CurdX Bridge

Multi-AI Split-Pane Terminal — Claude · Codex · Gemini · OpenCode

One terminal, four AI agents, real collaboration.

Claude, Codex, Gemini, and OpenCode working side by side in one terminal

---

What is this?

CurdX Bridge puts multiple AI coding agents into split terminal panes. You talk to Claude as usual — when you need a second opinion, just say "let Codex review this" or "ask Gemini for ideas". Claude handles the coordination automatically.

No switching tabs. No copy-pasting context. Just talk.

Quick Start

1. Install

macOS / Linux / WSL (bash):

curl -fsSL https://raw.githubusercontent.com/curdx/curdx-bridge/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/curdx/curdx-bridge/main/install.ps1 | iex

2. Run

curdx                                  # Default: Claude + Codex + Gemini
curdx claude codex gemini opencode     # All four providers
curdx claude codex                     # Just two providers
curdx -r                               # Resume previous session
curdx -r claude codex gemini           # Resume with specific providers

That's it. Panes appear, providers boot up, you start talking to Claude.

Flags

Flag	What it does
-r	Resume last session (keeps context)
--no-auto	Disable auto-approve mode

How It Actually Works

You don't need to learn new commands. Just talk to Claude naturally:

You:    Help me refactor this auth module.
Claude: [writes the refactored code]

You:    Let Codex review this.
Claude: [sends diff to Codex, waits for scores]
        Codex scored it 8.5/10. Suggestions: ...

You:    Ask Gemini for alternative naming ideas.
Claude: [asks Gemini asynchronously]
        Gemini suggests: ...

You:    Looks good. Apply Codex's suggestions and commit.
Claude: [makes changes, commits]

That's the whole workflow. Claude is your main interface. Codex, Gemini, and OpenCode are collaborators it can call on.

Behind the scenes

When you say "let Codex review this", Claude uses built-in skills (/cxb-ask, /cxb-reply) to:

1. Send your request to the Codex pane via async protocol
2. Wait for Codex to finish (you can see it working in its pane)
3. Bring the result back into your conversation

Each provider runs in its own pane — you can watch them think in real time.

Roles

Role	Provider	What it does
Designer	Claude	Plans, implements, orchestrates
Reviewer	Codex	Scores code/plans (1-10 rubrics)
Inspiration	Gemini	Brainstorms alternatives (reference only)
Collaborator	OpenCode	Additional AI perspective

The review framework has pass/fail gates — code must score ≥ 7 before shipping. Up to 3 review rounds, then escalates to you.

Commands (for power users)

You rarely need these — Claude handles them — but they exist:

# Direct communication
cxb-codex-ask "message"    # Send to Codex
cxb-gemini-ask "message"    # Send to Gemini
cxb-opencode-ask "message"    # Send to OpenCode
cxb-claude-ask "message"    # Send to Claude

# Check latest replies
cxb-codex-pend / cxb-gemini-pend / cxb-opencode-pend / cxb-claude-pend

# Test connectivity
cxb-codex-ping / cxb-gemini-ping / cxb-opencode-ping / cxb-claude-ping

# Session management
curdx kill              # Kill all sessions
curdx kill codex -f     # Force kill specific provider

Prerequisites

You need	Install with
tmux (or WezTerm)	brew install tmux / apt install tmux
Claude Code	npm install -g @anthropic-ai/claude-code
Codex CLI (optional)	npm install -g @openai/codex
Gemini CLI (optional)	See provider docs
OpenCode CLI (optional)	See provider docs

Make sure each provider CLI works standalone first.

Platforms

macOS (Intel/Apple Silicon) · Linux (x86-64/ARM64) · Windows x86-64 (native PowerShell + WSL)

Configuration

curdx.config

Place in .curdx/curdx.config (project-level) or ~/.curdx/curdx.config (global):

claude codex gemini opencode

Or JSON for advanced options:

{
  "providers": ["claude", "codex", "gemini", "opencode"],
  "flags": { "resume": true, "auto": true }
}

Environment Variables

Variable	What it does
CURDX_DEBUG=1	Debug logging
CURDX_LANG=zh	Force Chinese
CURDX_THEME=dark	Force dark theme

Build from Source

git clone https://github.com/curdx/curdx-bridge.git
cd curdx-bridge
./scripts/build-all.sh

Troubleshooting

Problem	Fix
curdx: command not found	Add ~/.local/bin to $PATH
No panes appear	Install tmux: brew install tmux
Provider unreachable	Run it standalone first (e.g. codex)
Another instance running	curdx kill then retry

Debug mode: CURDX_DEBUG=1 curdx
