Skills

Agent Skills are folders of instructions, scripts and resources that Claude loads when a task calls for them. One skill teaches one job done the same way every time: writing documents against a company's brand guidelines, analyzing data through an organization's own workflow, automating a personal routine. Each is self-contained around a SKILL.md file whose YAML frontmatter requires only two fields, a name and a description, followed by the instructions Claude reads.

This is Anthropic's public repository of them. The bundled examples reach from creative work such as algorithmic art through development tasks such as MCP server building and web app testing to enterprise communication, and the Agent Skills specification and a starter template ship alongside. Many are open source under Apache 2.0, while the docx, pdf, pptx and xlsx skills behind Claude's document features are source-available instead, included as a reference for more complex production skills. The repository registers as a Claude Code plugin marketplace offering document-skills and example-skills, the example skills already reach paid Claude.ai plans, and custom skills upload through the Claude API. Anthropic labels the whole collection demonstration material, which is a reason to try a skill before letting real work depend on it.
