FAQPage Schema
How do skills activate and load instructions?

Skills activate by loading their instruction set from frontmatter metadata, enforcing tool restrictions defined in SKILL.md, and progressively disclosing information based on activation criteria. The hello-world skill demonstrates this process end-to-end.

What does skill structure and composition mean?

Skill structure defines how a skill organizes its components, documentation, and tool permissions. Composition means skills work alongside others to expose outputs. Hello-world shows both through its frontmatter, notes, and references.

Can I use skills for testing and demonstration purposes?

Yes, skills apply to testing and demonstration contexts including initial activation, dynamic instruction loading, and tool-permission testing. Hello-world is designed specifically for this use case.

How do I understand skill activation criteria and tool restrictions?

Activation criteria and tool restrictions are defined in SKILL.md metadata. Hello-world demonstrates how these enforce permissions during skill loading and runtime, making them visible and testable.

What's the best way to onboard to Claude skills?

Use a demonstration skill to explore basic structure, activation flow, and how documentation guides tool access. Hello-world provides a simple foundation for understanding these core concepts.
