Other Editors

Symposium works with any editor that supports ACP. See the editors on ACP page for a list of supported editors and how to install ACP support.

Installation

1. Install ACP support in your editor of choice
2. Install the Symposium agent binary:

   or from source:

3. Configure your editor to run:

   ~/.cargo/bin/symposium-acp-agent run
   

Instructions for configuring ACP support in common editors can be found here:

• RustRover, IntelliJ, and other JetBrains IDEs
• NeoVim (CodeCompanion)
• Emacs (agent-shell)

After selecting an agent, Symposium creates the config file and you can restart your editor to start using it.

Manual Configuration

You can edit ~/.symposium/config.jsonc directly for more control. The format is:

  "agent": "npx -y @zed-industries/claude-code-acp",
  "proxies": [
    { "name": "sparkle", "enabled": true },
    { "name": "ferris", "enabled": true },
    { "name": "cargo", "enabled": true }
  ]
}

Fields:

• agent: The command to run your downstream AI agent. This is passed to the shell, so you can use any command that works in your terminal.
