skills-auditAudits a project's .agents/skills folder for duplicate, overlapping, stale or broken skills and suggests merge or delete candidates, weekly or after skill changes.
The skill is a periodic review of project-local skills so the catalog does not drift into confusion. It recommends a weekly cadence, or a review after any week in which more than one skill was added or renamed. Step one builds an inventory that includes symlinked skills, reusing helpers in package.json scripts or .agents/scripts when they exist and otherwise using find commands for the count and body lengths, grouping skills by domain and noting recent additions from the git log.
Step two looks for overlap: identical descriptions, tasks that fit several descriptions, see-also references to skills that no longer exist, and content duplicated from AGENTS.md. It lists common false positives that should not be merged, such as db-migrations versus drizzle. Step three checks that each description states the skill's purpose and boundary clearly, matches its body, and avoids broad triggers or stale names.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 31b02b5. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
rggitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Skills Audit loads about 1.7k tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 813 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 813 words (~1,718 tokens).
“Periodic review of the project-local skill set under .agents/skills/. The goal is to catch drift before the catalog becomes confusing — too many skills, overlapping triggers, descriptions that no longer match the body, references to skills that were renamed/deleted.”

Audits a project's .agents/skills folder for duplicate, overlapping, stale or broken skills and suggests merge or delete candidates, weekly or after skill changes. The skill is a periodic review of project-local skills so the catalog does not drift into confusion. It recommends a weekly cadence, or a review after any week in which more than one skill was added or renamed.
Skills Audit fits situations like: running a weekly check on a project's skill catalog; finding skills with duplicate or overlapping descriptions; cleaning up cross-references to renamed or deleted skills.
Run `npx skills add lobehub/lobehub --skill skills-audit -a claude-code`. Or copy the skill folder (.agents/skills/skills-audit in lobehub/lobehub) into .claude/skills/skills-audit in your project. Claude Code loads it when a task matches its description.
Run `npx skills add lobehub/lobehub --skill skills-audit -a codex`. Or copy the skill folder (.agents/skills/skills-audit in lobehub/lobehub) into .agents/skills/skills-audit in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add lobehub/lobehub --skill skills-audit -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skills-audit, .gemini/skills/skills-audit, .github/skills/skills-audit and .opencode/skills/skills-audit in your project.
Going by SKILL.md and its folder, Skills Audit needs the command-line tools its instructions call (rg and git). Our summary lists: A project with a .agents/skills folder.
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Skills Audit has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
