• Local Tool Execution - Executes functions on the client device in response to agent requests to access local hardware or private data.
• Model Response Streaming - Delivers model output through start, content, and end events for real-time user visibility.
• Agent Response Streams - Streams AI agent responses and reasoning telemetry incrementally for real-time client visibility.
• Agent Event Schemas - Establishes common event structures for text messages and tool calls to ensure consistent interactions.
• Client-Side Tool Execution Bridges - Synchronizes application state and executes local client-side tools in response to remote agent requests.
• Bi-Directional State Synchronizations - Maintains consistent application state between the backend agent and frontend UI through a continuous event stream.
• SSE-Based - Uses Server-Sent Events to stream real-time model responses and agent telemetry from server to client.
• Real-time Event Streams - Implements bidirectional event streaming between backends and frontends for exchanging messages and state.
• Server-Sent Events - Uses Server-Sent Events to deliver real-time streaming updates and incremental model responses.
