Dead Stock Identifier

Purpose

Identifies SKUs that have positive inventory on hand but have not sold any units in a configurable lookback window. Dead stock ties up capital, warehouse space, and carrying costs. Read-only — no mutations. Provides the data foundation for a markdown or clearance decision.

Prerequisites

Parameters

Safety

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

Workflow Steps

Inputs: first: 250, query: , select sku, inventoryQuantity, inventoryItem { id }, pagination cursor

Expected output: All variants with stock levels; paginate until hasNextPage: false

Inputs: query: "created_at:>=''", first: 250, select lineItems { variant { id }, quantity }, pagination cursor

Expected output: All line items sold in the window to build a "sold variant IDs" set

Inputs: Batch of inventoryItemIds for stocked variants

Expected output: Inventory item cost data for dead stock value calculation

Session Tracking

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

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Dead Stock Identifier                ║
║  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):

══════════════════════════════════════════════
DEAD STOCK REPORT  (no sales in <days_back> days)
  SKUs with stock:       <n>
  SKUs with zero sales:  <n>  (<pct>%)
  Est. dead stock value: $<amount>

  Top dead stock by value:
    "<product>"  SKU: <sku>  Qty: <n>  Value: $<n>
  Output: dead_stock_<date>.csv
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "dead-stock-identifier",
  "store": "<domain>",
  "period_days": 90,
  "stocked_skus": 0,
  "dead_stock_skus": 0,
  "dead_stock_pct": 0,
  "estimated_value": 0,
  "currency": "USD",
  "output_file": "dead_stock_<date>.csv"
}

Output Format

CSV file dead_stock_.csv with columns:

variant_id, sku, product_title, vendor, quantity_on_hand, days_since_last_sale, unit_cost, total_cost_value
