#Changelog

#0.3.3 — 2026-03-13

#Added

• SKILL.md template system — .tmpl files with {{COMMAND_REFERENCE}} and {{SNAPSHOT_FLAGS}} placeholders, auto-generated from source code at build time. Structurally prevents command drift between docs and code.
• Command registry (browse/src/commands.ts) — single source of truth for all browse commands with categories and enriched descriptions. Zero side effects, safe to import from build scripts and tests.
• Snapshot flags metadata (SNAPSHOT_FLAGS array in browse/src/snapshot.ts) — metadata-driven parser replaces hand-coded switch/case. Adding a flag in one place updates the parser, docs, and tests.
• Tier 1 static validation — 43 tests: parses $B commands from SKILL.md code blocks, validates against command registry and snapshot flag metadata
• Tier 2 E2E tests via Agent SDK — spawns real Claude sessions, runs skills, scans for browse errors. Gated by SKILL_E2E=1 env var (~$0.50/run)
• Tier 3 LLM-as-judge evals — Haiku scores generated docs on clarity/completeness/actionability (threshold ≥4/5), plus regression test vs hand-maintained baseline. Gated by ANTHROPIC_API_KEY
• bun run skill:check — health dashboard showing all skills, command counts, validation status, template freshness
• bun run dev:skill — watch mode that regenerates and validates SKILL.md on every template or source file change
• CI workflow (.github/workflows/skill-docs.yml) — runs gen:skill-docs on push/PR, fails if generated output differs from committed files
• bun run gen:skill-docs script for manual regeneration
• bun run test:eval for LLM-as-judge evals
• test/helpers/skill-parser.ts — extracts and validates $B commands from Markdown
• test/helpers/session-runner.ts — Agent SDK wrapper with error pattern scanning and transcript saving
• ARCHITECTURE.md — design decisions document covering daemon model, security, ref system, logging, crash recovery
• Conductor integration (conductor.json) — lifecycle hooks for workspace setup/teardown
• .env propagation — bin/dev-setup copies .env from main worktree into Conductor workspaces automatically
• .env.example template for API key configuration

#Changed

• Build now runs gen:skill-docs before compiling binaries
• parseSnapshotArgs is metadata-driven (iterates SNAPSHOT_FLAGS instead of switch/case)
• server.ts imports command sets from commands.ts instead of declaring inline
• SKILL.md and browse/SKILL.md are now generated files (edit the .tmpl instead)

#0.3.2 — 2026-03-13

#Fixed

• Cookie import picker now returns JSON instead of HTML — jsonResponse() referenced url out of scope, crashing every API call
• help command routed correctly (was unreachable due to META_COMMANDS dispatch ordering)
• Stale servers from global install no longer shadow local changes — removed legacy ~/.claude/skills/gstack fallback from resolveServerScript()
• Crash log path references updated from /tmp/ to .gstack/

#Added

• Diff-aware QA mode — /qa on a feature branch auto-analyzes git diff, identifies affected pages/routes, detects the running app on localhost, and tests only what changed. No URL needed.
• Project-local browse state — state file, logs, and all server state now live in .gstack/ inside the project root (detected via git rev-parse --show-toplevel). No more /tmp state files.
• Shared config module (browse/src/config.ts) — centralizes path resolution for CLI and server, eliminates duplicated port/state logic
• Random port selection — server picks a random port 10000-60000 instead of scanning 9400-9409. No more CONDUCTOR_PORT magic offset. No more port collisions across workspaces.
• Binary version tracking — state file includes binaryVersion SHA; CLI auto-restarts the server when the binary is rebuilt
• Legacy /tmp cleanup — CLI scans for and removes old /tmp/browse-server*.json files, verifying PID ownership before sending signals
• Greptile integration — /review and /ship fetch and triage Greptile bot comments; /retro tracks Greptile batting average across weeks
• Local dev mode — bin/dev-setup symlinks skills from the repo for in-place development; bin/dev-teardown restores global install
• help command — agents can self-discover all commands and snapshot flags
• Version-aware find-browse with META signal protocol — detects stale binaries and prompts agents to update
• browse/dist/find-browse compiled binary with git SHA comparison against origin/main (4hr cached)
• .version file written at build time for binary version tracking
• Route-level tests for cookie picker (13 tests) and find-browse version check (10 tests)
• Config resolution tests (14 tests) covering git root detection, BROWSE_STATE_FILE override, ensureStateDir, readVersionHash, resolveServerScript, and version mismatch detection
• Browser interaction guidance in CLAUDE.md — prevents Claude from using mcp__claude-in-chrome__* tools
• CONTRIBUTING.md with quick start, dev mode explanation, and instructions for testing branches in other repos

#Changed

• State file location: .gstack/browse.json (was /tmp/browse-server.json)
• Log files location: .gstack/browse-{console,network,dialog}.log (was /tmp/browse-*.log)
• Atomic state file writes: .json.tmp → rename (prevents partial reads)
• CLI passes BROWSE_STATE_FILE to spawned server (server derives all paths from it)
• SKILL.md setup checks parse META signals and handle META:UPDATE_AVAILABLE
• /qa SKILL.md now describes four modes (diff-aware, full, quick, regression) with diff-aware as the default on feature branches
• jsonResponse/errorResponse use options objects to prevent positional parameter confusion
• Build script compiles both browse and find-browse binaries, cleans up .bun-build temp files
• README updated with Greptile setup instructions, diff-aware QA examples, and revised demo transcript

#Removed

• CONDUCTOR_PORT magic offset (browse_port = CONDUCTOR_PORT - 45600)
• Port scan range 9400-9409
• Legacy fallback to ~/.claude/skills/gstack/browse/src/server.ts
• DEVELOPING_GSTACK.md (renamed to CONTRIBUTING.md)

#0.3.1 — 2026-03-12

#Phase 3.5: Browser cookie import

• cookie-import-browser command — decrypt and import cookies from real Chromium browsers (Comet, Chrome, Arc, Brave, Edge)
• Interactive cookie picker web UI served from the browse server (dark theme, two-panel layout, domain search, import/remove)
• Direct CLI import with --domain flag for non-interactive use
• /setup-browser-cookies skill for Claude Code integration
• macOS Keychain access with async 10s timeout (no event loop blocking)
• Per-browser AES key caching (one Keychain prompt per browser per session)
• DB lock fallback: copies locked cookie DB to /tmp for safe reads
• 18 unit tests with encrypted cookie fixtures

#0.3.0 — 2026-03-12

#Phase 3: /qa skill — systematic QA testing

• New /qa skill with 6-phase workflow (Initialize, Authenticate, Orient, Explore, Document, Wrap up)
• Three modes: full (systematic, 5-10 issues), quick (30-second smoke test), regression (compare against baseline)
• Issue taxonomy: 7 categories, 4 severity levels, per-page exploration checklist
• Structured report template with health score (0-100, weighted across 7 categories)
• Framework detection guidance for Next.js, Rails, WordPress, and SPAs
• browse/bin/find-browse — DRY binary discovery using git rev-parse --show-toplevel

#Phase 2: Enhanced browser

• Dialog handling: auto-accept/dismiss, dialog buffer, prompt text support
• File upload: upload <sel> <file1> [file2...]
• Element state checks: is visible|hidden|enabled|disabled|checked|editable|focused <sel>
• Annotated screenshots with ref labels overlaid (snapshot -a)
• Snapshot diffing against previous snapshot (snapshot -D)
• Cursor-interactive element scan for non-ARIA clickables (snapshot -C)
• wait --networkidle / --load / --domcontentloaded flags
• console --errors filter (error + warning only)
• cookie-import <json-file> with auto-fill domain from page URL
• CircularBuffer O(1) ring buffer for console/network/dialog buffers
• Async buffer flush with Bun.write()
• Health check with page.evaluate + 2s timeout
• Playwright error wrapping — actionable messages for AI agents
• Context recreation preserves cookies/storage/URLs (useragent fix)
• SKILL.md rewritten as QA-oriented playbook with 10 workflow patterns
• 166 integration tests (was ~63)

#0.0.2 — 2026-03-12

• Fix project-local /browse installs — compiled binary now resolves server.ts from its own directory instead of assuming a global install exists
• setup rebuilds stale binaries (not just missing ones) and exits non-zero if the build fails
• Fix chain command swallowing real errors from write commands (e.g. navigation timeout reported as "Unknown meta command")
• Fix unbounded restart loop in CLI when server crashes repeatedly on the same command
• Cap console/network buffers at 50k entries (ring buffer) instead of growing without bound
• Fix disk flush stopping silently after buffer hits the 50k cap
• Fix ln -snf in setup to avoid creating nested symlinks on upgrade
• Use git fetch && git reset --hard instead of git pull for upgrades (handles force-pushes)
• Simplify install: global-first with optional project copy (replaces submodule approach)
• Restructured README: hero, before/after, demo transcript, troubleshooting section
• Six skills (added /retro)

#0.0.1 — 2026-03-11

Initial release.

• Five skills: /plan-ceo-review, /plan-eng-review, /review, /ship, /browse
• Headless browser CLI with 40+ commands, ref-based interaction, persistent Chromium daemon
• One-command install as Claude Code skills (submodule or global clone)
• setup script for binary compilation and skill symlinking
