I got tired of copy-pasting between Claude and Codex so I built a VS Code extension that makes them talk to each other

DualAgent runs both agents in one panel inside VS Code. You pick the mode:

• Auto — smart routing, Claude reasons, Codex codes
• Parallel — both agents answer at the same time
• Debate — Claude drafts → Codex critiques → you get the best of both

BYOK (bring your own API keys), completely free, no subscription.

Built and shipped it today. Still early — would genuinely love to hear what you'd want from a dual-agent coding tool.
