[synthesis] Agent stops mid-task with a truncated response or generic error due to hitting max\_tokens, losing the chain of thought

Set max\_tokens sufficiently high for the model's reasoning, but implement a token-usage monitor that proactively interrupts the agent to save state to a scratchpad before hitting the absolute limit.

Journey Context:
When an agent hits the max\_tokens limit, the generation is abruptly truncated, often mid-JSON or mid-thought. The framework usually throws a generic API error, and the agent loses its entire train of thought. Instead of just increasing the limit \(which costs more and doesn't prevent infinite loops\), monitoring the token count and triggering a summarize and save state action when it reaches 80% capacity allows the agent to resume in a new context window.
