FAQPage Schema
How do I create and package a new Claude skill?

To create a Claude skill, run the initialization script to scaffold the folder structure, then customize modular resources like scripts and references before validating and packaging the unit.

What is the required folder structure for skill creation?

Skill creation requires a specific folder structure with YAML frontmatter to ensure safe and repeatable development, alongside optional modular resources like scripts, references, and assets.

How do I validate and iterate on Claude skills during development?

You validate and iterate on Claude skills by applying clear validation criteria to check YAML frontmatter and folder structure, then following iterative improvement workflows to ensure quality.

What's the best way to structure modular resources in a skill?

The best way to structure modular resources is to separate scripts, references, and assets into distinct components within the skill folder, following packaging guidelines for safe maintenance.

Do I need YAML frontmatter to build a reliable Claude skill?

Yes, YAML frontmatter is required when building a Claude skill to enforce standardization, reduce ambiguity, and ensure safe, repeatable skill development and maintenance workflows.

Why does my Claude skill fail validation during packaging?

Skill validation fails during packaging when the folder structure or YAML frontmatter does not meet the enforced requirements, preventing safe and repeatable skill development.
