- Responses API (streaming): MITM bypass path polls MitmStore directly
when custom tools are active, skipping LS step polling entirely.
Streams thinking text deltas in real-time as they arrive from the MITM.
Handles function calls, text response, and thinking/reasoning events.
- Responses API (sync): Same MITM bypass for non-streaming responses.
Polls MitmStore for function calls or completed text before falling
back to LS path.
- Gemini endpoint: MITM bypass polls MitmStore directly for tool call
responses, eliminating LS overhead.
- MitmStore: Added captured_thinking_text field with set/peek/take methods
for real-time thinking text capture from MITM SSE.
- MITM proxy: Now captures both thinking_text and response_text from
StreamingAccumulator into MitmStore when bypass mode is active.
- store.rs: Add tool context storage (active tools, tool config, pending
tool results, call_id mapping, last function calls for history rewrite)
- types.rs: Add tools/tool_choice fields to ResponsesRequest, add
build_function_call_output helper for OpenAI function_call output items
- modify.rs: Replace hardcoded get_weather with dynamic ToolContext
injection. Add openai_tools_to_gemini and openai_tool_choice_to_gemini
converters. Add conversation history rewriting for tool result turns
(replaces fake 'Tool call completed' model turn with real functionCall,
injects functionResponse before last user turn)
- proxy.rs: Build ToolContext from MitmStore before calling modify_request.
Save last_function_calls for history rewriting on subsequent turns
- responses.rs: Store client tools in MitmStore before LS call. Detect
function_call_output in input array for tool result submission. Return
captured functionCalls as OpenAI function_call output items with
generated call_ids and stringified arguments
- gemini.rs: New Gemini-native endpoint (POST /v1/gemini) with zero
format translation. Accepts functionDeclarations directly, returns
functionCall in Gemini format directly
- mod.rs: Wire /v1/gemini route, bump version to 3.3.0
