Why would you assume an entire application can be existed in a prompt? Even when I vibe code, I spend significant effort on iteratively adding features, refining design decisions, modifying components, .... Some of this happens by giving the LLM more text prompts, but some of it is providing annotated images, giving references, changing copy, manual editing, reverting to earlier starts when something doesn't work. It's a whole process. Couple that with the non deterministic nature of llms (even if you somehow manage to use the exact same settings) makes sharing a "prompt" meaningless.

Feel free to point your LLM at a repo and ask it to replicate that. But I'd much rather see someone's finished project rather than an idea for a project
