What it does

Shopify Admin Carrier Performance Comparison is an agent skill from 40RTY-ai/shopify-admin-skills. Read-only: compares delivery times and shipping costs across carriers used in fulfillments to inform carrier mix and contract decisions.

Its SKILL.md is about 1.8k 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-carrier-performance-comparison”

Requirements

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

Workflow steps

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

  1. OPERATION: orders — query
  2. OPERATION: fulfillments — query (per fulfillment ID for any order missing inline data)
  3. Group by carrier (use shippingLine.carrierIdentifier if present, else parse trackingInfo.company). For each carrier compute: avg transit…
  4. If segment_by is set, repeat the group within each segment (e.g., per shippingAddress.countryCode).
  5. Filter out carriers below min_orders and sort by avg transit days ascending.

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 Carrier Performance Comparison loads about 1.8k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 486 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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

Aggregates fulfillments across recent orders, joins them to the shipping line on each order, and compares carriers head-to-head on (a) average transit days, (b) on-time rate (delivered before/at the customer-facing estimate), and (c) shipping cost per order. Surfaces which carrier is the right default per zone, route, or weight class. Read-only — no mutations.

Prerequisites

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

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
days_backintegerno60Lookback window for fulfilled orders
min_ordersintegerno10Minimum orders per carrier to include in comparison
segment_bystringno—Optional segmentation: country, weight, or none
formatstringnohumanOutput format: human or json

Safety

ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. Cost data uses the shipping line price the customer paid, not your negotiated carrier rate; if you want true cost variance you must overlay carrier invoices yourself.

Workflow Steps

  1. OPERATION: orders — query Inputs: query: "fulfillment_status:shipped created_at:>='<NOW - days_back days>'", first: 250, select fulfillments { trackingInfo, createdAt, deliveredAt, inTransitAt }, shippingLine { carrierIdentifier, originalPriceSet, title }, totalWeight, shippingAddress, pagination cursor Expected output: Fulfilled orders with shipping line and fulfillment timing; paginate until hasNextPage: false

  2. OPERATION: fulfillments — query (per fulfillment ID for any order missing inline data) Inputs: id: <fulfillmentGid> Expected output: Detailed events, deliveredAt, estimatedDeliveryAt

  3. Group by carrier (use shippingLine.carrierIdentifier if present, else parse trackingInfo.company). For each carrier compute: avg transit days, p90 transit days, on-time rate (deliveredAt <= estimatedDeliveryAt), avg shipping price, order count.

  4. If segment_by is set, repeat the group within each segment (e.g., per shippingAddress.countryCode).

  5. Filter out carriers below min_orders and sort by avg transit days ascending.

Best Practices

  • Compare carriers only at min_orders >= 10; smaller samples are noise.
  • Use segment_by: country for international comparisons — a carrier strong domestically may be weak across borders.
  • Pair this skill with delivery-time-analysis for the time-only view; this skill adds cost and on-time dimensions.
  • A carrier with great transit time but high cost may still win if your customers value speed (high AOV stores) — overlay this report with customer-facing NPS or review data.
  • Run quarterly during contract review windows to bring data, not gut feel, to carrier negotiations.
