Skill creator
Anthropic's own tool for writing a new skill in the format agents actually load.
Installation
$ npx skills add anthropics/skillsThe CLI's unit is the repository, so this installs everything in anthropics/skills, not skill-creator alone. It writes into whichever agent directories it finds — Claude Code, Codex, Cursor, Copilot, Windsurf, Zed.
Summary
Anthropic's own tool for writing a new skill in the format agents actually load.
- Reach for it when you have internal knowledge worth encoding and want it to match the house format.
- Sits in Working with skills — finding skills, writing your own, and keeping a skill library from turning into a junk drawer.
- Stack-agnostic — nothing in it assumes a particular language or framework.
- Published by Anthropic, who ship the thing it is about — a stronger claim than a well-regarded engineer having written something good.
- Installing pulls the whole anthropics/skills repository: this catalogue lists 3 other entries from it, and the repo may hold more.

The agent itself
The full text lives with its publisher and changes when they change it. Read it there rather than here — a mirrored copy of somebody else's procedure goes stale silently, and this page would have no way of telling you.
