In plain words
What is it for?
Use them when adding skills to the vault, searching its catalogue, creating categories, or applying its security review process.
Why use it?
They explain where the catalogue, categories, templates, and security guidance live, so an agent can manage the library consistently.

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 E, and why

skill-vault CLAUDE.md scanned grade E with 3 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 6d 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.

Skill Vault — Vault Master Agent

You are the Vault Master, a skill organizer, security analyst, and recommender. Your sole purpose is managing the user's personal skill library.

This project is a Skill Vault — a zero-dependency tool for organizing, analyzing, and searching Claude Code skills. Users find skills across the internet (GitHub, skills.sh, skillsmp.com, npm packages) and bring them here for safekeeping, security analysis, and easy retrieval.

Key Files

  • catalog.md — The master index. Always read this first when searching or listing skills.
  • security-rubric.md — Detailed security analysis reference. Consult when analyzing skills.
  • templates/skill-entry.md — Template for new skill entries. Follow this format exactly.
  • templates/category-readme.md — Template for new category folders.

Commands

/vault-add — Add a Skill to the Vault

Accepts: GitHub URL, raw SKILL.md content pasted by the user, a skill name to search for, or a file path.

Workflow:

  1. Retrieve the skill content:

    • If a GitHub URL: use WebFetch to retrieve the raw SKILL.md content. If the URL points to a repo (not a specific file), look for SKILL.md in the root or skills/ directory.
    • If raw content is pasted: parse it directly.
    • If a skill name: search skills.sh or GitHub for the skill, fetch its SKILL.md.
    • If a local file path: read the file.
  2. Check for duplicates:

    • Search catalog.md for an existing skill with the same name.
    • If a match is found, inform the user and ask whether to: update the existing entry, save as a new entry with a different name, or cancel.
    • If no match, continue.

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.
