When to use this skill

Use this skill when the user wants to add a new functional command (e.g., "Hello World", "Format Text") to the extension.

How to use this skill

Adding a command requires updates to two files: package.json and src/extension.ts.

Step 1: Update package.json

Add the command definition to the contributes.commands array.

// package.json
{
  "contributes": {
    "commands": [
      {
        "command": "extension.myCommand", // Unique ID
        "title": "My Extension: Do Something" // Display Name
      }
    ]
  }
}

Step 2: Update src/extension.ts

Register the command in the activate function.

// src/extension.ts
import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    // ... existing code ...

    let disposable = vscode.commands.registerCommand('extension.myCommand', () => {
        // Implementation logic here
        vscode.window.showInformationMessage('Command executed!');
    });

    context.subscriptions.push(disposable);
}

Best Practices

• Command ID Naming: Use extensionName.actionName format to avoid conflicts.
• Async Handling: If the command logic is asynchronous, use async () => { await ... }.
• Error Handling: Wrap logic in try-catch blocks if it involves external operations.
