[architecture] How do I make an agent chain resilient to duplicate or retried requests?

Assign every cross-agent work unit a deterministic idempotency key and make receivers idempotent: same key plus same inputs must produce the same effect, not a second effect. Store the resulting output keyed by that idempotency key so retries short-circuit instead of re-executing.

Journey Context:
Agents are expensive and flaky, so retries are inevitable. Without idempotency, a retry turns one email into ten, one database row into many, or one expensive LLM call into a budget drain. The idempotency key should be generated by the caller from the semantic inputs, not the receiver, so the same logical request maps to the same key across retries. This pattern is well understood in payment APIs but underused in agent systems. The tradeoff is storage and key design effort versus correctness under retry.
