Show HN: A prompt generator to help AI agents implement my new email API

A developer built a prompt generator that helps AI agents implement a new email API, dynamically generating an OpenAPI spec to balance detail and flexibility across codebases. The project aims to fill a gap in Firebase's app email capabilities beyond basic auth.

I love building apps with Firebase but felt that, other than basic auth, app emails (notifications, billing etc) were missing. Wanting to implement a solution to this, it got me thinking about how to tell a coding agent about a new api and how to implement it. I dynamically generate an openapi spec via a script and have been playing around with using this spec to then create a prompt generator.

It's not something I've come across before and I can sort of understand why... Generating a prompt that's got enough detail to implement the api but not being too specific so it can be used in many code bases is a fine balance.

I'd be interesting in any feedback on my approach and my execution.
