Shift verification focus from prompts to harnesses

Summary

Teams that verify five approaches in parallel via automated gates outpace those waiting for human code review. Your job shifts from diff approval to harness design—the only role that compounds.

1. 1.A team that can generate five approaches and verify all five in an afternoon will outpace a team that generates one and waits a week for feedback. The game is not "how fast can we build" any more. It is "how fast can we tell whether this is right".
2. 2.Build better review surfaces, not better prompts. Make feedback unnecessary where you can by having the agent verify against a realistic environment before it asks a human, and make feedback instant where you cannot.
3. 3.AI models do not "understand" code the way humans do. They infer meaning from patterns in tokens and depend heavily on what is explicitly expressed in the code.
4. 4.LLMs are great for exploratory and fuzzy rules, but once you have something that really is objective, converting it to a formal, unambiguous, deterministic format can give you more assurance
