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.
