I’m doing enterprise coding tasks that used to take a month of whole team coordination from mockups to through development and testing in 3 days now. It’s all test driven development, codex 5.3 and a small team of two people who know how to hold it right orchestrating the agents. There’s no reason not to work this way. The sociotechnical engineering aspects of this change are fascinating and rewarding to solve.

I work for an old enterprise, so far rather conservative with LLM/AI usage. However the copilot cli adoption in the last 2 weeks is spreading light wild fire. Codex 5.3, a good instructions file and it works. Features are getting done and delivered in days, proper test coverage is done, proper documentation in place. Onboarding to it is also very fast.
Can you give an example of such features?
Porting tons of untyped js legacy front end code to vue with typescript and figma designs. Highly configurable business to business app (i.e lots of permutations). Everyone seems to have a “system”. I recommend looking at the OpenAI Cookbook for long running plans and do TDD to the extreme. https://developers.openai.com/cookbook/articles/codex_exec_p...
What's the feature that was built though? This sounds like low-value refactoring. They are fundamentally different development workflows.
Yes porting and also implementation of new features. Typical client requests for new functionality in business to business software.
Surely the point of doing mockups is to get feedback.

Are you just not doing that anymore?
