The matrix consists of five questions that test workflow viability, data object mapping, messy edge cases, error states, and scope reduction before engineering time is committed. The process aims to ensure prototypes are robust enough for real user paths, not just polished demos.", "body_md": "The most dangerous AI prototype is not the broken one.\n\nIt is the one that looks finished five minutes too early.\n\nThat is the moment when teams start discussing backlog, polish, and launch timing before anyone has checked whether the workflow can survive a real user path. I have been using [NxCode](https://www.nxcode.io/) a lot for first-pass MVP generation, so I needed a faster way to catch that false sense of completeness.\n\nNow I run a small fallback matrix before a prototype gets engineering time.\n\nI ask 5 questions in order.\n\nThis catches demo-first prototypes.\n\nI rewrite the product in one line:\n\nExample:\n\nIf that sentence is weak, the MVP is still a pitch, not a workflow.\n\nI list the minimum data objects before I judge any UI.\n\nFor a request flow, I usually need:\n\nIf the generated screens do not clearly map to those records, I stop trusting the prototype.\n\nI always test one messy case early:\n\nIf the MVP hides every ugly case, it is optimized for screenshots, not review.\n\nThis is the question that changed my process the most.\n\nI check whether the prototype shows:\n\nWithout that, a smooth happy path can fool me into approving a brittle product.\n\nI do not ask what to add next.\n\nI ask what to remove before the sprint conversation becomes expensive.\n\nMy usual cut list includes:\n\nIf I cannot cut 20 percent of the first version, the scope is still inflated.\n\nThe value is not that NxCode makes judgment unnecessary.\n\nThe value is that it gets me from a rough description to a reviewable app structure quickly enough that I can spend the real time on scope decisions, handoff states, and failure cases.\n\nThat is the useful loop for me:\n\nprompt -> generated MVP -> fallback matrix -> cut list -> better sprint handoff\n\nIf you want to try that workflow, start with [NxCode](https://www.nxcode.io/) and the [getting started docs](https://www.nxcode.io/docs/getting-started).\n\nThe prototype can arrive fast.
