description: "Reverse-engineer any codebase into a complete Product Requirements Document (PRD). Analyzes routes, components, state management, API integrations, and user interactions to produce business-readable documentation detailed enough for engineers or AI agents to fully reconstruct every page and endpoint. Works with frontend frameworks (React, Vue, Angular, Svelte, Next.js, Nuxt), backend frameworks (NestJS, Django, Express, FastAPI), and fullstack applications. Use when users mention: generate PRD, reverse-engineer requirements, code to documentation, extract product specs from code, document page logic, analyze page fields and interactions, create a functional inventory, write requirements from an existing codebase, document API endpoints, or analyze backend routes."

## Name

Code → PRD

## Description

Reverse-engineer any frontend, backend, or fullstack codebase into a complete Product Requirements Document (PRD). Analyzes routes, components, models, APIs, and user interactions to produce business-readable documentation detailed enough for engineers or AI agents to fully reconstruct every page and endpoint.

# Code → PRD: Reverse-Engineer Any Codebase into Product Requirements

## Features

- **3-phase workflow**: global scan → page-by-page analysis → structured document generation
- **Frontend support**: React, Vue, Angular, Svelte, Next.js (App + Pages Router), Nuxt, SvelteKit, Remix
- **Backend support**: NestJS, Express, Django, Django REST Framework, FastAPI, Flask
- **Fullstack support**: Combined frontend + backend analysis with unified PRD output
- **Mock detection**: Automatically distinguishes real API integrations from mock/fixture data
- **Enum extraction**: Exhaustively lists all status codes, type mappings, and constants
- **Model extraction**: Parses Django models, NestJS entities, Pydantic schemas
- **Automation scripts**: `codebase_analyzer.py` for scanning, `prd_scaffolder.py` for directory generation
- **Quality checklist**: Validation checklist for completeness, accuracy, readability

## Usage

```bash
# Analyze a project and generate PRD skeleton
python3 scripts/codebase_analyzer.py /path/to/project -o analysis.json
python3 scripts/prd_scaffolder.py analysis.json -o prd/ -n "My App"

# Or use the slash command
/code-to-prd /path/to/project
```

## Examples

### Frontend (React)
```bash
/code-to-prd ./src
# → Scans components, routes, API calls, state management
# → Generates prd/ with per-page docs, enum dictionary, API inventory
```

### Backend (Django)
```bash
/code-to-prd ./myproject
# → Detects Django via manage.py, scans urls.py, views.py, models.py
# → Documents endpoints, model schemas, admin config, permissions
```

### Fullstack (Next.js)
```bash
/code-to-prd .
# → Analyzes both app/ pages and api/ routes
# → Generates unified PRD covering UI pages and API endpoints
```

## Role

You are a senior product analyst and technical architect. Your job is to read a frontend codebase, understand every page's business purpose, and produce a complete PRD in **product-manager-friendly language**.

### Dual Audience

1. **Product managers / business stakeholders** — need to understand *what* the system does, not *how*
2. **Engineers / AI agents** — need enough detail to **fully reconstruct** every page's fields, interactions, and relationships

Your document must describe functionality in non-technical language while omitting zero business details.

### Supported Stacks

| Stack | Frameworks |
|-------|-----------|
| **Frontend** | React, Vue, Angular, Svelte, Next.js (App/Pages Router), Nuxt, SvelteKit, Remix, Astro |
| **Backend** | NestJS, Express, Fastify, Django, Django REST Framework, FastAPI, Flask |
| **Fullstack** | Next.js (API routes + pages), Nuxt (server/ + pages/), Django (views + templates) |
