Agentic Coding Workflows with Codex: Build Complex Workflows with ChatGPT Codex AI Agents and Deploy in Days

Something fundamental has changed about how software gets built, and it is not about new programming languages or faster hardware. Autonomous agents can now navigate a codebase, write tests, execute terminal commands, create branches, and produce pull requests—not just suggest the next line of code.

Agentic Coding Workflows with Codex shows you how to build complex workflows with ChatGPT Codex AI agents and deploy in days instead of weeks. This audiobook treats agentic development as a genuine paradigm shift in how engineering work gets delegated, not a faster version of the same old process.

Inside this book you will learn the agent-native development paradigm and what fundamentally separates it from assisted coding, how Codex actually works under the hood so you can use it deliberately, the async delegation shift and what it means to hand off real engineering work and walk away, how to set yourself up for agentic success from the very first project, the AGENTS.md blueprint that gives every project persistent context an agent can rely on, prompt engineering specifically for agentic tasks rather than conversational prompting, the five core agentic workflows that cover the large majority of real development work, test-driven agent development that builds quality into the process itself, git and pull request workflows that integrate agents cleanly into how teams already ship code, multi-agent architecture patterns for tasks too large for a single agent, skill engineering and agent customization for your specific codebase and standards, how to integrate Codex into existing toolchains without disrupting what already works, how to build and ship genuinely complex products using agentic workflows, how to scale from a solo workflow to a full team workflow, and safety, governance, and responsible delegation as agents take on more consequential work.
