What is the difference between Personal and Project skills?

Personal skills are stored in your home directory for individual use, while Project skills are stored in the local project directory and are typically committed to version control for team sharing.

What is a Claude Code Skill?

A Claude Code Skill is a specialized capability, defined in a SKILL.md file, that provides domain-specific instructions and best practices to enhance Claude's behavior for specific tasks.

What file format is required for a Claude Code Skill?

Every skill requires a directory containing a SKILL.md file with valid YAML frontmatter at the top, followed by markdown instructions for the AI.

How do I make my custom skill easier for Claude to find?

Discovery depends on the description in the YAML frontmatter. Use a formula of [What it does] + [When to use it] + [Key triggers] to ensure Claude activates the skill on relevant queries.

Can I limit the tools Claude uses within a specific skill?

Yes, you can use the 'allowed-tools' field in the SKILL.md frontmatter to restrict Claude to specific operations, such as making a skill read-only.
