Report #55120

[architecture] Orchestrator retries a failed multi-agent workflow step, causing duplicate side-effects like double charges or emails

Assign a deterministic idempotency key \(e.g., workflow\_id \+ step\_id\) to every state-mutating agent action, and require tool-execution endpoints to reject duplicate keys.

Journey Context:
LLMs are stateless and non-deterministic. Orchestrators \(like LangGraph, Temporal\) handle retries automatically to overcome transient API failures. If an agent calls a tool that mutates state, and the orchestrator times out waiting for the response, it will retry. Without idempotency keys, any transient timeout leads to duplicated real-world actions.
