feat: ecosystem architecture enhancements (Graph, Loop, Context, Harness)#34
Merged
Conversation
The README documented the retry config field as RetryableStatusCodes but the actual field in retry.go is RetryableStatuses.
Add StreamReader.NextContext(ctx) that closes the underlying response body on context cancellation, unblocking the scanner on stalled streams. The existing Next() method is unchanged for backward compatibility.
Add SystemPrompt, Temperature, and TopP fields to AgentConfig and ChatRequest, and wire them through buildRequest. These are sent with omitempty so they're backward-compatible with daemons that don't yet support them.
Add ToolChoice and ParallelToolCalls fields to ChatRequest, and wire ToolChoice through AgentConfig and buildRequest. Mirrors the OpenAPI tool-use spec (tool_choice, parallel_tool_calls) so callers can control tool selection behavior end-to-end.
…uest fields to OpenAPI spec The OpenAPI spec was missing system_prompt, temperature, top_p, tools, tool_results, tool_choice, and parallel_tool_calls from ChatRequest. Also adds the ToolResult schema that was referenced but not defined.
The TypeScript SDK now completes the SDK trio alongside hawk-sdk-go and hawk-sdk-python; reflect it in the ecosystem component table.
The README's API reference was missing the ChatWithTools method, Tool/ToolSchema/ToolCall/ToolResult types, ChatWithToolsRequest/Response types, Agent, Workflow, and StreamReader types. Added ChatWithTools to the Client Methods table, expanded the API Types table, and added a tool-use example to the Quick Start section.
The OpenAPI contract defines on both Session and SessionDetail, but the SDK types omitted it, so persona information was silently dropped on decode. Add the field (omitempty) and assert round-trip in the existing session list/detail tests.
- Add graph.go with execution graph implementation - Add graph_test.go with test coverage - Update README

This PR introduces cross-ecosystem architectural enhancements encompassing Graph Engineering, Loop Engineering, Context Management, and Prompt Frameworks.
What's Included
StateGraphimplementations, A2A protocol support, and Cypher-like DSLs.All changes include appropriate edge-case handling for timeouts, cancellations, and state immutability.
