Anthropic API

Type: <b>Bug</b>

I have not found a reliable AI assistant that knows how to use an Anthropic API code for with Copilot. I have tried Claude, Continue, Google Gemini, Crok, and CoPilot. None of these is able to provide correct instruction that is acccurate and matches with VS Code menus and settings. I spent 8 hours atempting to user my API code with Copilot without success.

Extension version: 2.0.47
VS Code version: Code 1.106.2 (1e3c50d64110be466c0b4a45222e81d2c9352888, 2025-11-19T16:56:50.023Z)
