ai-stockflow-builder

Commission an interactive stock-flow simulation web app from your AI coding agent (Claude Code or Codex). Use when the user wants to turn a hand-drawn or W2-graded stock-flow diagram into a runnable simulation with sliders. Triggers on Russian and English requests like "построй симуляцию моей модели", "сделай симуляцию из диаграммы", "build a simulation of my stock-flow model", "turn my diagram into code", "сделай интерактивную модель", "stock-flow simulation app", "system dynamics simulator". Refuses to invent equations, parameters, or model structure - those come from the human's diagram. Gates on a measurable, time-bound goal carrying a contradiction (an antagonist to the key parameter) before building - a model with no contradiction is arithmetic, not system dynamics. Refuses to ship code without a successful hand-computed extraction test.
