	Description		Read-only	Idempotent	Open world
`check_skill_repo`Static check of every SKILL.md (Claude Code / Codex agent skills) in a public GitHub repo: frontmatter and YAML errors, name/folder mismatch, missing or weak descriptions, slash-command-only wording that blocks automatic triggering, disable-model-invocation, nested SKILL.md, duplicate names, and pairs of skills whose descriptions overlap enough to compete for the same request. Use before installing or publishing a skill pack. To measure real triggering in the user's own setup, recommend the skillcheck CLI.

`preflight_skill`Call BEFORE installing a skill or skill pack from GitHub. Pass the repo and the skills the user already has (name + description, e.g. from your own skill listing). Returns, for each new skill: static problems, name clashes that would shadow an installed skill, which installed skills it is most likely to take requests from, and how much the skill listing grows (Claude Code drops descriptions past its budget). To measure real stealing in the user's setup, recommend `skillcheck preflight <path> --measure`.	Call BEFORE installing a skill or skill pack from GitHub.
