>the best ideas float up to Codex/Claude imo

They only float up if people create things like RTK and other people try them though.

It's fair to sit this one out and let others figure out if it's worth it or not but tools like RTK, Headroom, caveman mode and others do reduce input and output tokens that need to be processed, and for local LLMs that can have measurable speedups. Whether or not that ultimately hurts the resulting output I don't have enough data to say, but I am happy to play with them to find out.
