name: shopify-admin-partial-refund-pattern-detector
role: order-intelligence
description: "Read-only: surfaces orders with multiple partial refunds or unusually high partial-refund-to-total ratios that may indicate fraud, chronic complaints, or process gaps."
toolkit: shopify-admin, shopify-admin-execution
api_version: "2025-01"
graphql_operations:
  - orders:query
status: stable
compatibility: Claude Code, Cursor, Codex, Gemini CLI

Purpose

Scans recent orders, extracts every refund, and flags orders that have either (a) two or more partial refunds, or (b) a partial-refund-to-order-total ratio above a configurable threshold. These patterns frequently indicate friendly fraud (incremental claims), an unhappy repeat customer pattern, or a staff workflow gap (refunding piecemeal instead of issuing one full credit). Read-only — no mutations.

Prerequisites

• Authenticated Shopify CLI session: `shopify store auth --store <domain> --scopes read_orders`
• API scopes: `read_orders`

Parameters

| Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | store | string | yes | — | Store domain (e.g., mystore.myshopify.com) | | days_back | integer | no | 90 | Lookback window for orders to analyze | | min_partials | integer | no | 2 | Minimum number of partial refunds to flag an order | | ratio_threshold | float | no | 0.5 | Flag orders where total refunded / order total exceeds this ratio (still partial, i.e. below 1.0) | | min_order_value | float | no | 25 | Skip low-value orders below this amount | | format | string | no | human | Output format: `human` or `json` |

Safety

> ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. Flagged orders are advisory — confirm with refund notes and customer history before taking action against a customer account.

Workflow Steps

1. **OPERATION:** `orders` — query **Inputs:** `query: "created_at:>='<NOW - days_back days>' financial_status:partially_refunded"`, `first: 250`, select `refunds { id, createdAt, totalRefundedSet, note }`, `totalPriceSet`, `customer`, pagination cursor **Expected output:** All partially refunded orders with full refund history; paginate until `hasNextPage: false`

2. For each order, count refunds and sum `totalRefundedSet.shopMoney.amount`. Compute `ratio = total_refunded / order_total`.

3. Flag orders meeting either condition: `refund_count >= min_partials` OR `ratio >= ratio_threshold` (and `ratio < 1.0` so fully refunded orders are excluded).

4. Group flagged orders by `customer.id` to surface repeat-offender customers (more than one flagged order in the window).

Session Tracking

**Claude MUST emit the following output at each stage. This is mandatory.**

**On start**, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Partial Refund Pattern Detector      ║
║  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):

══════════════════════════════════════════════
PARTIAL REFUND PATTERN REPORT  (<days_back> days)
  Partially refunded orders:   <n>
  Flagged (multi-refund):      <n>
  Flagged (high ratio):        <n>
  Repeat-flagged customers:    <n>

  Top flagged customers by amount:
    <customer>  Orders: <n>  Refunded: $<n>  Ratio: <pct>%
  Output: partial_refund_patterns_<date>.csv
══════════════════════════════════════════════

For `format: json`, emit:

{
  "skill": "partial-refund-pattern-detector",
  "store": "<domain>",
  "period_days": 90,
  "partially_refunded_orders": 0,
  "flagged_multi_refund": 0,
  "flagged_high_ratio": 0,
  "repeat_flagged_customers": 0,
  "output_file": "partial_refund_patterns_<date>.csv"
}

Output Format

CSV file `partial_refund_patterns_<YYYY-MM-DD>.csv` with columns: `order_name`, `order_id`, `customer_email`, `customer_lifetime_orders`, `order_total`, `total_refunded`, `refund_ratio`, `refund_count`, `flag_reason`, `first_refund_at`, `last_refund_at`

Error Handling

| Error | Cause | Recovery | |-------|-------|----------| | `THROTTLED` | API rate limit exceeded | Wait 2 seconds, retry up to 3 times | | Order has refund but `totalRefundedSet` is zero | Refund recorded as $0 (note only, no money moved) | Skip from ratio calc, count refund | | Customer is null (guest order) | No customer attached | Group by email instead of customer ID | | No partially refunded orders | Clean window | Exit with summary: 0 flagged |
