Cursor-hosted models (cu/composer-2.5, cu/cursor-grok-*, cu/default) returned HTTP 200 with an empty turn, or hung, whenever a client sent tools. - Fold system prompts into the current user message. custom_system_prompt (RunRequest field 8) makes AgentService return an empty turn. - Send ModelDetails (field 3); thinking variants (Composer, Grok, *-thinking) return an empty turn when only requested_model (field 9) is set. - Route tool-call history and declared tool schemas through AgentService: encode OpenAI tools into mcp_tools (field 4), decode McpArgs and emit real tool_calls with finish_reason tool_calls. - Map Composer thinking / Grok thinking_delta (field 4) into visible content instead of dropping the answer with the unsigned reasoning. - Ack request_context without echoing MCP tools (double-advertise stalls the HTTP/2 stream) and ack kv_server_message so the run proceeds. - Reject IDE builtin execs instead of failing the turn, so the model can continue with MCP tools or a text answer. - Add google.protobuf.Value / MCP encoders and a FIXED64 branch to encodeField in cursorProtobuf.js. RTK now compresses the source-format body before translation for cursor only: its translator rewrites role:tool into user XML, so the post-translate pass missed those tool results. Every other provider keeps the post-translate pass unchanged.

- CORS OPTIONS: 200 response, empty body, correct headers
- Authentication: missing key, bad format, old-format key, wrong key value, valid key
- Body validation: invalid JSON, missing model, missing input, bad model
- Happy path: single string, array, correct delegation, CORS header, machineId override
- Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
- Error propagation: non-fallback errors passed through, 429 exhausts accounts
- machineId override: validates key, rejects wrong key
