The cost of coming back to a piece of code has plummeted

We used to put a lot of effort into even the smallest code change. Coming back to it afterwards was expensive. Coding is no longer the limiting factor, human time is.

Code reviews are where this plays out every day. They make sure the solution is sound, shared amongst the team, and actually solves the problem. For large features, this absolutely needs to happen.

But what about that PR to fix an issue in Safari? A two-line query change? The human time spent nitpicking those could go towards the hard problems. Put an agent harness in place, a code reviewer with custom instructions, hooks to enforce linting and tests, and let the team focus on the problems that actually need them.
