# Workflows Integration

Use Agents for interactive communication and state management. Add a Workflow when a task needs durable multi-step execution, independent retries, or waits for external approval. Choose based on recovery needs; consult [Run Workflows](https://developers.cloudflare.com/agents/runtime/execution/run-workflows/index.md) before implementing the integration.

## Design checks

Keep external side effects within durable steps, make retried operations idempotent, and persist the values needed after recovery through step results. Use the [Rules of Workflows](https://developers.cloudflare.com/workflows/build/rules-of-workflows/index.md) to choose step boundaries.

Progress reports and client broadcasts may repeat on retry. Use the documented durable step helpers for persistent Agent state changes and completion reporting; see [bidirectional communication](https://developers.cloudflare.com/agents/runtime/execution/run-workflows/index.md#bidirectional-communication).
