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, Kiro).

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

3. Click Add custom agent.

4. Configure the agent:

   • Agent ID: Unique identifier (e.g., my-agent)
   • Display name: Name shown in menus (e.g., My Agent)
   • Path: Command name or absolute path to the agent executable. The command name alone (e.g., opencode) works in many cases. If the agent is not found automatically, set the full path, or click Auto-detect.
   • Arguments: Command-line arguments, one per line (if required)
   • Environment variables: KEY=VALUE pairs, one per line (if required)

Kiro

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.
