chris-cadev/first-commit ? reverse-engineered prompt

Build me a simple web app where I can paste a repository URL or name and see the first commit for that repo from GitHub, GitLab, or Bitbucket.

I want the app to fetch the earliest commit it can find, then show the commit message, author, date, and a link to the commit if available. Make the page easy to use, with a clean input box, a submit button, and clear loading and error messages if the repo is private, invalid, or can’t be found. It should work for more than one provider, and handle the differences between them without making me think about it.

Keep the interface lightweight and nice looking, and make sure the backend is set up so it can run locally right away. If you need current API details for the providers, look them up online and use the simplest approach that works.
