Audit, design, categorize, distribute, and measure agent skills using lessons from Anthropic's Lessons from building Claude Code: How we use skills. Use when reviewing an existing skill, deciding whether a workflow deserves a skill, planning a skill library, turning team knowledge into skills, choosing skill categories, writing trigger descriptions, designing progressive disclosure, or planning skill marketplace and usage measurement.
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 Audit Use this skill to audit existing skills, turn workflow knowledge into useful agent skills, and review skill libraries at the strategy level. It complements `skill-creator`: use this skill to decide what a skill should be, how it should fit a library, and what needs improvement; use `skill-creator` when the user wants the concrete SKILL.md implementation and eval loop. This workflow is based on Anthropic's June 3, 2026 blog post, "Lessons from building Claude Code: How we use skills": https://claude.com/blog/lessons-from-building-claude-code-how-we-use-skills ## Core Principle A good skill is not "some markdown about a topic." It is a compact extension point that gives the agent non-obvious domain knowledge, reusable files, deterministic helpers, setup rules, verification habits, and guardrails at the moment they matter. ## Workflow ### 1. Decide Whether This Should Be A Skill Create or improve a skill only when at least one of these is true: - The workflow repeats often enough that users should not re-explain it. - The agent regularly makes the same domain-specific mistake. - The work needs local scripts, templates, examples, assets, hooks, or setup. …

How to install
mdr add majiayu000/spellbook/skill-audit@sha256:5447230292ae0057The line at the top of this page pins the label git:20260705.94ad48d, 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.
