# Task: Extend HttpResult with Streaming Fields ## Context Extend the existing `HttpResult` dataclass to include streaming-specific fields. This allows callers to know if streaming occurred and how many events were processed. ## Dependencies - Must complete: `01-add-stream-config-dataclass.md`, `02-add-stream-destination-dataclass.md` ## Files to Modify - `kiwi_mcp/primitives/http_client.py` ## Implementation Steps 1. Find the existing `HttpResult` dataclass 2. Add optional streaming fields: `stream_events_count`, `stream_destinations` 3. Ensure fields are optional (default to None) to maintain backward compatibility ## Code Snippet From doc lines 298-311: ```python @dataclass class HttpResult: """Extended with streaming support.""" success: bool status_code: int body: Any # Can be buffered events if stream mode headers: Dict[str, str] duration_ms: int error: Optional[str] = None # New streaming fields stream_events_count: Optional[int] = None stream_destinations: Optional[List[str]] = None ``` ## Success Criteria - [ ] `HttpResult` includes new streaming fields - [ ] Fields are optional (backward compatible) - [ ] Type hints are correct - [ ] Existing code still compiles ## Verification Command ```bash python -m py_compile kiwi_mcp/primitives/http_client.py # Run existing http_client tests to ensure no regressions pytest tests/primitives/test_http_client.py -v ``` ## Notes - `stream_events_count` tracks how many SSE events were processed - `stream_destinations` lists which sink types were used (for debugging) - These fields are None for non-streaming requests (backward compatible)
