The robust approach is to have the called system return a unique identifier (such as a message ID, order number, or record primary key) after successful execution, and to check that the identifier was indeed generated by this call and can be queried in the target system.

VerifiedA common technique for achieving idempotency is for the client to generate a unique idempotency key sent with the request, while the server records the result associated with that key and returns the cached result upon receiving a duplicate request.73% similarUnverifiedEach line of a bookkeeping user message restates something the program can read from its own records, for example the task list knows what is done, the test runner knows what failed, and the workflow knows what the next step is.73% similarUnverifiedIn the solution, the agent confirms with the user before executing any write operations.71% similarUnverifiedDesign an idempotency key for each automated action (such as ticket ID + operation type), so that the system checks whether the operation has already been completed before retrying, which can avoid duplicate tickets, duplicate charges, or duplicate emails when retries are triggered by network jitter or API rate limiting.71% similarUnverifiedAdd a response validator: if a request declares tools but the response contains no tool call, the router automatically retries at one tier higher.70% similar
