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

claude-skills CLAUDE.md scanned grade A with 0 findings 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 22d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude Skills

Repository: https://github.com/jezweb/claude-skills Owner: Jeremy Dawes (Jez) | Jezweb

Production workflow skills for Claude Code CLI. Each skill guides Claude through a recipe to produce tangible output: working deliverables, not knowledge dumps.

Philosophy

  • Every skill must produce visible output (files, configurations, deployable projects); reference material Claude already knows does not earn a place.
  • "The context window is a public good": only include what Claude doesn't already know.
  • Teach patterns, not ship scripts: skills teach Claude what to do, and Claude generates scripts adapted to the user's environment. Pre-built scripts in scripts/ are the rare exception; proven implementation patterns go in references/ for Claude to adapt.
  • Follow the official Claude Code plugin spec.

Layout

plugins/<plugin>/skills/<skill>/, one folder per plugin and skill; .claude-plugin/ holds marketplace.json and plugin.json; README.md is the public overview; LICENSE is MIT. The folders are the truth, so this file lists no plugins, skills or counts. A plugin carries .claude-plugin/plugin.json (name, description, author) and auto-discovers its skills/; the skill folder layout is SKILL_SHAPE.md "Multi-file layout".

Adding a New Plugin

  1. mkdir -p plugins/my-plugin/{.claude-plugin,skills}
  2. Create .claude-plugin/plugin.json:
    {
      "name": "my-plugin",
      "description": "What this plugin does.",
      "author": { "name": "Jeremy Dawes / Jezweb", "email": "[email protected]" }
    }
    
  3. Add skills inside plugins/my-plugin/skills/, each with SKILL.md.
  4. Add an entry to .claude-plugin/marketplace.json:
    { "name": "my-plugin", "description": "...", "source": "./plugins/my-plugin", "category": "development" }
    
  5. Update the table in README.md.

Categories: development, design, productivity, testing, security, database, monitoring, deployment

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.
