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.

* 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.

* 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).

Merge pull request #55 from garrytan/v0.3.6-qa-upgrades
feat: E2E observability + eval infrastructure + all skills templated
fix: auto-clear stale heartbeat when process is dead
Add PID to heartbeat file. eval-watch checks process.kill(pid, 0) and
auto-deletes the heartbeat when the PID is no longer alive — no manual
cleanup needed after crashed/killed E2E runs.

fix: never clean up observability artifacts — partial file persists after finalize
Removing the _partial-e2e.json deletion from finalize(). These are small files
on a local disk and their persistence is the whole point of observability.

fix: detect is_error from claude -p result line (ConnectionRefused was PASS)
claude -p can return subtype="success" with is_error=true when the API is
unreachable. Previously we only checked subtype, so API failures silently
passed. Now check is_error first and report as 'error_api'.

feat: eval-watch dashboard + observability unit tests (15 tests, 11 codepaths)
eval-watch: live terminal dashboard reads heartbeat + partial file every 1s,
shows completed/running tests, stale detection (>10min), --tail flag for
progress.log tail. Pure renderDashboard() function for testability.
observability.test.ts: unit tests for sanitizeTestName, heartbeat schema,
progress.log format, NDJSON file naming, savePartial() with _partial flag,
finalize() cleanup, diagnostic fields, watcher rendering, stale detection,
and non-fatal I/O guarantees.

feat: add E2E observability — heartbeat, progress.log, NDJSON persistence, savePartial()
session-runner: atomic heartbeat file (e2e-live.json), per-run log directory
(~/.gstack-dev/e2e-runs/{runId}/), progress.log + per-test NDJSON persistence,
failure transcripts to persistent run dir instead of tmpdir.
eval-store: 3 new diagnostic fields (exit_reason, timeout_at_turn, last_tool_call),
savePartial() writes _partial-e2e.json after each addTest() for crash resilience,
finalize() cleans up partial file.

fix: remove false-positive Exit code 1 pattern, fix NEEDS_SETUP test, update QA tests
- Remove /Exit code 1/ from BROWSE_ERROR_PATTERNS — too broad, matches any
bash command exit code in the transcript (e.g., git diff, test commands).
Remaining patterns (Unknown command, Unknown snapshot flag, binary not found,
server failed, no such file) are specific to browse errors.
- Fix NEEDS_SETUP E2E test — accepts READY when global binary exists at
~/.claude/skills/gstack/browse/dist/browse (which it does on dev machines).
Test now verifies the setup block handles missing local binary gracefully.
- Update QA skill structure validation tests to match current qa/SKILL.md
template content (phases renamed, modes replaced tiers, output structure).

feat: eval persistence with auto-compare against previous run
EvalCollector accumulates test results during eval runs, writes JSON to
~/.gstack-dev/evals/{version}-{branch}-{tier}-{timestamp}.json, prints
a summary table, and automatically compares against the previous run.
- EvalCollector class with addTest() / finalize() / summary table
- findPreviousRun() prefers same branch, falls back to any branch
- compareEvalResults() matches tests by name, detects improved/regressed
- extractToolSummary() counts tool types from transcript events
- formatComparison() renders delta table with per-test + aggregate diffs
- Wire into skill-e2e.test.ts (recordE2E helper) and skill-llm-eval.test.ts
- 19 unit tests for collector + comparison functions
- schema_version: 1 for forward compatibility

feat: stream-json NDJSON parser for real-time E2E progress
Switch session-runner from buffered `--output-format json` to streaming
`--output-format stream-json --verbose`. Parses NDJSON line-by-line for
real-time tool-by-tool progress on stderr during 3-5 min E2E runs.
- Extract testable `parseNDJSON()` function (pure, no I/O)
- Count turns per assistant event (not per text block)
- Add `transcript: any[]` to SkillTestResult, remove dead `messages` field
- Reconstruct allText from transcript for browse error scanning
- 8 unit tests for parser (malformed lines, empty input, turn counting)

Merge remote-tracking branch 'origin/main' into v0.3.6-qa-upgrades
# Conflicts:
# test/skill-e2e.test.ts
fix: rewrite session-runner to claude -p subprocess, lower flaky baselines
Session runner now spawns `claude -p` as a subprocess instead of using
Agent SDK query(), which fixes E2E tests hanging inside Claude Code.
Also lowers command_reference completeness baseline to 3 (flaky oscillation),
adds test:e2e script, and updates CLAUDE.md.

fix: browse binary discovery broken for agents (v0.3.5) (#44)
* fix: replace find-browse with direct path in SKILL.md setup blocks
Agents were skipping the find-browse binary and guessing bin/browse
(wrong path). Now the setup block explicitly checks browse/dist/browse
with workspace-local priority, global fallback.
Also adds || true to update check to prevent misleading exit code 1.
Adds {{UPDATE_CHECK}} and {{BROWSE_SETUP}} template placeholders to
gen-skill-docs.ts so all skills share a single source of truth.
* refactor: convert qa/ and setup-browser-cookies/ to .tmpl templates
Replaces hardcoded update check and find-browse blocks with
{{UPDATE_CHECK}} and {{BROWSE_SETUP}} placeholders. Both skills
are now generated from templates via gen-skill-docs.
* test: add e2e and LLM eval tests for SKILL.md setup block
- 3 Agent SDK e2e tests: happy path, NEEDS_SETUP, non-git-repo
- LLM eval: setup block clarity + actionability >= 4
- New error pattern: 'no such file or directory.*browse'
These tests catch the exact failure mode where agents can't discover
the browse binary via SKILL.md instructions.
* chore: bump version and changelog (v0.3.5)

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: SKILL.md template system, 3-tier testing, DX tools (v0.3.3) (#41)
* refactor: extract command registry to commands.ts, add SNAPSHOT_FLAGS metadata
- NEW: browse/src/commands.ts — command sets + COMMAND_DESCRIPTIONS + load-time validation (zero side effects)
- server.ts imports from commands.ts instead of declaring sets inline
- snapshot.ts: SNAPSHOT_FLAGS array drives parseSnapshotArgs (metadata-driven, no duplication)
- All 186 existing tests pass
* feat: SKILL.md template system with auto-generated command references
- SKILL.md.tmpl + browse/SKILL.md.tmpl with {{COMMAND_REFERENCE}} and {{SNAPSHOT_FLAGS}} placeholders
- scripts/gen-skill-docs.ts generates SKILL.md from templates (supports --dry-run)
- Build pipeline runs gen:skill-docs before binary compilation
- Generated files have AUTO-GENERATED header, committed to git
* test: Tier 1 static validation — 34 tests for SKILL.md command correctness
- test/helpers/skill-parser.ts: extracts $B commands from code blocks, validates against registry
- test/skill-parser.test.ts: 13 parser/validator unit tests
- test/skill-validation.test.ts: 13 tests validating all SKILL.md files + registry consistency
- test/gen-skill-docs.test.ts: 8 generator tests (categories, sorting, freshness)
* feat: DX tools (skill:check, dev:skill) + Tier 2 E2E test scaffolding
- scripts/skill-check.ts: health summary for all SKILL.md files (commands, templates, freshness)
- scripts/dev-skill.ts: watch mode for template development
- test/helpers/session-runner.ts: Agent SDK wrapper for E2E skill tests
- test/skill-e2e.test.ts: 2 E2E tests + 3 stubs (auto-skip inside Claude Code sessions)
- E2E tests must run from plain terminal: SKILL_E2E=1 bun test test/skill-e2e.test.ts
* ci: SKILL.md freshness check on push/PR + TODO updates
- .github/workflows/skill-docs.yml: fails if generated SKILL.md files are stale
- TODO.md: add E2E cost tracking and model pinning to future ideas
* fix: restore rich descriptions lost in auto-generation
- Snapshot flags: add back value hints (-d <N>, -s <sel>, -o <path>)
- Snapshot flags: restore parenthetical context (@e refs, @c refs, etc.)
- Commands: is → includes valid states enum
- Commands: console → notes --errors filter behavior
- Commands: press → lists common keys (Enter, Tab, Escape)
- Commands: cookie-import-browser → describes picker UI
- Commands: dialog-accept → specifies alert/confirm/prompt
- Tips: restore → arrow (was downgraded to ->)
* test: quality evals for generated SKILL.md descriptions
Catches the exact regressions we shipped and caught in review:
- Snapshot flags must include value hints (-d <N>, -s <sel>, -o <path>)
- is command must list all valid states (visible/hidden/enabled/...)
- press command must list example keys (Enter, Tab, Escape)
- console command must describe --errors behavior
- Snapshot -i must mention @e refs, -C must mention @c refs
- All descriptions must be >= 8 chars (no empty stubs)
- Tips section must use → not ->
* feat: LLM-as-judge evals for SKILL.md documentation quality
4 eval tests using Anthropic API (claude-haiku, ~$0.01-0.03/run):
- Command reference table: clarity/completeness/actionability >= 4/5
- Snapshot flags section: same thresholds
- browse/SKILL.md overall quality
- Regression: generated version must score >= hand-maintained baseline
Requires ANTHROPIC_API_KEY. Auto-skips without it.
Run: bun run test:eval (or ANTHROPIC_API_KEY=sk-... bun test test/skill-llm-eval.test.ts)
* chore: bump version to 0.3.3, update changelog

* feat: conductor.json lifecycle hooks + .env propagation across worktrees
bin/dev-setup now copies .env from main worktree so API keys carry
over to Conductor workspaces automatically. conductor.json wires up
setup and archive hooks.
