Churn Risk Scorer
Read-only: scores customers by churn probability based on purchase recency, frequency decay, and expected repurchase intervals.
shopify-admin-churn-risk-scorer
Purpose
Predicts which customers are at risk of churning by analyzing their purchase patterns against their historical buying frequency. Calculates an expected next-purchase date for each repeat customer, then scores churn risk based on how overdue they are. Read-only — no mutations.
Prerequisites
shopify store auth --store --scopes read_orders,read_customers read_orders, read_customersParameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain |
| days_back | integer | no | 365 | Historical window for purchase pattern analysis |
| min_orders | integer | no | 2 | Minimum orders to calculate purchase interval (need 2+ for frequency) |
| risk_threshold | float | no | 1.5 | Multiplier of avg purchase interval before flagging as at-risk |
| format | string | no | human | Output format: human or json |
Safety
> ℹ️ Read-only skill — no mutations are executed. Safe to run at any time.
Churn Risk Scoring Model
For each customer with min_orders or more purchases:
Workflow Steps
orders — query Inputs: query: "created_at:>=', first: 250, select createdAt, totalPriceSet, customer { id, email, firstName, lastName }, pagination cursor
Expected output: All orders with customer association
customers — query (enrichment)Inputs: Customer IDs for at-risk and likely-churned segments
Expected output: Contact details, tags, total spend
GraphQL Operations
# orders:query — validated against api_version 2025-01
query OrdersForChurnAnalysis($query: String!, $after: String) {
orders(first: 250, after: $after, query: $query) {

customer {

Session Tracking
Claude MUST emit the following output at each stage. This is mandatory.
On start, emit:
╔══════════════════════════════════════════════╗
║ SKILL: Churn Risk Scorer ║
║ Store: <store domain> ║
║ Started: <YYYY-MM-DD HH:MM UTC> ║
╚══════════════════════════════════════════════╝
After each step, emit:
[N/TOTAL] <QUERY|MUTATION> <OperationName>
→ Params: <brief summary of key inputs>
→ Result: <count or outcome>
On completion, emit:
For format: human (default):
══════════════════════════════════════════════

Repeat customers scored: <n>
─────────────────────────────
Active (score 0-20): <n> (<pct>%)
Cooling (score 20-50): <n> (<pct>%)
At Risk (score 50-80): <n> (<pct>%) ⚠️
Likely Churned (80-100): <n> (<pct>%) 🔴
Revenue at risk: $<amount>/year
Top at-risk by value:

Output: churn_risk_<date>.csv
══════════════════════════════════════════════
Output Format
CSV file churn_risk_ with columns:
customer_id, email, first_name, last_name, order_count, total_spent, avg_purchase_interval_days, days_since_last_order, overdue_ratio, churn_risk_score, risk_segment, expected_annual_value
Error Handling
| Error | Cause | Recovery |
|---|---|---|
THROTTLED | API rate limit exceeded | Wait 2 seconds, retry up to 3 times |
| Single-purchase customers | Can't calculate interval | Exclude from scoring (need 2+ orders) |
| Guest orders | No customer linkage | Skip — cannot build customer profile |
Best Practices
