To create and package Claude skills, you scaffold a new skill using initialization templates, populate resources like scripts and references, and bundle the output into a distributable .skill file for sharing.

The required YAML frontmatter contract for a valid skill file mandates specifically name and description fields, while also supporting optional license and progressive disclosure metadata for extended configuration.

Yes, you can update existing Claude skills by applying the provided validation and resource organization tooling, which ensures your current frontmatter and bundled assets meet the required structural contract.

The best way to organize reusable scripts and references is to bundle them within the skill's optional resources directory, ensuring predictable automation and seamless packaging into the final distributable unit.

Packaging a skill relies on internal validation dependencies like yaml and quick_validate scripts, which automatically enforce the required frontmatter contract before generating the final distributable file.

Your Claude skill fails validation during initialization when the SKILL.md file is missing mandatory frontmatter fields, specifically the required name and description keys defined in the YAML contract.
