[synthesis] Agent permanently degrades to lower-quality fallback tools after transient errors

Implement circuit breakers with automatic recovery \(half-open state\) for primary tools, and explicitly track which tool variant resolved the task in your metrics to detect silent downgrading.

Journey Context:
Agents often have fallback mechanisms \(e.g., if GPT-4 fails, use GPT-3.5; if the precise search API fails, use a broad web search\). If the primary tool experiences a transient spike in 500s, the agent falls back. However, if the agent's routing logic caches the failure state or the orchestrator isn't notified of the recovery, the agent continues using the lower-quality fallback. Tasks still complete, so success rates look fine, but precision and depth are permanently degraded. Teams only realize months later when auditing why outputs lack nuance.
