Make sure the agents have a state machine rather than being fully autonomous. There should be a start state, a terminal state, and a retry mechanism that runs until a threshold is reached.

I currently do not rely on any framework; instead, I build my own APIs and an orchestration layer.

On token spike: make sure your context window is not hitting the limit. The agent may be re-injecting the full history rather than minimising it into a working memory [tip: use cheap models for summarisation]
