Describe the bug

On latest eca version, autocompacting shows 0 / 200 context but then immediately baloons to 140k without any relevant reasons. In the screenshot below you see only a sub agent started that I stopped after 1 small step. This leads to unusable agents because they baloon context and have to compact 5 times in 5 minutes and having to restart the tasks they were doing

To Reproduce

Steps to reproduce the behavior:

1. Start a session
2. Give agent a relatively complex task
3. See context baloon
4. See autocompacting
5. Immediately after 1 step after compacting, context goes to 140k

Expected behavior

After compaction, the context should be 20-30k tokens max.

I cannot replicate it anymore but will update here if it continues to happen

Yeah that's pretty weird, I can't repro as well

[ericdallo]

I wonder if it's related with you stopping the prompt but it should not

[ovistoica]

No, I stopped after I saw the context fill up immediately after compacting. My impression at the time was that it was because of the subagent spawning
