Mastering GPT-5 Codex Development: Build Production-Ready Software Projects with AI-Assisted Engineering, Intelligent Coding Workflows, Testing, Deplo

By Erynd Blackthorn

Your AI coding agent isn't the problem. Your process is.
Codex will happily build you a fully-featured, beautifully tested, completely wrong product because nothing told it to stop. Mastering GPT-5 Codex Development is the field guide for engineers who want a coding agent doing real, trusted work on a production codebase, not just isolated tasks.
Built around one real system, Meridian, a sprint tracker with a first-class API and Slack bot - this book takes you from a blank repository to a production system a team actually depends on, chapter by chapter: Scope a project so Codex stops guessing and starts buildingTurn a rough idea into a requirements document an agent can followDesign a modular architecture that survives fresh Codex sessions with no memory of yesterdayBuild, test, debug, and ship features with an agent doing an increasing share of the workHarden for security, production readiness, deployment, and long-term scaleEvery technique here has been used on a real project, watched fail in a specific way, and fixed. If you already know how to build software and want to build it well alongside a coding agent, not a first programming book, not a prompt-engineering trick list, this is it.
