why

Before this PR:

Extracted data: {
  name: 'Asim Shrestha',
  content: "I'm a software engineer co-founding Reworkd",
  page_links: [
    { title: 'Reworkd', url: 'https://reworkd.ai/' },
    { title: 'Writing', url: 'https://asim-shrestha.com/writing' },
    { title: 'Quotes', url: 'https://asim-shrestha.com/quotes' },
    { title: 'Reading', url: 'https://asim-shrestha.com/reading-list' },
    { title: 'Contact', url: 'https://asim-shrestha.com/contact' }
  ]
}

After this PR:

Extracted data: {
  name: 'Asim Shrestha',
  content: 'Asim Shrestha is a software engineer co-founding Reworkd, a YC S23 company that focuses on extracting structured data from the web. They are known for developing AgentGPT 🤖.',
  page_links: [
    { title: 'Reworkd', url: 'https://reworkd.ai/' },
    { title: 'Writing', url: 'https://asim-shrestha.com/writing' },
    { title: 'Quotes', url: 'https://asim-shrestha.com/quotes' },
    { title: 'Reading', url: 'https://asim-shrestha.com/reading-list' },
    { title: 'Contact', url: 'https://asim-shrestha.com/contact' }
  ]
}

what changed

Make isTopElement check if the element is top in multiple points in the bounding triangle instead of just the center.

The test case is still failing but because we have an extra link extract ({ title: 'Reworkd', url: 'https://reworkd.ai/' }). But this seems reasonable enough to me / doesn't seem like something we want to add to the prompt (since the user at times might want to get the current page url)

Can you run the evals a few times to ensure it's stable? When I run on my local it doesn't match your results.

• extract_collaborators_from_github_repository: Fails on my local, passes on yours, fails on main
• extract_last_twenty_github_commits: **Fails on my local, passes on main, fails on yours. **
• google_jobs: Passed on my local, passes on main, fails on yours
• bananalyzer_1: Fails on my local, fails on main, passed on your run.
