What is a Claude Code Skill?

A Claude Code Skill is a modular package that extends Claude's capabilities with specialized knowledge, workflows, and tools tailored to specific domains or tasks.

What is Progressive Disclosure in skill design?

It is a design principle that manages context by loading information in stages: first metadata, then the SKILL.md body, and finally specific resources only when Claude determines they are needed.

When should I use a script versus a reference file?

Use scripts for tasks requiring deterministic reliability or repeated code execution. Use reference files for documentation, schemas, or domain knowledge that Claude should read to inform its logic.

Why is 'Concise is Key' a core principle?

Conciseness preserves the context window, which is a shared resource. Efficient skills ensure Claude has enough room for conversation history and actual task execution without wasting tokens.

What are the core components of a skill?

Every skill requires a SKILL.md file containing YAML frontmatter and markdown instructions. It can also include optional bundled resources like scripts, references, and assets.
