[synthesis] Agent exhausts the context window by repeatedly retrying a failing tool call with identical or minimally altered parameters

Implement a 'circuit breaker' that detects repeated identical tool calls and forces the agent to switch strategies or request human intervention, rather than allowing continuous retries.

Journey Context:
When a tool call fails \(e.g., due to a transient API error or a logical error in the parameters\), the agent often interprets this as 'try harder.' It will call the exact same function with the exact same arguments, filling the context with identical error messages. This pushes the original goal out of the context window, leading to an eventual context limit crash. Rate limiting alone doesn't fix this; the agent needs an explicit injected message: 'You have failed N times with the same approach. Stop using \[Tool\] and try \[Alternative Tool\] or ask for help.'
