Jissen Claude Code Nyumon (A Practical Introduction to Claude Code)
A Way of Thinking about AI Coding for Use in Real-World Development
Masahiro Nishimi, Shingo Yoshida, and Yuki Oshima
Summary
A Japanese-language book on spec-driven development with the AI coding agent Claude Code, by Masahiro Nishimi, Shingo Yoshida, and Yuki Oshima, the CEO, COO, and CTO of Generative Agents. It starts from the basic use of Claude Code and MCP, then works through the concrete steps of spec-driven development. The coding agent is described as a tool that streamlines and automates refining requirements, planning, executing tasks, and verifying results. The book points to the collapse of design that Vibe Coding brings about, and shows how to build agreement with the AI through documents such as CLAUDE.md. Claude Code is treated as an agent that carries out that agreement, with a flow in which the plan is presented and approved before implementation. The book also covers using features such as Async Subagents, review automation with Claude Code Action, and how Claude Code works.
Target Readers
- Software engineers who want to raise their development productivity, including those who spend their time fixing code written by AI and worry about the long-term consistency of the design
- Tech leads and managers who want to introduce AI tools to their teams and are looking for guidance on what to delegate and what to expect
- Product managers who want to understand a development process that uses AI, including the flow of spec-driven development

Kaihatsu Koritsu o Up Suru! Claude Code Jitsuyo Nyumon (A Practical Introduction to Claude Code for Boosting Development Efficiency)
Fumitaka Osawa
Reason: After getting hands-on with setup, basic operation, and features like MCP servers and skills in 'Claude Code Practical Guide,' the next step is to rethink how you use those features at all. 'Practical Claude Code Introduction' doesn't repeat operational steps—it addresses the spec-driven development mindset that pulls you out of vibe coding, and the CLAUDE.md-based practice of building agreement with the agent.

Reason: Once you've reframed Claude Code as an 'agent that executes agreements' and internalized the spec-driven development pattern, you naturally want to see with your own hands what happens inside such an agent. Building AI Agents pushes you from being a user to a builder by having you implement the reasoning loop and tool calls in TypeScript yourself.
