Same PRD → bootable FastAPI app, zero LLM calls (600-line Python)

This devtool takes a Product Requirements Document (PRD) and automatically generates a fully bootable FastAPI application in a single 600-line Python file, without making any LLM calls. It is designed for developers who want to rapidly prototype backend services from structured specifications, bypassing the cost, latency, and unpredictability of AI-generated code. The project is interesting because it demonstrates a deterministic, rule-based approach to code generation that is both transparent and instantly executable.
