Report #63990

[architecture] Retrying or looping an agent pipeline causes duplicate side effects

Assign a globally unique idempotency key at the start of the multi-agent workflow and pass it through the context. Downstream tools and agents must check this key against a state store before executing write operations.

Journey Context:
Multi-agent workflows often involve retries \(e.g., an agent times out but the tool executed\). If an agent successfully called an external API but failed to return the result, a retry duplicates the action. Idempotency keys are standard in distributed systems but often forgotten in LLM orchestration layers, leading to duplicate emails or database records.
