Retention is the most important growth metric and the least often diagnosed. Teams report monthly retention number; they do not read the curve. Without the curve, the team does not know when users churn and what activities correlate with the ones who stay.

The /surge-retention skill reads cohort retention curves by acquisition channel and behavior segment. Maps activities that correlate with retention vs churn. Produces a playbook with re-engagement triggers, win-back sequences, and habit loop recommendations.

Tonone's /surge-retention skill diagnoses retention curves and produces a re-engagement and habit-loop playbook.
