In this lesson

Prepare for the GH-300 exam (GitHub Copilot certification). In this lesson: slash commands (/explain, /fix, /tests, /fixTestFailure, /new, /clear), chat variables and participants, chat limits and history, custom instructions (repository-wide, path-specific, agent, personal and organization instructions), and reusable prompt files. Includes three original practice questions.

Preview the topics
  • A developer wants Copilot Chat to help build a command that finds large files, using the context of their terminal. Which participant fits?
  • A team wants every Copilot Chat request in its repository to follow its coding standards, without repeating them. What should it add?
  • A team runs the same detailed review prompt every week, and wants everyone to run exactly the same one from chat. What should it create?
