How does the context routing work?

The skill automatically scans specific folders in your workspace (like /thoughts/shared/pm/) for strategy frameworks, research, and past decisions to find contradictions.

Can I customize which files the skill reviews?

Yes, you can paste content directly, specify a file path, or let it automatically find the most recently modified PRD in your project.

What kind of feedback should I expect?

You receive a structured markdown report with 'Critical', 'Important', and 'Minor' issues, plus a set of unanswered questions and a 'what actually works' section.
