✨ AI GitHub Copilot VS Code Chat Modes

• Founder: Abdullah Khawer - LinkedIn

Introduction

A curated collection of custom chat modes based on chatmode.md files for Visual Studio Code (VS Code) used by GitHub Copilot to enhance your development using AI to work smarter.

Custom chat modes allow you to modify GitHub Copilot's behavior in VS Code. Each chatMode.md file builds a specialized AI assistant with targeted knowledge and abilities for your development work, significantly cutting development time by eliminating repetitive manual tasks.
