I'm starting to get into a better groove with GPT-5.3-Codex for overnight builds. This is the key sentence that's working for me right now: "define a strict build contract (deliverables, tests, reports, and stop conditions) so it’s clearly an overnight-sized feature before coding" I then review this, make any tweaks and adjustments, have it run again, and don't stop until I feel like it actually has something that will actually take the whole night to code.
