Skills Janitor

Skills Janitor is an open-source plugin for Claude Code that keeps your skills ecosystem clean, organized, and healthy. It provides 9 dedicated slash commands — each a self-contained skill — covering everything from auditing installed skills to searching GitHub for new ones. The tool requires only Bash, Python 3, and curl, with no pip installs or node modules needed.

• /janitor-audit — lists all installed skills in a full inventory view
• /janitor-duplicates — identifies duplicate skills that perform the same function
• /janitor-check — scans skills for errors and missing metadata
• /janitor-fix — automatically repairs skill problems with a safe dry-run preview first
• /janitor-cleanup — finds and removes broken or invalid skills
• /janitor-report — generates a full health check report across all skills at once
• /janitor-usage — parses conversation history to show which skills you actually invoke vs. never use
• /janitor-search — searches GitHub for new Claude Code skills by keyword
• /janitor-compare — compares your skill against similar alternatives found on GitHub
• Natural language triggers — skills also activate from keywords in their descriptions, so you can type "audit my skills" instead of a slash command
• Safe-by-default operations — all destructive actions require explicit confirmation and run in dry-run mode by default; plugin/marketplace skills are never modified
• Usage tracking — shows active vs. unused skills over a configurable time window with recommendations to remove dead weight
• Zero dependencies — install via the Claude Code plugin marketplace or by cloning directly; no package managers required
