How to Improve the Quality of Suggestions from GitHub Copilot

Introduction

GitHub Copilot is a smart tool that helps developers by providing code suggestions as they type. To make the most out of GitHub Copilot, you can follow a few simple steps that will improve the quality of its suggestions.

Tips

Tip 1. Write Clear and Concise Code

Well-structured code makes it easier for GitHub Copilot to understand your intent. Use meaningful variable and function names, follow consistent coding styles, and avoid unnecessary complexity. The clearer your code, the better Copilot’s suggestions will be.

Tip 2. Provide Context with Comments

Copilot benefits from extra context. Adding comments—especially before complex logic—helps it generate more relevant suggestions. For example, writing a short comment explaining a function’s purpose can lead to better auto-generated code.

Tip 3. Use Common Libraries and Frameworks

Copilot has been trained on widely used libraries and frameworks. Sticking to standard, well-documented libraries (like NumPy in Python or Entity Framework in .NET) increases the likelihood of receiving accurate and useful suggestions.

Tip 4. Keep Your Codebase Clean

A well-maintained codebase allows Copilot to function more effectively. Regularly refactor and remove redundant code to improve both readability and AI-generated recommendations.

Tip 5. Customize Copilot Settings

GitHub Copilot allows customization to better align with your coding style. Explore its settings to tweak how suggestions are provided, enabling or disabling features as needed.

Tip 6. Provide Feedback to Improve Suggestions

Each time you accept, modify, or reject a suggestion, Copilot learns from your preferences. Using Copilot’s feedback options helps refine its future recommendations, making it more tailored to your coding style.

Conclusion

By following these best practices—writing clear code, adding comments, using popular libraries, maintaining a clean codebase, customizing settings, and providing feedback—you can significantly enhance Copilot’s performance. This leads to faster coding, fewer errors, and a more seamless development experience.
