A skill is a single markdown file (SKILL.md) that gives Claude Code domain-specific knowledge, a structured workflow, and clear output expectations. Drop the file into ~/.claude/skills/ and Claude loads it on demand — invoked by slash command or by natural-language match against the description.
Every skill in this repository follows the same standard format (see Standard skill format) so they're easy to learn, easy to compose, and easy to extend.
