Antoskill

Antoskill is a local MCP package manager for Agent Skills that lets an assistant discover, vet and pin skills across Claude Code and Codex.

What you can do

Discover Agent Skills available for Claude Code and Codex through the package manager workflow described in the registry entry. Vet skills before adopting them, so an assistant can check what a skill does before it is used. Pin skills to fixed versions so the same setup is reproduced across tools. Optionally fetch skills from GitHub, using a token to raise the unauthenticated REST rate limit. No individual tools are listed in the manifest, so the exact operations are not documented here.

When to use it

Useful when you manage Agent Skills across both Claude Code and Codex and want a single way to find, review and lock them to specific versions. Less relevant if you only use one assistant or do not install third-party skills.

Requirements

Runs as a local stdio process installed from the npm package antoskill, so Node.js and npm are needed. Desktop only; no web-hosted version. Optionally set the GITHUB_TOKEN environment variable to lift the unauthenticated GitHub REST rate limit when fetching skills. No other authentication is declared.
