What problem does it solve? Product teams struggle to understand why users drop off after signup, fail to activate, or churn within the first weeks. This Skill provides a systematic behavior design framework (B=MAP) to diagnose retention failures and design fixes grounded in motivation, ability, and prompt analysis. ## Core Features & Use Cases - Retention Diagnostics: Map metrics like low activation, day-1/day-7/day-30 drop-off, and notification fatigue to specific B=MAP failure modes with concrete remediation steps. - Ability Chain Friction Audits: Evaluate six simplicity factors (time, money, physical effort, mental effort, social deviance, non-routine) to find the weakest link blocking key user behaviors. - Tiny Habits Design: Create Starter Steps, anchor moments, and celebration patterns that wire durable user habits without relying on motivation spikes. - Use Case: A SaaS team sees 60% of new users abandon onboarding. Use this Skill to run a friction audit, shrink the first action to a Starter Step, and redesign prompts around real user events. ## Quick Start Analyze why users drop off after their first session in my onboarding flow and recommend fixes using the B=MAP framework.
