my initial google on this topic wasn't very fruitful...
are there any harnesses that let switch between Claude and Codex when you have the 20/month plans 'seamlessly'. rough edges are fine but I'd like to maintain memories between harnesses.
Any conversation
A thing I've been doing lately is trying to come to the same conclusions others have without looking their the direct techniques and code. Last night I tried to figure out why people do vector based retrieval for RAG and ended up running these experiments: n0tls.com/โฆ/2026-09-03-i-think-โฆrag-with-grep.html
I'm still going to do an explore agent.
