# Agent Best Practices

> Guardrails and patterns that keep agent calls safe and reliable.

* Use <code>Idempotency-Key</code> on card creation and other idempotent writes.
* Use propose -> execute for sensitive actions.
* Return small, structured results with a <code>summary</code> for LLM chaining.
* Prefer cursor pagination and search + get-by-id pairs.
* Implement bounded retries on networking timeouts.
