Overview

Shopify Custom Data Skill is an official Shopify agent skill from the Shopify/agent-skills collection. It gives coding agents (Claude Code, Cursor, and compatible tools) up-to-date instructions, documentation search helpers, and validation context for Shopify development.

Use Metafields and Metaobjects to model and store custom data for your app. Metafields extend built-in Shopify data types like products or customers, Metaobjects are custom data types that can be used to store bespoke data structures. Metafield and Metaobject definitions provide a schema and configuration for values to follow.

Install it into your agent environment with:

npx skills add https://github.com/Shopify/agent-skills --skill shopify-custom-data

Source: https://github.com/Shopify/agent-skills/tree/main/shopify-custom-data

Key Features

  • Shopify-verified context: Instructions are generated for Shopify's current APIs and verified against upstream docs.
  • Docs-aware guidance: Skills steer the agent to search shopify.dev examples instead of relying only on training data.
  • Schema / component awareness: Many skills ship offline references and validators for GraphQL schemas or UI component libraries.
  • Composable installs: Install only the surfaces you need (--skill shopify-custom-data) without pulling the whole monorepo into every session.
  • Open source: Free to use under the repository's open-source license on GitHub.

How to Use

  1. Use a Skill-compatible agent such as Claude Code, Cursor, or Codex.
  2. Install from the terminal (Node.js required):
npx skills add https://github.com/Shopify/agent-skills --skill shopify-custom-data

Or paste the install prompt from this tool page into your agent and ask it to install for you. 3. Restart / reload the agent so the new Skill is loaded. 4. Invoke the Skill with its slash commands or by asking the agent to run the workflow described in Overview / Key Features. 5. Review outputs before publishing — treat model-generated copy, images, and data as drafts.

FAQ

How do I install this skill?

Run npx skills add https://github.com/Shopify/agent-skills --skill shopify-custom-data in a terminal where the skills CLI is available, then open your agent (Claude Code / Cursor) so it can load the skill.

Is this an official Shopify product?

The skills are published by Shopify on GitHub as agent instruction packs for developers. They help agents work with Shopify APIs; they are not a merchant-facing SaaS app.

Do I need a paid Shopify plan?

You can install the skill for free. Building and testing against live Shopify APIs typically requires a Partner account and a development store.
