Best thing I've read on hacker news in so long. I relate so hard. Simon Willison's stuff on cognitive debt and "your job is to ship code you have proven to work" have led me to work on a project about Intent-Driven Development, because prior intent always seemed to dim with each set of changes. Might put it together into a real protocol and post here on hacker news sometime.
I'm wondering if we're working on the same thing. If you haven't seen my posts I suggest to look through them.
In short:
1. stacked-commits automation (cannot skip writing context/why/verify sections)
2. product specs (full ERD: https://excalidraw.com/#json=WT-oRUdyKBhAsDZJ3NwAR,WAbVgfO39...)
3. linking specs to code via SCIP indexes, and commits to ACs, later you can attach anything you want
