[plan] Add PRD generation workflow for Ralph Loop

[github-actions]

Objective

Create a workflow that generates a structured PRD (Product Requirements Document) in JSON format, similar to Ralph's prd.json.

Context

Ralph uses a skill to convert markdown PRDs into structured JSON with user stories. We need a workflow that takes a feature description and generates a PRD suitable for the Ralph Loop workflow.

Approach

1. Create .github/workflows/ralph-prd-generator.md that:

   • Takes a feature description as input
   • Uses AI engine to generate structured PRD
   • Asks clarifying questions if needed
   • Outputs prd.json with user stories format:

     {
       "feature": "...",
       "branchName": "...",
       "userStories": [
         {
           "id": 1,
           "title": "...",
           "description": "...",
           "acceptanceCriteria": [],
           "passes": false
         }
       ]
     }

2. Include validation to ensure tasks are small and atomic

3. Add examples in examples/ralph/prd-samples/

Files to Create

• .github/workflows/ralph-prd-generator.md - PRD generation workflow
• examples/ralph/prd-samples/feature-example.md - Sample input
• examples/ralph/prd-samples/prd-output.json - Sample output

Acceptance Criteria

• Workflow generates structured PRD from description
• PRD includes properly formatted user stories
• Each story has title, description, criteria, and passes flag
• Workflow validates stories are appropriately sized
• Examples demonstrate various feature types
