About the Book
Codex CLI is the most comprehensive guide to agentic software engineering with OpenAI's command-line coding agent. Across 32 chapters, you'll move from first principles to advanced orchestration patterns — covering prompting, AGENTS.md configuration, MCP servers, hooks, skills, sub-agents, worktrees, CI/CD integration, security hardening, and enterprise deployment.
Whether you're a solo developer looking to multiply your output or an engineering lead rolling out agentic workflows across a team, this book gives you the mental models and practical techniques to work effectively with AI coding agents.
Written by Daniel Vaughan, drawing on real-world experience and community insights, every chapter includes learning objectives, worked examples, and hands-on exercises.
About the Author
I help organisations understand and navigate the future of work, specifically how Agentic AI is fundamentally transforming software engineering.
With 25 years of experience across enterprise, startup, and academic settings, my focus is now entirely on the most profound technological shift I've seen: the transition to AI-native architectures. I am a technology leader and software architect who specialises in generative AI and cloud strategy, building scalable systems where human engineers and autonomous agents collaborate seamlessly.
I thrive on building the culture and environments needed to support this new era of engineering. My approach is entrepreneurial and customer-focused, with a strong bias for action. Whether I'm advising leaders on AI adoption or getting hands-on with Agentic workflows, my goal is to turn AI hype into tangible, proven success.
