Shopify Admin Delivery Time Analysis

Purpose

Analyzes fulfilled orders to calculate average transit time (fulfillment created → delivered) broken down by carrier. Surfaces which carriers are consistently slow or missing delivery confirmations. Read-only — no mutations.

Prerequisites

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

Parameters

Safety

ℹ️ Read-only skill — no mutations are executed. Safe to run at any time.

Workflow Steps

1. OPERATION: orders — query Inputs: query: "fulfillment_status:shipped created_at:>='<NOW - days_back days>'", first: 250, pagination cursor Expected output: Orders with fulfillments { createdAt, updatedAt, deliveredAt, trackingInfo { company } }; paginate until hasNextPage: false

2. Calculate transit times per carrier: deliveredAt - createdAt (skip orders where deliveredAt is null)

3. OPERATION: fulfillmentOrders — query (optional, for location breakdown) Inputs: assignedLocationId: <location_id>, status: CLOSED, first: 250 Expected output: Fulfilled orders per location for location-level segmentation

Session Tracking

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

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Delivery Time Analysis               ║
║  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):

══════════════════════════════════════════════
DELIVERY TIME ANALYSIS  (<days_back> days)
  Orders analyzed:     <n>
  With delivery data:  <n>

  FedEx                <n>     <d>       <d>  <d>
  (carriers below min_orders threshold excluded)
  Output: delivery_analysis_<date>.csv
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "delivery-time-analysis",
  "store": "<domain>",
  "period_days": 30,
  "carriers": [
    { "name": "UPS", "orders": 0, "avg_days": 0, "min_days": 0, "max_days": 0 }
  ],
  "output_file": "delivery_analysis_<date>.csv"
}

Output Format

CSV file delivery_analysis_<YYYY-MM-DD>.csv with columns: order_name, fulfillment_id, carrier, fulfilled_at, delivered_at, transit_days

Error Handling

Best Practices

• Set min_orders: 10 for statistically meaningful averages — carriers with fewer orders will skew results.
• deliveredAt is populated only when the carrier confirms delivery via tracking events; some carriers do not report this, so null values are expected.
• Run monthly to track carrier performance over time and inform carrier contract negotiations.
• Cross-reference with the wismo-bulk-status-report skill to correlate slow delivery carriers with WISMO ticket volume.
