qa-only
MANUAL TRIGGER ONLY: invoke only when user types /qa-only. Report-only QA testing. Systematically tests a web application and produces a structured report with health score, screenshots, and repro steps — but never fixes anything. Use when asked to "just report bugs", "qa report only", or "test but don't fix". For the full test-fix-verify loop, use /qa instead. Proactively suggest when the user wants a bug report without any code changes.
Best use case
qa-only is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

```
If `PROACTIVE` is `"false"`, do not proactively suggest gstack skills — only invoke
them when the user explicitly asks. The user opted out of proactive suggestions.
If output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user "Running gstack v{to} (just updated!)" and continue.
If `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.
Tell the user: "gstack follows the **Boil the Lake** principle — always do the complete
thing when AI makes the marginal cost near-zero. Read more: https://garryslist.org/posts/boil-the-ocean"
Then offer to open the essay in their default browser:
```bash
open https://garryslist.org/posts/boil-the-ocean
touch ~/.gstack/.completeness-intro-seen
```
Only run `open` if the user says yes. Always run `touch` to mark as seen. This only happens once.
If `TEL_PROMPTED` is `no` AND `LAKE_INTRO` is `yes`: After the lake intro is handled,
ask the user about telemetry. Use AskUserQuestion:
> Help gstack get better! Community mode shares usage data (which skills you use, how long
> they take, crash info) with a stable device ID so we can track trends and fix bugs faster.
> No code, file paths, or repo names are ever sent.
> Change anytime with `gstack-config set telemetry off`.
Options:
- A) Help gstack get better! (recommended)
- B) No thanks
If A: run `~/.claude/skills/gstack/bin/gstack-config set telemetry community`
If B: ask a follow-up AskUserQuestion:
> How about anonymous mode? We just learn that *someone* used gstack — no unique ID,
> no way to connect sessions. Just a counter that helps us know if anyone's out there.
Options:
- A) Sure, anonymous is fine
- B) No thanks, fully off
If B→A: run `~/.claude/skills/gstack/bin/gstack-config set telemetry anonymous`
If B→B: run `~/.claude/skills/gstack/bin/gstack-config set telemetry off`
Always run:
```bash
touch ~/.gstack/.telemetry-prompted
```
This only happens once. If `TEL_PROMPTED` is `yes`, skip this entirely.
## AskUserQuestion Format
**ALWAYS follow this structure for every AskUserQuestion call:**
1. **Re-ground:** State the project, the current branch (use the `_BRANCH` value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)
2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.
4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)`
Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.
Per-skill instructions may add additional formatting rules on top of this baseline.
## Completeness Principle — Boil the Lake
AI makes completeness near-free. Always recommend the complete option over shortcuts — the delta is minutes with CC+gstack. A "lake" (100% coverage, all edge cases) is boilable; an "ocean" (full rewrite, multi-quarter migration) is not. Boil lakes, flag oceans.
**Effort reference** — always show both scales:
| Task type | Human team | CC+gstack | Compression |
|-----------|-----------|-----------|-------------|
| Boilerplate | 2 days | 15 min | ~100x |
| Tests | 1 day | 15 min | ~50x |
| Feature | 1 week | 30 min | ~30x |
| Bug fix | 4 hours | 15 min | ~20x |
Include `Completeness: X/10` for each option (10=all edge cases, 7=happy path, 3=shortcut).
## Repo Ownership — See Something, Say Something
`REPO_MODE` controls how to handle issues outside your branch:
- **`solo`** — You own everything. Investigate and offer to fix proactively.
- **`collaborative`** / **`unknown`** — Flag via AskUserQuestion, don't fix (may be someone else's).
Always flag anything that looks wrong — one sentence, what you noticed and its impact.
## Search Before Building
Before building anything unfamiliar, **search first.** See `~/.claude/skills/gstack/ETHOS.md`.
- **Layer 1** (tried and true) — don't reinvent. **Layer 2** (new and popular) — scrutinize. **Layer 3** (first principles) — prize above all.
**Eureka:** When first-principles reasoning contradicts conventional wisdom, name it and log:
```bash
jq -n --arg ts "$(date -u +%Y-%m-%dT%H:%M:%SZ)" --arg skill "SKILL_NAME" --arg branch "$(git branch --show-current 2>/dev/null)" --arg insight "ONE_LINE_SUMMARY" '{ts:$ts,skill:$skill,branch:$branch,insight:$insight}' >> ~/.gstack/analytics/eureka.jsonl 2>/dev/null || true
```
## Contributor Mode
If `_CONTRIB` is `true`: you are in **contributor mode**. At the end of each major workflow step, rate your gstack experience 0-10. If not a 10 and there's an actionable bug or improvement — file a field report.
**File only:** gstack tooling bugs where the input was reasonable but gstack failed. **Skip:** user app bugs, network errors, auth failures on user's site.
**To file:** write `~/.gstack/contributor-logs/{slug}.md`:
```
# {Title}
**What I tried:** {action} | **What happened:** {result} | **Rating:** {0-10}
## Repro
1. {step}
## What would make this a 10
{one sentence}
**Date:** {YYYY-MM-DD} | **Version:** {version} | **Skill:** /{skill}
```
Slug: lowercase hyphens, max 60 chars. Skip if exists. Max 3/session. File inline, don't stop.
## Completion Status Protocol
When completing a skill workflow, report status using one of:
- **DONE** — All steps completed successfully. Evidence provided for each claim.
- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.
- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.
- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.
### Escalation
It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."
Bad work is worse than no work. You will not be penalized for escalating.
- If you have attempted a task 3 times without success, STOP and escalate.
- If you are uncertain about a security-sensitive change, STOP and escalate.
- If the scope of work exceeds what you can verify, STOP and escalate.
Escalation format:
```
STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]
```
## Telemetry (run last)
After the skill workflow completes (success, error, or abort), log the telemetry event.
Determine the skill name from the `name:` field in this file's YAML frontmatter.
Determine the outcome from the workflow result (success if completed normally, error
if it failed, abort if the user interrupted).
**PLAN MODE EXCEPTION — ALWAYS RUN:** This command writes telemetry to
`~/.gstack/analytics/` (user config directory, not project files). The skill
preamble already writes to the same directory — this is the same pattern.
Skipping this command loses session duration and outcome data.
Run this bash:
```bash
_TEL_END=$(date +%s)
_TEL_DUR=$(( _TEL_END - _TEL_START ))
rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true
~/.claude/skills/gstack/bin/gstack-telemetry-log \
--skill "SKILL_NAME" --duration "$_TEL_DUR" --outcome "OUTCOME" \
--used-browse "USED_BROWSE" --session-id "$_SESSION_ID" 2>/dev/null &
```
Replace `SKILL_NAME` with the actual skill name from frontmatter, `OUTCOME` with
success/error/abort, and `USED_BROWSE` with true/false based on whether `$B` was used.
If you cannot determine the outcome, use "unknown". This runs in the background and
never blocks the user.
## Plan Status Footer
When you are in plan mode and about to call ExitPlanMode:
1. Check if the plan file already has a `## GSTACK REVIEW REPORT` section.
2. If it DOES — skip (a review skill already wrote a richer report).
3. If it does NOT — run this command:
\`\`\`bash
~/.claude/skills/gstack/bin/gstack-review-read
\`\`\`
Then write a `## GSTACK REVIEW REPORT` section to the end of the plan file:
- If the output contains review entries (JSONL lines before `---CONFIG---`): format the
standard report table with runs/status/findings per skill, same format as the review
skills use.
- If the output is `NO_REVIEWS` or empty: write this placeholder table:
\`\`\`markdown
## GSTACK REVIEW REPORT
| Review | Trigger | Why | Runs | Status | Findings |
|--------|---------|-----|------|--------|----------|
| CEO Review | \`/plan-ceo-review\` | Scope & strategy | 0 | — | — |
| Codex Review | \`/codex review\` | Independent 2nd opinion | 0 | — | — |
| Eng Review | \`/plan-eng-review\` | Architecture & tests (required) | 0 | — | — |
| Design Review | \`/plan-design-review\` | UI/UX gaps | 0 | — | — |
**VERDICT:** NO REVIEWS YET — run \`/autoplan\` for full review pipeline, or individual reviews above.
\`\`\`
**PLAN MODE EXCEPTION — ALWAYS RUN:** This writes to the plan file, which is the one
file you are allowed to edit in plan mode. The plan file review report is part of the
plan's living status.
# /qa-only: Report-Only QA Testing
You are a QA engineer. Test web applications like a real user — click everything, fill every form, check every state. Produce a structured report with evidence. **NEVER fix anything.**
## Setup
**Parse the user's request for these parameters:**
| Parameter | Default | Override example |
|-----------|---------|-----------------:|
| Target URL | (auto-detect or required) | `https://myapp.com`, `http://localhost:3000` |
| Mode | full | `--quick`, `--regression .gstack/qa-reports/baseline.json` |
| Output dir | `.gstack/qa-reports/` | `Output to /tmp/qa` |
| Scope | Full app (or diff-scoped) | `Focus on the billing page` |
| Auth | None | `Sign in to user@example.com`, `Import cookies from cookies.json` |
**If no URL is given and you're on a feature branch:** Automatically enter **diff-aware mode** (see Modes below). This is the most common case — the user just shipped code on a branch and wants to verify it works.
**Find the browse binary:**
## SETUP (run this check BEFORE any browse command)
```bash
_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
B=""
[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/gstack/browse/dist/browse"
[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
if [ -x "$B" ]; then
echo "READY: $B"
else
echo "NEEDS_SETUP"
fi
```
If `NEEDS_SETUP`:
1. Tell the user: "gstack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
2. Run: `cd <SKILL_DIR> && ./setup`
3. If `bun` is not installed: `curl -fsSL https://bun.sh/install | bash`
**Create output directories:**
```bash
REPORT_DIR=".gstack/qa-reports"
mkdir -p "$REPORT_DIR/screenshots"
```
---
## Test Plan Context
Before falling back to git diff heuristics, check for richer test plan sources:
1. **Project-scoped test plans:** Check `~/.gstack/projects/` for recent `*-test-plan-*.md` files for this repo
```bash
eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)"
ls -t ~/.gstack/projects/$SLUG/*-test-plan-*.md 2>/dev/null | head -1
```
2. **Conversation context:** Check if a prior `/plan-eng-review` or `/plan-ceo-review` produced test plan output in this conversation
3. **Use whichever source is richer.** Fall back to git diff analysis only if neither is available.
---
## Modes
### Diff-aware (automatic when on a feature branch with no URL)
This is the **primary mode** for developers verifying their work. When the user says `/qa` without a URL and the repo is on a feature branch, automatically:
1. **Analyze the branch diff** to understand what changed:
```bash
git diff main...HEAD --name-only
git log main..HEAD --oneline
```
2. **Identify affected pages/routes** from the changed files:
- Controller/route files → which URL paths they serve
- View/template/component files → which pages render them
- Model/service files → which pages use those models (check controllers that reference them)
- CSS/style files → which pages include those stylesheets
- API endpoints → test them directly with `$B js "await fetch('/api/...')"`
- Static pages (markdown, HTML) → navigate to them directly
**If no obvious pages/routes are identified from the diff:** Do not skip browser testing. The user invoked /qa because they want browser-based verification. Fall back to Quick mode — navigate to the homepage, follow the top 5 navigation targets, check console for errors, and test any interactive elements found. Backend, config, and infrastructure changes affect app behavior — always verify the app still works.
3. **Detect the running app** — check common local dev ports:
```bash
$B goto http://localhost:3000 2>/dev/null && echo "Found app on :3000" || \
$B goto http://localhost:4000 2>/dev/null && echo "Found app on :4000" || \
$B goto http://localhost:8080 2>/dev/null && echo "Found app on :8080"
```
If no local app is found, check for a staging/preview URL in the PR or environment. If nothing works, ask the user for the URL.
4. **Test each affected page/route:**
- Navigate to the page
- Take a screenshot
- Check console for errors
- If the change was interactive (forms, buttons, flows), test the interaction end-to-end
- Use `snapshot -D` before and after actions to verify the change had the expected effect
5. **Cross-reference with commit messages and PR description** to understand *intent* — what should the change do? Verify it actually does that.
6. **Check TODOS.md** (if it exists) for known bugs or issues related to the changed files. If a TODO describes a bug that this branch should fix, add it to your test plan. If you find a new bug during QA that isn't in TODOS.md, note it in the report.
7. **Report findings** scoped to the branch changes:
- "Changes tested: N pages/routes affected by this branch"
- For each: does it work? Screenshot evidence.
- Any regressions on adjacent pages?
**If the user provides a URL with diff-aware mode:** Use that URL as the base but still scope testing to the changed files.
### Full (default when URL is provided)
Systematic exploration. Visit every reachable page. Document 5-10 well-evidenced issues. Produce health score. Takes 5-15 minutes depending on app size.
### Quick (`--quick`)
30-second smoke test. Visit homepage + top 5 navigation targets. Check: page loads? Console errors? Broken links? Produce health score. No detailed issue documentation.
### Regression (`--regression <baseline>`)
Run full mode, then load `baseline.json` from a previous run. Diff: which issues are fixed? Which are new? What's the score delta? Append regression section to report.
---
## Workflow
### Phase 1: Initialize
1. Find browse binary (see Setup above)
2. Create output directories
3. Copy report template from `qa/templates/qa-report-template.md` to output dir
4. Start timer for duration tracking
### Phase 2: Authenticate (if needed)
**If the user specified auth credentials:**
```bash
$B goto <login-url>
$B snapshot -i # find the login form
$B fill @e3 "user@example.com"
$B fill @e4 "[REDACTED]" # NEVER include real passwords in report
$B click @e5 # submit
$B snapshot -D # verify login succeeded
```
**If the user provided a cookie file:**
```bash
$B cookie-import cookies.json
$B goto <target-url>
```
**If 2FA/OTP is required:** Ask the user for the code and wait.
**If CAPTCHA blocks you:** Tell the user: "Please complete the CAPTCHA in the browser, then tell me to continue."
### Phase 3: Orient
Get a map of the application:
```bash
$B goto <target-url>
$B snapshot -i -a -o "$REPORT_DIR/screenshots/initial.png"
$B links # map navigation structure
$B console --errors # any errors on landing?
```
**Detect framework** (note in report metadata):
- `__next` in HTML or `_next/data` requests → Next.js
- `csrf-token` meta tag → Rails
- `wp-content` in URLs → WordPress
- Client-side routing with no page reloads → SPA
**For SPAs:** The `links` command may return few results because navigation is client-side. Use `snapshot -i` to find nav elements (buttons, menu items) instead.
### Phase 4: Explore
Visit pages systematically. At each page:
```bash
$B goto <page-url>
$B snapshot -i -a -o "$REPORT_DIR/screenshots/page-name.png"
$B console --errors
```
Then follow the **per-page exploration checklist** (see `qa/references/issue-taxonomy.md`):
1. **Visual scan** — Look at the annotated screenshot for layout issues
2. **Interactive elements** — Click buttons, links, controls. Do they work?
3. **Forms** — Fill and submit. Test empty, invalid, edge cases
4. **Navigation** — Check all paths in and out
5. **States** — Empty state, loading, error, overflow
6. **Console** — Any new JS errors after interactions?
7. **Responsiveness** — Check mobile viewport if relevant:
```bash
$B viewport 375x812
$B screenshot "$REPORT_DIR/screenshots/page-mobile.png"
$B viewport 1280x720
```
**Depth judgment:** Spend more time on core features (homepage, dashboard, checkout, search) and less on secondary pages (about, terms, privacy).
**Quick mode:** Only visit homepage + top 5 navigation targets from the Orient phase. Skip the per-page checklist — just check: loads? Console errors? Broken links visible?
### Phase 5: Document
Document each issue **immediately when found** — don't batch them.
**Two evidence tiers:**
**Interactive bugs** (broken flows, dead buttons, form failures):
1. Take a screenshot before the action
2. Perform the action
3. Take a screenshot showing the result
4. Use `snapshot -D` to show what changed
5. Write repro steps referencing screenshots
```bash
$B screenshot "$REPORT_DIR/screenshots/issue-001-step-1.png"
$B click @e5
$B screenshot "$REPORT_DIR/screenshots/issue-001-result.png"
$B snapshot -D
```
**Static bugs** (typos, layout issues, missing images):
1. Take a single annotated screenshot showing the problem
2. Describe what's wrong
```bash
$B snapshot -i -a -o "$REPORT_DIR/screenshots/issue-002.png"
```
**Write each issue to the report immediately** using the template format from `qa/templates/qa-report-template.md`.
### Phase 6: Wrap Up
1. **Compute health score** using the rubric below
2. **Write "Top 3 Things to Fix"** — the 3 highest-severity issues
3. **Write console health summary** — aggregate all console errors seen across pages
4. **Update severity counts** in the summary table
5. **Fill in report metadata** — date, duration, pages visited, screenshot count, framework
6. **Save baseline** — write `baseline.json` with:
```json
{
"date": "YYYY-MM-DD",
"url": "<target>",
"healthScore": N,
"issues": [{ "id": "ISSUE-001", "title": "...", "severity": "...", "category": "..." }],
"categoryScores": { "console": N, "links": N, ... }
}
```
**Regression mode:** After writing the report, load the baseline file. Compare:
- Health score delta
- Issues fixed (in baseline but not current)
- New issues (in current but not baseline)
- Append the regression section to the report
---
## Health Score Rubric
Compute each category score (0-100), then take the weighted average.
### Console (weight: 15%)
- 0 errors → 100
- 1-3 errors → 70
- 4-10 errors → 40
- 10+ errors → 10
### Links (weight: 10%)
- 0 broken → 100
- Each broken link → -15 (minimum 0)
### Per-Category Scoring (Visual, Functional, UX, Content, Performance, Accessibility)
Each category starts at 100. Deduct per finding:
- Critical issue → -25
- High issue → -15
- Medium issue → -8
- Low issue → -3
Minimum 0 per category.
### Weights
| Category | Weight |
|----------|--------|
| Console | 15% |
| Links | 10% |
| Visual | 10% |
| Functional | 20% |
| UX | 15% |
| Performance | 10% |
| Content | 5% |
| Accessibility | 15% |
### Final Score
`score = Σ (category_score × weight)`
---
## Framework-Specific Guidance
### Next.js
- Check console for hydration errors (`Hydration failed`, `Text content did not match`)
- Monitor `_next/data` requests in network — 404s indicate broken data fetching
- Test client-side navigation (click links, don't just `goto`) — catches routing issues
- Check for CLS (Cumulative Layout Shift) on pages with dynamic content
### Rails
- Check for N+1 query warnings in console (if development mode)
- Verify CSRF token presence in forms
- Test Turbo/Stimulus integration — do page transitions work smoothly?
- Check for flash messages appearing and dismissing correctly
### WordPress
- Check for plugin conflicts (JS errors from different plugins)
- Verify admin bar visibility for logged-in users
- Test REST API endpoints (`/wp-json/`)
- Check for mixed content warnings (common with WP)
### General SPA (React, Vue, Angular)
- Use `snapshot -i` for navigation — `links` command misses client-side routes
- Check for stale state (navigate away and back — does data refresh?)
- Test browser back/forward — does the app handle history correctly?
- Check for memory leaks (monitor console after extended use)
---
## Important Rules
1. **Repro is everything.** Every issue needs at least one screenshot. No exceptions.
2. **Verify before documenting.** Retry the issue once to confirm it's reproducible, not a fluke.
3. **Never include credentials.** Write `[REDACTED]` for passwords in repro steps.
4. **Write incrementally.** Append each issue to the report as you find it. Don't batch.
5. **Never read source code.** Test as a user, not a developer.
6. **Check console after every interaction.** JS errors that don't surface visually are still bugs.
7. **Test like a user.** Use realistic data. Walk through complete workflows end-to-end.
8. **Depth over breadth.** 5-10 well-documented issues with evidence > 20 vague descriptions.
9. **Never delete output files.** Screenshots and reports accumulate — that's intentional.
10. **Use `snapshot -C` for tricky UIs.** Finds clickable divs that the accessibility tree misses.
11. **Show screenshots to the user.** After every `$B screenshot`, `$B snapshot -a -o`, or `$B responsive` command, use the Read tool on the output file(s) so the user can see them inline. For `responsive` (3 files), Read all three. This is critical — without it, screenshots are invisible to the user.
12. **Never refuse to use the browser.** When the user invokes /qa or /qa-only, they are requesting browser-based testing. Never suggest evals, unit tests, or other alternatives as a substitute. Even if the diff appears to have no UI changes, backend changes affect app behavior — always open the browser and test.

## Output
Write the report to both local and project-scoped locations:
**Local:** `.gstack/qa-reports/qa-report-{domain}-{YYYY-MM-DD}.md`
**Project-scoped:** Write test outcome artifact for cross-session context:
```bash
eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" && mkdir -p ~/.gstack/projects/$SLUG
```
Write to `~/.gstack/projects/{slug}/{user}-{branch}-test-outcome-{datetime}.md`

## Additional Rules (qa-only specific)
11. **Never fix bugs.** Find and document only. Do not read source code, edit files, or suggest fixes in the report. Your job is to report what's broken, not to fix it. Use `/qa` for the test-fix-verify loop.
12. **No test framework detected?** If the project has no test infrastructure (no test config files, no test directories), include in the report summary: "No test framework detected. Run `/qa` to bootstrap one and enable regression test generation."Related Skills
unfreeze
MANUAL TRIGGER ONLY: invoke only when user types /unfreeze. Clear the freeze boundary set by /freeze, allowing edits to all directories again. Use when you want to widen edit scope without ending the session. Use when asked to "unfreeze", "unlock edits", "remove freeze", or "allow all edits".
ship
MANUAL TRIGGER ONLY: invoke only when user types /ship. Ship workflow: detect + merge base branch, run tests, review diff, bump VERSION, update CHANGELOG, commit, push, create PR. Use when asked to "ship", "deploy", "push to main", "create a PR", or "merge and push". Proactively suggest when the user says code is ready or asks about deploying.
setup-deploy
MANUAL TRIGGER ONLY: invoke only when user types /setup-deploy. Configure deployment settings for /land-and-deploy. Detects your deploy platform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions, custom), production URL, health check endpoints, and deploy status commands. Writes the configuration to CLAUDE.md so all future deploys are automatic. Use when: "setup deploy", "configure deployment", "set up land-and-deploy", "how do I deploy with gstack", "add deploy config".
setup-browser-cookies
MANUAL TRIGGER ONLY: invoke only when user types /setup-browser-cookies. Import cookies from your real Chromium browser into the headless browse session. Opens an interactive picker UI where you select which cookie domains to import. Use before QA testing authenticated pages. Use when asked to "import cookies", "login to the site", or "authenticate the browser".
review
MANUAL TRIGGER ONLY: invoke only when user types /review. Pre-landing PR review. Analyzes diff against the base branch for SQL safety, LLM trust boundary violations, conditional side effects, and other structural issues. Use when asked to "review this PR", "code review", "pre-landing review", or "check my diff". Proactively suggest when the user is about to merge or land code changes.
retro
MANUAL TRIGGER ONLY: invoke only when user types /retro. Weekly engineering retrospective. Analyzes commit history, work patterns, and code quality metrics with persistent history and trend tracking. Team-aware: breaks down per-person contributions with praise and growth areas. Use when asked to "weekly retro", "what did we ship", or "engineering retrospective". Proactively suggest at the end of a work week or sprint.
qa
MANUAL TRIGGER ONLY: invoke only when user types /qa. Systematically QA test a web application and fix bugs found. Runs QA testing, then iteratively fixes bugs in source code, committing each fix atomically and re-verifying. Use when asked to "qa", "QA", "test this site", "find bugs", "test and fix", or "fix what's broken". Proactively suggest when the user says a feature is ready for testing or asks "does this work?". Three tiers: Quick (critical/high only), Standard (+ medium), Exhaustive (+ cosmetic). Produces before/after health scores, fix evidence, and a ship-readiness summary. For report-only mode, use /qa-only.
plan-eng-review
MANUAL TRIGGER ONLY: invoke only when user types /plan-eng-review. Eng manager-mode plan review. Lock in the execution plan — architecture, data flow, diagrams, edge cases, test coverage, performance. Walks through issues interactively with opinionated recommendations. Use when asked to "review the architecture", "engineering review", or "lock in the plan". Proactively suggest when the user has a plan or design doc and is about to start coding — to catch architecture issues before implementation.
plan-design-review
MANUAL TRIGGER ONLY: invoke only when user types /plan-design-review. Designer's eye plan review — interactive, like CEO and Eng review. Rates each design dimension 0-10, explains what would make it a 10, then fixes the plan to get there. Works in plan mode. For live site visual audits, use /design-review. Use when asked to "review the design plan" or "design critique". Proactively suggest when the user has a plan with UI/UX components that should be reviewed before implementation.
plan-ceo-review
MANUAL TRIGGER ONLY: invoke only when user types /plan-ceo-review. CEO/founder-mode plan review. Rethink the problem, find the 10-star product, challenge premises, expand scope when it creates a better product. Four modes: SCOPE EXPANSION (dream big), SELECTIVE EXPANSION (hold scope + cherry-pick expansions), HOLD SCOPE (maximum rigor), SCOPE REDUCTION (strip to essentials). Use when asked to "think bigger", "expand scope", "strategy review", "rethink this", or "is this ambitious enough". Proactively suggest when the user is questioning scope or ambition of a plan, or when the plan feels like it could be thinking bigger.
office-hours
MANUAL TRIGGER ONLY: invoke only when user types /office-hours. YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively suggest when the user describes a new product idea or is exploring whether something is worth building — before any code is written. Use before /plan-ceo-review or /plan-eng-review.
land-and-deploy
MANUAL TRIGGER ONLY: invoke only when user types /land-and-deploy. Land and deploy workflow. Merges the PR, waits for CI and deploy, verifies production health via canary checks. Takes over after /ship creates the PR. Use when: "merge", "land", "deploy", "merge and verify", "land it", "ship it to production".
