What it does

Shopify Admin Variant Option Normalizer is an agent skill from 40RTY-ai/shopify-admin-skills. Detects inconsistent variant option naming (Sm vs Small vs S) and bulk-corrects to a standard set.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI

It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.

Example prompts

  • “Use the shopify-admin-variant-option-normalizer skill to detect inconsistent variant option naming (Sm vs Small vs S) and bulk-corrects to a…”
  • “/shopify-admin-variant-option-normalizer”

Requirements

  • Compatibility (from SKILL.md): Claude Code, Cursor, Codex, Gemini CLI

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. OPERATION: products — query
  2. Match variant option values against mapping keys — collect variants needing update
  3. OPERATION: productVariantsBulkUpdate — mutation

What it can do on your machine

Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • shopify

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code, Cursor, Codex, Gemini CLI

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Admin Variant Option Normalizer loads about 1.5k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 398 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Purpose

Scans product variants for inconsistent option values (e.g., "Sm", "Small", "small", "S" all meaning the same size) and bulk-updates them to a canonical set you define. Inconsistent option naming breaks size filters, causes customer confusion, and prevents search apps from grouping variants correctly.

Prerequisites

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

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
option_namestringyes—Option to normalize (e.g., Size, Color)
mappingobjectyes—Map of non-standard → canonical values (e.g., {"Sm": "S", "small": "S", "Sml": "S"})
filterstringno—Optional product filter (e.g., tag:apparel)
dry_runboolnotruePreview changes without executing mutations
formatstringnohumanOutput format: human or json

Safety

⚠️ productVariantsBulkUpdate modifies variant option values. Option value changes affect how the variant appears to customers in the storefront and may break existing cart links or saved wishlists. Run with dry_run: true to review all affected variants before committing.

Workflow Steps

  1. OPERATION: products — query Inputs: query: <filter> (or all products if no filter), first: 250, select options, variants { selectedOptions }, pagination cursor Expected output: Products with variant option values; paginate until hasNextPage: false

  2. Match variant option values against mapping keys — collect variants needing update

  3. OPERATION: productVariantsBulkUpdate — mutation Inputs: productId, array of variants { id, options: [<normalized_value>] } for affected variants Expected output: productVariants { id, selectedOptions }, userErrors

Session Tracking

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

On start, emit:

          → 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:

}

Output Format

CSV file option_normalizer_<YYYY-MM-DD>.csv with columns: product_id, product_title, variant_id, sku, option_name, old_value, new_value

Error Handling

ErrorCauseRecovery
THROTTLEDAPI rate limit exceededWait 2 seconds, retry up to 3 times
userErrors on bulk updateOption value conflict within productLog error, skip product, continue
No matching variantsMapping keys not found in catalogExit with 0 matches, review mapping

Best Practices

  • Build the mapping by first running with dry_run: true and reviewing the detected option values — you may discover more variants than expected.
  • Normalize one option_name at a time (Size, then Color separately) to keep the mapping manageable and reduce error risk.
  • After normalizing, verify that automated collection rules based on option values still match the intended products.
