Part 2 of 2 of [[skill-gstack-qa-only]] (qa-only/SKILL.md in garrytan/gstack); the SKILL.md text continues verbatim from the previous part.

## SKILL.md (verbatim, continued)

```bash
console.log("GSTACK_STEP_OK");
'
```

Copy both screenshots out of the printed `ASIDE_DIR` into `$REPORT_DIR/screenshots/` and Read them.

**Static bugs** (typos, layout issues, missing images):
1. Take a single annotated screenshot showing the problem
2. Describe what's wrong

```bash
aside repl '
const pg = await openTab("<page-url>");
const a = await annotatedScreenshot(pg);
await fs.writeFile(path.join(pwd, "issue-002.png"), Buffer.from(a.base64Image, "base64"));
console.log("ASIDE_DIR=" + pwd); await closeTab(pg); console.log("GSTACK_STEP_OK");
'
```

**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.

### Counting
- Deduplicate the same root cause across pages. Use one primary category, first applicable: Links (navigation), Accessibility (access barriers), Functional (behavior), Performance (speed), Visual (layout), Content (copy), UX (friction), Console (remaining errors). No double deductions.
- Exclude **untested** categories; label partial scores **provisional** with coverage. None tested: "not scored". Compare only identical coverage.

### Console (weight: 15%)
Deduplicate reproducible errors/exceptions by message+source across pages. Exclude warnings, info, and defects scored elsewhere.
- 0 errors → 100
- 1-3 errors → 70
- 4-10 errors → 40
- 11+ errors → 10

### Links (weight: 10%)
Count unique broken destinations, including client-side routes: repeatable 4xx/5xx, missing routes/anchors, or timeouts. Exclude expected auth redirects and resource/API requests.
- 0 broken → 100
- Each broken link → -15 (minimum 0)

### Per-Category Scoring (Visual, Functional, UX, Content, Performance, Accessibility)
Start at 100; deduct per finding:
- Critical issue → -25
- High issue → -15
- Medium issue → -8
- Low issue → -3
Floor: 0.

Use the highest applicable severity; record impact/workaround:
- **Critical:** data loss, security/privacy exposure, or core app unusable for all users.
- **High:** core/major task blocked without a workaround.
- **Medium:** task impaired but a workaround exists.
- **Low:** cosmetic/copy/friction issue without lost task completion.
Console/Links use counts instead.

### Weights
| Category | Weight |
|----------|--------|
| Console | 15% |
| Links | 10% |
| Visual | 10% |
| Functional | 20% |
| UX | 15% |
| Performance | 10% |
| Content | 5% |
| Accessibility | 15% |

### Final Score
Use decimal weights (15% = 0.15): `score = Σ (category_score × weight) / Σ tested weights`. Round only the final score to the nearest integer (0.5 rounds up).

## 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(pg, { interactive: true })` for navigation — the links script 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.** You never type them — the user signs in inside Aside. Write `[REDACTED]` if a repro step has to mention one.
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 `annotatedScreenshot(pg)` when the tree misses a clickable element.** Ref labels drawn on the page find clickable divs the accessibility tree skips; then click by ref or CSS selector.
11. **Show screenshots to the user.** After every script that saves a screenshot, `cp` it out of the printed `ASIDE_DIR` into `$REPORT_DIR/screenshots/` and use the Read tool on the copied file so the user can see it inline. 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 in Aside. Never suggest evals, unit tests, curl, or other alternatives as a substitute. Even if the diff appears to have no UI changes, backend changes affect app behavior — always open the app in the browser and test.
13. **Mutating actions on a non-local target need consent.** Submitting, creating, deleting, purchasing, or changing settings on anything that is not LOCAL follows the "Invocation is consent to LOOK, not to ACT" rule in BROWSER SETUP — one AskUserQuestion per run, before the first such action.

## 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`

### Output Structure

```
.gstack/qa-reports/
├── qa-report-{domain}-{YYYY-MM-DD}.md    # Structured report
├── screenshots/

│   ├── issue-001-step-1.jpg               # Per-issue evidence
│   ├── issue-001-result.jpg
│   ├── issue-002.png                      # Annotated screenshot (static bugs)
│   └── ...
└── baseline.json                          # For regression mode
```

Report filenames use the domain and date: `qa-report-myapp-com-2026-03-12.md`

## Capture Learnings

If you discovered a non-obvious pattern, pitfall, or architectural insight during
this session, log it for future sessions:

```bash
~/.claude/skills/gstack/bin/gstack-learnings-log '{"skill":"qa-only","type":"TYPE","key":"SHORT_KEY","insight":"DESCRIPTION","confidence":N,"source":"SOURCE","files":["path/to/relevant/file"]}'
```

**Types:** `pattern` (reusable approach), `pitfall` (what NOT to do), `preference`
(user stated), `architecture` (structural decision), `tool` (library/framework insight),
`operational` (project environment/CLI/workflow knowledge).

**Sources:** `observed` (you found this in the code), `user-stated` (user told you),
`inferred` (AI deduction), `cross-model` (both Claude and Codex agree).

**Confidence:** 1-10. Be honest. An observed pattern you verified in the code is 8-9.
An inference you're not sure about is 4-5. A user preference they explicitly stated is 10.

**files:** Include the specific file paths this learning references. This enables
staleness detection: if those files are later deleted, the learning can be flagged.

**Only log genuine discoveries.** Don't log obvious things. Don't log things the user
already knows. A good test: would this insight save time in a future session? If yes, log it.

## 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."
