Retention Loop Design Skill

Acquisition without retention is a leaky bucket — you pay to fill it and it drains. This skill diagnoses where and why users drop, then designs the loop that makes the product habitual: the trigger that brings them back, the value they get, and the investment that makes the next visit more likely. Retention is the truest measure of product-market fit.

Required Inputs

Ask for these only if they aren't already provided:

• The retention curve — how usage decays over time (D1/D7/D30, or weekly cohorts); does it flatten or go to zero?
• The core value & natural frequency — what users come for, and how often they'd genuinely need it.
• Activation definition — the early action that correlates with sticking (or note it's unknown).
• Current loops — any notifications, streaks, or re-engagement already in place.
