Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01640 |
| Opus 5.5 | $0.00023 | $0.00656 |
| Sonnet 5.5 | $0.00012 | $0.00328 |
| Haiku 4.5 | $0.00006 | $0.00164 |
Grade A, and why
janitor-discover scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
compatibility: Designed for Claude Code. Requires bash 3.2+, curl, and network access to the GitHub API (anonymous works; GITHUB_TOKEN raises rate limits). How it starts
The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Discovery & Pre-Install Check
Combined entry point for finding skills on GitHub and for evaluating a specific skill (URL or local path) before installing it.
Overview
Replaces the v1.2 split between /janitor-search and /janitor-precheck. The dispatcher picks the right mode from the argument shape. Search results are relevance-gated (a repo must carry a skill signal in its name/description/topics) and ranked by relevance before stars, so generic mega-repos don't crowd out actual skills.
| Argument | Mode | What runs |
|---|---|---|
Keyword(s) like seo or n8n workflows |
Discovery | search.sh — find matching skills on GitHub |
--compare <skill-name> |
Comparison | search.sh --compare — find alternatives to a local skill |
Full URL: https://github.com/user/skill |
Pre-install check | precheck.sh — analyze before installing |
Short repo: user/skill |
Pre-install check | precheck.sh (auto-expanded to URL) |
Local path: ~/path/to/skill |
Pre-install check | precheck.sh (local folder) |
Pre-install mode runs two checks, not one: overlap against what's already installed, and
(since v1.6) a security scan of the candidate via security.sh — the same heuristics
/janitor-security uses on installed skills.
Prerequisites
- Claude Code with the skills-janitor plugin installed (provides
scripts/discover.sh,search.sh,precheck.sh,compare.sh) - bash 3.2+ and
curl - Network access to
api.github.com(anonymous OK; setGITHUB_TOKENfor higher rate limits and code search)
Instructions
Step 1: Dispatch on argument shape
bash ~/.claude/skills/skills-janitor/scripts/discover.sh <query-or-url> [options]
Examples:
discover.sh seo— search for SEO-related skillsdiscover.sh n8n --limit 20— top 20 n8n skillsdiscover.sh --compare marketing-seo-audit— alternatives to a local skilldiscover.sh https://github.com/user/my-skill— check before installingdiscover.sh user/my-skill— same, short form
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
- 1mo ago First seen · 124 lines · 58 tokens per session scan A 68c000d94d30
janitor-discover is a skill published in the GitHub repository khendzel/skills-janitor (122 stars, last pushed 26d ago), licensed MIT. It adds 58 tokens to every session and 1,640 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
