This guide covers common patterns for integrating Dome Guardrails into your agent, including sync/async usage, error handling, and production best practices. You will learn how to perform: * **Basic integration pattern**: a standard pattern that wraps your agent with input and output Guards. * **Async integration pattern**: async/await pattern for async applications. * **Work with scan results**: how to interpret and use scan results. * **Use separate Guardrails**: how to use input and output Guardrails separately. * **Custom block messages**: how to override default block messages. * **Error handling**: how to handle Guard failures gracefully. * **Streaming responses**: how to handle streaming responses and Guard the complete response. * **Multi-turn conversations**: how to handle multi-turn conversations. * **RAG applications**: how to handle RAG applications (Guard both retrieval context and responses). * **Tool-using agents**: how to handle tool-using agents (Guard both tool inputs and outputs). The programmatic protection capabilities and Dome integrations are currently in private preview and subject to change. ## Next Steps Detailed Guard configuration Build custom detection methods OpenTelemetry integration
