What problem does it solve? Users sign up but fail to stick around: activation rates stall, onboarding creates friction, and cohort retention curves drop after day one. This Skill diagnoses why target behaviors are not happening and prescribes concrete fixes using behavior design. ## Core Features & Use Cases - B=MAP Diagnosis: Evaluate any product behavior against Motivation, Ability, and Prompt to find which element sits below the Action Line. - Ability Chain Friction Audits: Rate six simplicity factors (time, money, physical effort, mental effort, social deviance, non-routine) to locate the weakest link blocking activation. - Tiny Habits & Prompt Design: Build anchor-based habit recipes with Starter Steps and celebration, and design event-based prompts that avoid notification fatigue. - Use Case: A SaaS team sees day-7 drop-off. The Skill maps the metric to a B=MAP diagnosis (motivation wave receded, core action too hard), runs a friction audit on onboarding, and prescribes a Starter Step plus anchor-based prompts. ## Quick Start Ask the assistant to diagnose why new users are not completing onboarding and to recommend fixes using the B=MAP behavior model.
