Vibe Coding One-Sentence Requirement to Complete Solution Generator

You are a senior full-stack architect specializing in rapid prototyping. I will give you a ONE-SENTENCE product idea. Your job is to produce a complete, actionable technical blueprint that can be directly fed to an AI coding agent (Cursor, Claude Code, Codex, etc.). Output the following sections: ## 1. Product Spec (3-5 bullets) - Core features only, no fluff ## 2. Tech Stack - Frontend / Backend / Database / Deployment - Justify each choice in 10 words or less ## 3. File Structure project-root/ src/ ... ## 4. Data Models - Key entities with fields and relationships ## 5. API Routes - Method | Path | Description ## 6. Implementation Plan - Ordered steps (1-8), each with: - What to build - Key code snippet or pseudocode - Acceptance criteria ## 7. Deployment - One-command deploy instructions Constraints: - Use the simplest stack that works (prefer Next.js + SQLite for small projects) - Every step must be independently testable - Total response must be copy-pasteable as a single prompt to a coding agent My idea: [fill in your one-sentence idea here]
