fix: community security + stability fixes (wave 1) (#325)

* feat: add /cso skill — OWASP Top 10 + STRIDE security audit

* fix: harden gstack-slug against shell injection via eval

Whitelist safe characters (a-zA-Z0-9._-) in SLUG and BRANCH output
to prevent shell metacharacter injection when used with eval.

Only affects self-hosted git servers with lax naming rules — GitHub
and GitLab enforce safe characters already. Defense-in-depth.

* fix(security): sanitize gstack-slug output against shell injection

The gstack-slug script is consumed via eval $(gstack-slug) throughout
skill templates. If a git remote URL contains shell metacharacters
like $(), backticks, or semicolons, they would be executed by eval.

Fix: strip all characters except [a-zA-Z0-9._-] from both SLUG and
BRANCH before output. This preserves normal values while neutralizing
any injection payload in malicious remote URLs.

Before: eval $(gstack-slug) with remote "foo/bar$(rm -rf /)" → executes rm
After:  eval $(gstack-slug) with remote "foo/bar$(rm -rf /)" → SLUG=foo-barrm-rf-

* fix(security): redact sensitive values in storage command output

The browse `storage` command dumps all localStorage and sessionStorage
as JSON. This can expose tokens, API keys, JWTs, and session credentials
in QA reports and agent transcripts.

Fix: redact values where the key matches sensitive patterns (token,
secret, key, password, auth, jwt, csrf) or the value starts with known
credential prefixes (eyJ for JWT, sk- for Stripe, ghp_ for GitHub, etc.).

Redacted values show length to aid debugging: [REDACTED — 128 chars]

* fix(browse): kill old server before restart to prevent orphaned chromium processes

When the health check fails or the server connection drops, `ensureServer()`
and `sendCommand()` would call `startServer()` without first killing the
previous server process. This left orphaned `chrome-headless-shell` renderer
processes running at ~120% CPU each.

After several reconnect cycles (e.g. pages that crash during hydration or
trigger hard navigations via `window.location.href`), dozens of zombie
chromium processes accumulate and exhaust system resources.

Fix: call `killServer()` on the stale PID before spawning a new server in
both the `ensureServer()` unhealthy path and the `sendCommand()` connection-
lost retry path.

Fixes #294

* Fix YAML linter error: nested mapping in compact sequence entries

Having "Run: bun" inside a plain scalar is not allowed per YAML spec which states: Plain scalars must never contain the “: ” and “ #” character combinations.

This simple fix switches to block scalars (|) to eliminate the ambiguity without changing runtime behavior.

* fix(security): add Azure metadata endpoint to SSRF blocklist

Add metadata.azure.internal to BLOCKED_METADATA_HOSTS alongside the
existing AWS/GCP endpoints. Closes the coverage gap identified in #125.

* test: add coverage for storage redaction

Test key-based redaction (auth_token, api_key), value-based redaction
(JWT prefix, GitHub PAT prefix), pass-through for normal keys, and
length preservation in redacted output.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: add community PR triage process to CONTRIBUTING.md

Document the wave-based PR triage pattern used for batching community
contributions. References PR #205 (v0.8.3) as the original example.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: adjust test key names to avoid redaction pattern collision

Rename testKey→testData and normalKey→displayName in storage tests
to avoid triggering #238's SENSITIVE_KEY regex (which matches 'key').
Also generate Codex variant of /cso skill.

* docs: update project documentation for v0.9.10.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: zero-noise /cso security audits with FP filtering (v0.11.0.0)

Absorb Anthropic's security-review false positive filtering into /cso:
- 17 hard exclusions (DOS, test files, log spoofing, SSRF path-only,
  regex injection, race conditions unless concrete, etc.)
- 9 precedents (React XSS-safe, env vars trusted, client-side code
  doesn't need auth, shell scripts need concrete untrusted input path)
- 8/10 confidence gate — below threshold = don't report
- Independent sub-agent verification for each finding
- Exploit scenario requirement per finding
- Framework-aware analysis (Rails CSRF, React escaping, Angular sanitization)

* docs: consolidate CHANGELOG — merge /cso launch + community wave into v0.11.0.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: rewrite README — lead with Karpathy quote, cut LinkedIn phrases, add /cso

Opens with the revolution (Karpathy, Steinberger/OpenClaw), keeps credentials
and LOC numbers, cuts filler phrases, adds hater bait, restores hiring block,
removes bloated "What's new" section, adds /cso to skills table and install.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(cso): adversarial review fixes — FP filtering, prompt injection, language coverage

- Exclusion #10: test files must verify not imported by non-test code
- Exclusion #13: distinguish user-message AI input from system-prompt injection
- Exclusion #14: ReDoS in user-input regex IS a real CVE class, don't exclude
- Add anti-manipulation rule: ignore audit-influencing instructions in codebase
- Fix confidence gate: remove contradictory 7-8 tier, hard cutoff at 8
- Fix verifier anchoring: send only file+line, not category/description
- Add Go, PHP, Java, C#, Kotlin to grep patterns (was 4 languages, now 8)
- Add GraphQL, gRPC, WebSocket endpoint detection to attack surface mapping

* fix(docs): correct skill counts, add /autoplan to README tables

Skill count was wrong in 3 places (said 19+7=26, said 25, actual is 28).
Added /autoplan to specialist table. Fixed troubleshooting skills list
to include all skills added since v0.7.0.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(browse): DNS rebinding protection for SSRF blocklist

validateNavigationUrl is now async — resolves hostname to IP and checks
against blocked metadata IPs. Prevents DNS rebinding where evil.com
initially resolves to a safe IP, then switches to 169.254.169.254.
All callers updated to await. Tests updated for async assertions.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(browse): lockfile prevents concurrent server start races

Adds exclusive lockfile (O_CREAT|O_EXCL) around ensureServer to prevent
TOCTOU race where two CLI invocations could both kill the old server and
start new ones, leaving an orphaned chromium process. Second caller now
waits for the first to finish starting.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(browse): improve storage redaction — word-boundary keys + more value prefixes

Key regex: use underscore/dot/hyphen boundaries instead of \b (which treats
_ as word char). Now correctly redacts auth_token, session_token while
skipping keyboardShortcuts, monkeyPatch, primaryKey.

Value regex: add AWS (AKIA), Stripe (sk_live_, pk_live_), Anthropic (sk-ant-),
Google (AIza), Sendgrid (SG.), Supabase (sbp_) prefixes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: migrate all remaining eval callers to source, fix stale CHANGELOG claim

5 templates and 2 bin scripts still used eval $(gstack-slug). All now use
source <(gstack-slug). Updated gstack-slug comment to match. Fixed v0.8.3
CHANGELOG entry that falsely claimed eval was fully eliminated — it was
the output sanitization that made it safe, not a calling convention change.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(docs): add /autoplan to install instructions, regen skill docs

The install instruction blocks and troubleshooting section were missing
/autoplan. All three skill list locations now include the complete 28-skill
set. Regenerated codex/agents SKILL.md files to match template changes.

* docs: update project documentation for v0.11.0.0

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs(cso): add disclaimer — not a substitute for professional security audits

LLMs can miss subtle vulns and produce false negatives. For production
systems with sensitive data, hire a real firm. /cso is a first pass,
not your only line of defense. Disclaimer appended to every report.

fix: Windows support — Node.js server fallback for Playwright (#255)

* fix: Windows support — Node.js server fallback for Playwright

Setup hangs on Windows 11 because Bun's child_process can't handle
Playwright's --remote-debugging-pipe (fd 3/4 pipe handles). Fall back
to Node.js on Windows for both the setup verification and server
runtime. macOS/Linux completely unaffected — all Windows code behind
IS_WINDOWS / process.platform === 'win32' guards.

Based on community PR #194 by @sozairali. Fixed sed -i portability
(perl -pi -e) in build-node-server.sh for macOS compatibility.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: cross-platform path handling for Windows compatibility

Replace hardcoded '/tmp' and 'dir + "/"' path checks with
platform-aware constants from new platform.ts module. On macOS/Linux
this evaluates identically ('/tmp', '/'); on Windows it uses
os.tmpdir() and path.sep. Zero behavior change on Unix.

feat: multi-agent support — gstack works on Codex, Gemini CLI, and Cursor (v0.9.0) (#226)

* refactor: host-aware gen-skill-docs + --host codex generation

Refactor gen-skill-docs.ts for multi-agent support:
- Add Host type, HostPaths interface, HOST_PATHS config
- Decompose generatePreamble() into 7 composable sub-functions
- Replace all hardcoded .claude/skills/gstack paths with ctx.paths
- Replace static findTemplates() list with dynamic filesystem scan
- Add --host codex|agents flag (aliases, same output)
- Add processTemplate host routing to .agents/skills/gstack-*/
- Add codexSkillName() with double-prefix prevention
- Add transformFrontmatter() — keeps only name + description for Codex
- Add extractHookSafetyProse() — converts hooks to inline advisory
- Add body text path rewriting for remaining hardcoded paths
- Exclude /codex skill from Codex generation (self-referential)

Claude output is unchanged (verified via --dry-run).
SKILL.md is an open standard: .agents/skills/ works on Codex, Gemini CLI, and Cursor.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: generate Codex/Gemini/Cursor skills into .agents/skills/

Generated 21 skill files for the open SKILL.md standard:
- Output: .agents/skills/gstack-*/SKILL.md (one per skill)
- Frontmatter: name + description only (no allowed-tools/version)
- No .claude/skills/ paths in any generated file
- /codex skill excluded (Claude wrapper, self-referential on Codex)
- Hook skills (careful/freeze/guard) get inline safety prose
- Build script generates both hosts: bun run build

Supported agents (all read .agents/skills/):
- Codex CLI
- Gemini CLI
- Cursor

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: dual-host setup + find-browse for Codex/Gemini/Cursor

- setup: add --host codex|claude|auto flag, install to ~/.codex/skills/
  when targeting Codex, auto-detect installed agents
- find-browse: priority chain .codex > .agents > .claude (both
  workspace-local and global)
- dev-setup/teardown: create .agents/skills/gstack symlinks for dev mode

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: Codex generation tests + CI + docs for multi-agent support

Tests (28 new):
- Codex output path routing, frontmatter validation (name+description only)
- No .claude/skills/ path leaks in Codex output (regression guard)
- /codex skill exclusion, hook→prose conversion, multiline YAML
- --host agents alias, dynamic template discovery
- Codex skill validation + $B command validation
- find-browse priority chain verification
- Replace static ALL_SKILLS list with dynamic filesystem scan

CI:
- Add Codex freshness check to skill-docs workflow

Docs:
- AGENTS.md: Codex-facing project instructions
- README: multi-agent installation section
- CONTRIBUTING: dual-host development workflow
- CHANGELOG: v0.9.0 multi-agent support entry

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: Codex E2E test harness — verify skills work on Codex CLI

New test infrastructure:
- CodexSessionRunner: spawns codex exec, parses JSONL stream, returns
  structured results (output, reasoning, toolCalls, tokens)
- JSONL parser ported from Python (codex/SKILL.md.tmpl) to TypeScript
- Temp HOME skill installation for Codex discovery testing

E2E tests (gated behind EVALS=1 + codex + OPENAI_API_KEY):
- codex-discover-skill: installs skill, verifies Codex finds it
- codex-review-findings: runs gstack-review via Codex, validates output

Integrates with existing eval infrastructure:
- Diff-based test selection via touchfiles
- Eval persistence via EvalCollector
- bun run test:codex / test:codex:all convenience scripts

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: bump VERSION to 0.9.0 to match CHANGELOG

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: Codex sidecar paths + setup installs generated skills

Two bugs found by Codex adversarial review:

1. Sidecar path mismatch: generated Codex skills referenced
   .agents/skills/gstack-review/checklist.md but setup creates
   sidecars at .agents/skills/gstack/review/. Fixed path rewriter
   to emit .agents/skills/gstack/review/ (matching setup layout).

2. Setup installed Claude-format source dirs for Codex global
   install instead of the generated Codex-format skills. Split
   link_skill_dirs into link_claude_skill_dirs (source dirs for
   Claude) and link_codex_skill_dirs (generated .agents/skills/
   gstack-* dirs for Codex).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: comprehensive Codex path rewriting + setup install tests

17 new tests covering:
- Sidecar path rewriting: .claude/skills/review → .agents/skills/gstack/review/
  (catches the bug where checklist.md was unreachable at gstack-review/)
- All 4 path rewrite rules tested individually across all skills
- Greptile triage sidecar path correctness
- Ship skill sidecar paths for pre-landing review
- Claude output regression guard: zero Codex paths in any Claude skill
- Setup script validation: separate link functions for Claude vs Codex,
  link_codex_skill_dirs reads from .agents/skills/, create_agents_sidecar
  links runtime assets (bin, browse, review, qa)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: regenerate Codex skills after investigate rename merge

Remove stale gstack-debug, add gstack-investigate, regenerate all
Codex skills to pick up changes merged from main (investigate rename,
platform-agnostic templates, review helpers).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: Codex E2E uses ~/.codex/ auth, not OPENAI_API_KEY

- Remove OPENAI_API_KEY gate from test prerequisites
- Copy real ~/.codex/ auth config into temp HOME so codex can authenticate
- Increase review test timeout to 540s (codex does thorough 60+ tool call reviews)
- Document in CLAUDE.md that Codex uses its own auth config

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

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* 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

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* 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

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* 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.

fix: js statement wrapping + click auto-routes option to selectOption (v0.4.5) (#117)

* 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."

UP_TO_DATE cache now expires after 60 min (was 720 min / 12 hours).
UPGRADE_AVAILABLE keeps 720 min TTL to keep nagging.

feat: await support in browse js/eval + contributor mode v2 (#104)

* feat: support await in $B js and eval commands

Auto-wrap await expressions in async IIFE context so
$B js "await fetch(...)" works without SyntaxError.

- hasAwait() strips comments before detection
- js: expression wrapping (async()=>(expr))()
- eval: smart wrapping — single-line=expression, multi-line=block
- 6 new unit tests covering async, false-positive, and return semantics

* feat: redesign contributor mode — periodic reflection with 0-10 rating

Replace passive "report when things break" with active reflection:
- Rate gstack experience 0-10 at workflow step boundaries
- Historical calibration example (await bug) anchors the reporting bar
- "What would make this a 10" field focuses on actionable improvements
- Removed category lists in favor of judgment-based assessment

* test: add deterministic contributor mode preamble validation

40 new skill-validation tests (4 checks × 10 skills) verify:
- 0-10 rating scale present
- Calibration example present
- "What would make this a 10" field present
- Periodic reflection (not per-command)

Update existing E2E contributor eval for new report format.

* chore: bump version and changelog (v0.4.2)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: improve contributor mode + qa-quick E2E reliability

Contributor mode:
- Add "do not truncate" directive to template — agent was stopping
  after "My rating" without completing Steps/Raw output/What would
  make this a 10 sections
- Restore assertions for Steps to reproduce and Date footer

QA quick:
- Make test server URL prominent: top of prompt, explicit "already
  running" and "do NOT discover ports" instructions
- Bump session timeout 180s→240s and test timeout 240s→300s
- Set B= at top of prompt (was buried in prose)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: use flexible assertions for contributor mode E2E

Agent writes thorough reports with creative section names
("Repro Steps" vs "Steps to reproduce"). Match intent not formatting:
- /repro|steps to reproduce/ for reproduction steps
- /date.*2026/ for date footer presence

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: add E2E eval failure blame protocol

"Not related to our changes" is an extraordinary claim that requires
extraordinary proof. When evals fail during /ship:

1. Run the same eval on main — prove it fails there too
2. If it passes on main, it IS your change — trace the blame
3. If you can't verify, say "unverified" not "pre-existing"

Added to CLAUDE.md and as a comment in skill-e2e.test.ts.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update CONTRIBUTING.md and BROWSER.md for v0.4.2

CONTRIBUTING.md: update contributor mode description — now describes
periodic 0-10 reflection loop instead of passive friction detection.

BROWSER.md: add js/eval async documentation — await expressions are
auto-wrapped in async context, single-line eval returns values directly.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: restore v0.4.2 changelog entries lost during cherry-pick conflict

The base branch detection entries from main were dropped when resolving
the CHANGELOG conflict — should have merged both sets, not replaced.

feat: smart update check with auto-upgrade, snooze backoff, config CLI (v0.3.9) (#62)

* feat: add bin/gstack-config CLI for reading/writing ~/.gstack/config.yaml

Simple get/set/list interface for persistent gstack configuration.
Used by update-check and upgrade skill for auto_upgrade and update_check settings.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: smart update check with 12h cache, snooze backoff, config disable

- Reduce cache TTL from 24h to 12h for faster update detection
- Add exponential snooze backoff: 24h → 48h → 1 week (resets on new version)
- Add update_check: false config option to disable checks entirely
- Clear snooze file on just-upgraded
- 14 new tests covering snooze levels, expiry, corruption, and config paths

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: upgrade skill with auto-upgrade, 4-option prompt, vendored sync

- Auto-upgrade mode via config or GSTACK_AUTO_UPGRADE=1 env var
- 4-option AskUserQuestion: upgrade once, always, not now, never
- Step 4.5: sync local vendored copy after upgrading primary install
- Snooze write with escalating backoff on "Not now"
- Update preamble text in gen-skill-docs for new upgrade flow
- Regenerate all SKILL.md files

feat: TODOS-aware skills, 2-tier Greptile replies, gitignore fix (#61)

* fix: log non-ENOENT errors in ensureStateDir() instead of silently swallowing

Replace bare catch {} with ENOENT-only silence. Non-ENOENT errors (EACCES,
ENOSPC) are now logged to .gstack/browse-server.log. Includes test for
permission-denied scenario with chmod 444.

* feat: merge TODO.md + TODOS.md into unified backlog with shared format reference

Merge TODO.md (roadmap) and TODOS.md (near-term) into one file organized by
skill/component with P0-P4 priority ordering and Completed section. Add shared
review/TODOS-format.md for canonical format. Add static validation tests.

* feat: add 2-tier Greptile reply system with escalation detection

Add reply templates (Tier 1 friendly, Tier 2 firm), explicit escalation
detection algorithm, and severity re-ranking guidance to greptile-triage.md.

* feat: cross-skill TODOS awareness + Greptile template refs in all skills

/ship Step 5.5: auto-detect completed TODOs, offer reorganization.
/review Step 5.5: cross-reference PR against open TODOs.
/plan-ceo-review, /plan-eng-review: TODOS context in planning.
/retro: Backlog Health metric. /qa: bug TODO context in diff-aware mode.
All Greptile-aware skills now reference reply templates and escalation detection.

* chore: bump version and changelog (v0.3.8)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update CONTRIBUTING.md for v0.3.8 changes

Clarify test tier cost table (Tier 3 standalone vs combined), add TODOS.md
to "Things to know", mention Greptile triage in ship workflow description.

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.

* chore: bump version and changelog (v0.3.7)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: add screenshot modes to BROWSER.md command reference

Merge pull request #55 from garrytan/v0.3.6-qa-upgrades

feat: E2E observability + eval infrastructure + all skills templated
baf8acd5 — Garry Tan a month ago
fix: update check ignores stale UP_TO_DATE cache after version change

The UP_TO_DATE cache path exited immediately without checking if the
cached version still matched the local VERSION. After upgrading (e.g.
0.3.3 → 0.3.4), the cache still said "UP_TO_DATE 0.3.3" and the
script never re-checked against remote — so updates were invisible
until the 24h cache expired.

Now both UP_TO_DATE and UPGRADE_AVAILABLE verify cached version vs
local before trusting the cache.

test: add update-check exit code regression tests

Guards against the "exits 1 when up to date" bug that broke skill
preambles. Two new tests: real VERSION + unreachable remote, and
multi-call sequence verifying exit 0 in all states.

feat: 3-tier eval suite with planted-bug outcome testing (EVALS=1)

Adds comprehensive eval infrastructure:
- Tier 1 (free): 13 new static tests — cross-skill path consistency, QA
  structure validation, greptile format, planted-bug fixture validation
- Tier 2 (Agent SDK E2E): /qa quick, /review with pre-built git repo,
  3 planted-bug outcome evals (static, SPA, checkout — each with 5 bugs)
- Tier 3 (LLM judge): QA workflow quality, health rubric clarity,
  cross-skill consistency, baseline score pinning

New fixtures: 3 HTML pages with 15 total planted bugs, ground truth JSON,
review-eval-vuln.rb, eval-baselines.json. Shared llm-judge.ts helper (DRY).

Unified EVALS=1 flag replaces SKILL_E2E + ANTHROPIC_API_KEY checks.
`bun run test:evals` runs everything that costs money (~$4/run).

feat: daily update check + /gstack-upgrade skill (v0.3.4) (#42)

* feat: add daily update check script + /gstack-upgrade skill

bin/gstack-update-check: pure bash, checks VERSION against remote once/day,
outputs UPGRADE_AVAILABLE or JUST_UPGRADED. Uses ~/.gstack/ for state.

gstack-upgrade/SKILL.md: new skill with inline upgrade flow for all preambles.
Detects global-git, local-git, vendored installs. Shows What's New from CHANGELOG.

browse/test/gstack-update-check.test.ts: 10 test cases covering all branch paths.

* refactor: remove version check from find-browse, simplify to binary locator

Delete checkVersion(), readCache(), writeCache(), fetchRemoteSHA(),
resolveSkillDir(), CacheEntry interface, REPO_URL/CACHE_PATH/CACHE_TTL
constants, and META output from find-browse.ts.

Version checking is now handled by bin/gstack-update-check (previous commit).

* feat: add update check preamble to all 9 skills

Every skill now runs bin/gstack-update-check on invocation. If an upgrade
is available, reads gstack-upgrade/SKILL.md inline upgrade flow.

Also adds AskUserQuestion to 5 skills that lacked it (gstack root, browse,
qa, retro, setup-browser-cookies) and Bash to plan-eng-review.

Simplifies qa and setup-browser-cookies setup blocks (removes META parsing).

* chore: bump version and changelog (v0.3.4)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: remove unused import + add corrupt cache test

Address pre-landing review findings:
- Remove unused mkdirSync import from gstack-update-check.test.ts
- Add Path I test: corrupt cache file falls through to remote fetch

feat: add remote slug helper and auto-gitignore for .gstack/

- getRemoteSlug() in config.ts: parses git remote origin → owner-repo format
- browse/bin/remote-slug: shell helper for SKILL.md use (BSD sed compatible)
- ensureStateDir() now appends .gstack/ to project .gitignore if not present
- setup creates ~/.gstack/projects/ global state directory
- 7 new tests: 4 gitignore behavior + 3 remote slug parsing

feat: v0.3.2 — project-local state, diff-aware QA, Greptile integration (#36)

* 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

* chore: clean up .bun-build temp files after compile

bun build --compile leaves ~58MB temp files in the working directory.
Add rm -f .*.bun-build to the build script to clean up after each build.

* fix: make help command reachable by removing it from META_COMMANDS

help was in META_COMMANDS, so it dispatched to handleMetaCommand() which
threw "Unknown meta command: help". Removing it from the set lets the
dedicated else-if handler in handleCommand() execute correctly.

* chore: bump version and changelog (v0.3.2)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* 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.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: narrow gitignore to .claude/skills/ instead of all .claude/

Avoids ignoring legitimate Claude Code config like settings.json or CLAUDE.md.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: rename DEVELOPING_GSTACK.md to CONTRIBUTING.md

Rewritten as a contributor-friendly guide instead of a dry plan doc.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: explain why dev-setup is needed in CONTRIBUTING.md quick start

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: add browser interaction guidance to CLAUDE.md

Prevents Claude from using mcp__claude-in-chrome__* tools instead of /browse.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* 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.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: update crash log path reference to .gstack/

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* test: add config tests and update CLI lifecycle test

14 new tests for config resolution, ensureStateDir, readVersionHash,
resolveServerScript, and version mismatch detection. Remove obsolete
CONDUCTOR_PORT/BROWSE_PORT filtering from commands.test.ts.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update BROWSER.md and TODO.md for project-local state

Replace /tmp paths with .gstack/, remove CONDUCTOR_PORT docs, document
random port selection and per-project isolation. Add server bundling TODO.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: update README, CHANGELOG, and CONTRIBUTING for v0.3.2

- README: replace Conductor-aware language with project-local isolation,
  add Greptile setup note
- CHANGELOG: comprehensive v0.3.2 entry with all state management changes
- CONTRIBUTING: add instructions for testing branches in other repos

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: add diff-aware mode to /qa — auto-tests affected pages from branch diff

When on a feature branch, /qa now reads git diff main, identifies affected
pages/routes from changed files, and tests them automatically. No URL required.
The most natural flow: write code, /ship, /qa.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* chore: update CHANGELOG for complete v0.3.2 coverage

Add missing entries: diff-aware QA mode, Greptile integration,
local dev mode, crash log path fix, README/SKILL.md updates.
