💭 Reasoning

I need to help the user create a web scraper for Hacker News homepage. Let me break down what I need to do:

  1. First, understand the existing codebase structure
  2. Check if there's an existing Playwright setup
  3. Use browser tools to understand the Hacker News page structure
  4. Create/update the scraper to extract the top 30 stories with title, URL, points, and comments
  5. Save the data as CSV

Let me start by using the TodoWrite tool to plan this task, then explore the codebase.
