Report #53445

[synthesis] Agent repeatedly calls an idempotent API in a loop, assuming it is safe, but triggers rate limits or side-effect cascades in downstream systems

Track tool call frequency and implement exponential backoff or hard limits on repeated calls to the same endpoint, even for idempotent operations.

Journey Context:
Agents are often taught that idempotent methods \(like HTTP PUT\) are 'safe' to retry. However, while the direct state change is idempotent, the downstream effects \(logging, triggering webhooks, rate limiting\) are not. An agent stuck in a retry loop can DDOS a service or flood an audit log. Treating idempotency as a license for unlimited retries is a fallacy; rate limiting and backoff must be enforced at the orchestration layer.
