[synthesis] Agent retry loops corrupt state by repeating non-idempotent tool calls

Wrap all non-idempotent tool calls \(e.g., database inserts, API POSTs\) in a transactional guard or idempotency key mechanism, and design tool schemas to explicitly flag idempotency requirements.

Journey Context:
When an agent encounters a timeout or rate limit, its default behavior is to retry the exact same action. If the original call succeeded on the server but failed to return, the retry duplicates the action \(e.g., duplicate DB rows\). The synthesis is that standard LLM error-handling logic \(retry on failure\) directly conflicts with distributed systems principles \(exactly-once delivery\). Agents need to know which tools are safe to retry and which require idempotency keys, a cross-domain insight bridging LLM prompting and distributed systems.
