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="..."

Self-Audit Pattern

After implementation, compare results against context.md requirements to verify fulfillment.

Purpose

According to the "How to write a good spec for AI agents" guide, having AI verify its own work against the spec is a powerful pattern. This helps catch missing items before running tests.

Trigger

• After each implementation phase
• Before test execution

Prompt Example

At completion, verify the following:

"After implementation, compare your results against the requirements in context.md and verify each item is fulfilled. If any requirements are not met, list them."

Self-Audit Output Format

selfAuditResult:
  # Requirements fulfillment
  requirementsMet:
    - "[REQ-1] User query API ✅"
    - "[REQ-2] Error handling ✅"
  requirementsNotMet:
    - "[REQ-3] Pagination ❌ (not implemented)"
  
  # 3-tier boundary check
  boundaryCheck:
    neverDoViolations: []          # Critical violations (halt if any)
    askFirstItems: []              # Items needing approval
    alwaysDoCompleted:             # Required actions
      - "lint executed"
      - "tests passed"
  
  # Overall judgment
  readyForTest: true | false
  blockers:                        # Blocking reasons if false
    - "REQ-3 not implemented"

Workflow Integration

Implementation Phase Complete
        ↓
[Self-Audit] Compare against context.md requirements
        ↓
    readyForTest?
     ↓         ↓
   true      false
     ↓         ↓
Run tests   Fix implementation and retry

Notes

• Self-Audit is a supplementary check, not a replacement for actual tests
• Requirement fulfillment involves subjective judgment; tests provide final verification
• If

  neverDoViolations

  exist, halt immediately and report to user
