Install in Google Antigravity

Google Antigravity is Google's agentic development platform built on VS Code. It uses the Open VSX Registry by default, where SF Veritas is available.

Prerequisites​

Antigravity connects to Open VSX Registry by default, so you can install directly:

Method 1: Search in Antigravity​

  1. Open Google Antigravity
  2. Open the Extensions view:
    • Click the Extensions icon in the Activity Bar, or
    • Press Ctrl+Shift+X (Windows/Linux) or Cmd+Shift+X (macOS)
  3. Search for "SF Veritas"
  4. Click Install on the "SF Veritas" extension
  5. The extension will activate automatically

Method 2: Using the Antigravity CLI​

Antigravity includes its own CLI for extension management:

antigravity --install-extension sailfish-ai.sf-veritas-extension

On macOS, the CLI is located at:

/Applications/Antigravity.app/Contents/Resources/app/bin/antigravity

You may want to add it to your PATH for easier access.

Alternative: Install from VSIX​

If you prefer to install from a VSIX file:

  1. Download the VSIX file from Open VSX
  2. In Antigravity, open the Extensions view (Ctrl+Shift+X / Cmd+Shift+X)
  3. Click the ... (More Actions) button
  4. Select "Install from VSIX..."
  5. Navigate to and select the downloaded VSIX file
  6. Click Install and reload when prompted

Or via CLI:

antigravity --install-extension /path/to/sf-veritas-extension-x.x.x.vsix

Verify Installation​

  1. Look for the SF Veritas icon in the Activity Bar
  2. Open the Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
  3. Type "SF Veritas" and verify you see these commands:
    • SF Veritas: Show Console Logs
    • SF Veritas: Show Flamechart
    • SF Veritas: Start Local Server

Configuration​

After installation, configure the extension through Antigravity settings:

  1. Open Settings (Ctrl+, / Cmd+,)
  2. Search for "SF Veritas"
  3. Key settings include:
    • Local Mode: Enable/disable the local telemetry server (default: enabled)
    • Auto Start Server: Automatically start the server when Antigravity opens (default: enabled)
    • Local Server Port: Port for the telemetry server (default: 6776)

Antigravity-Specific Notes​

Using VS Code Marketplace Instead of Open VSX​

VS Code Marketplace Access

If you prefer to use the VS Code Marketplace (which has more extensions available), you can configure Antigravity to connect to it:

  1. Open Antigravity Settings (Ctrl+, / Cmd+,)
  2. Go to the Editor tab
  3. Update these settings:
    • Marketplace Item URL: https://marketplace.visualstudio.com/items
    • Marketplace Gallery URL: https://marketplace.visualstudio.com/_apis/public/gallery
  4. Restart Antigravity

After this change, you can search for and install extensions directly from the VS Code Marketplace.

VS Code Compatibility​

Since Antigravity is built on VS Code, SF Veritas features work the same way:

  • Console view for logs
  • Flamechart visualization
  • Click-to-navigate to source code
  • All VS Code keyboard shortcuts

Extension Registry​

Antigravity uses Open VSX by default. If SF Veritas doesn't appear in search:

  1. Verify your Antigravity version is up to date
  2. Try installing via CLI or VSIX as alternatives

Troubleshooting​

  1. Check that Open VSX is accessible from your network
  2. Try the CLI installation method
  3. Download and install the VSIX manually

Extension not loading​

  1. Restart Antigravity after installation
  2. Check the Output panel → "SF Veritas" for error messages
  3. Verify the extension is enabled in the Extensions view

Port 6776 already in use​

If another application is using port 6776:

  1. Open Antigravity Settings
  2. Search for sfVeritas.localServerPort
  3. Change to an available port (e.g., 6777)
  4. Restart the local server via Command Palette: SF Veritas: Restart Local Server
