What are the core components of a skill structure?

A skill consists of a required SKILL.md file with YAML frontmatter, and optional subdirectories for executable scripts, reference documentation, and static assets.

What is a Claude Code Skill?

A Claude Code Skill is a specialized, modular capability that provides Claude with domain-specific knowledge, tools, and workflows to perform complex tasks more effectively.

How does this skill improve context window management?

It implements the 'Progressive Disclosure' principle, teaching you to move large reference materials and assets into secondary files that Claude only loads when specifically needed.

Why are trigger phrases important in the description?

Trigger phrases in the YAML frontmatter act as the primary signal for Claude to activate the skill; they must match the specific language and intent a user would express.
