How does Claude know when to load a specific skill?

Claude uses the 'description' field in the skill's YAML frontmatter, which should contain specific trigger phrases that match user requests.

Can I automate the review of my Claude skills?

Yes, this skill recommends using the 'skill-reviewer' agent to check for trigger quality, word count, and adherence to the imperative writing style.

What is the purpose of the SKILL.md file?

The SKILL.md file acts as the primary instruction set for a Claude Code skill, containing the logic, triggers, and frontmatter required for Claude to execute specific tasks.

What is progressive disclosure in skill development?

It is a best practice of keeping the core SKILL.md file under 1,500 words and moving detailed API docs or long-form content into a separate 'references/' directory to save context space.

Developer Tools

Standardizes the creation of Claude Code skills by providing structured templates, frontmatter guidance, and progressive disclosure patterns.

This skill serves as the definitive guide for developers building functional extensions for Claude. It provides a structured framework for creating SKILL.md files, defining trigger-based frontmatter, and implementing progressive disclosure strategies to keep AI instructions concise yet powerful. By following these patterns, developers can ensure their skills are auto-loaded correctly, maintain high code quality through the skill-reviewer agent, and organize complex documentation into manageable references and examples.
