Defaults matter and keepToolMessages = false in AgentProcessor right now, this causes the LLM to forget what tool calls it made before and their results during subsequent requests.

Keeping tool messages and results is important since it enables the LLM to be fully aware of the things it has tried and potentially failed at in later messages.

Of course the downside is increase in context size, but shrinking the message bag (context) should be done by a separate service.
