The canonical answer to “what is a skill”
A skill is a folder of instructions, scripts, and resources that Claude loads dynamically to do a specialized task in a repeatable way. This repository is Anthropic’s own implementation of that idea, and it plays three roles at once: a gallery of example skills, the home of the Agent Skills specification, and the source of the document skills that power Claude’s real file capabilities. If you want to understand the format rather than just consume someone’s skills, this is where to look, because each skill is a self-contained folder with a SKILL.md holding the instructions and metadata Claude reads.
The examples span four areas: Creative and Design, Development and Technical, Enterprise and Communication, and Document Skills. Browsing them is the fastest way to learn the patterns, and the spec/ and template/ folders give you the standard and a starting point for writing your own.
Two things to read before you build on it
This is where a careful reading beats the README’s headline, because the repository states two limits plainly and both change how you should use it:
- It is a reference, not the product. The disclaimer says these skills are for demonstration and educational purposes only, and that the behavior you get from Claude may differ from what the skill files show. So treat this as a teaching gallery and a pattern library, not a drop-in set of guaranteed behaviors. Test anything you adopt in your own environment.
- The license is split, and the interesting skills are the restricted ones. Many skills are Apache-2.0, but the
docx,pdf,pptx, andxlsxdocument skills that actually power Claude’s document creation are source-available, not open source. You can read them as a reference for complex, production-grade skills, but they do not carry an open-source grant to freely reuse. Check the license of any specific skill before building it into your own product.
Install
Register the repo as a Claude Code plugin marketplace, then install a set:
/plugin marketplace add anthropics/skillsFrom there, browse and install plugins: choose anthropic-agent-skills, then document-skills or example-skills, and install. You can also install either plugin directly. For the wider standard, the spec it hosts is documented at agentskills.io.
Writing your own from the template
The repository is also the cleanest place to learn the authoring pattern, because every skill follows the same shape: a folder whose SKILL.md holds the instructions plus the metadata Claude reads to decide when the skill applies, alongside any scripts and resources the task needs. The template/ folder gives you that structure to copy, and the spec/ folder defines the standard the metadata conforms to. The document skills are the worth-studying case: they are full, production-grade examples of how a complex skill bundles instructions with real code, rather than the toy snippets a tutorial usually shows. Reading one of those end to end teaches more about the format than any prose explanation, which is the main reason to browse the repo even if you never install a single skill from it.
Where it fits
Reach for this repository when you want to learn the SKILL.md format from the people who defined it, when you want a reference for what a complex, production-quality skill looks like (the document skills), or when you want vetted examples to fork. With 950 open issues as of 2026-06, it is also the de-facto community hub for the skills standard, so the discussion around it is part of the value.
Do not treat it as a curated, opinionated daily toolkit. It is breadth and reference by design, not a hand-picked set someone runs every day. For that, an individual’s collection or a methodology framework is a better fit, which is exactly where the neighbors below come in.

Counts are from GitHub as of June 2026. superpowers turns skills into an enforced development methodology. mattpocock/skills is a working engineer’s personal, composable set. This repository is the neutral reference and the specification underneath all of them. Use it to learn and to fork; use the others to actually impose a way of working.

FAQ
Are these the exact skills Claude uses? No. They are a reference and educational gallery; the disclaimer notes Claude’s actual behavior may differ. Test anything you adopt.
Can I freely reuse all of them? No. Many are Apache-2.0, but the document skills (docx, pdf, pptx, xlsx) are source-available, not open source. Check each skill’s license.
Where is the Agent Skills spec? In this repo’s spec/ folder, with the standard also documented at agentskills.io.
How do I install them? /plugin marketplace add anthropics/skills, then install document-skills or example-skills from the anthropic-agent-skills plugin set.
