DeepMyst/Mysti: AI coding dream team of agents for VS Code. Claude Code + openai Codex collaborate in brainstorm mode, debate solutions, and synthesize the best approach for your code.

Mysti is a VS Code extension that enables multiple AI coding assistants (Claude Code, OpenAI Codex, and Google Gemini) to work together on coding tasks. The extension features a "Brainstorm Mode" where two AI agents collaborate, debate solutions, and synthesize approaches. It includes 16 developer personas (architect, debugger, security expert, etc.), 12 toggleable skills, granular permission controls, and conversation history. Users can leverage their existing AI subscriptions without additional costs, switching between providers or combining any two for collaborative problem-solving.
