watabou/TownGeneratorOS ? reverse-engineered prompt

Build me a medieval fantasy city generator that makes interesting random towns and cities from a seed, so I can keep regenerating the same layout or make new ones until I like it.

I want it to feel like the classic fantasy city map tool, with streets, districts, walls, gates, and other city details drawn automatically in a nice top down style. Let me control the city size and generate a new result quickly. If you can, make it easy to share a seed or open a saved city again later.

Keep the focus on the generator itself, and don’t worry about the newer extras like water areas or a big options panel unless they are already simple to add. If you need to check current docs for the tools or libraries, go ahead and look them up online.
