GitHub Copilot CLI

Install

npm install -g @github/copilot

The worker looks for copilot on the worker user's PATH.

Sign-in

Start copilot once as the worker's user and run /login, or put COPILOT_GITHUB_TOKEN (or GH_TOKEN) in the task's environment profile. Without either a run ends with "No authentication information found".

How it runs

copilot --allow-all-tools --no-ask-user --no-auto-update --no-color --output-format json [--model <model>] [--add-dir <dir>] -p <prompt>

• --allow-all-tools is required for non-interactive mode, and --no-ask-user keeps it from waiting for an answer.
• --no-auto-update keeps the version the worker reported from changing under a running task.
• Projects with several repositories reach it: the other repositories are passed with --add-dir.

Add-on models

Copilot CLI has a custom-provider mode: with COPILOT_PROVIDER_BASE_URL set it uses that endpoint instead of GitHub's model routing and needs no GitHub login. The worker sets COPILOT_PROVIDER_BASE_URL, COPILOT_PROVIDER_TYPE, COPILOT_PROVIDER_API_KEY and COPILOT_MODEL for gateway sessions, and the same variables for the providers it uses directly (OpenAI, OpenAI-compatible, Ollama, Anthropic). A complete task was run for the gateway and for each of those four against a test endpoint.

Sessions

Resume is not claimed for GitHub Copilot CLI: no resume command could be verified without an account. After a crash, recovery starts a fresh session from the checkpoint.

What was verified

Checked against GitHub Copilot CLI 1.0.92 on 2026-10-06: its --help, and a real run without credentials through the worker's session runtime. It also completed a task through the model gateway against a test model.
