What it does

A large library of reusable skill packages for Claude Code and a dozen other coding agents, reaching well beyond development into DevOps, marketing, security hooks, compliance, C-level advisory personas, productivity routines and an academic research stack. Breadth is the draw and also the hazard: install selectively, because everything you add competes for context and budget, and a skill labelled CFO or general counsel produces text, not professional advice. 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.
