How I Built a Multi-Agent System for Converting Ideas into Structured Artifacts

I split one vague task ("validate my startup idea") across five focused AI agents instead of one mega-prompt. A research analyst writes structured JSON, a pitch agent turns it into a real .pptx, a skeptical-VC agent fires hard questions, a designer agent ships an HTML landing page, and a consultant agent chats over the same context. Each agent produces a real file the next one consumes. It's a Flask app on Azure OpenAI, the whole run takes under a minute, and the honest caveats are in the last section.
