Yesterday I posted a prompt framework for starting any project. Today I used it in real time to scope an entire product from scratch. Here's exactly what happened. I sat down with Claude and asked a simple question: "Can you be a Dungeon Master?" That's it. No project brief. No feature list. No business plan. Just a question. Within 10 minutes, I had a working prototype. A full game interface with character creation, dice rolling, an animated DM avatar, and AI-powered narrative. Built as an artifact, playable right there in the chat. But here's where the process kicked in. I looked at the prototype and started asking better questions. Not "what can it do" but "how would real people actually use this?" And that changed everything. "It needs two modes. One for a group at a table, one for online play." "I see this running on a monitor at the head of the table." "People should be able to upload their adventure and the AI reads them." "Voice. It has to talk back. That's non-negotiable." "What about someone who's never played before?" Each answer revealed the next question. Each question sharpened the product. Then I let the AI interview ME. Nine targeted questions about how the game should feel, who the first users are, what happens when the AI makes a bad call, how sessions start and end. My answers defined features I never would have sat down and brainstormed: > A table vote system where players can override the AI's rulings and create house rules that persist across campaigns > A session pacing engine that knows you have 2 hours and structures the story accordingly > Session recaps with highlights (Best Roll, Worst Roll, Coolest Move) that people will screenshot and share > A first-time player mode that teaches the rules through play, not tutorials > A "Game Brain" that gets smarter from every session played across every table (same architecture as the Shop Brain I built for my auto shop product Torq) By the end I had a 15-section product architecture document. Voice-first AI Game Master. System-agnostic (works with any tabletop RPG, not just D&D). Jackbox-style room codes for joining. File import that builds worlds from uploaded adventure modules. LLM-agnostic so users can bring their own AI provider. Free and open-source with a premium hosted version.
