find-companies— agent skill

You can fetch https://companiesmarketcap.com/tech/largest-tech-companies-by-market-cap to get an HTML document, which you'll need to reason about. The document should contain a table containing rows with info about tech companies. Your job is to find this list of companies and extract them into a list of just the company names. You should see a pagination link (e.g. "Next") below the list of jobs. Get the next page as well so we have a decent amount to work with.

From there, you need to figure out if they have jobs posted on commonly-used job posting sites (please do this in a single python script to avoid the user needing to confirm many commands):

1. Greenhouse: fetch https://boards-api.greenhouse.io/v1/boards/{COMPANY_NAME} to determine whether the company has jobs listed on Greenhouse
2. Lever: run a HEAD request to https://jobs.lever.co/{COMPANY_NAME} (to keep requests lightweight) to determine whether the company has jobs listed on lever
3. Ashby: fetch https://api.ashbyhq.com/posting-api/job-board/{COMPANY_NAME} — returns 200 if the company has an Ashby board, 404 if not. (Do NOT use a HEAD request to jobs.ashbyhq.com — that site is a SPA and returns 200 for all paths regardless of whether the company exists.)

Then write any companies you found, along with their jobs board type to src/.generated/company-listings.ts. Do NOT modify the Typescript types in this file.
