fix: security hardening + issue triage (v0.8.3) (#205)
* fix: check for bun before running setup (#147)
Users without bun installed got a cryptic "command not found" error.
Now prints a clear message with install instructions.
Closes #147

* 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.
Closes #17

* 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
shell injection surface. Also hardens gstack-diff-scope usage.
Closes #133
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* fix: rename /debug to /investigate to avoid Claude Code conflict (#190)
Claude Code has a built-in /debug command that shadows the gstack skill.
Renaming to /investigate which better reflects the systematic root-cause
investigation methodology.
Closes #190

* test: add unit tests for path validation helpers
validateOutputPath() and validateReadPath() are security-critical
functions with zero test coverage. Adds 14 tests covering safe paths,
traversal attacks, and prefix collision edge cases.

* chore: bump version and changelog (v0.8.3)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* docs: update /debug → /investigate references in docs
CLAUDE.md, README.md, and docs/skills.md still referenced the old
/debug skill name after the rename.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* 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 (v0.7.4) (#201)
* 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.
Update State Persistence TODO noting saveState/restoreState reusability.
* chore: bump version and changelog (v0.7.4)

Merge pull request #128 from xr843/fix/chain-duplication-and-flush-perf
fix: eliminate duplicate command sets in chain, improve flush perf and type safety
fix: eliminate duplicate command sets in chain, improve flush perf and type safety
- 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().

feat: QA restructure, browser ref staleness, eval efficiency metrics (v0.4.0) (#83)
* feat: browser ref staleness detection via async count() validation
resolveRef() now checks element count to detect stale refs after page
mutations (e.g. SPA navigation). RefEntry stores role+name metadata
for better diagnostics. 3 new snapshot tests for staleness detection.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: qa-only skill, qa fix loop, plan-to-QA artifact flow
Add /qa-only (report-only, Edit tool blocked), restructure /qa with
find-fix-verify cycle, add {{QA_METHODOLOGY}} DRY placeholder for
shared methodology. /plan-eng-review now writes test-plan artifacts
to ~/.gstack/projects/<slug>/ for QA consumption.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat: eval efficiency metrics — turns, duration, commentary across all surfaces
Add generateCommentary() for natural-language delta interpretation,
per-test turns/duration in comparison and summary output, judgePassed
unit tests, 3 new E2E tests (qa-only, qa fix loop, plan artifact).

feat: screenshot element/region clipping (v0.3.7) (#56)
* feat: screenshot element/region clipping (--clip, --viewport, CSS/@ref)
Add element crop (CSS selector or @ref), region clip (--clip x,y,w,h),
and viewport-only (--viewport) modes to the screenshot command. Uses
Playwright's native locator.screenshot() and page.screenshot({ clip }).
Full page remains the default. Includes 10 new tests covering all modes
and error paths.

- 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

* 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.

* Bump to v0.3.0 — Phase 2 + Phase 3 changelog
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* 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

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.

* security: redact sensitive values from command output (PR #21)
type no longer echoes text (reports character count), cookie redacts
value with ****, header redacts Authorization/Cookie/X-API-Key/X-Auth-Token,
storage set drops value, forms redacts password fields. Prevents secrets
from persisting in LLM transcripts. 7 new tests.

* security: path traversal prevention for screenshot/pdf/eval (PR #26)
Add validateOutputPath() for screenshot/pdf/responsive (restricts to
/tmp and cwd) and validateReadPath() for eval (blocks .. sequences and
absolute paths outside safe dirs). 7 new tests.
