I know a lot of people like to say that compaction makes this moot, but the level of detail you lose across compaction is wildly too much for most things that I do, unfortunately. Perhaps if your plans don't have as much detail, or if you're not, for example, having a discussion with a lot of nitty-gritty then it's fine? The lack of long context is the main reason that I still end up using Anthropic. The worst is whe…

I agree. Compaction sucks, so I made tools that let the LLM selectively delete (and recall if needed) chunks of its context. You might want to try context bonsai if you're routinely hitting the auto-compaction wall.

The other day I was trying to find out exactly how much context size 5.6 has in codex CLI (via subscription) and I didn’t find that documented in any of the obvious places. Sort of ridiculous that we have to find this out in X or Reddit, e.g: https://www.reddit.com/r/codex/s/hVv29obfFD

it's in the GitHub repo

I've implemented a similar approach – although I'm surprised not to see mention of cache prefix busting in there!

What plan are you on?

With Anthropic I run out of quota very fast on a Pro plan with long contexts.

Is long context primarily for Max tier or for API usage? Or are there special ways of working with long context on a Pro plan?

That seems quite different from my design process. I write a plan.md that goes through multiple revisions. The plan is the memory. Restarting and reading the plan again to do another review is a good way to get a different perspective.

I have a hunch that OpenAIs proprietary compaction endpoint actually does something similar on the backend.

The best way around this for me is planning a project well ahead of time and using subagents to execute individual tasks while the primary agent acts as a PM.

I haven’t found I need to plan way too far ahead of time as long as I’ve defined the interface between the tasks
