What it does

Shopify Admin Return Fraud Detector is an agent skill from 40RTY-ai/shopify-admin-skills. Read-only: identifies customers with abnormal return behavior — high return rate, wardrobing patterns, or serial returner profiles — for manual review.

Its SKILL.md is about 1.9k 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

  • “/shopify-admin-return-fraud-detector”

Requirements

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

Workflow steps

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

  1. OPERATION: orders — query
  2. OPERATION: returns — query
  3. OPERATION: customers — query
  4. Per customer compute total_orders, total_returns, return_rate, wardrobing_count (returns within wardrobing_window_days of delivery where Σ…

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 Return Fraud Detector loads about 1.9k tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 520 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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

Surfaces customers whose return behavior deviates statistically from the store baseline so support and ops can review them before approving the next return. Three patterns are detected: (1) high return rate (≥40% of orders returned), (2) wardrobing — full-order returns shortly after delivery, (3) serial returners — many returns over time. Read-only. Output is a candidate list, not an automatic block list.

Prerequisites

  • Authenticated Shopify CLI session: shopify store auth --store <domain> --scopes read_orders,read_returns,read_customers
  • API scopes: read_orders, read_returns, read_customers

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
formatstringnohumanOutput format: human or json
days_backintegerno365Lookback window for orders and returns
min_ordersintegerno3Minimum lifetime orders for a customer to be evaluated (avoid penalizing one-off accidents)
return_rate_thresholdfloatno0.40Fraction of orders returned to flag as high (default 40%)
wardrobing_window_daysintegerno14Window between delivery and return-initiated to flag as wardrobing
serial_thresholdintegerno5Minimum total returns to flag as serial returner

Safety

ℹ️ Read-only skill — no mutations are executed. Output flags candidates for human review only — never block or restrict customers automatically. False positives are common (genuine size issues, address-correction returns, etc.); investigate before action.

Workflow Steps

  1. OPERATION: orders — query Inputs: query: "created_at:>='<NOW - days_back days>'", first: 250, select id, customer { id }, processedAt, fulfillments { deliveredAt }, totalPriceSet, lineItems { quantity }, paginate Expected output: All orders in window grouped by customer.id

  2. OPERATION: returns — query Inputs: Same date filter, first: 250, select id, createdAt, order { customer { id } }, returnLineItems { quantity }, totalQuantity Expected output: All returns in window joined to customer

  3. OPERATION: customers — query Inputs: For flagged candidates only: query: "id:<ids>", select identity fields and tags Expected output: Contact data for the candidates list

  4. Per customer compute total_orders, total_returns, return_rate, wardrobing_count (returns within wardrobing_window_days of delivery where Σ return qty ≥ Σ order qty). Flag rules: high_return_rate (orders ≥ min_orders AND rate ≥ return_rate_threshold), wardrobing (count ≥ 2), serial_returner (returns ≥ serial_threshold).

Best Practices

  • Treat output as a review queue, never an automatic action — manually validate before tagging or restricting any account.
  • Tune return_rate_threshold to your category baseline. Apparel stores run 20–30% return rates; flagging at 40% picks outliers. For electronics or homewares, drop to 15–20%.
  • Cross-reference with return-reason-analysis — if returns concentrate on one product, the issue may be product quality, not abuse.
  • Pair with customer-merge candidates from duplicate-customer-finder — fraudsters often create duplicate accounts to dodge return-rate flags.
  • Run quarterly with a 12-month window for stable signal; monthly runs produce noisy flags from new customers with one return.
