To use a skill:
- Clone the Anthropic Claude Skills repo.
- Enable Code Execution and Skill loading in Claude.
- Upload the skill folder (or link to a Git repo with an
SKILL.md). - Ask Claude to activate or use the skill!
Writing a great skill starts with a well-structured SKILL.md file. AgentSkills.io provides the canonical specification for the Claude Skills format, including validation rules and a detailed checklist. Anthropic also publishes best practices for skill authoring at platform.claude.com.
Every skill should include a SKILL.md with proper YAML frontmatter at the top:
---
name: my-skill-name
description: |
Generates weekly status reports from project data.
Use when the user asks for a summary of recent activity.
---The body of SKILL.md (below the frontmatter) contains the instructions Claude follows when the skill is activated.
- name -- Use
kebab-case, 1-64 characters (e.g.,csv-data-summarizer, notCSV Data Summarizer). - description -- Write in third person. State what the skill does and when to use it. Keep it under 300 characters.
- Body length -- Keep the instruction body under 500 lines. Long skills should be split into focused sub-skills.
- Progressive disclosure -- Start with the most common usage, then cover edge cases. Claude reads top-down, so put the critical path first.
- No secrets in source -- Never embed API keys, tokens, or credentials in
SKILL.md. Use environment variables or MCP configuration instead.
- anthropics/skills -- Anthropic's official skill repository with production-quality examples.
- AgentSkills.io Validation Checklist -- Use this to validate your
SKILL.mdbefore publishing. - Anthropic Skill Authoring Guide -- Official best practices from Anthropic.
