QA Commit Skill

Verify that the current commit satisfies its assigned QA Contract criteria (G#N Gherkin scenarios and AC#N acceptance criteria). Returns GREEN (pass) or RED (fail, triggers debug).

When to Use

• After pr-review passes, before git commit
• During Agent Mode commit-level workflow
• Manually with "use qa-commit skill"

Input: Commit Context

Before running, identify:

1. Current commit from Commit Plan
2. Assigned criteria: "Satisfies: G#X, AC#Y, ..."
3. Related files being changed

Phase 1: Load QA Contract

Retrieve the assigned criteria for this commit:

## Commit: [Name]
**Satisfies:** G#1, G#2, AC#1, AC#3

### Criteria to Verify:
- G#1: [Scenario description]
- G#2: [Scenario description]
- AC#1: [Acceptance criteria]
- AC#3: [Acceptance criteria]

Phase 2: Technical Validation

Use Cursor tools for technical checks:

2.1 ReadLints

ReadLints:
  paths: [changed files]

Expect: No errors related to committed functionality

2.2 Type Safety

npm run typecheck

Expect: Exit code 0

2.3 Related Tests (if exist)

npm run test -- --grep "[feature name]"

Expect: All tests pass

Phase 3: Gherkin Verification (Backend - G#N)

For each G#N assigned to this commit:

3.1 Endpoint Existence

Verify the API endpoint exists and is implemented:

SemanticSearch: "Where is [endpoint] implemented?"

3.2 Response Shape

Check response matches expected schema:

Grep: "interface.*Response" in related files

3.3 Error Handling

Verify error cases are handled:

Grep: "throw|catch|error" in handler files

Gherkin Checklist

G#N	Scenario	Status	Notes
G#1	[Name]	PASS/FAIL	[Details]
G#2	[Name]	PASS/FAIL	[Details]

Phase 4: Acceptance Verification (Frontend - AC#N)

For each AC#N assigned to this commit:

4.1 Component Existence

Verify component is implemented:

Glob: **/*[ComponentName]*.tsx

4.2 Storybook Story (if AC involves visual)

Check Storybook story exists:

Glob: **/*[ComponentName]*.stories.tsx

4.3 Browser MCP Verification (if running)

For interactive acceptance criteria:

Browser MCP:
1. browser_navigate to Storybook URL
2. browser_snapshot to check state
3. browser_click/browser_type to test interaction
4. browser_take_screenshot for evidence

AC#N	Criteria	Status	Evidence
AC#1	[Criteria]	PASS/FAIL	[Screenshot/Notes]
AC#3	[Criteria]	PASS/FAIL	[Screenshot/Notes]

Phase 5: Generate Verification Report

## Verification Report

**Commit:** [Name]
**Satisfies:** G#1, G#2, AC#1, AC#3

### Technical Validation

| Check | Status |
|-------|--------|
| ReadLints | PASS/FAIL |
| TypeCheck | PASS/FAIL |
| Tests | PASS/FAIL/SKIP |

### Gherkin Scenarios (Backend)

| ID | Scenario | Status | Notes |
|----|----------|--------|-------|
| G#1 | [Name] | PASS/FAIL | [Details] |
| G#2 | [Name] | PASS/FAIL | [Details] |

### Acceptance Criteria (Frontend)

| ID | Criteria | Status | Evidence |
|----|----------|--------|----------|
| AC#1 | [Criteria] | PASS/FAIL | [Link/Notes] |
| AC#3 | [Criteria] | PASS/FAIL | [Link/Notes] |

### Verdict

**[GREEN / RED]**

[If GREEN: All criteria verified, ready to commit]
[If RED: Failed criteria listed, invoking debug skill]

Phase 6: Handle Verdict

GREEN Verdict

All criteria verified. Proceeding to git commit.

RED Verdict - Auto-Invoke Debug

**Verification failed. Auto-invoking debug skill.**

### Failed Criteria:
- [G#N or AC#N]: [What failed]
- [G#N or AC#N]: [What failed]

### Context for Debug:
- Error messages: [from ReadLints]
- Expected behavior: [from QA Contract]
- Actual behavior: [observed]

Invoking debug skill with context...

After debug fixes, re-run qa-commit to verify.

Integration with Debug

When verdict is RED:

1. Automatically invoke debug skill
2. Pass context:
   • Failed G#N or AC#N
   • Error messages from ReadLints/Shell
   • Browser console/network errors (if applicable)
3. Debug skill fixes issue
4. Re-run qa-commit
5. Repeat until GREEN or user intervention

MCP Tools Used

Tool	Purpose
ReadLints	Get lint/type errors
Shell	Run tests, typecheck
Browser MCP	Storybook verification
SemanticSearch	Find implementations
Grep	Search for patterns

Invocation

Invoked by:

• commit.mdc - After pr-review passes
• agent.mdc - Part of commit-level workflow

Or manually with "use qa-commit skill".
