🤖 GitHub Copilot Assets Library

Enhance your GitHub Copilot experience with comprehensive instructions, prompts, chat modes, and configurations. Get consistent AI assistance that follows your team's coding standards and project requirements for development, architecture, planning, and documentation tasks.

There are many ways GitHub Copilot can be used to help you with not just your coding tasks, but also with ideation, problem solving, understanding, planning, research and so much more.

The biggest challenge is either creating or finding the right prompts and tools to get the most out of GitHub Copilot - and when to use them.

I've spent many hours building my own tools and prompts and chat modes to help me with my work, and I want to share them with you.

[!NOTE] I created this repository without knowing the GitHub team had plans to release a similar library https://github.com/github/awesome-copilot. However, I am planning to migrate all the resource from this repository over to the Github Awesome Copilot repository in the future. So, you will start seeing duplicated content in both repositories.

I am considering retaining this repository to enhance it with more detailed pages on each chat mode, prompt file showing usage examples. As what is possible with these modes often require more detailed examination and demonstrations.

🎯 GitHub Copilot Customization Features

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

| 🔧 Custom Instructions | 📝 Prompt Files (Reusable Prompts) | 🧩 Custom Chat Modes | 🔌 MCP Servers | | --- | --- | --- | --- | | Define common guidelines for tasks like code generation, reviews, and commit messages. Describe how tasks should be performed<br><br>Benefits:<br>• Automatic inclusion in every chat request<br>• Repository-wide consistency<br>• Multiple implementation options | Create reusable, standalone prompts for specific tasks. Describe what should be done with optional task-specific guidelines<br><br>Benefits:<br>• Eliminate repetitive prompt writing<br>• Shareable across teams<br>• Support for variables and dependencies | Define chat behavior, available tools, and codebase interaction patterns within specific boundaries for each request<br><br>Benefits:<br>• Context-aware assistance<br>• Tool configuration<br>• Role-specific workflows | Extend GitHub Copilot agents with standardized tools, resources, and prompts via Model Context Protocol for specialized tasks and external integrations<br><br>Benefits:<br>• Invoke tools for databases, APIs, and file operations<br>• Access external resources as chat context<br>• Pre-configured prompts for complex workflows<br>• Tool confirmation and parameter editing<br>• Automatic discovery and workspace sharing |

💡 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.
