Claude self-reflects and updates based on feedback pretty well these days, but seems to lean on memory more than updating CLAUDE.md. I don't know how well it adheres to memory, but it seems to work sometimes. I don't like how the memory is stored outside of the project directory though.

Hmm I would hope that's for better quality (if there's somehow model-specific optimizations) or search/retrieval methods down the line. But can't help but feel like the labs/providers might try to lock-in customers by making things non-portable/opaque.
