skill-creator

Run init_skill.py with a kebab-case skill name and an output path. It generates a skill directory containing a SKILL.md template with TODO placeholders plus example scripts, references, and assets folders you can customize or delete.

Run package_skill.py with the path to your skill folder and an optional output directory. The script validates the skill first, then creates a zip archive with a .skill extension containing the full directory structure.

The frontmatter must include name and description fields. The name must be kebab-case, lowercase letters, digits, and hyphens only, with a 64 character maximum. The description cannot contain angle brackets and is limited to 1024 characters.

Validation fails when required fields are missing, the name uses invalid characters or consecutive hyphens, or unexpected keys appear beyond the allowed set of name, description, license, allowed-tools, metadata, and compatibility.

Use scripts for deterministic, repeatedly rewritten code like file conversions that can execute without loading into context. Use references for detailed documentation such as schemas or API guides that Claude reads only when needed.
