Github Copilot

What is GitHub Copilot?

GitHub Copilot is GitHub's AI coding assistant. It provides access to Copilot models for your GitHub account and plan. Reeve can use Copilot as a model provider in two different ways.

Two ways to use Copilot in Reeve

1) Built-in GitHub Copilot provider (github-copilot)

Use the native device-login flow to obtain a GitHub token, then exchange it for Copilot API tokens when Reeve runs. This is the default and simplest path because it does not require VS Code.

2) Copilot Proxy plugin (copilot-proxy)

Use the Copilot Proxy VS Code extension as a local bridge. Reeve talks to the proxy’s /v1 endpoint and uses the model list you configure there. Choose this when you already run Copilot Proxy in VS Code or need to route through it. You must enable the plugin and keep the VS Code extension running.

Use GitHub Copilot as a model provider (github-copilot). The login command runs the GitHub device flow, saves an auth profile, and updates your config to use that profile.

CLI setup

reeve models auth login-github-copilot

You'll be prompted to visit a URL and enter a one-time code. Keep the terminal open until it completes.

Optional flags

reeve models auth login-github-copilot --profile-id github-copilot:work
reeve models auth login-github-copilot --yes

Set a default model

reeve models set github-copilot/gpt-4o

Config snippet

{
  agents: { defaults: { model: { primary: "github-copilot/gpt-4o" } } }
}

Notes

• Requires an interactive TTY; run it directly in a terminal.
• Copilot model availability depends on your plan; if a model is rejected, try another ID (for example github-copilot/gpt-4.1).
• The login stores a GitHub token in the auth profile store and exchanges it for a Copilot API token when Reeve runs.
