skill-creator

Run init_skill.py with a skill name and output path to scaffold a directory containing a templated SKILL.md. Optionally pass --resources scripts,references,assets and --examples to pre-create resource folders with placeholder files.

Run quick_validate.py against the skill directory. It checks that frontmatter exists, parses as YAML, contains name and description, uses hyphen-case names under 64 characters, and includes only allowed keys.

The validator permits name, description, homepage, license, allowed-tools, user-invocable, and metadata. Name and description are mandatory; descriptions must be non-empty, under 1024 characters, and contain no angle brackets.

Yes, it falls back to a minimal built-in parser that handles simple key-value frontmatter and indented multiline values. Complex YAML syntax beyond that requires installing PyYAML.

Run package_skill.py with the skill folder path and an optional output directory. It validates the skill first, then writes a zip-based .skill archive with deterministic entry ordering while skipping symlinks and excluded directories.

The packager skips symlinks, version-control directories like .git, __pycache__, and node_modules for security and reproducibility. It also rejects any file whose resolved path escapes the skill root.
