Let Claude and OpenAI collaborate on your code from one VS Code panel. Claude plans and reviews; OpenAI models help execute, debug, and generate code. Bring your own API keys.
Features
Auto mode - Routes tasks by intent: Claude for planning/review, OpenAI for implementation/debug support.
Parallel mode - Sends the same prompt to both agents so you can compare answers.
Debate mode - Claude drafts, then OpenAI reviews and improves the response.
Claude Only / Codex Only - Use either provider standalone.
Model picker - Choose Claude and OpenAI models directly in the DualAgent panel.
BYOK - Uses your own Anthropic and OpenAI API keys.
Send selection - Select code and send it with context using the command or shortcut.
Insert code - Insert generated code blocks into the active editor.
