v2.13.0 - Native Tools, Responses API & Stability Fixes

What's New in v2.13.0 🚀

✨ New Features

• VS Code Native Tools Support: The API Gateway now fully exposes native vscode.lm.tools alongside standard MCP tools. You can list them via GET /v1/tools and invoke them via POST /v1/tools/call. The gateway also routes and executes them seamlessly during internal Copilot chat workflows!
• Message Author Attribution: The name field from OpenAI-compatible message arrays is now properly forwarded to GitHub Copilot, preserving contextual author attribution in complex multi-agent prompts.
• Developer Performance Tools: Exposed powerful developer performance monitoring commands in the Command Palette (e.g., Reset Perf Metrics, Start CPU Profile, Get Perf Metrics) prefixed with Copilot API (Dev):.
• System Prompt Editing: You can now easily access and edit the default system prompt directly via the Command Palette command Copilot API: Edit Default System Prompt.

🐛 Bug Fixes & Improvements

• Streaming Stability: Added robust safeguards against EPIPE and write-after-end crashes. The gateway now handles sudden client disconnects during active LLM streams gracefully without crashing the extension process.
• Google Streaming Fixes: Fixed an issue where finishReason was incorrectly emitted in intermediate chunks during Google streamGenerateContent operations, resolving downstream LangChain and client parser compatibility issues.
• Responses API Stubs: Added explicit 501 Not Implemented stubs for GET /v1/responses/{id} and DELETE /v1/responses/{id} to enforce and document the stateless architecture of the gateway.
• Improved Request Telemetry: Refined usage telemetry tracking to collect compliant, anonymized metrics (durationBucket, isStreaming, modelFamily, and HTTP status codes) without ever collecting PII or prompts.
• Dependencies Update: Updated @vscode/extension-telemetry to the latest 1.5.2.
