Agent Skills (Anthropic)

What it does

Anthropic's public repository of Agent Skills: folders with a SKILL.md file (plus optional scripts and resources) that Claude loads when a task needs them. It includes example skills, the document skills behind Claude's file creation, a skill template and a copy of the Agent Skills spec (the open standard lives at agentskills.io). Many skills are Apache-2.0; the document skills are source-available, not open source.

Who it's for

Claude Code and Claude.ai users who want ready-made skills, or a starting point to write their own. Anthropic says the example skills are already available on paid Claude.ai plans.

How to set it up

1. In Claude Code, add the repo as a plugin marketplace:

   textCopy

   /plugin marketplace add anthropics/skills

2. Then install a skill set:

   textCopy

   /plugin install document-skills@anthropic-agent-skills
   /plugin install example-skills@anthropic-agent-skills

3. To write your own, make a folder with a SKILL.md that has a name and description in its YAML frontmatter:

   markdownCopy

   ---
   name: my-skill-name
   description: What this skill does and when to use it
   ---
   # My Skill Name
   Instructions Claude should follow...

4. The repo says these skills are for demonstration and education; behavior in Claude may differ.
