What is a Skill?

A Skill is a folder with a SKILL.md file — instructions, scripts, and resources that Claude loads on demand to do a specialized task in a repeatable way. Claude reads the description, decides when it's relevant, and pulls in the full instructions only when needed.

# Official marketplace (recommended)
/plugin marketplace add anthropics/skills
/plugin install document-skills@anthropic-agent-skills

# Or via the npx skills manager (vercel-labs/skills)
npx skills add https://github.com//

# Or drop a skill folder in manually
git clone  ~/.claude/skills/

In Claude.ai (paid plans) and the API you upload skills in Settings / via the Skills API. See the official spec.
