SKILL.md Template

The canonical SKILL.md template from Anthropic's official skills repo — frontmatter fields, trigger syntax, invocation patterns.

Entry verified April 20, 2026

The short answer

Anthropic's own reference. Start here before any community skill template — the spec changes, and Anthropic's repo is the source of truth.

When to use it

Before writing your first skill. When a community skill format doesn't work and you suspect it's out of date.

Setup

  1. 1

    Clone anthropics/skills and use their SKILL.md as your template.

  2. 2

    Keep it in sync — subscribe to the repo's releases.

  3. 3

    Reference inline in your /skill-creator setup.

Example

[Not invocable — reference material, copy the template into your skill file.]
