OpenAI Codex Built an Entire Feature From One Prompt
A hands-on walkthrough of one real feature moving from the original prompt through codebase review, implementation, tests, and final review.
Show the complete task, not just the generated code.
Most AI coding demos stop when code appears. This video follows the harder and more useful part: how Codex understands an unfamiliar codebase, chooses an implementation, validates the change, and returns work that is ready for review.
Keep the original request, the important implementation decisions, and the test evidence visible. The result should feel practical and inspectable, with the developer making the final call before anything ships.
