To package procedural guidance, you write a SKILL.md file with valid frontmatter, add only the necessary scripts, references, and assets, then validate and package the finished directory into a distributable .skill file.

Structuring metadata for workflow automation skills requires a precise SKILL.md frontmatter definition, which separates core instructions from bundled scripts and references to ensure deterministic execution and proper validation.

Yes, pyyaml is a required dependency to build and validate skill packages, as it is necessary for parsing the SKILL.md frontmatter and processing the metadata required for packaging.

You can update existing skills by modifying the SKILL.md instructions and adding new bundled resources like scripts or references, then running validation before repackaging the updated directory.

Core procedural guidance and metadata belong in SKILL.md, while executable logic, supporting documentation, and static files should be separated into bundled scripts, references, and assets to support deterministic execution.

Skill validation typically fails due to missing or incorrectly formatted SKILL.md frontmatter, or due to missing required dependencies like pyyaml, which prevents the packaging process from executing deterministically.
