agent-bridge

Connect AI agents together. Let Claude Code delegate tasks to GPT, Gemini, and more.

agent-bridge is a Claude Code plugin that bridges different AI agents, allowing them to collaborate on your tasks. When Claude gets stuck on a bug, needs a second opinion, or when you want a specific model's perspective — just delegate the task to another agent without leaving your workflow.

Why?

Every AI model has strengths. GPT excels at certain reasoning tasks. Gemini brings its own perspective. Instead of switching between terminals and copy-pasting context, agent-bridge lets Claude hand off tasks directly to other AI CLIs and bring back the results.

You → Claude Code → agent-bridge → Codex CLI (GPT) → results back to Claude
                                  → Gemini CLI      → results back to Claude

Supported Agents

Agent	CLI	Models
codex	OpenAI Codex CLI	gpt-5.4, gpt-5.3-codex, gpt-5.3-codex-spark
gemini	Google Gemini CLI	gemini-2.5-pro, gemini-2.5-flash, gemini-3-pro, gemini-3-flash, gemini-3.1-pro-preview

Install

From Claude Code (recommended)

/plugin marketplace add Kira-Pgr/agent-bridge
/plugin install agent-bridge

One-liner

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

Prerequisites

• Claude Code v1.0.33+
• At least one agent CLI installed:
  • Codex: npm install -g @openai/codex then codex login
  • Gemini: npm install -g @google/gemini-cli then run gemini once to authenticate

How It Works

1. You ask Claude to delegate a task to Codex or Gemini
2. Claude asks you which model and settings to use (via interactive prompt)
3. A bridge subagent spawns and runs the external CLI
4. Results come back to Claude, who summarizes what happened

The plugin uses a SessionStart hook to inject instructions into Claude's context, so Claude knows to ask for your model preferences before delegating.

Usage

Ask Claude naturally:

• "Run this through Codex for a second opinion"
• "Ask Gemini to review this function"
• "Delegate this bug to GPT — I'm stuck"

Or spawn agents directly:

• agent-bridge:codex — delegates to OpenAI Codex CLI
• agent-bridge:gemini — delegates to Google Gemini CLI

Adding a New Agent

Want to bridge another AI CLI? It's straightforward:

1. Create agents/<name>.md with the agent definition (see existing agents for the pattern)
2. Add the path to plugin.json agents array
3. Update scripts/session-context.sh with the new agent's model options
4. Submit a PR
