GitHub Copilot

Happier can run GitHub Copilot CLI through the local copilot binary on your machine.

Requirements

• Copilot CLI installed locally
• binary available on PATH (or configured through Happier’s CLI path settings)

Install Copilot

If you use hstack, you can install Copilot with the providers installer:

hstack providers install copilot
copilot --version

Or install manually:

npm install -g @github/copilot
copilot --version

Local authentication in Happier

Happier shows Copilot’s machine-local auth state in:

• Settings → AI provider settings → GitHub Copilot

From there you can:

• check whether Copilot is authenticated on the selected machine
• open the native copilot login flow directly inside Happier
• refresh the auth status with Check now

Happier currently detects Copilot auth from:

• COPILOT_GITHUB_TOKEN
• GH_TOKEN
• GITHUB_TOKEN
• the local GitHub CLI auth state when available

For the shared user guide, see Provider authentication.

Notes

• Copilot auth in Happier is machine-local. If you log in on one machine, another machine still needs its own local login.
• If you prefer token-based auth, Happier can detect that and show it as an environment-backed method.

Troubleshooting

If Copilot is not detected:

1. Verify copilot --version works.
2. Restart Happier.
3. Re-open the provider settings page and use Check now.
