Skill: retention-predictor

Purpose

Retention determines LTV. An app that churns users in week 1 can't build a business regardless of acquisition. This skill evaluates how sticky the idea is structurally — not based on feature lists, but on the underlying usage pattern and habit formation potential.

Input

• Idea slug
• App concept description
• memory/ideas/<slug>/desire_scores.json (desire strength informs habit potential)
• memory/ideas/<slug>/user_extraction.json (usage frequency from pain map)
