Token cost

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.

Security

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 11d 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.

compatibility: Designed for Claude Code. Requires bash 3.2+, curl, and network access to the GitHub API (anonymous works; GITHUB_TOKEN raises rate limits).

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; set GITHUB_TOKEN for 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 skills
  • discover.sh n8n --limit 20 — top 20 n8n skills
  • discover.sh --compare marketing-seo-audit — alternatives to a local skill
  • discover.sh https://github.com/user/my-skill — check before installing
  • discover.sh user/my-skill — same, short form

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.
