To create and package Claude skills, use a template-driven approach that scaffolds a lean SKILL.md with required frontmatter and optional resource directories. You initialize the structure, customize the body, then validate and package the skill directory using provided scripts.

A Claude skill requires a SKILL.md file with standardized frontmatter for discovery and activation, accompanied by optional bundled resources organized into scripts, references, and assets directories to ensure consistent packaging.

Skill packaging and validation workflows require the pyyaml dependency to parse and enforce frontmatter quality. You need this Python library installed in your environment before running the initialization and validation scripts.

The best way to validate a Claude skill is running the quick_validate.py script against your skill directory. This enforces frontmatter quality and checks the lean SKILL.md body structure to ensure consistent packaging before deployment.

Claude skill validation fails when frontmatter quality is missing or the SKILL.md body is not lean. The packaging process enforces strict frontmatter standards and structural validation, so missing required metadata fields will cause the script to reject the skill.
