[bnchrch]

Overview

Takes a feature description or brief and scrapes the product site for context, then generates a full Product Requirements Document including problem statement, user stories, requirements, success metrics, and edge cases.

Input: Feature description or brief (text) + product URL
Output: Full PRD with problem statement, user stories, functional requirements, success metrics, and edge cases

APIs Required

• Scraping: Firecrawl or Jina Reader
• LLM: Anthropic API

Folder Structure

Based on: output-dev-folder-structure skill

This workflow lives at src/workflows/prd_generator/:

• workflow.ts — deterministic orchestration (no I/O, no Date.now(), no Math.random())
• steps.ts — all HTTP, LLM, and external API calls
• types.ts — Zod input/output schemas
• prompts/ — LLM prompt templates (if needed)
• scenarios/ — test input JSON files

Scenario

Based on: output-dev-scenario-file skill

Create src/workflows/prd_generator/scenarios/happy_path.json with a realistic sample input, e.g.:

{
  "featureDescription": "Allow users to export their data as a CSV file from the dashboard",
  "productUrl": "https://yourproduct.com"
}

Test Plan

Based on: output-workflow-run skill

1. Start the dev environment:

   npx output dev

2. No additional credentials needed beyond default LLM credentials.
3. Run with the scenario:

   npx output workflow run prd_generator --scenario happy_path

   Or with inline input:

   npx output workflow run prd_generator --input '{"featureDescription": "Allow users to export their data as a CSV file from the dashboard", "productUrl": "https://yourproduct.com"}'

4. Confirm the output matches the expected schema and content.
