## Install

```sh
agentstack add skill-40rty-ai-shopify-admin-skills-shopify-admin-partial-refund-pattern-detector
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

## 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  --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:>='' 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                        ║
║  Started:              ║
╚══════════════════════════════════════════════╝
```

**After each step**, emit:
```
[N/TOTAL]   
          → Params: 
          → Result: 
```

**On completion**, emit:

For `format: human` (default):
```
══════════════════════════════════════════════
PARTIAL REFUND PATTERN REPORT  ( days)
  Partially refunded orders:   
  Flagged (multi-refund):      
  Flagged (high ratio):        
  Repeat-flagged customers:    

  Top flagged customers by amount:
      Orders:   Refunded: $  Ratio: %
  Output: partial_refund_patterns_.csv
══════════════════════════════════════════════
```

For `format: json`, emit:
```json
{
  "skill": "partial-refund-pattern-detector",
  "store": "",
  "period_days": 90,
  "partially_refunded_orders": 0,
  "flagged_multi_refund": 0,
  "flagged_high_ratio": 0,
  "repeat_flagged_customers": 0,
  "output_file": "partial_refund_patterns_.csv"
}
```

## Output Format
CSV file `partial_refund_patterns_.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 |

## Best Practices
- Combine `min_partials: 2` and `ratio_threshold: 0.5` for the most useful signal — single small partial refunds are usually legitimate.
- Sort by `refund_ratio` descending: high ratios on high-value orders are the strongest fraud signal.
- A repeat-flagged customer with `numberOfOrders > 5` is often a chronic complainer, not a fraudster — review the refund notes before action.
- Use this skill quarterly alongside `order-risk-report` to detect post-purchase fraud that fraud filters miss at checkout.
- Refund `note` content frequently reveals the pattern (e.g., "item missing" repeated three times) — read the notes before flagging a customer.
