Test Coverage

Native Subagent Protocol (Codex)

Codex supports native subagents. Delegate with spawn_agent, coordinate with send_input, collect via wait_agent, and clean up with close_agent.

Execution preference:

1. Use native subagents first for independent workstreams (parallel when possible).
2. Merge results in main thread and run final verification.
3. Fallback only when delegation is blocked: use the [ANALYST]/[ARCHITECT]/[EXECUTOR]/[REVIEWER] structure in a single response.

Minimal orchestration pattern:

spawn_agent -> send_input (optional) -> wait_agent -> close_agent

Analyze test coverage and generate missing tests:

1. Run tests with coverage: npm test --coverage or pnpm test --coverage

2. Analyze coverage report (coverage/coverage-summary.json)

3. Identify files below 80% coverage threshold

4. For each under-covered file:

   • Analyze untested code paths
   • Generate unit tests for functions
   • Generate integration tests for APIs
   • Generate E2E tests for critical flows

5. Verify new tests pass

6. Show before/after coverage metrics

7. Ensure project reaches 80%+ overall coverage

Focus on:

• Happy path scenarios
• Error handling
• Edge cases (null, undefined, empty)
• Boundary conditions
