No matter how good compaction is, on some big projects it needs to read a lot of files. In my experience the first 200.000 tokens go FAST, but after that it slows down. Most of my Fable sessions don't go over 500.000 tokens, I don't need to compact once. But when I use Codex a single session has to compact over and over again.

In my experience the only reason it needs to read a lot of files is if your agents.md is deficient. It should only need to read the file it's actually working on, maybe a few others. Everything else should be explained in documentation
