[synthesis] Transient API errors cause successful but corrupted agent runs

Implement idempotency keys for all state-mutating tool calls \(e.g., file writes, PR creation\) and validate state existence before writing. Monitor for orphaned resources created during retry loops by tracking correlation IDs across the entire agent lifecycle, not just per-attempt.

Journey Context:
Agents often implement naive retry logic for API rate limits or transient failures. If a write tool call times out but succeeds on the server, the agent retries, creating duplicate state \(e.g., duplicate PR comments, double-applied patches\). The run eventually succeeds, masking the corruption. Standard observability sees a successful run with a few retries. Only by tracking idempotency and cross-referencing the final state with the intended state of the specific attempt can you catch this silent degradation.
