Claude Code Bridge is a native multi-agent runtime that brings parallel AI collaboration to your terminal. Instead of switching between separate tools, you get multiple AI agents running simultaneously in split panes, each with independent roles, personalities, and skill libraries.

Key capabilities include:

Visible Concurrency: Watch all agents work in parallel within terminal split panes—every interaction is transparent and controllable
Native Agent Communication: Agents communicate directly through built-in messaging (/ask all for broadcasts, /ask agent_name for targeted delegation)
Multi-Provider Support: Combine Claude, Codex, Gemini, OpenCode, and Droid in the same workspace
Flexible Configuration: Define agent roles, pane layouts, and workspace modes (in-place or isolated git worktrees) through simple config syntax
Project-Scoped Runtime: Each project maintains its own .ccb state with preserved configuration across rebuilds

The tool excels at complex development workflows where you need different AI specialists working together—a code reviewer agent, a writer agent, and a QA agent can collaborate on the same codebase without conflicts. Simple commands like ccb launch your multi-agent setup, while ccb -s enables safe mode and ccb -n rebuilds project state when needed.
