Frequently Asked Questions
What is the difference between Copilot coding agent and agent mode?
Agent mode runs inside your IDE and works interactively like pair programming. Copilot coding agent runs asynchronously on GitHub Actions — you assign it a task, walk away, and come back to a ready pull request. Think of agent mode as a co-driver and coding agent as a teammate working on their own ticket.
Is GitHub Copilot coding agent free?
Not entirely. The coding agent is available on all paid Copilot plans — Pro ($10/month), Pro+ ($39/month), Business, and Enterprise. Verified students get free access through Copilot Student. Each coding agent session uses one premium request from your plan's allowance.
How do I assign an issue to Copilot coding agent?
Open any GitHub issue and set the assignee to "Copilot." The agent picks up the issue, creates a branch prefixed with copilot/, works through the task, and opens a pull request. You can also trigger it from VS Code, the GitHub Agents panel, or by commenting @copilot on an existing PR.
What tasks is Copilot coding agent best for?
It excels at low-to-medium complexity tasks in well-tested codebases — adding features, fixing bugs, writing tests, refactoring, and improving documentation. Avoid assigning open-ended architecture decisions or tasks that require deep product context.
Can Copilot coding agent run tests automatically?
Yes. The agent has access to an ephemeral development environment powered by GitHub Actions where it can run your test suite, linters, and other checks. It iterates on failures until tests pass before opening a pull request.
