J. Cook Claude Code Mastery - 60 Tools You're Not Using

You use Claude Code every day. It has 60 tools. You've found maybe 6. Developers reverse-engineered what ships inside it and proved it. An 11-layer planning system. Background agents and a planning pipeline most tutorials still skip. Meanwhile, developers on reddit are posting setups where Claude Code writes production code on the first try, remembers their entire architecture, and improves itself between sessions. The difference isn't skill. It's knowing what's actually inside the tool. This 2nd edition release gives you the complete internal architecture the getting-started tutorials skip. You'll map all 60+ tools by the end of Chapter 2. You'll build a .claude/ configuration that makes Claude Code follow YOUR coding style, YOUR project rules, and YOUR conventions by Chapter 3. By Day 14, you'll run multi-agent pipelines where 3 subagents research, code, and test in parallel, connected to your tools through MCP. By Day 30, you'll have the setup that turns a $20/month subscription into $150/hr client work. This is what Claude Code can't teach you about itself. You can't ask it how its own planning system decides what to do next. You can't ask it which of its 60 tools it's choosing and why. You can't ask it how to stop it from nuking 2.5 years of production data. This book covers the architecture, the safety rails, and the workflows that separate developers who use Claude Code from developers who master it. What you'll walk away with: 1. A map of all 60+ internal tools and when each one activates. 2. A .claude/ configuration that makes Claude Code remember your entire stack. 3. Multi-agent pipelines where subagents handle research, coding, and testing through MCP. 4. Permission boundaries that prevent the production disasters everyone fears. 5. A client-ready workflow worth $150/hr to companies that need Claude Code setup. 6. Team-wide standards that stop AI slop from merging into your codebase. 7. A 30-day roadmap from "I use Claude Code" to "I run Claude Code". Every week, 50 more "Claude Code for Beginners" books hit the Kindle Store. None of them cover the internal architecture, the 11-layer planning system, or how to build multi-agent pipelines that actually ship. This is 200+ pages of what the teardown revealed and what you can build with it. Scroll up and grab your copy.
