What issue are you seeing?

When an agent calls a tool and is right at the edge of the compaction threshold, the agent gets stuck.

What steps can reproduce the bug?

1. Agent calls a tool with very small context window left
2. Agent gets stuck. No compaction is called nor does the agent continue.

What is the expected behavior?

1. Agent calls a tool with ver small context left
2. Context gets compacted
3. Agent resumes

Additional information

My hunch is that it's due to the tool call output going over the compaction threshold. And there being a race.

Every time I manually force-steered the agent afterwards, it immediately did a context compaction and resumed correctly after that.
