Skills Janitor

Inspect Skill context costs, duplicates, security, and MCP usage.

The six-command pack helps Claude Code and Codex users triage installed capabilities, including interactive keep/delete decisions and duplicate detection.

Use cases

• Find unused or duplicate installed Skills
• Review Skill and MCP security

How to use

Install the pack and review findings before removing an entry. The author marks the project in maintenance mode because newer host tools cover part of the workflow.

Skills

• janitor-discover

  Find new skills on GitHub or check a specific skill before installing. Use when the user wants to search for skills, evaluate a skill URL, check overlap and security risk before installing, or compare a local skill against alternatives. Trigger with '/janitor-discover'.

  khendzel/skills-janitor

• janitor-fix

  Automatically fix skill problems (safe preview first). Also use with --prune to find and remove broken symlinks, empty directories, and orphaned skills. Trigger with '/janitor-fix'.

  khendzel/skills-janitor

• janitor-report

  Full health check of all your skills in one report. Use when the user wants to check for errors, find duplicates, detect broken skills, or get a complete overview of skill health. Pass --brief for inventory only. Trigger with '/janitor-report'.

  khendzel/skills-janitor

• janitor-security

  Heuristic security scan of installed skills — prompt-injection phrases, hidden unicode instructions, credential-store access, network-pipe-to-shell and payload-smuggling patterns. Use when the user asks 'are my skills safe', wants to scan skills for prompt injection or malware patterns, or before trusting a newly installed skill. Trigger with '/janitor-security'.

  khendzel/skills-janitor

• janitor-swipe

  Tinder for your Claude Code skills. Reviews a sorted deck of every installed skill and lets you swipe keep / delete / skip on each one. Use when the user wants to bulk-clean their skill collection, triage unused skills, or do interactive skill cleanup. Trigger with '/janitor-swipe'.

  khendzel/skills-janitor

• janitor-value

  Show whether each skill is earning its context-window cost — combined tokens-used view sorted by waste. Use when the user asks 'are my skills worth it', 'what's my context budget', 'which skills are dead weight', or wants to audit skill value, token cost, or usage. Trigger with '/janitor-value'.
