What it does
Six months of daily practice written up as a structured guide: when to reach for agents versus skills versus commands, how the tool actually works underneath, security posture, and how to design your own workflows rather than copy someone's config. Separate entry points for developers, tech leads, CTOs and product managers, plus quizzes, templates and offline PDF/EPUB builds. Community-written rather than an Anthropic publication, so treat fast-moving details as dated; CC BY-SA 4.0.
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.
