# Churn & Intelligence

Surface retention risk and growth opportunities.

- **churn risk** → `churn_risk` (per-subscriber or fleet-wide ranking with drivers).
- **marketing intelligence** → `marketing_intelligence` for segments, upsell candidates, and campaign ideas.
- **cost / anomaly signals** → `high_cost_subscribers`, `detect_usage_anomalies` (silent churn often shows as a usage drop first).
- **diagnose at-risk accounts** → `diagnose_subscriber` for the top risks.

Deliver a ranked, actionable list: who's at risk, why, and the single best retention action per account (top-up nudge, plan right-size via `optimize_package`, proactive SMS via `send_sms`). Offer to execute the top action.
