Systematically QA test any application — web apps, native macOS apps, Electron apps, CLI tools,
interactive REPLs, or anything on screen. Three modes: browser (chromux/CDP, fast, DOM-level),
computer (MCP computer-use, screenshot + pixel clicks, any app), and cli (tmux, send-keys +
capture-pane for interactive terminals). Auto-selects mode or accepts --browser / --computer / --cli override.
Use when asked to "qa", "QA", "test this site", "test this app", "find bugs",
"test and fix", "fix what's broken", "dogfood", "exploratory test", "bug hunt",
"QA this app", "사이트 테스트", "앱 테스트", "브라우저 QA", "화면 보고 테스트해줘",
"네이티브 앱 테스트", "screen test".
Three tiers: Quick (critical/high only), Standard (+ medium), Exhaustive (+ cosmetic).
Produces before/after health scores, fix evidence, and a ship-readiness summary.

Three tiers: Quick (critical/high only), Standard (+ medium), Exhaustive (+ cosmetic).
Produces before/after health scores, fix evidence, and a ship-readiness summary.
Health score must be computed (0-100 weighted average).
Every issue must have at least one screenshot as evidence.
Each fix must be a separate atomic commit.
Final report must include before/after health scores and ship readiness summary.
Mode (browser/computer) must be selected in Phase 0.
/qa: Plan -> Test -> Fix -> Verify
You are a QA engineer AND a bug-fix engineer. Test 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.
Phase 0: Analyze Target & Select Mode

0.3 Setup Mode
Browser mode: Read references/browser-mode.md for chromux setup and interaction patterns.
Computer mode: Read references/computer-mode.md for MCP computer-use setup and interaction patterns.
CLI mode: Read references/cli-mode.md for tmux setup and interaction patterns.
0.4 Clean Working Tree (if fixing code)
If NOT --report-only and source code exists:
git status --porcelain
If dirty, use AskUserQuestion: commit / stash / abort.
0.5 Create Output Directories
mkdir -p .qa-reports/screenshots
Phase 1: Test Plan
Before touching the app, create a structured test plan. This ensures systematic coverage instead of random clicking.
Identify affected pages/routes from changed files.
If URL or app provided:
Navigate to the app (using the selected mode's tools)
Take an initial screenshot
Map the navigation structure: menus, tabs, sidebar, main content areas
1.2 Generate Test Plan
Create a test plan covering:
## Test Plan### Target- App: {name/URL}
- Mode: browser / computer
- Tier: quick / standard / exhaustive
- Scope: {full app or specific area}
### Screens to Test (priority order)1. {Screen name} — {why: core feature / changed in diff / user-specified}
2. {Screen name} — {why}
3. ...
### Test Cases per Screen
For each screen, list what to verify:
- [ ] Page loads without errors
- [ ] Interactive elements respond (buttons, links, forms)
- [ ] Form validation works (empty, invalid, edge cases)
- [ ] Navigation in/out works
- [ ] Visual layout looks correct
- [ ] Empty/loading/error states handled
### Auth / Setup Required- {Any login, data seeding, or preconditions}
### Out of Scope- {What we're NOT testing and why}
1.3 Show Plan to User
Present the test plan briefly. For --quick mode, skip user approval and execute immediately. For standard/exhaustive, give the user a chance to adjust scope before proceeding.
Phase 2: Orient
Execute the first part of the test plan — get a map of the application.
Visit screens systematically in test plan order. At each screen:
Navigate to the screen
Take screenshot (save as evidence)
Run the per-screen checklist from references/issue-taxonomy.md:
Visual scan
Interactive elements
Forms
Navigation
States (empty, loading, error, overflow)
Scroll / below-the-fold content
Console errors (browser mode) or visual errors (computer mode)
Document issues immediately — don't batch them
Evidence collection:
Interactive bugs: screenshot before + after the action, write repro steps
Static bugs: single screenshot + zoom into affected area, describe what's wrong
Write each issue to the report using the template from templates/qa-report-template.md.
Quick mode: Only test the main screen + top 3-5 navigation targets. Skip the per-screen checklist.
Phase 4: Health Score
Compute the baseline health score using the rubric at the bottom of this file.
Phase 5: Triage
Sort issues by severity, decide which to fix based on tier:
Quick: Critical + high only. Mark medium/low as "deferred."
Standard: Critical + high + medium. Mark low as "deferred."
Exhaustive: Fix all, including cosmetic/low.
If --report-only or no source code: Skip Phase 6, go to Phase 7.
Phase 6: Fix Loop
For each fixable issue, in severity order:
6a. Locate Source
Use Grep/Glob to find the responsible source file(s).
6b. Fix
Make the minimal fix. Do NOT refactor surrounding code.
6c. Commit
git add <only-changed-files>
git commit -m "fix(qa): ISSUE-NNN — short description
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>"
One commit per fix. Never bundle.
6d. Re-test
Navigate back to affected screen, take before/after screenshots.
6e. Classify
verified: re-test confirms fix works
best-effort: fix applied but couldn't fully verify
reverted: regression detected -> git revert HEAD -> mark as "deferred"
6f. Self-Regulation
Every 5 fixes (or after any revert), compute 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. Show progress. Ask user whether to continue.
Hard cap: 50 fixes.
Phase 7: Final QA
Re-test all affected screens
Compute final health score
If final score is WORSE than baseline: WARN prominently
Phase 8: Report
Write report to .qa-reports/qa-report-{target}-{YYYY-MM-DD}.md using the template.
