Enhance your GitHub Copilot experience with community-contributed instructions, prompts, and configurations. Get consistent AI assistance that follows your team's coding standards and project requirements.

GitHub Copilot provides three main ways to customize AI responses and tailor assistance to your specific workflows, team guidelines, and project requirements:

💡 Pro Tip: Custom instructions only affect Copilot Chat (not inline code completions). You can combine all three customization types - use custom instructions for general guidelines, prompt files for specific tasks, and chat modes to control the interaction context.

We welcome contributions! Please see our Contributing Guide for details on how to submit new instructions and prompts.
