Individual skill
skill-checkup
Read-only checkup of installed agent skills across Claude Code and Codex: broken links or files, same-name copies that drifted apart, descriptions that compete or miss requests their skill already handles, and skills loaded by both agents but used by only one. Use when the user asks to check, audit or tidy their skills, compare Claude Code and Codex skills, asks why a skill did not trigger, or wants to test a reworded description against past requests. For unused Claude Code skills and token cost alone, Claude Code's /skill-doctor is enough. Not for agent config health or raw usage rankings (skill-usage-stats) or policy-driven ownership, exposure and retirement repairs (skill-ecosystem-doctor).

# Skill Checkup
A thin entry point for [skill-checkup](https://github.com/majiayu000/skill-checkup), a
read-only, offline Python tool with no dependencies. It reads installed skill folders
(`~/.claude/skills`, `~/.agents/skills`, `~/.codex/skills`, the current project's
`.claude/skills` and `.agents/skills`, and enabled Claude Code plugins) and local Claude
Code and Codex session logs.
## Operating Contract
- Direct actions: run the checkup, summarize it, and explain the top actions.
- Escalate before: editing, merging, moving or archiving any skill. The tool never does this; only change a skill when the user names that change.
- Evidence-backed pushback: similarity findings and the silent appendix are lexical matches over past requests. Present them as candidates, not verdicts, and check one or two by reading the skill before recommending a change.
- Feedback loop: after an approved wording change, rerun `replay` for that skill and report both rows.
