Lecture 1: What is AI Skill? Why You Must Learn It Now?

This lecture is the starting point of the entire course, helping you build a complete understanding of AI Skills.

1. What is a Skill?

1.1 A Simple Metaphor

Imagine you hired an all-capable assistant:

You say "convert this PDF to Word", it completes immediately
You say "organize my meeting notes from this week", it processes automatically
You ask "how do I sum this Excel spreadsheet", it guides you step by step

This assistant doesn't need salary, won't get tired, available 24 hours — this is AI Skill.

1.2 Technical Definition

AI Skill (技能) is a functional plugin running on top of AI large models, which:

🎯 Understands user's natural language instructions
🔧 Calls corresponding tools and capabilities
✅ Completes specific task goals

User says: "Merge these 3 Excel files"
    ↓
AI Skill understands intent (Intent: merge files)
    ↓
Calls tools (Tool: Excel processing library)
    ↓
Executes actions (Action: read→merge→save)
    ↓
Returns result: "Merged successfully, download link: xxx"
