shopify-admin-top-product-performance

Purpose

Ranks products by revenue, units sold, and refund rate for a given date range by aggregating order line items and refund line items across all orders in the period. Useful for identifying top performers and products with high refund rates. Read-only — no mutations are executed.

Prerequisites

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

Parameters

Parameter	Type	Required	Default	Description
store	string	yes	—	Store domain (e.g., mystore.myshopify.com)
format	string	no	human	Output format: human or json
dry_run	bool	no	false	Preview operations without executing mutations
date_range_start	string	yes	—	Start date in ISO 8601 (e.g., 2025-01-01)
date_range_end	string	yes	—	End date in ISO 8601 (e.g., 2025-01-31)
top_n	integer	no	20	Number of top products to show in the ranked output
sort_by	string	no	revenue	Ranking metric: revenue, units, or refund_rate

Workflow Steps

1. OPERATION: orders — query Inputs: first: 250, query: "created_at:>='<date_range_start>' created_at:<='<date_range_end>'", pagination cursor Expected output: All orders in range with line items (title, quantity, originalTotalSet, refundableQuantity) and refund line items; paginate until hasNextPage: false; aggregate in-memory per product: sum originalTotalSet for gross revenue, sum refund amounts for net revenue, sum quantities for units sold, compute refund rate

}

Session Tracking

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

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: top-product-performance              ║
║  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):

══════════════════════════════════════════════
OUTCOME SUMMARY
  Orders processed:   <n>
  Products ranked:    <n>
  Date range:         <start> to <end>
  Sort by:            <revenue|units|refund_rate>
  Errors:             0
  Output:             none
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "top-product-performance",
  "store": "<domain>",
  "started_at": "<ISO8601>",
  "completed_at": "<ISO8601>",
  "dry_run": false,
  "steps": [
    { "step": 1, "operation": "OrdersForProductPerformance", "type": "query", "params_summary": "<date_range_start> to <date_range_end>", "result_summary": "<n> orders processed", "skipped": false }
  ],
  "outcome": {
    "orders_processed": 0,
    "products_ranked": 0,
    "date_range_start": "<date_range_start>",
    "date_range_end": "<date_range_end>",
    "sort_by": "revenue",
    "results": [],
    "errors": 0,
    "output_file": null
  }
}

Output Format

Ranked table displayed inline (no CSV), truncated to top_n entries:

Rank	Product	Units Sold	Gross Revenue	Refunded Amount	Net Revenue	Refund Rate %
1	...	...	...	...	...	...

For format: json, results is an array of objects with keys: rank, product_id, product_title, units_sold, gross_revenue, refunded_amount, net_revenue, refund_rate_pct.

Error Handling

Error	Cause	Recovery
No orders returned	No orders in date range	Widen date range
variant is null on a line item	Product or variant was deleted	Still aggregated by title; product_id will be null
Rate limit (429)	Too many paginated requests	Narrow date range

Best Practices

1. For stores with many orders, use a 30-day window first. Wider windows paginate more aggressively and take longer.
2. sort_by: refund_rate highlights products with quality or expectation issues — a refund rate above 10% is worth investigating.
3. Revenue figures are gross (before refunds) and net (after refunds) — use net revenue for accurate profitability ranking.
4. Products that have been deleted will still appear if they were purchased in the date range — they show with product_id: null and their title from the order line item.
5. Combine with discount-ab-analysis to see which discount codes drove the most revenue for your top products.
