Hardened shutdown/crash behavior:
- Browser disconnect exits with code 2 (distinct from crash code 1)
- emergencyCleanup kills agent subprocess and saves session state
- Clean shutdown saves session before exit (chat history persists)
- Clear user message on browser disconnect: "Run $B connect to reconnect"

The addInitScript indicator and the extension's content script were both
injecting bottom-right pills, causing duplicates. Remove the pill from
addInitScript (extension handles it). Replace --restore-last-session with
--hide-crash-restore-bubble to suppress the "Chromium didn't shut down
correctly" dialog.

Playwright's chromium.launch() silently ignores --load-extension.
Switch to launchPersistentContext with ignoreDefaultArgs to remove
--disable-extensions flag. Use bundled Chromium (real Chrome blocks
unpacked extensions). Fixed port 34567 for CDP mode so the extension
auto-connects.

Extension auto-loads via --load-extension flag — no manual chrome://extensions
install needed. findExtensionPath() checks repo root, global install, and dev
paths. Also adds bin/gstack-extension helper for manual install in regular
Chrome, and rewrites BROWSER.md install docs with auto-load as primary path.

Replace crude green border + label with polished indicator:
- 2px shimmer gradient at top edge (green→cyan→green, 3s loop)
- Floating pill bottom-right with frosted glass bg, fades to 25%
opacity after 4s so it doesn't compete with page content
- prefers-reduced-motion disables shimmer animation
- Much more subtle — looks like a developer tool, not broken CSS

Injects a 2px green border and small "gstack" label on every page
loaded in the controlled Chrome window via context.addInitScript().
Users can instantly tell which Chrome window Claude controls.
Also fixes close() for channel:chrome mode (uses browser.close()
not browser.disconnect() which doesn't exist).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Playwright's connectOverCDP hangs with Chrome 146 due to CDP protocol
version mismatch. Switch to channel:'chrome' which uses Playwright's
native pipe protocol to launch the system Chrome binary directly.
This is simpler and more reliable:
- No CDP port discovery needed
- No --remote-debugging-port or --user-data-dir hassles
- $B connect just works — launches real Chrome headed window
- All Playwright APIs (snapshot, click, fill) work unchanged
bin/chrome-cdp updated with symlinked profile approach (kept for
manual CDP use cases, but $B connect no longer needs it).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add `connectCDP()` to BrowserManager: connects to a running browser via
Chrome DevTools Protocol. All existing browse commands work unchanged
through Playwright's abstraction layer.
- chrome-launcher.ts: browser discovery, CDP probe, auto-relaunch with rollback
- browser-manager.ts: connectCDP(), mode guards (close/closeTab/recreateContext/handoff),
auto-reconnect on browser restart, getRefMap() for extension API
- server.ts: CDP branch in start(), /health gains mode field, /refs endpoint,
idle timer only resets on /command (not passive endpoints)

* fix: block SSRF via URL validation in browse commands (#17)
Adds validateNavigationUrl() that blocks non-HTTP(S) schemes (file://,
javascript:, data:) and cloud metadata endpoints (169.254.169.254,
metadata.google.internal). Applied to goto, diff, and newTab commands.
Localhost and private IPs remain allowed for local dev QA.

* fix: replace eval $(gstack-slug) with source <(...) (#133)
Eliminates unnecessary use of eval across all skill templates and
generated files. source <(...) has identical behavior without the

* fix: harden URL validation against hostname bypasses (Codex P1)
Codex review found that metadata IPs could be reached via hex
(0xA9FEA9FE), decimal (2852039166), octal, trailing dot, and IPv6
bracket forms. Now normalizes hostnames before checking the blocklist
and probes numeric IP representations via URL constructor.
Also moves URL validation before page allocation in newTab() to
prevent zombie tabs on rejection (Codex P3).
5 new test cases for bypass variants.

* feat: browse handoff — headless-to-headed browser switching
Add `handoff` and `resume` commands that let users take over a visible
Chrome when the headless browser gets stuck (CAPTCHAs, auth walls, MFA).
Architecture: launch-first-close-second for safe rollback. State transfer
via extracted saveState()/restoreState() helpers (DRY with recreateContext).
Auto-handoff hint after 3 consecutive command failures.
* test: handoff unit + integration tests (15 tests)
Covers saveState/restoreState, failure tracking, edge cases (already
headed, resume without handoff), and full integration flow with cookie
and tab preservation across headless-to-headed switch.
* docs: handoff section in browse template + TODOS update
Add User Handoff section to browse/SKILL.md.tmpl with usage examples.

- Remove duplicate CHAIN_READ/CHAIN_WRITE/CHAIN_META sets from meta-commands.ts
and import from commands.ts (single source of truth). The duplicated sets would
silently fail to route new commands added to commands.ts.
- Replace read+concat+write log flush with fs.appendFileSync — O(new entries)
instead of O(total log size) per flush cycle.
- Replace `any` types for contextOptions with Playwright's BrowserContextOptions
and add proper types for storage state in recreateContext().

* fix: js statement wrapping + click auto-routes option to selectOption
Bug 1: js command wrapped all code as expressions — const, semicolons,
and multi-line code broke with SyntaxError. Added needsBlockWrapper()
and wrapForEvaluate() helpers (shared with eval) to detect statements
and use block wrapper {…} instead of expression wrapper (…).
Bug 2: clicking <option> refs hung forever because Playwright can't
.click() native select UI. Click handler now checks ARIA role + DOM
tagName and auto-routes to selectOption() via parent <select>.
Bug 3: click timeouts on <option> elements gave no guidance. Now
throws helpful error: "Use browse select instead of click."

* feat: qa-only skill, qa fix loop, plan-to-QA artifact flow
Add /qa-only (report-only, Edit tool blocked), restructure /qa with

* fix: cookie import picker returns JSON instead of HTML
jsonResponse() was defined at module scope but referenced `url` which
only existed as a parameter of handleCookiePickerRoute(). Every API call
crashed, the catch block also crashed, and Bun returned a default HTML
page that the frontend couldn't parse as JSON.
Thread port via corsOrigin() helper and options objects. Add route-level
tests to prevent this class of bug from shipping again.

* feat: add help command to browse server
Agents that don't have SKILL.md loaded (or misread flags) had no way to
self-discover the CLI. The help command returns a formatted reference of
all commands and snapshot flags.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: version-aware find-browse with META signal protocol
Agents in other workspaces found stale browse binaries that were missing
newer flags. find-browse now compares the local binary's git SHA against
origin/main via git ls-remote (4hr cache), and emits META:UPDATE_AVAILABLE
when behind. SKILL.md setup checks parse META signals and prompt the user
to update.
- New compiled binary: browse/dist/find-browse (TypeScript, testable)
- Bash shim at browse/bin/find-browse delegates to compiled binary
- .version file written at build time with git commit SHA
- Build script compiles both browse and find-browse binaries
- Graceful degradation: offline, missing .version, corrupt cache all skip check

* feat: add shared Greptile comment triage reference doc
Shared reference for fetching, filtering, and classifying Greptile
review comments on GitHub PRs. Used by both /review and /ship skills.
Includes parallel API fetching, suppressions check, classification
logic, reply APIs, and history file writes.
* feat: make /review and /ship Greptile-aware
/review: Step 2.5 fetches and classifies Greptile comments, Step 5
resolves them with AskUserQuestion for valid issues and false positives.
/ship: Step 3.75 triages Greptile comments between pre-landing review
and version bump. Adds Greptile Review section to PR body in Step 8.
Re-runs tests if any Greptile fixes are applied.
* feat: add Greptile batting average to /retro
Reads ~/.gstack/greptile-history.md, computes signal ratio
(valid catches vs false positives), includes in metrics table,
JSON snapshot, and Code Quality Signals narrative.
* docs: add Greptile integration section to README
Personal endorsement, two-layer review narrative, full UX walkthrough
transcript, skills table updates. Add Greptile training feedback loop
to TODO.md future ideas.
* feat: add local dev mode for testing skills from within the repo
bin/dev-setup creates .claude/skills/gstack symlink to the working tree
so Claude Code discovers skills locally. bin/dev-teardown cleans up.
DEVELOPING_GSTACK.md documents the workflow.

* feat: add shared config module for project-local browse state
Centralizes path resolution (git root detection, state dir, log paths) into
config.ts. Both cli.ts and server.ts import from it, eliminating duplicated
PORT_OFFSET/BROWSE_PORT/STATE_FILE logic.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: rewrite port selection to use random ports
Replace CONDUCTOR_PORT magic offset and 9400-9409 scan with random port
10000-60000. Atomic state file writes, log paths from config module,
binaryVersion field for auto-restart on update.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: move browse state from /tmp to project-local .gstack/
CLI now uses config module for state paths, passes BROWSE_STATE_FILE to
spawned server. Adds version mismatch auto-restart, legacy /tmp cleanup
with PID verification, and removes stale global install fallback.

* Phase 2: Enhanced browser — dialog handling, upload, state checks, snapshots
- CircularBuffer O(1) ring buffer for console/network/dialog (was O(n) array+shift)
- Async buffer flush with Bun.write() (was appendFileSync)
- Dialog auto-accept/dismiss with buffer + prompt text support
- File upload command (upload <sel> <file...>)
- Element state checks (is visible/hidden/enabled/disabled/checked/editable/focused)
- Annotated screenshots with ref labels overlaid (-a flag)
- Snapshot diffing against previous snapshot (-D flag)
- Cursor-interactive element scan for non-ARIA clickables (-C flag)
- Snapshot scoping depth limit (-d N flag)
- Health check with page.evaluate + 2s timeout
- Playwright error wrapping — actionable messages for AI agents
- Fix useragent — context recreation preserves cookies/storage/URLs
- wait --networkidle / --load / --domcontentloaded flags
- console --errors filter (error + warning only)
- cookie-import <json-file> with auto-fill domain from page URL
- 166 integration tests (was ~63)

* Phase 2: Rewrite SKILL.md as QA playbook + command reference
Reorient SKILL.md files from raw command reference to QA-first playbook
with 10 workflow patterns (test user flows, verify deployments, dogfood
features, responsive layouts, file upload, forms, dialogs, compare pages).
Compact command reference tables at the bottom.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Phase 3: /qa skill — systematic QA testing with health scores
New /qa skill for systematic web app QA testing. Three modes:
- full: 5-10 documented issues with screenshots and repro steps
- quick: 30-second smoke test with health score
- regression: compare against saved baseline
Includes issue taxonomy (7 categories, 4 severity levels), structured
report template, health score rubric (weighted across 7 categories),
framework detection guidance (Next.js, Rails, WordPress, SPA).
Also adds browse/bin/find-browse (DRY binary discovery using git
rev-parse), .gstack/ to .gitignore, and updated TODO roadmap.

* feat: cookie-import-browser — Chromium cookie decryption module + tests
Pure logic module for reading and decrypting cookies from macOS Chromium
browsers (Comet, Chrome, Arc, Brave, Edge). Supports v10 AES-128-CBC
encryption with macOS Keychain access, PBKDF2 key derivation, and
per-browser key caching. 18 unit tests with encrypted cookie fixtures.
* feat: cookie picker web UI + route handler
Two-panel dark-theme picker served from the browse server. Left panel
shows source browser domains with search and import buttons. Right panel
shows imported domains with trash buttons. No cookie values exposed.
6 API endpoints, importedDomains Set tracking, inline clearCookies.
* feat: wire cookie-import-browser into browse server
Add cookie-picker route dispatch (no auth, localhost-only), add
cookie-import-browser to WRITE_COMMANDS and CHAIN_WRITE, add serverPort
property to BrowserManager, add write command with two modes (picker UI
vs --domain direct import), update CLI help text.
