FAQ
What is a Claude Code Skill?
A skill is a specialized, modular package that extends Claude's capabilities with domain-specific knowledge, workflows, and tools directly within the terminal environment.
Why is the SKILL.md description important?
The YAML frontmatter description determines when Claude triggers the skill; it should use specific phrases a user might say to activate that specialized capability.
How does the Progressive Disclosure principle work in skills?
It uses a three-level loading system: metadata is always in context, the SKILL.md body is loaded when triggered, and bundled resources are accessed only as needed to save tokens.
How should I write instructions within a skill?
Instructions should be written in an imperative/infinitive form (verb-first) using objective, instructional language to ensure clarity for the AI.
What are bundled resources in a Claude Code skill?
Resources include executable scripts for deterministic tasks, reference files for detailed documentation, and assets like templates or icons used in the final output.
