[synthesis] Agent hits max iteration limits and returns partial, low-quality results instead of failing

Track the Levenshtein distance or semantic similarity between consecutive tool calls or agent thoughts. If the similarity exceeds a threshold \(e.g., 0.9\), trigger a circuit breaker and force the agent to switch strategies or escalate, rather than letting it hit the max iteration limit.

Journey Context:
Agents often get stuck in subtle loops: read file, attempt edit, fail validation, read file again. Because the state changes slightly each time, it is not a hard loop. It eventually hits the max\_iteration limit and returns whatever it has, often with a generic message. Monitoring just sees completed in 25 steps. The leading indicator is the similarity of consecutive actions. High similarity means the agent is stuck in a local minimum, degrading the final output quality long before the hard limit.
