About

Skills on AI is a catalog of 1135 Claude Code skills, organized into 76 categories. Each skill is a single SKILL.md file that an AI coding agent can load on demand — reference material covering a specific topic (a testing technique, a cloud platform, a database engine, a project-management framework, a diagram type, and more) with clear trigger conditions for when it applies.

What a skill looks like

Every SKILL.md file has the same shape: YAML frontmatter naming the skill and describing when to use it, followed by a Markdown body — a short introduction, a few focused sections covering the topic's key concepts, a "Common pitfalls" list, and a "Learn more" section linking to related skills in the catalog and, where relevant, external references.

How the catalog stays consistent

The skills directory, this website, the root README.md, and a compact spec/index.md manifest are kept in sync with each other — every skill appears in all of them, under the same name, with no gaps in either direction. The site data, plus llms.txt and llms.json for AI agents, are generated from the skill files, never edited by hand. Any skill's raw file is available at /skills/<name>/SKILL.md.
