# RuleSkill

> A registry of Agent Skills: reusable instructions packaged as SKILL.md, discovered from public source repositories.

Skills are instructions and optional supporting files. Installing a skill does not configure an MCP server.
Version downloads preserve SKILL.md only. Review linked scripts and dependencies at the upstream repository before use.
