Guidelines for GitHub Copilot to write comments to achieve self-explanatory code with less comments

# Self-explanatory Code Commenting Instructions

## Core Principle
**Write code that speaks for itself. Comment only when necessary to explain WHY, not WHAT.**
We do not need comments most of the time.

## Commenting Guidelines

### ❌ AVOID These Comment Types

**Obvious Comments**
```javascript
// Bad: States the obvious
let counter = 0;  // Initialize counter to zero
counter++;  // Increment counter by one
```

**Redundant Comments**
```javascript
// Bad: Comment repeats the code
function getUserName() {
    return user.name;  // Return the user's name
}
```
