How does it leverage past project knowledge?

It scans lessons.json and the last 100 lines of your progress logs to find recurring patterns, then flags any new stories that fail to implement those specific learnings.

Do I need a specific file structure for this skill?

Yes, it operates within the RALPH framework, requiring a .ralph directory containing prd.json and optional files like lessons.json and suggested-lessons.txt.

What does the /prd-check command do?

It validates your .ralph/prd.json file for structural integrity and ensures each user story accounts for known project lessons and failure patterns.

Can this skill automatically fix my PRD issues?

Yes. After identifying structural issues or missing constraints, the skill will ask for your permission to write the fixes directly back to the .ralph/prd.json file.

Security & Testing

Validates product requirement documents against structural standards and historical project lessons to ensure high-quality coding stories.

This skill provides a rigorous validation layer for your development workflow by analyzing PRDs before code generation begins. It goes beyond simple syntax checking by cross-referencing your project's historical failures, learned patterns, and suggested improvements from previous iterations. By identifying missing acceptance criteria, security constraints, or architectural patterns early, it ensures that the autonomous agent has a robust roadmap, minimizing rework and preventing the repetition of past mistakes within the RALPH agentic loop.
