Agent actions need idempotency keys to survive retries and duplicate calls

- The post argues that agent retries, flaky networks, and duplicate tool calls make idempotency mandatory.
- It recommends generating an idempotency key for every side-effecting action, storing the key and result before execution, and returning the stored result on retry.
- The framework also suggests using a 24–72 hour TTL, embedding agent/task/action identifiers in the key, and logging conflicts for later analysis.
