Yes, for coding, they aren't overthinking enough. I want much more thinking and less code in the PR! Even with the best frontier models, I still have to guide them towards the right solution. The more thinking they do, the less code they write.

I have quite a complex codebase where I made a lot of nuanced decisions with regards to keeping the processes embarrassingly parallel, DB indexing, caching, async/await, backpressure monitoring, spam prevention, schema validation, etc... and now the agents are really good at adding features on top and prompting is minimal.

If you have a relatively large codebase and never even once cut a corner, then the AI agents tend to follow through with that style and the ratio of reasoning-to-code increases. Worth it.
