Install

Skills CLI

npx skills add khendzel/skills-janitor

Asks which skills and agents to install. Just one: npx skills add khendzel/skills-janitor --skill janitor-discover — add -g for every project.

Claude Code

git clone https://github.com/khendzel/skills-janitorcp -r "skills-janitor/skills/janitor-discover" ~/.claude/skills/

Copies the janitor-discover skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add khendzel/skills-janitor

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • 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'.

    skills/janitor-discover/SKILL.md on GitHub (opens in a new tab)

  • 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'.

    skills/janitor-fix/SKILL.md on GitHub (opens in a new tab)

  • 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'.

    skills/janitor-report/SKILL.md on GitHub (opens in a new tab)

  • 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'.

    skills/janitor-security/SKILL.md on GitHub (opens in a new tab)

  • 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'.

    skills/janitor-swipe/SKILL.md on GitHub (opens in a new tab)

  • 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'.

    skills/janitor-value/SKILL.md on GitHub (opens in a new tab)

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
