bearer <token>" form because the literal space after "Bearer" wasn't
in the character class. Real Authorization headers use "Bearer <token>"
syntax, and the test fixture
'"authorization":"Bearer abcdef1234567890abcdef1234567890"'
sat unscanned despite being a leak-class secret.
One-character fix: add space to the value character class. Test
'gstack-brain-sync secret scan > blocks bearer-json' now passes.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(brain-sync): GSTACK_HOME isolation test compares mtime, not content
Pre-existing flaky test: the GSTACK_HOME-overrides-real-config test asserted
the real ~/.gstack/config.yaml does NOT contain "gbrain_sync_mode: full"
after the test. That fails for any user whose real config legitimately has
that key set from prior usage — the test's invariant is "the command did
not modify the real file," not "the real file lacks any specific value."
Switch to mtime + content snapshot: capture both BEFORE running the command,
then verify both are unchanged after. Also add a positive assertion that
the tmpHome config DID get the new key.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(skill-validation): exempt deliberate large fixtures from 2MB limit
Pre-existing failure: the "git tracks no files larger than 2MB" test
caught browse/test/fixtures/security-bench-haiku-responses.json (28.8MB
of replay data committed in v1.6.4.0 for security benchmark gate tests).
The test exists to catch accidentally-committed binaries (Mach-O dist
binaries, etc), not to forbid all large files. Add an explicit
LARGE_FIXTURE_EXEMPTIONS allowlist so deliberate replay fixtures pass
the gate while accidental binaries still fail.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(skill-token): mint scoped tokens per skill spawn
Wraps token-registry.createToken/revokeToken with skill-specific
clientId encoding (skill:<name>:<spawn-id>) and read+write defaults.
Skill scripts get a per-spawn capability token bound to browser-driving
commands; the daemon root token never leaves the harness.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(browse-client): SDK for browser-skill scripts
Thin wrapper over POST /command with bearer auth. Resolves daemon
port + token from GSTACK_PORT + GSTACK_SKILL_TOKEN env vars first
(set by $B skill run when spawning), falls back to .gstack/browse.json
for standalone debug runs.
Convenience methods cover the read+write surface skills typically need:
goto, click, fill, text, html, snapshot, links, forms, accessibility,
attrs, media, data, scroll, press, type, select, wait, hover, screenshot.
Low-level command(cmd, args) escape hatch for anything else.
This is the canonical SDK source. Each browser-skill ships a sibling
copy at <skill>/_lib/browse-client.ts so each skill is fully portable
and version-pinned.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(browser-skills): 3-tier storage helpers
listBrowserSkills() walks project > global > bundled (first-wins),
parses SKILL.md frontmatter, no INDEX.json. readBrowserSkill() does
the same for a single name. tombstoneBrowserSkill() moves a skill
into .tombstones/<name>-<ts>/ for recoverability.
Frontmatter parser handles the subset browser-skills need: scalars
(host, description, trusted, version, source), string lists
(triggers), and arg-mapping lists ([{name, description}, ...]).
Quoted values handle colons; trusted defaults to false.
Bundled tier path is auto-detected from the binary install location;
project tier comes from git rev-parse; global is ~/.gstack/. All tier
paths are overridable for hermetic tests.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* feat(browser-skills): \$B skill list/show/run/test/rm subcommands
handleSkillCommand dispatches to per-subcommand handlers; spawnSkill is
the load-bearing function that:
1. Mints a per-spawn scoped token (read+write only) bound to the
skill name + spawn-id.
2. Builds the spawn env:
- trusted: passes process.env minus GSTACK_TOKEN (defense in depth).
- untrusted: minimal allowlist (LANG, LC_ALL, TERM, TZ) + locked
PATH; explicitly drops anything matching TOKEN/KEY/SECRET/etc.
Also drops AWS_/AZURE_/GCP_/GOOGLE_APPLICATION_/ANTHROPIC_/OPENAI_/
GITHUB_/GH_/SSH_/GPG_/NPM_TOKEN/PYPI_ patterns.
3. Always injects GSTACK_PORT + GSTACK_SKILL_TOKEN last (cannot be
overridden by parent env).
4. Spawns bun run script.ts -- <args> with cwd=skillDir, captures
stdout (1MB cap), stderr, and timeout-kills past the deadline.
5. Revokes the token in finally{}, always.
list output prints the resolved tier inline so "why did it run that
one?" never becomes a debugging mystery (Codex finding #4 mitigation).
server.ts threads the listen port to meta-commands via MetaCommandOpts.daemonPort.

* feat(browser-skills): bundled hackernews-frontpage reference skill
Smallest interesting browser-skill: scrapes HN front page, returns
30 stories as JSON. No auth, stable HTML, fully fixture-tested.
Files:
SKILL.md frontmatter + prose
script.ts exports parseStoriesFromHtml(html)
main: goto + html + parse + JSON.stringify
_lib/browse-client.ts vendored copy of the SDK
fixtures/hn-2026-04-26.html captured front page (5 stories)
script.test.ts 13 assertions against the fixture
The parser is a pure function over HTML so script.test.ts runs
without a daemon (just imports parseStoriesFromHtml and asserts).
This exercises every Phase 1 component end-to-end:
- browse-client SDK (script imports browse from ./_lib/)
- 3-tier lookup (hackernews-frontpage lives in the bundled tier)
- scoped tokens (read+write is enough for goto + html)
- spawn lifecycle (\$B skill run hackernews-frontpage)
- file-fixture testing (\$B skill test hackernews-frontpage)
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(skill-validation): cover bundled browser-skills
Adds 7 assertions per bundled skill at <root>/browser-skills/<name>/:
- SKILL.md exists
- frontmatter parses with required fields (name/host/triggers/args)
- script.ts exists
- _lib/browse-client.ts exists and matches the canonical SDK byte-for-byte
- script.test.ts exists
- script.ts imports browse from ./_lib/browse-client
The byte-identical SDK check enforces the version-pinning contract:
when the canonical SDK at browse/src/browse-client.ts changes, every
bundled skill's _lib/ copy must be re-synced or this test fails.

* docs(designs): add BROWSER_SKILLS_V1 design doc
Captures the 13 locked decisions, two-axis trust model (daemon-side
scoped tokens + process-side env access), 3-tier lookup, file
layout, and full responses to all 8 Codex outside-voice findings.
Includes Phase 2-4 sketches for future branches.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(todos): replace self-authoring-\$B P1 with browser-skills phases
Phase 1 of the browser-skills design shipped on this branch (sidesteps
the in-daemon isolation problem the original P1 was blocked on). The
new entries enumerate the work that remains:
P1: Phase 2 (/scrape + /automate skill templates)
P2: Phase 3 (resolver injection at session start)
P2: Phase 4 (eval infra + fixture staleness + OS sandbox)
Cross-references docs/designs/BROWSER_SKILLS_V1.md for the full
architecture and the 8 Codex review findings + responses.

* release: v1.9.0.0 — browser-skills runtime
VERSION 1.8.0.0 → 1.9.0.0. CHANGELOG entry leads with what humans
can do today (hand-write deterministic browser scripts, run them in
200ms via \$B skill run). Notes explicitly that agent authoring
lands in next release; no fabricated perf numbers.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* test(browser-skills-e2e): exercise dispatch with bundled hackernews-frontpage
Covers the full \$B skill list/show/test pipeline against the real
bundled reference skill (defaultTierPaths picks up <repo>/browser-skills/).
Verifies frontmatter shape, the three-tier walk surfaces the bundled
entry, and \$B skill test successfully runs the bundled script.test.ts
in a child bun process.
\$B skill run end-to-end against the live network is intentionally NOT
covered here (would be flaky against news.ycombinator.com); the spawn
lifecycle is exercised in browser-skill-commands.test.ts using inline
synthetic skills.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs: regen SKILL.md to surface the skill META command
bun run gen:skill-docs picked up the new \`skill\` command from
COMMAND_DESCRIPTIONS in browse/src/commands.ts.

* release: bump v1.9.0.0 → v1.13.0.0
Main shipped through v1.11.1.0 while this branch was in flight; v1.12.x
is presumed claimed by another in-flight branch. Use v1.13.0.0 as the
next available slot.
Updated VERSION, package.json, and the CHANGELOG header. Entry body
unchanged.

* release: bump v1.13.0.0 → v1.16.0.0
Main shipped v1.13.0.0 (claude outside-voice skill), v1.14.0.0
(sidebar REPL), and v1.15.0.0 (slim preamble + plan-mode E2E)
while this branch was in flight. Use v1.16.0.0 as the next
available slot.

* feat(browse-skills): atomic write helper for /skillify (D3)
stageSkill writes a candidate skill into ~/.gstack/.tmp/skillify-<spawnId>/
with restrictive perms. commitSkill does an atomic fs.renameSync into the
final tier path with realpath/lstat discipline (refuses symlinked staging
dirs, refuses to clobber existing skills). discardStaged is the cleanup
path for test failures and approval rejections, idempotent and bounded
to the per-spawn wrapper. validateSkillName enforces lowercase/digits/
dashes only, no path-escape characters.
Implements the D3 contract from the v1.19.0.0 plan review: never a
half-written skill on disk. Test fail or approval reject = rm -rf the
temp dir, no tombstone for never-approved skills.
Closes Codex finding #5 (atomic skill packaging) for Phase 2a.
34 unit assertions covering: stage validation, file-path escape rejection,
permission check, atomic rename, clobber refusal, symlink refusal, project
tier unresolved, idempotent discard, end-to-end happy + simulated test
failure + approval reject paths.

* feat(scrape): /scrape <intent> skill template
One entry point for pulling page data. Three paths under the hood:
1. Match — agent reads $B skill list, semantically matches the user's
intent against each skill's triggers + description + host. Confident
match = $B skill run <name> in ~200ms.
2. Prototype — no match, drive the page with $B goto/text/html/links etc.
Return JSON, append a one-line "say /skillify" nudge.
3. Mutating refusal — verbs like submit/click/fill route to /automate
(Phase 2b P0); /scrape is read-only by contract.
Match decision lives in the agent, not the daemon. No new code in
browse/src/, no expanded daemon command surface, no new prompt-injection
blast radius.

* feat(skillify): /skillify codifies last /scrape into permanent skill
The productivity multiplier. /scrape discovers the flow; /skillify writes
it as deterministic Playwright-via-browse-client code so the next /scrape
on the same intent runs in ~200ms.
11-step flow with three locked contracts from the v1.19.0.0 plan review:
D1 — Provenance guard. Walk back ≤10 agent turns for a clearly-bounded
/scrape result. Refuse with one specific message if cold. No silent
synthesis from chat fragments.
D2 — Synthesis input slice. Extract ONLY the final-attempt $B calls that
produced the JSON the user accepted, plus the user's intent string. Drop
failed selectors, drop unrelated chat, drop earlier-session content.
Closes Codex finding #6 by picking option (b) from the design doc:
re-prompt from agent's own context, not a structured recorder.
D3 — Atomic write. Stage to ~/.gstack/.tmp/skillify-<spawnId>/, run
$B skill test against the temp dir, only rename into the final tier path
on test pass + user approval. Test fail or approval reject = rm -rf the
temp dir entirely.
Default tier: global (~/.gstack/browser-skills/<name>/). --project flag
overrides to per-project. Generated test must include at least one ★★
assertion (parsed JSON has expected shape + non-empty key fields), not a
smoke ★ assertion.
Bun runtime distribution (Codex finding #7) carries over to Phase 4.
Documented in the skill's Limits section.

* test(browser-skills): gate-tier E2E for /scrape + /skillify (D4)
Five scenarios cover the productivity loop and the contracts locked
during the v1.19.0.0 plan review:
scrape-match-path — intent matching bundled hackernews-frontpage
routes via $B skill run, no prototype phase
scrape-prototype-path — no matching skill, drives $B against a local
file:// fixture, returns JSON, suggests
/skillify
skillify-happy-path — /scrape then /skillify; skill written to
~/.gstack/browser-skills/<name>/ with the
full file tree; SKILL.md prose body must
not contain conversation fragments (D2)
skillify-provenance-refusal — cold /skillify with no prior /scrape refuses
with the D1 message; nothing on disk (D1)
skillify-approval-reject — /scrape then /skillify but reject in the
approval gate; temp dir is removed, nothing
at the final tier path (D3)
All five gate-tier (~$0.50-$1.50 each, ~$5 total per CI run). Set EVALS=1
to enable. Uses local file:// fixtures so prototype + skillify scenarios
run deterministically without network.
Touchfiles registers all 5 entries with proper deps on scrape/**,
skillify/**, browse/src/browser-skill-write.ts, and the Phase 1 runtime
modules. The match-path test depends on the bundled hackernews-frontpage
skill so its touchfile includes browser-skills/hackernews-frontpage/**.

* docs(browser-skills): TODOS Phase 2a + design doc D1-D4 decisions
TODOS.md:
- Narrows existing P1 (was "/scrape and /automate") to "/scrape and
/skillify" — the /scrape + /skillify wedge ships in this branch.
Codex finding #6 (synthesis) removed from Cons (resolved by D2);
finding #7 (Bun runtime) stays as the open carry-over.
- Adds new ## P0 above PACING_UPDATES_V0 for the /automate follow-up.
Same skillify pattern as /scrape, different trust profile (per-step
confirmation gate when running non-codified). Reuses /skillify and
the D3 helper as-is. Effort M.
BROWSER_SKILLS_V1.md:
- Phase table re-organized into 1, 2a, 2b, 3, 4. Phase 1 + Phase 2a
consolidate into v1.19.0.0 ship (the v1.16.0.0 branch-internal
bump never landed on main).
- New "Phase 2a" sub-section captures the four decisions locked
during /plan-eng-review:
D1 — provenance guard (≤10 turn walk-back, refuse if cold)
D2 — synthesis input slice (final-attempt $B calls only,
closes Codex finding #6)
D3 — atomic write discipline (temp-dir-then-rename via new
browse/src/browser-skill-write.ts helper)
D4 — full test scope (5 gate E2E + 1 unit + smoke)
- New "Phase 2b" sketch for /automate: same skillify machinery,
per-mutating-step confirmation gate, deferred to next branch.

* release: v1.16.0.0 -> v1.19.0.0 — browser-skills Phase 1 + 2a
Consolidates the v1.16.0.0 branch-internal bump (Phase 1 runtime, never
landed on main) with Phase 2a (/scrape + /skillify + atomic-write helper)
into one v1.19.0.0 ship per CLAUDE.md "Never orphan branch-internal
versions" rule.
Headline: Browser-skills land end-to-end. /scrape <intent> first call
drives the page; second call runs the codified script in 200ms.
The unified CHANGELOG entry covers:
- Phase 1 runtime: $B skill list/show/run/test/rm, scoped tokens,
3-tier storage, bundled hackernews-frontpage reference.
- Phase 2a: /scrape + /skillify gstack skills, browser-skill-write.ts
atomic helper, 5 gate-tier E2E + 34 unit assertions.
Numbers table updated: 5 new modules (+browser-skill-write), 2 new
gstack skills, 6 of 8 Codex outside-voice findings resolved (synthesis
#6 closed by D2; Bun runtime #7 + OS sandbox #1 stay deferred to Phase 4).
/automate (Phase 2b) is split out as P0 in TODOS for the next branch.

* fix(commands): tighten descriptions for LLM-judge baseline pinning
The skill-llm-eval test "baseline score pinning" failed CI on three
retry attempts: judge gave command_reference.actionability=3, baseline
demands ≥4. Judge cited 8 specific gaps in COMMAND_DESCRIPTIONS.
This commit closes 7 of 8 by tightening the descriptions:
- press: documents that key names are case-sensitive Playwright keys,
shows modifier syntax (Shift+Enter, Control+A), links the full key
list. Removes the "is this case-sensitive?" guesswork.
- is: documents that <sel> accepts either a CSS selector OR an @ref
token from a prior snapshot, and that property values are case-
sensitive.
- scroll: documents that there is no --by/--to amount option, points
at `js window.scrollTo(0, N)` for pixel-precise scrolling.
- js / eval: clarifies that both run in the same JS sandbox, the
difference is just inline expr (js) vs file (eval).
- storage: clarifies sessionStorage is read-only via this command,
points at `js sessionStorage.setItem(...)` for the write path.
- chain: walks through how to invoke (pipe a JSON array of arrays to
$B chain), confirms it stops at the first error.
- cdp: explains how to discover allowed methods (read cdp-allowlist.ts)
+ shows a concrete example invocation.
- domain-skill: explains that the "classifier flag" is set automatically
by the L4 prompt-injection scan (agents do not set it manually);
enumerates the full lifecycle verbs.
The 8th gap (storage set syntax conflict) is also resolved as part of
the storage rewrite.
Two pipe-character bugs caught by the existing
`no command description contains pipe character` guard at
`test/gen-skill-docs.test.ts:595`: the chain example originally used
`echo '[...]' | $B chain` (literal pipe) and the cdp description used
`tab|browser` / `trusted|untrusted` (also literal pipes). Both rewritten
to keep markdown table cells intact.
Verification: 696/0 pass on skill-validation + gen-skill-docs after
regen across all hosts. The CI llm-judge eval will re-run against the
new SKILL.md and should hit actionability ≥4 reliably.

* docs(browser): rewrite BROWSER.md as complete reference
Full rewrite covering the gstack browser surface as of v1.19.0.0. Up from
488 to 1,299 lines, 26 top-level sections.
Adds previously-undocumented subsystems:
- The productivity loop: /scrape + /skillify with D1 (provenance guard),
D2 (final-attempt-only synthesis), D3 (atomic-write discipline) contracts.
- Browser-skills runtime: anatomy, three-tier storage, scoped tokens, trust
model (capability + env axes), sibling SDK distribution, atomic-write
helper, bundled hackernews-frontpage reference.
- Domain-skills: per-site agent notes with quarantined → active → global
state machine and the L4-classifier auto-promotion gate.
- Pair-agent: dual-listener architecture, 26-command tunnel allowlist,
canDispatchOverTunnel pure gate, three token types (root, setup key,
scoped), denial log path + salt model.
- Security stack L1-L6: layer table, thresholds (BLOCK/WARN/LOG_ONLY/
SOLO_CONTENT_BLOCK), ensemble rule, classifier model paths, env knobs.
- Side Panel deep dive: Terminal pane (Claude PTY) as the primary surface
with Activity/Refs/Inspector as debug overlays, WS auth via
Sec-WebSocket-Protocol, gstackInjectToTerminal cross-pane plumbing.
- CDP escape hatch: $B cdp deny-default allowlist, $B inspect CSS inspector,
$B ux-audit page structure extraction.
- Meta commands previously undocumented: tabs/frames/state/watch/inbox/
tab-each, with usage and storage paths.
- Authentication: three token types with lifetimes, SSE session cookie,
PTY session cookie, token registry behavior.
- Full source map: 30+ file inventory of browse/src/ vs the old 11-file
list.
Preserves from before: architecture diagram, daemon lifecycle, snapshot
ref staleness, screenshot modes, goto file:// vs load-html semantics,
batch endpoint, JS await wrapping, env vars, performance numbers vs MCP,
Playwright acknowledgments, dev guide.
Cross-links to ARCHITECTURE.md, CLAUDE.md, docs/REMOTE_BROWSER_ACCESS.md,
docs/designs/BROWSER_SKILLS_V1.md, scrape/SKILL.md, skillify/SKILL.md,
TODOS.md so anyone landing on BROWSER.md can navigate to the load-bearing
companion docs.

* fix(server): tab-ownership gate keys on tabPolicy, not isWrite
Browser-skill spawns hit `403: Tab not owned by your agent` on every
first run because the gate at server.ts:639 fired for any non-root
write, regardless of the token's tabPolicy. The bundled
hackernews-frontpage reference skill failed identically. Every
/skillify-generated skill failed identically. The user's natural
tabs have no claimed owner — by design — so any skill driving
them via `goto` (a write) was 403'd.
The intent in skill-token.ts:79 was always correct: `tabPolicy: 'shared'`
with the comment "skill scripts may switch tabs as needed." The
enforcement just ignored it.
Two surgical changes:
browser-manager.ts:checkTabAccess — gate now keys on options.ownOnly
only. Shared-policy tokens (skill spawns, default scoped clients) get
permissive access — root-equivalent for the tab gate. Own-only tokens
(pair-agent over the ngrok tunnel) still require ownership for every
read and write. isWrite stays in the signature for callers that want
to log or branch elsewhere; it no longer gates the decision.
server.ts:639 — gate predicate narrowed from
(WRITE_COMMANDS.has(command) || tokenInfo.tabPolicy === 'own-only')
to just
tokenInfo.tabPolicy === 'own-only'
The 'newtab' exemption stays. Shared tokens skip the gate entirely;
own-only tokens still hit it. Comment block above the gate updated to
document the new predicate intent.
Pair-agent isolation is intact. Tunnel tokens still default to
tabPolicy: 'own-only', still must `newtab` first to get a tab they
can drive, still can't dispatch any of the 23 commands outside the
tunnel allowlist.
The capability gate (scope checks) and rate limits already constrain
what local scoped clients can do; tab ownership was never a security
boundary for them — only for pair-agent. This release makes the
enforcement match the original design intent.

* test(server): lock the shared-vs-own-only tab gate contract
The pre-fix tests at tab-isolation.test.ts:43,57 encoded the broken
behavior as the contract — they specifically asserted "scoped agent
cannot write to unowned tab," which was the exact failure mode that
broke browser-skills. They passed because they tested the wrong
invariant.
This commit replaces those tests with explicit shared-vs-own-only
coverage that documents what each policy actually means:
- Shared scoped agents (skill spawns, default scoped clients) can
read AND write any tab — unowned, their own, or another agent's.
The capability is gated by scope checks + rate limits, not by tab
ownership.
- Own-only scoped agents (pair-agent over tunnel) cannot read OR
write any tab they don't own. Pre-fix this case was conflated with
shared writes; now it's explicit.
9 unit assertions on checkTabAccess, up from 6. Each test names
the policy axis it's covering so a future refactor can't quietly
flip the contract.
Adds source-shape regression test 10a in server-auth.test.ts:
"tab gate predicate is own-only-scoped, not write-scoped." The
gate's `if (...)` line MUST contain `tabPolicy === 'own-only'` and
MUST NOT contain `WRITE_COMMANDS.has(command) ||`. If a future
refactor re-introduces the write-scoped gate, this fails immediately
in free-tier `bun test`.
Updates the marker for the existing newtab-excluded test to match
the new comment block ("Tab ownership check (own-only tokens /
pair-agent isolation)").

* release: v1.19.0.0 -> v1.20.0.0 — fix tab-ownership footgun
Patch release on top of v1.19.0.0. The shipping headline of v1.19.0.0
(/scrape + /skillify productivity loop) was broken on first run in any
session where the daemon already had a tab. Bundled
hackernews-frontpage failed identically. Every /skillify-generated
skill failed identically.
The fix narrows the tab-ownership gate from "any non-root write" to
"tabPolicy === 'own-only' only." Pair-agent isolation (the v1.6.0.0
threat model) is intact; local skill spawns get their original
behavior back.
VERSION: 1.19.0.0 -> 1.20.0.0
package.json version: synced.
CHANGELOG entry leads with the user-visible impact: the productivity
loop works again, no half-second-stalls of confused 403s. Includes
before/after metrics on the bundled reference skill and the broken-
contract pre-fix tests that hid the regression.

* docs(claude): sharpen CHANGELOG rule — diff between main and ship
Codifies what was already implicit in the existing "Never orphan
branch-internal versions" + "Only document what shipped between main
and this change" sections, but with sharper language and concrete
NEVER examples.
The rule: a CHANGELOG entry is the diff between main and the shipping
branch — what users get when they upgrade. NOT how the branch got
there. Branch-internal version bumps, mid-branch bug fixes, plan
review outcomes, and patch narratives all belong in PR descriptions
and commit messages, not in CHANGELOG.
Adds explicit examples of phrasing to NEVER use:
- "v1.X had a bug that v1.Y fixes" (mentions a branch-internal version)
- "The shipping headline of v1.X was broken because..." (apologizes
for never-released state)
- "Pre-fix tests encoded the broken behavior" (contributor's victory
lap, not user benefit)
- "Two surgical edits, both in the dispatch path" (micro-narrative
of the patch)
The constructive replacement: describe the released system as a
property, not as a fix. "Browser-skills run end-to-end with the
expected tab-access semantics." If a property is worth calling out,
document it in the trust-model section, not as a "we fixed X" callout.
Pairs with feedback_no_shame_changelog and
feedback_changelog_harden_against_critics memories — entries should
read as a flex even to a hostile screenshotter, never admit prior
breakage.

* docs(changelog): consolidate v1.20.0.0 as the diff vs main
Rewrites the v1.20.0.0 entry to describe what users get when they
upgrade from main (v1.17.0.0) to this release: browser-skills
end-to-end. Drops all branch-internal narrative — Phase 1 / Phase 2a
labels, the v1.8.0.0 P1 history paragraph, the test-counts-by-phase
split, and the patch micro-narrative for the tab-policy semantics.
The previously-separate v1.19.0.0 entry (a branch-internal version
that never landed on main) collapses into v1.20.0.0 per the
"Never orphan branch-internal versions" rule.
Tab-access policies are now documented as a property of the trust
model: `'shared'` (skill spawns) is permissive, `'own-only'`
(pair-agent over the tunnel) is strict. No "fix" framing, no
mention of an intermediate state where it was broken.
Adds the BROWSER.md rewrite and the new tab-isolation +
server-auth source-shape regression tests to the itemized changes.
The reverse-chronological order remains: v1.20.0.0 → v1.17.0.0 →
v1.16.0.0 → v1.15.0.0 → ... Gaps (v1.18, v1.19) are fine — those
were branch-internal version numbers that never landed.
