How do trigger phrases work in skill descriptions?

Trigger phrases in the YAML frontmatter description help Claude identify exactly when a skill should be activated based on specific user query patterns.

What is a Claude Code Skill?

A Claude Code Skill is a modular package that provides specialized knowledge, workflows, and tools to Claude, allowing it to perform domain-specific tasks with higher reliability.

When should I use scripts versus references in a skill?

Use scripts for executable tasks that require deterministic results or token efficiency. Use references for large documentation, schemas, or policies that Claude should consult to inform its reasoning.

What is the principle of progressive disclosure in skills?

It is a three-level loading system (Metadata, SKILL.md, and Resources) designed to keep Claude's context window lean by only loading detailed information when it is specifically needed for a task.

Guides developers through creating, structuring, and optimizing modular skills to extend Claude's domain-specific capabilities.

This skill provides a standardized framework for building high-quality Claude Code skills, transforming Claude from a general-purpose agent into a specialized expert. It details the modular anatomy of a skill—including metadata, executable scripts, reference documentation, and static assets—while teaching the principle of progressive disclosure to maximize context window efficiency. By following this structured development process, developers can implement complex workflows, integrate specialized tools, and maintain lean, high-performance plugin environments.
