The instructions your model reads when the skill loads.
Search available built-in, user, repository, plugin, and user-provided skill sources before recommending a new skill.
Translate the request into a small set of capability, tool, artifact, and trigger terms. Search skill names and descriptions first; inspect full instructions only for plausible candidates.
Use the host environment's supported skill catalog or filesystem locations. For current Codex projects, repository skills are typically discovered under .agents/skills/; user-level and plugin locations depend on the installed environment and should be verified before changing them.

If no strong match exists, explain the gap and outline the smallest new skill needed. Do not install, copy, or modify skills unless the user asks.
