Skills Janitor

Tinder-style skill cleanup for Claude Code — swipe to delete, save context in seconds.

69/100MonitorFreeFree

Skills Janitor is a sharp utility for Claude Code power users who accumulate skills faster than they prune them. The swipe interface makes cleanup oddly satisfying, and the cross-scope duplicate detection is genuinely useful. Skip it if you have fewer than five skills or prefer a GUI — the CLI is fast but unfriendly to non-developers.

Best for
  • Claude Code power users with many installed skills
  • Developers practicing AI agent prompt hygiene
  • Teams sharing skill repositories who need deduplication
  • Freelancers seeking to minimize context costs
Not ideal for
  • Users who rely exclusively on GUI-based tools
  • Non-developers unfamiliar with command-line interfaces
  • Those looking for cloud-hosted skill management

About Skills Janitor

FreeIntermediateNo APICLI

Skills Janitor is a free, open-source CLI tool for Claude Code and OpenAI Codex users drowning in skill bloat. It turns your installed skill collection into a Tinder-style swipe deck (v1.4+), sorted by heaviest-and-least-used first, so you can delete what's wasting context in seconds. Most users clear 30–40% of their skill token cost per session. Beyond swiping, the tool audits inventory, detects cross-scope duplicates (user/project/codex/plugin), fixes broken symlinks and empty directories, and shows honest token costs for always-loaded descriptions vs. on-demand bodies. It runs locally with zero dependencies—just Bash, Python 3, and curl—and supports natural language queries like "check my skills" or "which skills are wasting context?" Commands include /janitor-report (health check), /janitor-fix (auto-fix), /janitor-value (token+usage tracker), /janitor-discover (GitHub search/URL precheck), and /janitor-swipe (interactive TUI). The tool is MIT licensed and fully offline-capable. It works exclusively with Claude Code and OpenAI Codex—not other AI coding assistants. If you have more than a handful of skills, this is the fastest way to reclaim context window space without manual hunting.

Behind the Verdict

Skills Janitor solves a very specific, very real pain: skill bloat in Claude Code and OpenAI Codex. If you've ever wondered why your context window feels tight despite a modest skill count, this tool will surface duplicates, unused rules, and token weight you didn't know you had. The swipe mechanic is a clever UX choice for a CLI — it turns a chore into a quick triage. Where it bites: you need to be comfortable at the command line, and it only works with Claude Code and Codex. If you use GitHub Copilot or Cursor, this isn't for you. Compared to manual cleanup (ggrep through skill files), Skills Janitor is orders of magnitude faster — especially with cross-scope detection that v1.3+ added. The v1.5 release also removed old v1.2 aliases, so you must use the new commands or check the changelog. Also, plugin skills can only be flagged, not individually deleted — a real limitation if a plugin installs five skills you only want two. Still, for anyone actively maintaining a skill-heavy Claude setup, this is a no-brainer grab.
