# TODOS

## Browse

### Bundle server.ts into compiled binary

**What:** Eliminate `resolveServerScript()` fallback chain entirely — bundle server.ts into the compiled browse binary.

**Why:** The current fallback chain (check adjacent to cli.ts, check global install) is fragile and caused bugs in v0.3.2. A single compiled binary is simpler and more reliable.

**Context:** Bun's `--compile` flag can bundle multiple entry points. The server is currently resolved at runtime via file path lookup. Bundling it removes the resolution step entirely.

**Effort:** M
**Priority:** P2
**Depends on:** None

### Sessions (isolated browser instances)

**What:** Isolated browser instances with separate cookies/storage/history, addressable by name.

**Why:** Enables parallel testing of different user roles, A/B test verification, and clean auth state management.

**Context:** Requires Playwright browser context isolation. Each session gets its own context with independent cookies/localStorage. Prerequisite for video recording (clean context lifecycle) and auth vault.

**Effort:** L
**Priority:** P3

### Video recording

**What:** Record browser interactions as video (start/stop controls).

**Why:** Video evidence in QA reports and PR bodies. Currently deferred because `recreateContext()` destroys page state.

**Context:** Needs sessions for clean context lifecycle. Playwright supports video recording per context. Also needs WebM → GIF conversion for PR embedding.

**Effort:** M
**Priority:** P3
**Depends on:** Sessions

### v20 encryption format support

**What:** AES-256-GCM support for future Chromium cookie DB versions (currently v10).

**Why:** Future Chromium versions may change encryption format. Proactive support prevents breakage.

**Effort:** S
**Priority:** P3

### State persistence

**What:** Save/load cookies + localStorage to JSON files for reproducible test sessions.

**Why:** Enables "resume where I left off" for QA sessions and repeatable auth states.

**Effort:** M
**Priority:** P3
**Depends on:** Sessions

### Auth vault

**What:** Encrypted credential storage, referenced by name. LLM never sees passwords.

**Why:** Security — currently auth credentials flow through the LLM context. Vault keeps secrets out of the AI's view.

**Effort:** L
**Priority:** P3
**Depends on:** Sessions, state persistence

### Iframe support

**What:** `frame <sel>` and `frame main` commands for cross-frame interaction.

**Why:** Many web apps use iframes (embeds, payment forms, ads). Currently invisible to browse.

**Effort:** M
**Priority:** P4

### Semantic locators

**What:** `find role/label/text/placeholder/testid` with attached actions.

**Why:** More resilient element selection than CSS selectors or ref numbers.

**Effort:** M
**Priority:** P4

### Device emulation presets

**What:** `set device "iPhone 16 Pro"` for mobile/tablet testing.

**Why:** Responsive layout testing without manual viewport resizing.

**Effort:** S
**Priority:** P4

### Network mocking/routing

**What:** Intercept, block, and mock network requests.

**Why:** Test error states, loading states, and offline behavior.

**Effort:** M
**Priority:** P4

### Download handling

**What:** Click-to-download with path control.

**Why:** Test file download flows end-to-end.

**Effort:** S
**Priority:** P4

### Content safety

**What:** `--max-output` truncation, `--allowed-domains` filtering.

**Why:** Prevent context window overflow and restrict navigation to safe domains.

**Effort:** S
**Priority:** P4

### Streaming (WebSocket live preview)

**What:** WebSocket-based live preview for pair browsing sessions.

**Why:** Enables real-time collaboration — human watches AI browse.

**Effort:** L
**Priority:** P4

### CDP mode

**What:** Connect to already-running Chrome/Electron apps via Chrome DevTools Protocol.

**Why:** Test production apps, Electron apps, and existing browser sessions without launching new instances.

**Effort:** M
**Priority:** P4

### Linux/Windows cookie decryption

**What:** GNOME Keyring / kwallet / DPAPI support for non-macOS cookie import.

**Why:** Cross-platform cookie import. Currently macOS-only (Keychain).

**Effort:** L
**Priority:** P4

## Ship

### Ship log — persistent record of /ship runs

**What:** Append structured JSON entry to `.gstack/ship-log.json` at end of every /ship run (version, date, branch, PR URL, review findings, Greptile stats, todos completed, test results).

**Why:** /retro has no structured data about shipping velocity. Ship log enables: PRs-per-week trending, review finding rates, Greptile signal over time, test suite growth.

**Context:** /retro already reads greptile-history.md — same pattern. Eval persistence (eval-store.ts) shows the JSON append pattern exists in the codebase. ~15 lines in ship template.

**Effort:** S
**Priority:** P2
**Depends on:** None

### Post-deploy verification (ship + browse)

**What:** After push, browse staging/preview URL, screenshot key pages, check console for JS errors, compare staging vs prod via snapshot diff. Include verification screenshots in PR body. STOP if critical errors found.

**Why:** Catch deployment-time regressions (JS errors, broken layouts) before merge.

**Context:** Requires S3 upload infrastructure for PR screenshots. Pairs with visual PR annotations.

**Effort:** L
**Priority:** P2
**Depends on:** /setup-gstack-upload, visual PR annotations

### Visual verification with screenshots in PR body

**What:** /ship Step 7.5: screenshot key pages after push, embed in PR body.

**Why:** Visual evidence in PRs. Reviewers see what changed without deploying locally.

**Context:** Part of Phase 3.6. Needs S3 upload for image hosting.

**Effort:** M
**Priority:** P2
**Depends on:** /setup-gstack-upload

## Review

### Inline PR annotations

**What:** /ship and /review post inline review comments at specific file:line locations using `gh api` to create pull request review comments.

**Why:** Line-level annotations are more actionable than top-level comments. The PR thread becomes a line-by-line conversation between Greptile, Claude, and human reviewers.

**Context:** GitHub supports inline review comments via `gh api repos/$REPO/pulls/$PR/reviews`. Pairs naturally with Phase 3.6 visual annotations.

**Effort:** S
**Priority:** P2
**Depends on:** None

### Greptile training feedback export

**What:** Aggregate greptile-history.md into machine-readable JSON summary of false positive patterns, exportable to the Greptile team for model improvement.

**Why:** Closes the feedback loop — Greptile can use FP data to stop making the same mistakes on your codebase.

**Context:** Was a P3 Future Idea. Upgraded to P2 now that greptile-history.md data infrastructure exists. The signal data is already being collected; this just makes it exportable. ~40 lines.

**Effort:** S
**Priority:** P2
**Depends on:** Enough FP data accumulated (10+ entries)

### Visual review with annotated screenshots

**What:** /review Step 4.5: browse PR's preview deploy, annotated screenshots of changed pages, compare against production, check responsive layouts, verify accessibility tree.

**Why:** Visual diff catches layout regressions that code review misses.

**Context:** Part of Phase 3.6. Needs S3 upload for image hosting.

**Effort:** M
**Priority:** P2
**Depends on:** /setup-gstack-upload

## QA

### QA trend tracking

**What:** Compare baseline.json over time, detect regressions across QA runs.

**Why:** Spot quality trends — is the app getting better or worse?

**Context:** QA already writes structured reports. This adds cross-run comparison.

**Effort:** S
**Priority:** P2

### CI/CD QA integration

**What:** `/qa` as GitHub Action step, fail PR if health score drops.

**Why:** Automated quality gate in CI. Catch regressions before merge.

**Effort:** M
**Priority:** P2

### Smart default QA tier

**What:** After a few runs, check index.md for user's usual tier pick, skip the AskUserQuestion.

**Why:** Reduces friction for repeat users.

**Effort:** S
**Priority:** P2

### Accessibility audit mode

**What:** `--a11y` flag for focused accessibility testing.

**Why:** Dedicated accessibility testing beyond the general QA checklist.

**Effort:** S
**Priority:** P3

### CI/CD generation for non-GitHub providers

**What:** Extend CI/CD bootstrap to generate GitLab CI (`.gitlab-ci.yml`), CircleCI (`.circleci/config.yml`), and Bitrise pipelines.

**Why:** Not all projects use GitHub Actions. Universal CI/CD bootstrap would make test bootstrap work for everyone.

**Context:** v1 ships with GitHub Actions only. Detection logic already checks for `.gitlab-ci.yml`, `.circleci/`, `bitrise.yml` and skips with an informational note. Each provider needs ~20 lines of template text in `generateTestBootstrap()`.

**Effort:** M
**Priority:** P3
**Depends on:** Test bootstrap (shipped)

### Auto-upgrade weak tests (★) to strong tests (★★★)

**What:** When Step 3.4 coverage audit identifies existing ★-rated tests (smoke/trivial assertions), generate improved versions testing edge cases and error paths.

**Why:** Many codebases have tests that technically exist but don't catch real bugs — `expect(component).toBeDefined()` isn't testing behavior. Upgrading these closes the gap between "has tests" and "has good tests."

**Context:** Requires the quality scoring rubric from the test coverage audit. Modifying existing test files is riskier than creating new ones — needs careful diffing to ensure the upgraded test still passes. Consider creating a companion test file rather than modifying the original.

**Effort:** M
**Priority:** P3
**Depends on:** Test quality scoring (shipped)

## Retro

### Deployment health tracking (retro + browse)

**What:** Screenshot production state, check perf metrics (page load times), count console errors across key pages, track trends over retro window.

**Why:** Retro should include production health alongside code metrics.

**Context:** Requires browse integration. Screenshots + metrics fed into retro output.

**Effort:** L
**Priority:** P3
**Depends on:** Browse sessions

## Infrastructure

### /setup-gstack-upload skill (S3 bucket)

**What:** Configure S3 bucket for image hosting. One-time setup for visual PR annotations.

**Why:** Prerequisite for visual PR annotations in /ship and /review.

**Effort:** M
**Priority:** P2

### gstack-upload helper

**What:** `browse/bin/gstack-upload` — upload file to S3, return public URL.

**Why:** Shared utility for all skills that need to embed images in PRs.

**Effort:** S
**Priority:** P2
**Depends on:** /setup-gstack-upload

### WebM to GIF conversion

**What:** ffmpeg-based WebM → GIF conversion for video evidence in PRs.

**Why:** GitHub PR bodies render GIFs but not WebM. Needed for video recording evidence.

**Effort:** S
**Priority:** P3
**Depends on:** Video recording

### Deploy-verify skill

**What:** Lightweight post-deploy smoke test: hit key URLs, verify 200s, screenshot critical pages, console error check, compare against baseline snapshots. Pass/fail with evidence.

**Why:** Fast post-deploy confidence check, separate from full QA.

**Effort:** M
**Priority:** P2

### GitHub Actions eval upload

**What:** Run eval suite in CI, upload result JSON as artifact, post summary comment on PR.

**Why:** CI integration catches quality regressions before merge and provides persistent eval records per PR.

**Context:** Requires `ANTHROPIC_API_KEY` in CI secrets. Cost is ~$4/run. Eval persistence system (v0.3.6) writes JSON to `~/.gstack-dev/evals/` — CI would upload as GitHub Actions artifacts and use `eval:compare` to post delta comment.

**Effort:** M
**Priority:** P2
**Depends on:** Eval persistence (shipped in v0.3.6)

### E2E model pinning

**What:** Pin E2E tests to claude-sonnet-4-6 for cost efficiency, add retry:2 for flaky LLM responses.

**Why:** Reduce E2E test cost and flakiness.

**Effort:** XS
**Priority:** P2

### Eval web dashboard

**What:** `bun run eval:dashboard` serves local HTML with charts: cost trending, detection rate, pass/fail history.

**Why:** Visual charts better for spotting trends than CLI tools.

**Context:** Reads `~/.gstack-dev/evals/*.json`. ~200 lines HTML + chart.js via Bun HTTP server.

**Effort:** M
**Priority:** P3
**Depends on:** Eval persistence (shipped in v0.3.6)

### CI/CD QA quality gate

**What:** Run `/qa` as a GitHub Action step, fail PR if health score drops below threshold.

**Why:** Automated quality gate catches regressions before merge. Currently QA is manual — CI integration makes it part of the standard workflow.

**Context:** Requires headless browse binary available in CI. The `/qa` skill already produces `baseline.json` with health scores — CI step would compare against the main branch baseline and fail if score drops. Would need `ANTHROPIC_API_KEY` in CI secrets since `/qa` uses Claude.

**Effort:** M
**Priority:** P2
**Depends on:** None

### Cross-platform URL open helper

**What:** `gstack-open-url` helper script — detect platform, use `open` (macOS) or `xdg-open` (Linux).

**Why:** The first-time Completeness Principle intro uses macOS `open` to launch the essay. If gstack ever supports Linux, this silently fails.

**Effort:** S (human: ~30 min / CC: ~2 min)
**Priority:** P4
**Depends on:** Nothing

### CDP-based DOM mutation detection for ref staleness

**What:** Use Chrome DevTools Protocol `DOM.documentUpdated` / MutationObserver events to proactively invalidate stale refs when the DOM changes, without requiring an explicit `snapshot` call.

**Why:** Current ref staleness detection (async count() check) only catches stale refs at action time. CDP mutation detection would proactively warn when refs become stale, preventing the 5-second timeout entirely for SPA re-renders.

**Context:** Parts 1+2 of ref staleness fix (RefEntry metadata + eager validation via count()) are shipped. This is Part 3 — the most ambitious piece. Requires CDP session alongside Playwright, MutationObserver bridge, and careful performance tuning to avoid overhead on every DOM change.

**Effort:** L
**Priority:** P3
**Depends on:** Ref staleness Parts 1+2 (shipped)

## Office Hours / Design

### Design docs → Supabase team store sync

**What:** Add design docs (`*-design-*.md`) to the Supabase sync pipeline alongside test plans, retro snapshots, and QA reports.

**Why:** Cross-team design discovery at scale. Local `~/.gstack/projects/$SLUG/` keyword-grep discovery works for same-machine users now, but Supabase sync makes it work across the whole team. Duplicate ideas surface, everyone sees what's been explored.

**Context:** /office-hours writes design docs to `~/.gstack/projects/$SLUG/`. The team store already syncs test plans, retro snapshots, QA reports. Design docs follow the same pattern — just add a sync adapter.

**Effort:** S
**Priority:** P2
**Depends on:** `garrytan/team-supabase-store` branch landing on main

## Debug

### Worktree-based parallel debug sub-agents

**What:** When /qa hits multiple stubborn bugs, spawn parallel debug agents each in their own git worktree (`isolation: "worktree"` on the Agent call). They investigate simultaneously while /qa continues other work. Results cherry-picked back.

**Why:** Sequential debug investigations add ~2-5 min per bug. With 3-4 hard bugs, that's 10-20 min of sequential waiting. Parallel worktree agents could investigate all simultaneously, with zero working-tree conflicts.

**Context:** v1 ships sequential (debug-subagent-escalation PR). The Agent tool supports `isolation: "worktree"` which creates a temporary git worktree — each agent gets its own copy of the repo. Especially powerful in plan mode where /qa might find multiple hard bugs across different subsystems.

**Effort:** M (human: ~1 week / CC: ~30min)
**Priority:** P2
**Depends on:** Sequential debug escalation (debug-subagent-escalation PR)

## Design Review

### /plan-design-review + /qa-design-review + /design-consultation — SHIPPED

Shipped as v0.5.0 on main. Includes `/plan-design-review` (report-only design audit), `/qa-design-review` (audit + fix loop), and `/design-consultation` (interactive DESIGN.md creation). `{{DESIGN_METHODOLOGY}}` resolver provides shared 80-item design audit checklist.

## Document-Release

### Auto-invoke /document-release from /ship

**What:** Add Step 8.5 to /ship that reads document-release/SKILL.md and executes the doc update workflow after creating the PR.

**Why:** Zero-friction doc updates — user runs /ship and docs are automatically current. No extra command to remember.

**Context:** /ship currently ends at Step 8 (PR URL output). Step 8.5 would continue into the document-release workflow. Same pattern as /ship calling /review's checklist in Step 3.5.

**Effort:** S
**Priority:** P1
**Depends on:** /document-release shipped

### `{{DOC_VOICE}}` shared resolver

**What:** Create a placeholder resolver in gen-skill-docs.ts encoding the gstack voice guide (friendly, user-forward, lead with benefits). Inject into /ship Step 5, /document-release Step 5, and reference from CLAUDE.md.

**Why:** DRY — voice rules currently live inline in 3 places (CLAUDE.md CHANGELOG style section, /ship Step 5, /document-release Step 5). When the voice evolves, all three drift.

**Context:** Same pattern as `{{QA_METHODOLOGY}}` — shared block injected into multiple templates to prevent drift. ~20 lines in gen-skill-docs.ts.

**Effort:** S
**Priority:** P2
**Depends on:** None

## Ship Confidence Dashboard

### Smart review relevance detection — PARTIALLY SHIPPED

~~**What:** Auto-detect which of the 4 reviews are relevant based on branch changes (skip Design Review if no CSS/view changes, skip Code Review if plan-only).~~

`bin/gstack-diff-scope` shipped — categorizes diff into SCOPE_FRONTEND, SCOPE_BACKEND, SCOPE_PROMPTS, SCOPE_TESTS, SCOPE_DOCS, SCOPE_CONFIG. Used by design-review-lite to skip when no frontend files changed. Dashboard integration for conditional row display is a follow-up.

**Remaining:** Dashboard conditional row display (hide "Design Review: NOT YET RUN" when SCOPE_FRONTEND=false). Extend to Eng Review (skip for docs-only) and CEO Review (skip for config-only).

**Effort:** S
**Priority:** P3
**Depends on:** gstack-diff-scope (shipped)

### /merge skill — review-gated PR merge

**What:** Create a `/merge` skill that merges an approved PR, but first checks the Review Readiness Dashboard and runs `/review` (Fix-First) if code review hasn't been done. Separates "ship" (create PR) from "merge" (land it).

**Why:** Currently `/review` runs inside `/ship` Step 3.5 but isn't tracked as a gate. A `/merge` skill ensures code review always happens before landing, and enables workflows where someone else reviews the PR first.

**Context:** `/ship` creates the PR. `/merge` would: check dashboard → run `/review` if needed → `gh pr merge`. This is where code review tracking belongs — at merge time, not at plan time.

**Effort:** M
**Priority:** P2
**Depends on:** Ship Confidence Dashboard (shipped)

## Completeness

### Completeness metrics dashboard

**What:** Track how often Claude chooses the complete option vs shortcut across gstack sessions. Aggregate into a dashboard showing completeness trend over time.

**Why:** Without measurement, we can't know if the Completeness Principle is working. Could surface patterns (e.g., certain skills still bias toward shortcuts).

**Context:** Would require logging choices (e.g., append to a JSONL file when AskUserQuestion resolves), parsing them, and displaying trends. Similar pattern to eval persistence.

**Effort:** M (human) / S (CC)
**Priority:** P3
**Depends on:** Boil the Lake shipped (v0.6.1)

## Safety & Observability

### On-demand hook skills (/careful, /freeze, /guard)

**What:** Three new skills that use Claude Code's session-scoped PreToolUse hooks to add safety guardrails on demand.

**Why:** Anthropic's internal skill best practices recommend on-demand hooks for safety. Claude Code already handles destructive command permissions, but these add an explicit opt-in layer for high-risk sessions (touching prod, debugging live systems).

**Skills:**
- `/careful` — PreToolUse hook on Bash tool. Warns (not blocks) before destructive commands: `rm -rf`, `DROP TABLE`, `git push --force`, `git reset --hard`, `kubectl delete`, `docker system prune`. Uses `permissionDecision: "ask"` so user can override.
- `/freeze` — PreToolUse hook on Edit/Write tools. Restricts file edits to a user-specified directory. Great for debugging without accidentally "fixing" unrelated code.
- `/guard` — meta-skill composing `/careful` + `/freeze` into one command.

**Implementation notes:** Use `${CLAUDE_SKILL_DIR}` (not `${SKILL_DIR}`) for script paths in hook commands. Pure bash JSON parsing (no jq dependency). Freeze dir storage: `${CLAUDE_PLUGIN_DATA}/freeze-dir.txt` with `~/.gstack/freeze-dir.txt` fallback. Ensure trailing `/` on freeze dir paths to prevent `/src` matching `/src-old`.

**Effort:** M (human) / S (CC)
**Priority:** P3
**Depends on:** None

### Skill usage telemetry

**What:** Track which skills get invoked, how often, from which repo.

**Why:** Enables finding undertriggering skills and measuring adoption. Anthropic uses a PreToolUse hook for this; simpler approach is appending JSONL from the preamble.

**Context:** Add to `generatePreamble()` in `scripts/gen-skill-docs.ts`. Append to `~/.gstack/analytics/skill-usage.jsonl` with skill name, timestamp, and repo name. `mkdir -p` ensures the directory exists.

**Effort:** S (human) / S (CC)
**Priority:** P3
**Depends on:** None
