Custom Agents Setup

You can use any agent that implements the Agent Client Protocol (ACP).

Install and Configure

1. Install your ACP-compatible agent (e.g., OpenCode, Qwen Code).

2. Find the installation path:

macOS/Linux

which your-agent
# Example output: /usr/local/bin/your-agent

Windows

where.exe your-agent
# Example output: C:\Users\Username\AppData\Roaming\npm\your-agent.cmd

3. Open Settings → Agent Client and scroll to Custom Agents section.

4. Click Add custom agent.

5. Configure the agent:

   • Agent ID: Unique identifier (e.g., my-agent)
   • Display name: Name shown in menus (e.g., My Agent)
   • Path: Absolute path to the agent executable
   • Arguments: Command-line arguments, one per line (if required)
   • Environment variables: KEY=VALUE pairs, one per line (if required)

Authentication

Authentication depends on the specific agent. Common patterns:

• API Key: Add to Environment variables (e.g., MY_API_KEY=xxx)
• Account Login: Run the agent's CLI to authenticate, then leave environment variables empty

Refer to your agent's documentation for specific authentication instructions.

Verify Setup

1. Click the robot icon in the ribbon or use the command palette: "Open agent chat"
2. Select your custom agent from the agent dropdown in the chat header
3. Try sending a message to verify the connection
