CCB (Claude Codex Bridge)
A terminal workspace where several CLI agents like Codex, Claude and Gemini exchange messages and work on one task under human oversight
Medium risk
We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.
Why this level
- Controls live CLI agent sessions that have access to code and commands
- The background daemon and message queue pass requests between agents automatically without a per-step confirmation
Install
Manual install
npm install -g @seemseam/ccb@latestMain way to install and update.
This is third-party code. Review the repository files before installing.
What it does
CCB runs several CLI agents (Codex, Claude Code, Gemini, Cursor, Qwen and others) in separate terminal panes and gives them a shared message channel to pass requests and results to each other. Each agent stays a full native terminal that the user can see and take over at any moment. A background daemon keeps project state alive even when the UI is closed, and a message queue separates the human's replies from the agents' so a draft is not lost when a message arrives. A mobile app lets you control the agents remotely from a phone.
Who it is for. For developers who run several CLI agents on one project and want to see and control their collaboration from a single place.
Good fit when
- You need several CLI agents to hand tasks to each other in a chain like "Codex assigns, Claude implements, Gemini reviews"
- You want to see every agent's terminal at once and take over any of them by hand
- You run the project in parallel from a phone through the mobile app while agents work on a workstation
Not a fit when
- Only one agent works on one project without exchanging messages with others
- You need simple automation without interactive terminals and manual intervention
- The Windows build is still in beta, so it is early for stable Windows use
Example request
Bring up Codex and Claude panes in CCB for this project: have Codex draft the plan while Claude starts implementing items as they become readyLimitations
It runs on top of already installed and authenticated CLI agents; it does not replace them or supply their keys. The human/agent and agent/agent queues are described by the authors as a first testing version, with no guarantee against race conditions during simultaneous user action. The native Windows build is marked beta and requires Python, WezTerm, Git Bash and Herdr separately.
How to disable. Remove the package with npm uninstall -g @seemseam/ccb; for a release-package or source install use ccb update to roll back, or delete the install directory manually.
Security check
- Controls live CLI agent sessions that have access to code and commands
- The background daemon and message queue pass requests between agents automatically without a per-step confirmation
README in short
The README describes CCB as a lightweight TUI workspace for visible collaboration between CLI agents, covering 16 provider families including Codex, Claude, Gemini, Qwen and Cursor. Key features: stable interaction graphs between agents such as A-to-B-to-C, a background daemon that keeps project state while the UI is closed, a unified human/agent and agent/agent message queue, and a mobile app for remote control. It installs via npm, with release archives and a Windows beta build also available. Updates and rollbacks go through the built-in ccb update command.
FAQ
Is CCB itself an agent?
No, it is a wrapper and communication channel for already installed CLI agents like Codex, Claude Code and Gemini; it does not replace them or execute code itself.
Can an agent be taken over manually?
Yes, each agent runs in a full native terminal that CCB shows as-is rather than emulating, and the user can type into it directly at any time.
