Skill auditing
Creates an inventory of skills and flags duplicates, broken symlinks, and other clutter across user, project, codex, and plugin-installed skills.
Skills Janitor
Skills Janitor is a GitHub-hosted set of slash commands for auditing, tracking, and managing Claude Code and OpenAI Codex skills. It helps users find duplicates, broken links, and unused skills, then clean them up with self-contained commands.
Overview
Skills Janitor is a GitHub repository that packages slash commands for auditing, tracking, and managing Claude Code and OpenAI Codex skills. Its documented purpose is to help users inspect where skills live, identify duplicates or broken symlinks, and clean up unused items that add noise to the working context.
The project is organized around self-contained skill folders and scripts, with installation paths for both Claude Code plugin workflows and direct cloning. The README also says it has zero dependencies, with Bash, Python 3, and curl as the stated runtime requirements.
Core capabilities
Repair and cleanup
Runs automatic cleanup actions, including pruning broken symlinks and empty directories when requested with the fix command.
Usage and value view
Surfaces token and usage waste in a combined view so you can sort skills by cost or clutter instead of manually checking each one.
Skill discovery
Lets you search GitHub for skills or validate a URL before installing, which fits the discover-then-install workflow.
Cross-tool compatibility
Supports both Claude Code and OpenAI Codex, with each command packaged as a self-contained `SKILL.md` plus a sibling script.
Backward-compatible command set
Tracks the v1.2 to v1.3 command renames and keeps the older commands available as deprecated aliases for a transition period.
Common use cases
Audit an existing skills setup
Run a health check to inventory skills, spot duplicates, and surface broken symlinks before they create confusion in your workspace.
Clean up stale or invalid skills
Use the fix workflow to prune broken links and empty directories after you have identified clutter that should be removed.
Review skill usage and waste
Compare token and usage waste across skills to decide which ones should stay active and which ones should be consolidated.
Discover and vet new skills
Search GitHub for a skill or verify a URL first when you want to install something new with less guesswork.
Adopt the newer command set
Migrate from older command names by following the documented v1.2 to v1.3 renames while keeping deprecated aliases working during the transition.
Pros and Cons
