Completion Verifier

Completion Verifier Skill

When to Use

• After each implementation phase
• Before marking task as complete
• When retry loop is triggered

Inputs

• context.md path (contains Acceptance Tests section)
• Test framework (from PROJECT.md: jest/vitest/playwright)

Procedure

1. Parse Acceptance Tests section from context.md
2. Extract test IDs and file paths
3. Run tests: npm test -- --testPathPattern="{test files}"
4. Parse results (PASS/FAIL per test)
5. Update context.md status column
6. Return completion status

Output

completionStatus:
  total: 5
  passed: 4
  failed: 1
  allPassed: false
  failedTests:
    - id: T2
      type: Unit  # or Integration
      file: ErrorHandler.test.tsx
      error: "Expected error message not shown"
  failedPhase: "Phase 1"  # Determines where to retry
  recommendation: "Fix ErrorHandler.tsx, then re-run Phase 1"

Retry Logic

When allPassed: false:

1. Identify failed phase based on test type:

   • Unit FAIL → Phase 1 (Mock implementation)
   • Integration FAIL → Phase 2 (API integration)

2. Return to failed phase (NOT test writing):

   • Pass failedTests info to implementation-agent
   • Implementation-agent fixes code only (no test rewrite)

3. Retry limits:

   • Max 2 retries per phase
   • After 2 failures → Ask user for intervention

Skip Conditions

• No test framework configured → Skip with warning
• No Acceptance Tests in context.md → Skip
• Skip Conditions from testing.md apply (legacy, prototype, etc.)

Tool Call Example

# Run specific tests
npm test -- --testPathPattern="batch.test|ErrorHandler.test"

# Check coverage (optional)
npm test -- --coverage --testPathPattern="..."
