I’ve had good, alternative experience with my sideproject (adashape.com) where most of the codebase is now written by Claude / Codex.

The codebase itself is architected and documented to be LLM friendly and claude.md gives very strong harnesses how to do things.

As architect Claude is abysmal, but when you give it an existing software pattern it merely needs to extend, it’s so good it still gives me probably something like 5x feature velocity boost.

Plus when doing large refactorings, it forgets much fever things than me.

Inventing new architecture is as hard as ever and it’s not great help there - unless you can point it to some well documented pattern and tell it ”do it like that please”.
