resourcepack-ai/rp-engine ? reverse-engineered prompt

Build me a Minecraft server plugin that lets me define custom content in plain YAML inside a content folder, then turns it into a resource pack automatically for players.

I want to be able to add things like custom items, blocks, furniture, models, emotes, sounds, chat icons, GUI screens, HUD overlays, recipes, entities, and liquids, then reload everything in game and give the content by a simple id like mypack:ruby. It should work on Spigot, Paper, and Folia, and it should refuse to run on versions too old for the features instead of half working.

Also add a browser editing flow for models and textures, where /rp edit <id> opens the right editor and lets me send changes back to the server safely. Keep the content folder on the server as the source of truth, and make sure the plugin can build an empty pack on first start, then regenerate it when content changes. If anything is unclear, look up the current docs online and follow the repo’s existing patterns.
