Prerequisites

TermMate connects to external CLI-based agents to drive its core capabilities. Complete the steps below before starting a chat session.

1. Install TermMate

Sublime Text

Install TermMate via Package Control:

Open the Command Palette (Cmd+Shift+P on macOS, Ctrl+Shift+P on Windows/Linux).
Type Package Control: Install Package and press Enter.
Search for TermMate and press Enter.

VS Code

Install TermMate from the Visual Studio Code Marketplace: marketplace.visualstudio.com → TermMate Or search TermMate directly in the VS Code Extensions panel (Cmd+Shift+X).

2. Install Agent CLI

The easiest way to install an agent is directly from within your editor: open the Command Palette, type TermMate: Install Agent, and select the agent you want. TermMate will run the installation in a dedicated panel and notify you when it’s complete. You can also run TermMate: Install Agent at any time later to add more agents. Or install manually from your terminal:

Pi Agent

TermMate automatically detects CLI installation paths across multiple environments, including Homebrew, npm-global, Yarn, and common local binary directories. You typically don’t need to manually configure environment variables or search paths.

3. Authentication

Once installed, authenticate the agents via your terminal before starting a session in TermMate. Alternatively, you can skip CLI login by setting API keys directly in TermMate’s settings (Preferences → Package Settings → TermMate → Settings):

{
    "env": {
        "ANTHROPIC_API_KEY": "sk-ant-...",
        "OPENAI_API_KEY": "sk-...",
        "GEMINI_API_KEY": "your-gemini-api-key"
    }
}
