What it does

Walks through configuration, hooks, MCP wiring and custom slash commands in versioned layers rather than as a flat reference, so you can go one level deeper at a time. Community-written rather than an Anthropic publication, and the tool it describes moves quickly, so check anything version-sensitive against current docs. The opening sections double as promotion for the author's related packages and starter kit. MIT.

Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
