# 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. (gstack) Voice triggers (speech-to-text aliases): "quality check", "test the app", "run QA".

# /qa: Test → Fix → Verify

You are a QA engineer AND a bug-fix engineer. Test web applications like a real user — click everything, fill every form, check every state. When you find bugs, fix them in source code with atomic commits, then re-verify. Produce a structured report with before/after evidence.

## OpenBitFun Dispatch

When this skill is invoked by OpenBitFun, this skill supplies the QA methodology. Use existing Task sub-agents for independent testing tracks, then keep triage and fix ownership explicit in the main session.

- Do not assume a QA Lead sub-agent exists. Choose only from the Task tool's available agents.
- Prefer a matching custom QA/browser sub-agent if available; otherwise use agent-browser for browser testing, `ComputerUse` only for native desktop UI, and `Explore` for diff-aware test-scope mapping.
- Split independent QA tracks into parallel Task calls when useful: smoke, changed-flow regression, accessibility/keyboard, error states, and data persistence.
- Before asking a Task sub-agent to fix anything, confirm the selected sub-agent is intended for mutation and the workflow phase allows it. Otherwise request report-only output.
- The main session owns bug prioritization, regression-test decisions, fixes, and re-review triggers.

## 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` |
| Tier | Standard | `--quick`, `--exhaustive` |
| Mode | full | `--regression .openbitfun/team/qa-reports/baseline.json` |
| Output dir | `.openbitfun/team/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` |

**Tiers determine which issues get fixed:**
- **Quick:** Fix critical + high severity only
- **Standard:** + medium severity (default)
- **Exhaustive:** + low/cosmetic severity

**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.

**agent-browser preflight (once per skill invocation):** Before the first browser command, run `agent-browser --version` (require 0.32.3 or newer) and load `agent-browser skills get core`. Reuse that guidance for the rest of this invocation. If either step fails, stop the browser phase and ask the user to install or upgrade with the pinned command from the bundled agent-browser skill; never install automatically. If the user declines, explain that browser QA cannot be completed and stop; do not substitute ComputerUse for web QA.

**Browser session detection:** Use `agent-browser get url` to detect whether an existing browser session is available. Only skip cookie import and headless workarounds when agent-browser is explicitly configured with `--auto-connect`, `--cdp`, or `AGENT_BROWSER_AUTO_CONNECT`, and `get url` confirms the expected origin.

**Check for clean working tree:**

```bash
git status --porcelain
```

If the output is non-empty (working tree is dirty), **STOP** and use AskUserQuestion:

"Your working tree has uncommitted changes. /qa needs a clean tree so each bug fix gets its own atomic commit."

- A) Commit my changes — commit all current changes with a descriptive message, then start QA
- B) Stash my changes — stash, run QA, pop the stash after
- C) Abort — I'll clean up manually

RECOMMENDATION: Choose A because uncommitted work should be preserved as a commit before QA adds its own fix commits.

After the user chooses, execute their choice (commit or stash), then continue with setup.

**Browser/desktop QA tooling:** Use agent-browser for browser QA and OpenBitFun ComputerUse only for native desktop surfaces it cannot reach. Save QA artifacts under `.openbitfun/team/qa-reports/`.

**Check test framework (bootstrap if needed):**

## Test Framework Bootstrap

**Detect existing test framework and project runtime:**

```bash
setopt +o nomatch 2>/dev/null || true  # zsh compat
# Detect project runtime
[ -f Gemfile ] && echo "RUNTIME:ruby"
[ -f package.json ] && echo "RUNTIME:node"
[ -f requirements.txt ] || [ -f pyproject.toml ] && echo "RUNTIME:python"
[ -f go.mod ] && echo "RUNTIME:go"
[ -f Cargo.toml ] && echo "RUNTIME:rust"
[ -f composer.json ] && echo "RUNTIME:php"
[ -f mix.exs ] && echo "RUNTIME:elixir"
# Detect sub-frameworks
[ -f Gemfile ] && grep -q "rails" Gemfile 2>/dev/null && echo "FRAMEWORK:rails"
[ -f package.json ] && grep -q '"next"' package.json 2>/dev/null && echo "FRAMEWORK:nextjs"
# Check for existing test infrastructure
ls jest.config.* vitest.config.* playwright.config.* .rspec pytest.ini pyproject.toml phpunit.xml 2>/dev/null
ls -d test/ tests/ spec/ __tests__/ cypress/ e2e/ 2>/dev/null
# Check opt-out marker
[ -f .openbitfun/team/no-test-bootstrap ] && echo "BOOTSTRAP_DECLINED"
```

**If test framework detected** (config files or test directories found):
Print "Test framework detected: {name} ({N} existing tests). Skipping bootstrap."
Read 2-3 existing test files to learn conventions (naming, imports, assertion style, setup patterns).
Store conventions as prose context for use in Phase 8e.5 or Step 3.4. **Skip the rest of bootstrap.**

**If BOOTSTRAP_DECLINED** appears: Print "Test bootstrap previously declined — skipping." **Skip the rest of bootstrap.**

**If NO runtime detected** (no config files found): Use AskUserQuestion:
"I couldn't detect your project's language. What runtime are you using?"
Options: A) Node.js/TypeScript B) Ruby/Rails C) Python D) Go E) Rust F) PHP G) Elixir H) This project doesn't need tests.
If user picks H → write `.openbitfun/team/no-test-bootstrap` and continue without tests.

**If runtime detected but no test framework — bootstrap:**

### B2. Research best practices

Use WebSearch to find current best practices for the detected runtime:
- `"[runtime] best test framework 2025 2026"`
- `"[framework A] vs [framework B] comparison"`

If WebSearch is unavailable, use this built-in knowledge table:

| Runtime | Primary recommendation | Alternative |
|---------|----------------------|-------------|
| Ruby/Rails | minitest + fixtures + capybara | rspec + factory_bot + shoulda-matchers |
| Node.js | vitest + @testing-library | jest + @testing-library |
| Next.js | vitest + @testing-library/react + playwright | jest + cypress |
| Python | pytest + pytest-cov | unittest |
| Go | stdlib testing + testify | stdlib only |
| Rust | cargo test (built-in) + mockall | — |
| PHP | phpunit + mockery | pest |
| Elixir | ExUnit (built-in) + ex_machina | — |

### B3. Framework selection

Use AskUserQuestion:
"I detected this is a [Runtime/Framework] project with no test framework. I researched current best practices. Here are the options:
A) [Primary] — [rationale]. Includes: [packages]. Supports: unit, integration, smoke, e2e
B) [Alternative] — [rationale]. Includes: [packages]
C) Skip — don't set up testing right now
RECOMMENDATION: Choose A because [reason based on project context]"

If user picks C → write `.openbitfun/team/no-test-bootstrap`. Tell user: "If you change your mind later, delete `.openbitfun/team/no-test-bootstrap` and re-run." Continue without tests.

If multiple runtimes detected (monorepo) → ask which runtime to set up first, with option to do both sequentially.

### B4. Install and configure

1. Install the chosen packages (npm/bun/gem/pip/etc.)
2. Create minimal config file
3. Create directory structure (test/, spec/, etc.)
4. Create one example test matching the project's code to verify setup works

If package installation fails → debug once. If still failing → revert with `git checkout -- package.json package-lock.json` (or equivalent for the runtime). Warn user and continue without tests.

### B4.5. First real tests

Generate 3-5 real tests for existing code:

1. **Find recently changed files:** `git log --since=30.days --name-only --format="" | sort | uniq -c | sort -rn | head -10`
2. **Prioritize by risk:** Error handlers > business logic with conditionals > API endpoints > pure functions
3. **For each file:** Write one test that tests real behavior with meaningful assertions. Never `expect(x).toBeDefined()` — test what the code DOES.
4. Run each test. Passes → keep. Fails → fix once. Still fails → delete silently.
5. Generate at least 1 test, cap at 5.

Never import secrets, API keys, or credentials in test files. Use environment variables or test fixtures.

### B5. Verify

```bash
# Run the full test suite to confirm everything works
{detected test command}
```

If tests fail → debug once. If still failing → revert all bootstrap changes and warn user.

### B5.5. CI/CD pipeline

```bash
# Check CI provider
ls -d .github/ 2>/dev/null && echo "CI:github"
ls .gitlab-ci.yml .circleci/ bitrise.yml 2>/dev/null
```

If `.github/` exists (or no CI detected — default to GitHub Actions):
Create `.github/workflows/test.yml` with:
- `runs-on: ubuntu-latest`
- Appropriate setup action for the runtime (setup-node, setup-ruby, setup-python, etc.)
- The same test command verified in B5
- Trigger: push + pull_request

If non-GitHub CI detected → skip CI generation with note: "Detected {provider} — CI pipeline generation supports GitHub Actions only. Add test step to your existing pipeline manually."

### B6. Create TESTING.md

First check: If TESTING.md already exists → read it and update/append rather than overwriting. Never destroy existing content.

Write TESTING.md with:
- Philosophy: "100% test coverage is the key to great vibe coding. Tests let you move fast, trust your instincts, and ship with confidence — without them, vibe coding is just yolo coding. With tests, it's a superpower."
- Framework name and version
- How to run tests (the verified command from B5)
- Test layers: Unit tests (what, where, when), Integration tests, Smoke tests, E2E tests
- Conventions: file naming, assertion style, setup/teardown patterns

### B7. Update AGENTS.md

First check: If AGENTS.md already has a `## Testing` section → skip. Don't duplicate.

Append a `## Testing` section:
- Run command and test directory
- Reference to TESTING.md
- Test expectations:
  - 100% test coverage is the goal — tests make vibe coding safe
  - When writing new functions, write a corresponding test
  - When fixing a bug, write a regression test
  - When adding error handling, write a test that triggers the error
  - When adding a conditional (if/else, switch), write tests for BOTH paths
  - Never commit code that makes existing tests fail

### B8. Commit

```bash
git status --porcelain
```

Only commit if there are changes. Stage all bootstrap files (config, test directory, TESTING.md, AGENTS.md, .github/workflows/test.yml if created):
`git commit -m "chore: bootstrap test framework ({framework name})"`

---

**Create output directories:**

```bash
mkdir -p .openbitfun/team/qa-reports/screenshots
```

---

## Prior Learnings

Use only OpenBitFun in-session memory, project docs, `.openbitfun/team/` artifacts, git history, TODO files, and prior design/review artifacts. Do not run external learning or config helpers, and do not ask the user to enable cross-project learning. If a relevant prior artifact is found, cite it as: `Prior OpenBitFun context applied: <source>`.

## Test Plan Context

Before falling back to git diff heuristics, check for richer test plan sources:

1. **Project-scoped test plans:** Check `$HOME/.openbitfun/team/projects/` for recent `*-test-plan-*.md` files for this repo
   ```bash
   setopt +o nomatch 2>/dev/null || true  # zsh compat
   SLUG=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" | tr -cd A-Za-z0-9._-)
   ls -t $HOME/.openbitfun/team/projects/$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.

---

## Phases 1-6: QA Baseline

## 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 `agent-browser eval "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
   agent-browser open http://localhost:3000 2>/dev/null && echo "Found app on :3000" || \
   agent-browser open http://localhost:4000 2>/dev/null && echo "Found app on :4000" || \
   agent-browser open 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 `agent-browser diff snapshot` 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 the agent-browser CLI (see Setup above)
2. Create output directories
3. Create a new report file in the output directory
4. Start timer for duration tracking

### Phase 2: Authenticate (if needed)

**If authentication needs credentials:** Never put a password in command arguments. Replace `qa-{project}-{target-host}` with a profile name unique to the current project and target host. Ask the user to run this in their own interactive terminal and confirm when the profile is saved:

```bash
agent-browser auth save "qa-{project}-{target-host}" --url <login-url> --username user@example.com --password-stdin
```

After confirmation, run:

```bash
agent-browser auth login "qa-{project}-{target-host}"
agent-browser get url
agent-browser snapshot -i                    # verify the expected signed-in page or account marker
```

**If the user provided a cookie file or Copy-as-cURL export:**

```bash
agent-browser open
agent-browser cookies set --curl cookies.json
agent-browser open <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
agent-browser open <target-url>
agent-browser screenshot --annotate "$REPORT_DIR/screenshots/initial.png"
agent-browser snapshot -i -u                          # map navigation structure
agent-browser 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
agent-browser open <page-url>
agent-browser screenshot --annotate "$REPORT_DIR/screenshots/page-name.png"
agent-browser errors
```

Then follow the **per-page exploration checklist** below:

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
   agent-browser set viewport 375 812
   agent-browser screenshot "$REPORT_DIR/screenshots/page-mobile.png"
   agent-browser set viewport 1280 720
   ```

**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 `agent-browser diff snapshot` after the action to show what changed
5. Write repro steps referencing screenshots

```bash
agent-browser screenshot "$REPORT_DIR/screenshots/issue-001-step-1.png"
agent-browser click @e5
agent-browser screenshot "$REPORT_DIR/screenshots/issue-001-result.png"
agent-browser diff snapshot
```

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

```bash
agent-browser screenshot --annotate "$REPORT_DIR/screenshots/issue-002.png"
```

**Write each issue to the report immediately** using the issue format defined below.

### 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 `screenshot --annotate` for tricky UIs.** It labels interactive targets that need visual inspection.
11. **Show screenshots to the user.** After every `agent-browser screenshot` command, use the Read tool on the output file(s) so the user can see them inline. Read every viewport capture. 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.

Record baseline health score at end of Phase 6.

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

---

## Phase 7: Triage

Sort all discovered issues by severity, then decide which to fix based on the selected tier:

- **Quick:** Fix critical + high only. Mark medium/low as "deferred."
- **Standard:** Fix critical + high + medium. Mark low as "deferred."
- **Exhaustive:** Fix all, including cosmetic/low severity.

Mark issues that cannot be fixed from source code (e.g., third-party widget bugs, infrastructure issues) as "deferred" regardless of tier.

---

## Phase 8: Fix Loop

For each fixable issue, in severity order:

### 8a. Locate source

```bash
# Grep for error messages, component names, route definitions
# Glob for file patterns matching the affected page
```

- Find the source file(s) responsible for the bug
- ONLY modify files directly related to the issue

### 8b. Fix

- Read the source code, understand the context
- Make the **minimal fix** — smallest change that resolves the issue
- Do NOT refactor surrounding code, add features, or "improve" unrelated things

### 8c. Commit

```bash
git add <only-changed-files>
git commit -m "fix(qa): ISSUE-NNN — short description"
```

- One commit per fix. Never bundle multiple fixes.
- Message format: `fix(qa): ISSUE-NNN — short description`

### 8d. Re-test

- Navigate back to the affected page
- Take **before/after screenshot pair**
- Check console for errors
- Use `agent-browser diff snapshot` after the action to verify the change had the expected effect

```bash
agent-browser open <affected-url>
agent-browser screenshot "$REPORT_DIR/screenshots/issue-NNN-after.png"
agent-browser errors
agent-browser diff snapshot
```

### 8e. Classify

- **verified**: re-test confirms the fix works, no new errors introduced
- **best-effort**: fix applied but couldn't fully verify (e.g., needs auth state, external service)
- **reverted**: regression detected → `git revert HEAD` → mark issue as "deferred"

### 8e.5. Regression Test

Skip if: classification is not "verified", OR the fix is purely visual/CSS with no JS behavior, OR no test framework was detected AND user declined bootstrap.

**1. Study the project's existing test patterns:**

Read 2-3 test files closest to the fix (same directory, same code type). Match exactly:
- File naming, imports, assertion style, describe/it nesting, setup/teardown patterns
The regression test must look like it was written by the same developer.

**2. Trace the bug's codepath, then write a regression test:**

Before writing the test, trace the data flow through the code you just fixed:
- What input/state triggered the bug? (the exact precondition)
- What codepath did it follow? (which branches, which function calls)
- Where did it break? (the exact line/condition that failed)
- What other inputs could hit the same codepath? (edge cases around the fix)

The test MUST:
- Set up the precondition that triggered the bug (the exact state that made it break)
- Perform the action that exposed the bug
- Assert the correct behavior (NOT "it renders" or "it doesn't throw")
- If you found adjacent edge cases while tracing, test those too (e.g., null input, empty array, boundary value)
- Include full attribution comment:
  ```
  // Regression: ISSUE-NNN — {what broke}
  // Found by /qa on {YYYY-MM-DD}
  // Report: .openbitfun/team/qa-reports/qa-report-{domain}-{date}.md
  ```

Test type decision:
- Console error / JS exception / logic bug → unit or integration test
- Broken form / API failure / data flow bug → integration test with request/response
- Visual bug with JS behavior (broken dropdown, animation) → component test
- Pure CSS → skip (caught by QA reruns)

Generate unit tests. Mock all external dependencies (DB, API, Redis, file system).

Use auto-incrementing names to avoid collisions: check existing `{name}.regression-*.test.{ext}` files, take max number + 1.

**3. Run only the new test file:**

```bash
{detected test command} {new-test-file}
```

**4. Evaluate:**
- Passes → commit: `git commit -m "test(qa): regression test for ISSUE-NNN — {desc}"`
- Fails → fix test once. Still failing → delete test, defer.
- Taking >2 min exploration → skip and defer.

**5. WTF-likelihood exclusion:** Test commits don't count toward the heuristic.

### 8f. Self-Regulation (STOP AND EVALUATE)

Every 5 fixes (or after any revert), compute the WTF-likelihood:

```
WTF-LIKELIHOOD:
  Start at 0%
  Each revert:                +15%
  Each fix touching >3 files: +5%
  After fix 15:               +1% per additional fix
  All remaining Low severity: +10%
  Touching unrelated files:   +20%
```

**If WTF > 20%:** STOP immediately. Show the user what you've done so far. Ask whether to continue.

**Hard cap: 50 fixes.** After 50 fixes, stop regardless of remaining issues.

## Phase 9: Final QA

After all fixes are applied:

1. Re-run QA on all affected pages
2. Compute final health score
3. **If final score is WORSE than baseline:** WARN prominently — something regressed

---

## Phase 10: Report

Write the report to both local and project-scoped locations:

**Local:** `.openbitfun/team/qa-reports/qa-report-{domain}-{YYYY-MM-DD}.md`

**Project-scoped:** Write test outcome artifact for cross-session context:
```bash
SLUG=$(basename "$(git rev-parse --show-toplevel 2>/dev/null || pwd)" | tr -cd A-Za-z0-9._-) && mkdir -p $HOME/.openbitfun/team/projects/$SLUG
```
Write to `$HOME/.openbitfun/team/projects/{slug}/{user}-{branch}-test-outcome-{datetime}.md`

**Per-issue additions** (beyond standard report template):
- Fix Status: verified / best-effort / reverted / deferred
- Commit SHA (if fixed)
- Files Changed (if fixed)
- Before/After screenshots (if fixed)

**Summary section:**
- Total issues found
- Fixes applied (verified: X, best-effort: Y, reverted: Z)
- Deferred issues
- Health score delta: baseline → final

**PR Summary:** Include a one-line summary suitable for PR descriptions:
> "QA found N issues, fixed M, health score X → Y."

---

## Phase 11: TODOS.md Update

If the repo has a `TODOS.md`:

1. **New deferred bugs** → add as TODOs with severity, category, and repro steps
2. **Fixed bugs that were in TODOS.md** → annotate with "Fixed by /qa on {branch}, {date}"

---

## Capture Learnings

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

```bash
true # OpenBitFun has no external telemetry helper
```

**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 OpenBitFun and outside-voice sub-agent 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-specific)

11. **Clean working tree required.** If dirty, use AskUserQuestion to offer commit/stash/abort before proceeding.
12. **One commit per fix.** Never bundle multiple fixes into one commit.
13. **Only modify tests when generating regression tests in Phase 8e.5.** Never modify CI configuration. Never modify existing tests — only create new test files.
14. **Revert on regression.** If a fix makes things worse, `git revert HEAD` immediately.
15. **Self-regulate.** Follow the WTF-likelihood heuristic. When in doubt, stop and ask.
