# My Hook

Detailed documentation goes here...

## What It Does

- Listens for `/new` commands
- Performs some action
- Logs the result

## Requirements

- Node.js must be installed

## Configuration

No configuration needed.

const myHandler = async (event) => {
  // Only trigger on 'new' command
  if (event.type !== "command" || event.action !== "new") {
    return;
  }

  console.log(`[my-hook] New command triggered`);
  console.log(`  Session: ${event.sessionKey}`);
  console.log(`  Timestamp: ${event.timestamp.toISOString()}`);

  // Your custom logic here

  // Optionally send message to user
  event.messages.push("✨ My hook executed!");
};
