Event system with 16 standard AG-UI event types + - `stream.nim`: Event stream utilities and operators + - `observable.nim`: RxJS-inspired Observable implementation for async event streams + -

`http_agent.nim`: HTTP-based agent implementation + - `verify.nim`: Event verification logic + - `apply.nim`: Event application to agent state + - `transform/`: SSE and chunk event transformations + -

`proto.nim`: Protocol Buffer encoding support + +### Key Patterns + +- **Event Pipeline**: All agent interactions are modeled as events flowing through a pipeline +- **Abstract Agent**: Agents extend `AbstractAgent` and implement the `run` method returning an event stream +- **State Management**: Agents maintain conversation state with messages and thread context +- **Dual Encoding**: Supports both JSON/SSE and Protocol Buffer formats +- **Async-First**: All I/O operations use Nim's `Future[T]` and async/await + +### Development Notes + +- When adding new event types, update both `events.nim` and corresponding validation logic +- Test files mirror source structure - add tests for any new functionality +- Use `Option[T]` for nullable fields in type definitions +- Event streams should handle errors gracefully and propagate them as error events +- HTTP agents should respect content negotiation headers for format selection \ No newline at end of file diff --git

The AG-UI Nim SDK implements a simplified Protocol Buffer encoder and decoder that supports all standard AG-UI event types. + +## Implementation Details + +### 1.

Architecture + +The Protocol Buffer implementation is organized into three main components: + +1. **Encoder Core** (`encoder/proto.nim`): + - Handles serialization of AG-UI events to Protocol Buffer binary format + - Implements wire format encoding and decoding + - Provides fallback mechanisms for unknown event types + +2. **Stream Transformation** (`client/transform/proto.nim`): + - Parses Protocol Buffer streams into event sequences + - Handles fragmented messages and length prefixes + - Integrates with the Observable pattern for event streaming + +3. **Media Type Integration** (`encoder.nim`): + - Manages content type negotiation + - Selects the appropriate encoder based on client preferences + +## Usage + +To use Protocol Buffer encoding in requests: + +```nim +# When creating an HTTP agent, specify proto support +let agent = newHttpAgent( + baseUrl = "https://api.example.com", + mediaType = AGUI_PROTO_MEDIA_TYPE # Use Protocol Buffer format +) + +# The client will automatically encode events using Protocol Buffers +await agent.sendTextMessage("Hello, world!") +``` + +When receiving Protocol Buffer events: + +```nim +# Create a stream and subscribe to events +let events = agent.streamEvents() +events.subscribe(proc(event: BaseEvent) = + # Events are automatically decoded from Protocol Buffers + echo "Received event: ", event.type +) +``` + +## Benefits and Limitations + +**Benefits:** +- Reduced bandwidth usage (typically 30-50% smaller than JSON) +- More efficient parsing for large event sequences +- Type-safe serialization with explicit field mapping + +**Limitations:** +- Current implementation is simplified and may not handle all edge cases +- Performance optimizations are still needed for very large payloads +- Limited test coverage compared to other components + +## Future Enhancements + +1.
