Skills allow Copilot to perform specialized tasks.

Custom agents enhance Copilot with assistance tailored to your needs.

Access a running Copilot CLI session from GitHub.com or GitHub Mobile to monitor and steer the session when you are away from the machine where the session is running.

Modify Copilot's behavior and abilities when it works on particular tasks.

Give Copilot additional context on how to understand your project and how to build, test and validate its changes.
