Purpose
Identifies variants with a compareAtPrice that no longer represents a genuine discount and clears it, so storefront strikethrough pricing reflects real savings rather than legacy noise. Two conditions are flagged: (a) compareAtPrice <= price (no discount, often left over from a price increase), and (b) compareAtPrice set for longer than max_age_days (stale "always on sale" optics that hurt long-term price perception and can violate advertising standards in some regions). Defaults to dry-run.
Prerequisites
- Authenticated Shopify CLI session:
shopify store auth --store <domain> --scopes read_products,write_products - API scopes:
read_products,write_products
Parameters
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
| store | string | yes | — | Store domain (e.g., mystore.myshopify.com) |
| dry_run | bool | no | true | Preview the cleanup without executing mutations |
| clean_no_discount | bool | no | true | Clear compareAtPrice when price >= compareAtPrice |
| clean_stale | bool | no | true | Clear compareAtPrice set longer than max_age_days |
| max_age_days | integer | no | 90 | Age threshold in days for the stale rule (uses variant updatedAt as proxy) |
| collection_id | string | no | — | Optional collection GID to scope the cleanup |
| tag_filter | string | no | — | Optional product tag to scope the cleanup |
| format | string | no | human | Output format: human or json |
Safety
⚠️ Step 2 executes
productVariantsBulkUpdatemutations that overwritecompareAtPriceto null. The original strikethrough value is not preserved server-side — record the dry-run CSV before committing if you want a restore path. Always start withdry_run: trueand review the CSV before running withdry_run: false.

Session Tracking
Claude MUST emit the following output at each stage. This is mandatory.
On start, emit:
╔══════════════════════════════════════════════╗
║ SKILL: Compare-At Price 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):
══════════════════════════════════════════════
COMPARE-AT PRICE CLEANUP (<dry-run|live>)
Variants inspected: <n>
No-discount cleared: <n>
Stale (>= <days>d): <n>
Total cleared: <n>
Errors: <n>
Output: compare_at_cleanup_<date>.csv
══════════════════════════════════════════════
For format: json, emit:
{
"skill": "compare-at-price-cleanup",
"store": "<domain>",
"dry_run": true,
"variants_inspected": 0,
"cleared_no_discount": 0,
"cleared_stale": 0,
"total_cleared": 0,
"errors": 0,
"output_file": "compare_at_cleanup_<date>.csv"
}
Output Format
CSV file compare_at_cleanup_<YYYY-MM-DD>.csv with columns:
variant_id, product_id, product_title, vendor, sku, price, original_compare_at_price, rule_matched, variant_updated_at, mutation_status
Error Handling
| Error | Cause | Recovery |
|---|---|---|
userErrors in mutation response |
Variant locked or in active subscription contract | Log per-variant error, continue with remaining variants |
THROTTLED |
API rate limit exceeded | Wait 2 seconds, retry up to 3 times |
compareAtPrice already null mid-run |
Another process cleared it concurrently | Skip, count as no-op success |
updatedAt newer than expected |
Concurrent edit during the audit | Re-query single variant before mutation; skip if rule no longer matches |
Best Practices
- Always run with
dry_run: truefirst and review the CSV. There is no bulk undo for compareAtPrice clearing. - Disable
clean_stale(setclean_stale: false) during long planned promotions — your "stale" sale is actually intentional. - Use
collection_idto scope the cleanup to evergreen products and exclude an active sale collection. - After running live, spot-check 5–10 variants in the storefront to confirm strikethrough pricing is gone.
- Schedule a quarterly run as part of catalog hygiene; combine with
seo-metadata-auditandproduct-data-completeness-scorefor an end-of-quarter merchandising sweep.
