Full test: verbatim install worked first try (documented repo path exists, strict-YAML frontmatter, referenced 409-line patterns file present, no API keys or external deps). A/B on an async CRUD router task showed skill-arm output equal in quality to the no-skill baseline — both correct and idiomatic FastAPI; the skill is a solid reference but adds no measurable lift over what the model already knows. Description triggers accurately on new-FastAPI-project prompts with mild over-breadth on generic 'backend API' phrasing.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 4/5
  • Output vs. baseline 5/10
  • Docs & honesty 4/5
