Who is it for?

Developers who want help understanding an unfamiliar function while keeping its source and callers open in their editor.
Teams comparing assistance for small fixes or test drafts, with someone available to check behavior and maintain the resulting code.

Getting started

Use the current VS Code setup guide, enable Copilot and sign in with the GitHub account that has the intended access. Check work-account policies before opening private code.
Prepare one failing example, the relevant files, dependency versions and expected output. Remove credentials from logs and state what the change must preserve.
Ask for an explanation or a focused edit first. For a task spanning files, define the allowed scope before choosing an agent and inspect any command it proposes.
Read the complete diff, including generated tests and dependency changes. Run the original failure and a nearby edge case; keep a change only when you can explain why it works.

Decision points

Choose inline assistance when you are already writing a function; choose chat when you need to discuss why it behaves a certain way. Broader edits need a clear acceptance condition.
Compare an editor assistant with a browser app builder using where the code must live and who will review it. Copilot is a closer fit when you already maintain a repository and local tooling.

Limits

Generated code can be incorrect. A convincing explanation is not evidence that a proposed fix meets your requirements.
Availability varies by plan, client version and organization policy. Check the current allowance and required capability before committing to a workflow; no fixed free quota is asserted here.
This guide reviews official documentation, not an installation or coding trial. Output quality, offline operation and natural-language coverage have not been verified.

Frequently asked questions

Is this the same product as Microsoft Copilot?

No. This record covers GitHub Copilot in VS Code. Microsoft Copilot has a separate catalog record; its access and features should not be transferred to this coding extension.

How should I evaluate it before changing a real project?

Use a small copy of code whose expected behavior you already know. Ask for one change, review its diff and run a test you wrote independently. Compare the effort of reviewing the result with doing the task yourself.
