VS Code Adapter

The FORG VS Code extension hooks into the VS Code extension API to capture AI usage from GitHub Copilot, Copilot Chat, and other language model extensions. It works by observing VS Code's lm (language model) API requests.

Prerequisites

VS Code 1.85.0 or later
FORG CLI installed and activated
GitHub Copilot or another VS Code AI extension installed

Installation

Install from the VS Code Marketplace:

# Via VS Code command palette:
ext install forg-pro.forg-vscode

# Via CLI:
code --install-extension forg-pro.forg-vscode

After installation, VS Code will prompt you to confirm the FORG agent connection. Click Allow. The extension connects to the local agent at127.0.0.1:6247.

Configuration

Open VS Code settings (Cmd+,) and search for "FORG", or edit settings.json:

{
  "forg.enabled": true,
  "forg.projectId": "proj_my-vscode-project",
  "forg.captureInlineCompletions": false,
  "forg.logLevel": "info"
}

Setting	Default	Description
`forg.enabled`	`true`	Enable/disable the extension
`forg.projectId`	null	Override project ID for all signals from this workspace
`forg.captureInlineCompletions`	`false`	Whether to emit signals for inline completions (high volume)
`forg.agentPort`	`6247`	Local agent port override

What gets captured

GitHub Copilot Chat interactions (all models)
Copilot Edits sessions
VS Code lm.sendRequest calls from any extension
Optionally: inline completion requests (disabled by default due to volume)

Verification

Check the FORG status bar item in VS Code (bottom bar). It shows:

Green dot = agent connected, signals flowing
Yellow dot = agent connected, no recent signals
Red dot = agent not reachable

Troubleshooting

Issue	Resolution
Status bar shows red dot	Run `forg status` to confirm agent is running. Restart VS Code if needed.
Copilot signals missing	Ensure Copilot is signed in and active. FORG can only capture calls that go through the VS Code `lm` API.
Extension not appearing	Check `Extensions: Show Installed` for "FORG". Reload window after install.
