Report #8075

[architecture] Multiple agents attempt to use the same non-idempotent external tool \(e.g., sending an email, deploying code\) simultaneously

Assign exclusive tool execution rights to a single 'Executor' agent or implement a distributed lock with a TTL before invoking non-idempotent APIs.

Journey Context:
If Agent A and Agent B both decide the code is ready and independently trigger a deployment pipeline, you get duplicate deployments or conflicting releases. Agents lack inherent awareness of each other's side-effects. Simply adding tools to multiple agents creates a race condition. By centralizing side-effect execution to a dedicated agent, or strictly locking the resource/tool, you ensure exactly-once execution. The tradeoff is a slight bottleneck at the executor, but safety is paramount for stateful external actions.
