feat: Gemini grounding and metered Live session client - #36
Conversation
This change introduces a new Gemini integration module that enables the agent to interact with Google's Gemini API. The implementation provides the necessary request and response handling to support agent conversations through the Gemini service. Auto-committed-on: dragonfly
…ion endpoints Add support for the Gemini integration within the agent integrations API, including endpoints for creating and querying live sessions and generating content. This enables users to interact with Gemini models for real-time conversations, transcription, and content generation with grounding support. Auto-committed-on: dragonfly
Reformatted the `body_json` call in the Gemini live session route test to span multiple lines, improving code readability without changing any behavior. Auto-committed-on: dragonfly
…endpoints The assertion for the number of unexposed routes is updated from 59 to 61 to account for the addition of PUT and DELETE operations on the orchestrator token registration endpoint, which are synced alongside the Gemini routes. Auto-committed-on: dragonfly
The GeminiLiveConversation variant in the GeminiLiveSessionRequest enum is now boxed to reduce the size of the enum, preventing potential stack overflows when the conversation struct grows. The test and OpenAPI sync assertions are updated to reflect the new operation counts from the added Gemini routes. Auto-committed-on: dragonfly
Adds documentation for the Gemini API integration, covering the three main endpoints: generate content, live session creation, and session status retrieval. This includes details on tool support, pricing, WebSocket relay behavior, and close codes to help users understand the integration's capabilities and constraints. Auto-committed-on: dragonfly
Tiny Sweeper reviewAdds Gemini API integration with grounded `generateContent` and a metered Live session client. The new module provides typed request/response models, route registration, and documentation for the Gemini agent integration endpoints. State: Ready for maintainer review Review snapshot
Completeness: Complete What changedAdded a new `gemini` module (`src/api/agent_integrations/gemini.rs`) with typed models for `GenerateContentRequest`, `LiveSessionRequest`, `LiveTicket`, `LiveSession`, and helper methods. Updated `mod.rs` and `agent_integration_types.rs` to export the module. Registered three new public routes in `generated_public_routes.rs` (`POST .../gemini/models/{model}/generate-content`, `POST .../gemini/live/sessions`, `GET .../gemini/live/sessions/{sessionId}`). Updated operation count assertions in `tests/openapi_sync.rs` and `src/lib.rs`. Added documentation in `docs/api-surface.md`. Features

Align the Gemini documentation with the deployed API contract.
The deployed Swagger document contains no Gemini paths, while this section documents Gemini generation and Live-session endpoints. Before publishing, add the routes to the deployed contract or remove the undocumented routes from this section. The current evidence does not establish that production routes are unavailable.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Exclude thought parts from text().
When the caller sets generationConfig.thinkingConfig.includeThoughts, Gemini returns thought summaries as parts with a text field and "thought": true. The current text() helper concatenates those parts with the answer. The caller then gets the model's reasoning mixed into the final text. Google's SDKs skip parts where thought is true when they build response.text. Add the same filter here so the helper follows the same contract.
🐛 Proposed fix

.iter()
+ .filter(|p| !p.get("thought").and_then(Value::as_bool).unwrap_or(false))

Typed client for the backend's new Gemini agent integration (tinyhumansai/backend PR to follow, branch feat/gemini-api).
New module agent_integrations::gemini:
Route registry resynced from the backend branch's spec with --input. This adds the 3 Gemini routes and 2 service-token routes already on backend main (PUT/DELETE /opencompany/orchestrators/{id}/token) to the blocklist, so the pinned counts move: UNEXPOSED_ROUTES 59 -> 61, operationCount 208 -> 211, excludedAdminOperationCount 47 -> 49.
The crate has no raw WebSocket dependency, so connecting to the relay is left to the caller; docs/api-surface.md describes the protocol.
Testing: cargo fmt --check, cargo clippy --all-targets -D warnings, cargo test (new wiremock tests for all three routes plus the module layout test), sync-openapi --check against the branch spec reports no drift.
