self-test-skill-invocation

Use a canary test skill to validate framework loading and invocation. The skill emits a unique phrase—CANARY_PHRASE_XYZ123_SKILL_LOADED_AND_INVOKED—to confirm the framework executed it end-to-end without errors or extra output, serving as a health check for your skill infrastructure.

A canary test is a lightweight verification that runs before deploying skills to production. It checks whether the framework can load and invoke skills consistently, catching framework issues early and ensuring skill execution behaves identically in canary and normal modes.

Exact output validation ensures the skill framework processes invocations correctly and returns only the expected result without extraneous content. This guards against silent failures where a skill runs but produces corrupted or partial output, critical for reliable QA and CI workflows.

Yes. Canary skill testing validates framework health and end-to-end invocation flow in QA and CI pipelines. It confirms skills load, execute, and respond consistently, catching framework defects before they reach production skill deployments.

A failed invocation produces missing, corrupted, or extraneous output instead of the exact canary phrase. Canary testing detects this mismatch immediately, signaling that the framework has a loading or execution bug requiring investigation before further skill deployment.
