What are the requirements for the SKILL.md frontmatter?

The name must be lowercase with hyphens only (max 64 chars) and match the directory name. The description must be under 1024 characters and include both what the skill does and when to use it.

What is a Claude Code Skill?

A Claude Code Skill is a specialized capability that enhances Claude's behavior by providing domain-specific guidance, best practices, and implementation patterns for specific tasks.

Why isn't my skill activating in Claude Code?

Activation issues are usually caused by vague descriptions. Ensure your description includes specific 'Use when...' clauses, file extensions, and trigger words that match user queries.

Where should I store my custom skills?

Personal skills should be placed in ~/.claude/skills/, while project-specific skills intended for team use should be stored in .claude/skills/ within your project root.
