skill-creator

To create modular Claude skills, use a scaffolding framework that provides templates for skill creation, validation, and packaging. Initialize a new skill directory with a structured SKILL.md containing YAML frontmatter, then bundle optional scripts and references for deployment.

A SKILL.md file requires YAML frontmatter with name and description fields. The body contains the skill logic, and you can optionally include bundled resources like scripts, references, and assets to support modular design and domain-specific functionality.

Yes, pyyaml is a required dependency for this skill creation workflow. It is used by the validation and packaging scripts to parse the YAML frontmatter in SKILL.md files and ensure your skill metadata is correctly formatted.

Yes, the framework supports updating existing skills by guiding you through validation and packaging processes. It ensures existing SKILL.md files meet structural requirements and helps bundle new scripts or references into your current skill directory.

The best way to validate skill formatting is to run the built-in validation scripts against your skill directory. This checks your SKILL.md YAML frontmatter, verifies modular design components, and ensures all bundled resources are correctly structured for packaging.

Limitations include the strict requirement for valid YAML frontmatter in SKILL.md and reliance on specific packaging scripts. Complex asset structures may require manual validation to ensure all bundled scripts and references are correctly recognized by the framework.
