What is Mysti?

Mysti is an open-source VS Code extension that unifies multiple AI coding agents—such as Claude Code CLI and OpenAI Codex—into a collaborative "dream team" that can brainstorm in parallel, debate alternative implementations, auto-detect multiple solution paths for user selection, and offer permission-aware plan suggestions, all within persistent sidebar/tab chat panels.
