Copilot

Over the past year, the mainstream way developers interact with AI for programming has gone through a clear evolution: Prompt -> Prompt Engineering -> Context Engineering -> Skill (Capability Packaging) If a prompt is a one-off invocation of model capability, then a Skill is essentially a reusable intelligent capability module. It enables AI to evolve from “answering questions” to “executing tasks.” This article will systematically explain: What a Skill means in the context of AI programming The fundamental difference between a Skill and a prompt How to apply Skill thinking in VS Code + GitHub Copilot Chat Real engineering-level examples What Is a Skill?...

As AI coding assistants continue to evolve, GitHub Copilot keeps introducing more powerful models for developers to choose from. Recently, GitHub Copilot announced support for Google’s latest Gemini 3 Pro model (Preview). As a developer who uses Copilot daily, I tried it out immediately and found it surprisingly good at logical reasoning and long context understanding. In this post, I’ll guide you through switching to Gemini 3 Pro in VS Code and share some of my insights....
