What is the recommended length for a SKILL.md file?

A main SKILL.md file should be kept concise, ideally under 500 lines, with more detailed content moved to the references directory.

What is a Claude Code Skill?

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

Do I need to restart Claude Code after creating a skill?

No, skill changes take effect immediately because Claude Code supports hot-reloading for custom skills.

How do I ensure my skill is easily triggered?

Include specific trigger phrases in the YAML frontmatter description, such as 'This skill should be used when the user asks to...', to help Claude identify when to activate it.

Streamlines the creation and optimization of custom Claude Code skills by enforcing structured documentation and Anthropic best practices.

This skill provides a comprehensive framework for extending Claude Code's capabilities through the development of specialized skills. It assists developers in drafting effective SKILL.md files, generating compliant YAML frontmatter, and organizing complex technical content using the progressive disclosure pattern. By enforcing structural constraints such as file length limits and third-person perspectives, it ensures that new capabilities remain concise, discoverable, and immediately functional through hot-reloading without requiring a system restart.
