What are the different complexity tiers for skills?

Skills can range from 'Simple' (SKILL.md only) to 'Full' (including references for domain knowledge, scripts for automation, and assets for templates).

How do I validate a new skill I created?

You can use the built-in validation step which uses the quick_validate.py script or the upstream skills-ref tool to check for formatting and naming errors.

Can I include external dependencies in my skill scripts?

Yes, scripts used within skills should include PEP 723 inline metadata to manage dependencies and be executed using the 'uv run' command.

What is a Claude Code Skill?

A Claude Code Skill is a specialized capability, defined in a SKILL.md file, that provides domain-specific guidance and patterns to help Claude perform tasks more effectively.

Why is the skill description so important?

The description acts as the primary trigger mechanism. It must include natural language keywords that the agent uses to match the user's intent to the skill's capabilities.
