Runtime Verifier

Use when a code change must be verified by actually running the app, endpoint, or CLI flow instead of relying only on unit tests.

Use this skill to verify that a change behaves correctly in a running system.

Workflow

1. Translate the request into a concrete verification plan.
2. Start the needed app, server, or CLI environment.
3. Execute the runtime checks exactly as planned.
4. Report pass/fail per step with evidence.
5. Clean up any processes or sessions you started.

Guardrails

• Do not confuse unit test coverage with runtime verification.
• Prefer observable outcomes over vague confidence statements.
• Update the verifier instructions if the environment changed and the failure is instruction drift, not product breakage.

Example Requests

• Actually run the app and prove this change works.
• Verify this endpoint or CLI flow in a live environment.

Inputs

• Verification target
• Expected runtime behavior
• Environment startup instructions

Outputs

• Verification plan
• Pass/fail evidence
• Cleanup summary

Success Criteria

• The behavior was exercised in a live runtime.
• Evidence is explicit.
• Started processes were cleaned up.

Non-Goals

• Stopping at unit tests only
• Vague confidence statements with no evidence
