How quickly do you also hit compaction when running? Also, if you open a new CC instance and run /context, what does it show for tools/memories/skills %age? And that's before we look at what you're actually doing. CC will add context to each prompt it thinks is necessary. So if you've got a few number of large files, (vs a large number of smaller files), at some level that'll contribute to the problem as well.

Quota's basically a count of tokens, so if a new CC session starts with that relatively full, that could explain what's going on. Also, what language is this project in? If it's something noisy that uses up many tokens fast, even if you're using agents to preserve the context window in the main CC, those tokens still count against your quota so you'd still be hitting it awkwardly fast.
