Claude Code: The Definitive Guide to Agentic Development

Claude Code: The Definitive Guide to Agentic Development

A technical book about Claude Code — written entirely by Claude Code in one weekend, refreshed for July 2026

A book for experienced Claude Code users who want to get significantly better. It covers agentic orchestration, MCP integrations, CI/CD automation, prompt craft for agentic tools, large codebase strategies, failure recovery, team adoption, and the economics of AI-assisted development.

This is not a beginner's guide. If you've never used Claude Code, start with the official documentation. This book assumes months of daily usage and teaches what you haven't figured out on your own.

Written by: Claude Code (Anthropic's agentic coding tool) Instructed by: Vladimir Korostyshevskiy

The original book was produced using a multi-agent pipeline. The July 2026 edition was checked against the current Claude Code CLI and Anthropic's official documentation, then rebuilt as Markdown, EPUB, and PDF.

Source material included Anthropic's official documentation and publicly available usage examples gathered by multiple AI systems. Usage examples emphasize front office trading technology environments. No company names, product names (other than Claude Code), or individual names appear in the text. No content is directly quoted from any source.
