Working with coding agents changes the shape of the day: you can drive several fronts in parallel, and code shows up faster than it used to. Implementing is no longer the bottleneck.
The bottleneck became review, testing and shared knowledge. Code nobody understands is debt, even when it passes the tests. The limit on how much to generate is how much the team can review with quality.
A simple rule: generate freely, but only merge what you can explain and cover with tests. Speed without understanding turns into rework with interest.
