creating-skills

To create a Claude Skill, run the Skill Initializer to bootstrap a new project, then customize the SKILL.md file with required name and description frontmatter, and populate modular scripts/, references/, and assets/ directories with reusable resources.

The required SKILL.md frontmatter includes a name and description field, where the description must be written in the third person to ensure consistent skill discovery and predictable parsing across different projects.

Organize scripts, references, and assets into separate optional root directories within the skill bundle to maintain a modular layout, ensuring predictable resource resolution and easier maintenance across standardized skill structures.

Yes, pyyaml is listed as a required dependency, meaning you need it installed in your environment to support the validation tooling and frontmatter parsing used during skill creation and maintenance workflows.

You can update existing skills as well as design new ones, because the tooling enforces standardized frontmatter, body structure, and modular resource layouts to maintain consistency across both creation and maintenance tasks.

The best way to add example resources is to place them directly into the bundled scripts/, references/, and assets/ directories after running the Skill Initializer, leveraging the provided best-practice patterns and templates.
