Workshop So you think you know Copilot?

A SparkFabrik workshop on GitHub Copilot in Visual Studio Code, beyond code completion: how it works and how to use it across the development cycle.

Luca Lusso showed the three main chat modes and when to use each:

• Ask, to ask questions and reason about the code without changing it.
• Edit, to change the open files under the developer’s control, when the changes are clear.
• Agent, which works across several files and calls external tools to reach a goal.

Then customization. Participants learned to:

• create custom chat modes for specific tasks, such as research or planning;
• direct requests with participants (@workspace, @terminal);
• define reusable custom prompts, called as slash commands;
• set custom instructions with the project guidelines, applied to every request.
