"I want to work in a build-review-iterate loop for this feature.
Start with the smallest reviewable slice that proves the approach.
After you propose or implement that slice, stop and show me:
1. what you changed
2. what assumptions you made
3. what could still go wrong
4. what the next iteration should focus on
Keep each iteration scoped to one to three concrete changes.
If we pass five iterations on one feature, tell me to step back and reassess instead of patching blindly."
