Read-only checkup of the agent skills installed on this machine: which are broken (dead links, missing files or commands, diverged copies), competing for the same requests, heavy on Claude Code's skill-listing budget, or unused, plus repeated requests no skill covers and descriptions that miss what their skill already handles. Use when the user asks to check, audit or tidy their skills, asks why a skill did not trigger, or wants to test a reworded description against past requests. Not for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. ## Run From the user's current project, so project-level skills are included: ```bash uvx --from git+https://github.com/majiayu000/skill-checkup@v0.1.1 skill-checkup ``` …

How to install
mdr add majiayu000/spellbook/skill-checkup@sha256:28c9d5a6cb8271adThe line at the top of this page pins the label git:20261023.bd4c5d3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
