shopify-admin-discount-hygiene-cleanup

Purpose

Audits the discount catalog for expired codes, codes with zero redemptions, and duplicate code prefixes. Discount sprawl accumulates over months of campaigns and makes the admin difficult to navigate. Optionally deletes flagged codes. Replaces manual discount cleanup and builds on the discount-ab-analysis skill with a write step.

Prerequisites

• Authenticated Shopify CLI session: shopify store auth --store <domain> --scopes read_discounts,write_discounts
• API scopes: read_discounts, write_discounts

Parameters

Parameter	Type	Required	Default	Description
store	string	yes	—	Store domain (e.g., mystore.myshopify.com)
flag_expired	bool	no	true	Flag/delete discounts past their end date
flag_zero_usage	bool	no	true	Flag/delete discounts with 0 redemptions older than N days
zero_usage_min_age_days	integer	no	30	Age threshold for zero-usage flags
dry_run	bool	no	true	Preview without executing mutations
format	string	no	human	Output format: human or json

Safety

⚠️ discountCodeDelete permanently removes discount codes. Deleted codes cannot be recovered. Customers who received a deleted code will find it invalid. Run with dry_run: true to review the flagged list before committing. Always check that expired codes are not referenced in active email campaigns before deleting.

Workflow Steps

1. OPERATION: discountNodes — query Inputs: first: 250, select discount { ... on DiscountCodeBasic { codes, usageLimit, asyncUsageCount, endsAt, status } }, pagination cursor Expected output: All discount codes with usage and expiry data; paginate until hasNextPage: false

2. Flag discounts matching: flag_expired (status = EXPIRED) and/or flag_zero_usage (asyncUsageCount == 0 AND created > zero_usage_min_age_days ago)

3. OPERATION: discountCodeDelete — mutation Inputs: id: <discount_node_id> Expected output: deletedCodeDiscountId, userErrors

Session Tracking

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

On start, emit:

╔══════════════════════════════════════════════╗
║  SKILL: Discount Hygiene Cleanup             ║
║  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
  Discounts scanned:     <n>
  Expired:               <n>
  Zero usage (> <n> days): <n>
  Total flagged:         <n>
  Deleted:               <n>
  Errors:                <n>
  Output:                discount_cleanup_<date>.csv
══════════════════════════════════════════════

For format: json, emit:

{
  "skill": "discount-hygiene-cleanup",
  "store": "<domain>",
  "started_at": "<ISO8601>",
  "dry_run": true,
  "outcome": {
    "scanned": 0,
    "flagged_expired": 0,
    "flagged_zero_usage": 0,
    "deleted": 0,
    "errors": 0,
    "output_file": "discount_cleanup_<date>.csv"
  }
}

Output Format

CSV file discount_cleanup_<YYYY-MM-DD>.csv with columns: discount_id, title, status, created_at, ends_at, usage_count, usage_limit, flag_reason, action

Error Handling

Error	Cause	Recovery
THROTTLED	API rate limit exceeded	Wait 2 seconds, retry up to 3 times
userErrors on delete	Discount already deleted or active order using it	Log error, skip, continue
No discounts flagged	Clean discount catalog	Exit with ✅ no cleanup needed

Best Practices

• Run quarterly — discount code sprawl accumulates quickly with seasonal campaigns.
• Check with your email marketing team before deleting zero-usage codes — they may be in a scheduled campaign that hasn't launched yet.
• Keep flag_zero_usage age at 30+ days to avoid deleting codes from recently launched campaigns.
• Automatic/percentage discounts (not code-based) are not cleaned up by this skill — those are managed separately.
