description: "Reorder products in a manual Shopify collection by inventory level, moving in-stock products to the top and out-of-stock to the bottom."
toolkit: shopify-admin, shopify-admin-execution

status: stable
compatibility: Claude Code, Cursor, Codex, Gemini CLI

Purpose

Reorders products in a manual Shopify collection by inventory level without navigating the Shopify admin UI. This skill queries all products in the collection, computes the desired sort order by `totalInventory`, and applies it in a single `collectionReorderProducts` mutation. Note: only works on manual (custom) collections — smart collections managed by Shopify rules are not supported.

Prerequisites

• Authenticated Shopify CLI session: `shopify auth login --store <domain>`
• API scopes: `read_products`, `write_products`

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 | | collection_id | string | yes | — | GID of the manual collection (e.g., `gid://shopify/Collection/123`) | | sort_by | string | no | inventory_desc | `inventory_desc` (highest stock first) or `inventory_asc` (lowest stock first) |

Safety

> ⚠️ Step 2 executes `collectionReorderProducts` which changes the product display order immediately. The sort is reversible — run again with the opposite `sort_by` to restore previous order — but the original custom order cannot be recovered once overwritten. The `moves` array passed to the mutation must be complete; partial moves produce undefined ordering. Always run with `dry_run: true` first to review the computed sort order before committing.

`collectionReorderProducts` only works on manual (custom) collections. If the collection has `sortOrder` other than `MANUAL`, the skill must abort with a clear message: "Cannot reorder: collection sort order is not MANUAL. Switch the collection to manual sorting in the Shopify admin first."

Workflow Steps

1. **OPERATION:** `collection` — query **Inputs:** `id: <collection_id>`, `first: 250`, pagination cursor **Expected output:** Collection metadata (title, `sortOrder`) and all product nodes with `totalInventory`; verify `sortOrder == "MANUAL"` — abort if not; paginate until all products fetched

2. **OPERATION:** `collectionReorderProducts` — mutation **Inputs:** `id: <collection_id>`, `moves` array sorted by `totalInventory` per `sort_by` parameter — each move is `{id: <product_id>, newPosition: "<index>"}` (0-indexed string) **Expected output:** `job.id` and `job.done`; `userErrors`

GraphQL Operations

# collection:query — validated against api_version 2025-01
query CollectionProducts($id: ID!, $first: Int!, $after: String) {
  collection(id: $id) {
    id
    title
    sortOrder
    products(first: $first, after: $after) {
      edges {
        node {
          id
          title
          totalInventory
          variants(first: 100) {

              node {
                inventoryQuantity
              }
            }
          }
        }
      }
      pageInfo {
        hasNextPage
        endCursor
      }
    }

# collectionReorderProducts:mutation — validated against api_version 2025-01
mutation CollectionReorderProducts($id: ID!, $moves: [MoveInput!]!) {
  collectionReorderProducts(id: $id, moves: $moves) {
    job {

      done
    }
    userErrors {

Session Tracking

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

**On start**, emit:

╔══════════════════════════════════════════════╗
║  SKILL: collection-reorganization            ║
║  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>

If `dry_run: true`, prefix every mutation step with `[DRY RUN]` and do not execute it.

**On completion**, emit:

For `format: human` (default):

══════════════════════════════════════════════
OUTCOME SUMMARY
  Collection:          <title>
  Products reordered:  <n>
  Sort order:          <inventory_desc|inventory_asc>
  Errors:              0
  Output:              none
══════════════════════════════════════════════

For `format: json`, emit:

{
  "skill": "collection-reorganization",
  "store": "<domain>",
  "started_at": "<ISO8601>",
  "completed_at": "<ISO8601>",
  "dry_run": false,
  "steps": [
    { "step": 1, "operation": "CollectionProducts", "type": "query", "params_summary": "collection_id: <gid>, first: 250", "result_summary": "<n> products fetched", "skipped": false },
    { "step": 2, "operation": "CollectionReorderProducts", "type": "mutation", "params_summary": "sort_by: inventory_desc, <n> moves", "result_summary": "job submitted", "skipped": false }
  ],
  "outcome": {
    "collection_title": "<title>",
    "products_reordered": 0,
    "sort_by": "inventory_desc",
    "errors": 0,
    "output_file": null
  }
}

Output Format

No CSV output. The skill reports the new sort order in the session completion summary. Use `dry_run: true` to preview the computed position list without committing.

Error Handling

| Error | Cause | Recovery | |-------|-------|----------| | `sortOrder is not MANUAL` | Collection is a smart/automated collection | Switch collection to manual ordering in Shopify admin | | `userErrors` in mutation | Invalid product ID or po
