A metaskill for writing other skills according to the agentskills.io spec. It walks you through the five-step authoring process: validating metadata with a Python script, setting up the directory structure with scripts/references/assets folders, drafting the main SKILL.md in third-person imperative voice, bundling fragile logic into CLI tools, and doing a final review for hallucination gaps. The progressive disclosure enforcement is the standout bit, it keeps core logic under 500 lines by commanding agents to read reference files only when needed. Useful if you're publishing skills to a marketplace or building an internal library with consistent structure, less so if you're just winging it with one-off prompts.
