Open-source tool. Self-hosted setup.
This is Anthropic's own reference collection for the Agent Skills format — the SKILL.md convention that much of the rest of this ecosystem builds on. It doubles as living documentation: the examples here define what a well-formed, portable skill looks like for Claude and other coding agents.
Things to Know About Self-Hosted
