At a glance

Reference for Shopify work: Liquid templates, OS 2.0 themes, Admin and Storefront GraphQL APIs, apps, Functions and Hydrogen, on API version 2026-01.

  • Writing or debugging .liquid templates in a Shopify theme
  • SKILL.md covers Quick Reference, Choose Your Path, Deprecation Notices and Liquid Essentials, plus 2 more sections
  • Calls shopify and npm
  • Building or customizing an OS 2.0 theme with sections and blocks

What it does

This skill is a Shopify reference split into task-based files. A quick-reference table gives the API version (2026-01), the GraphQL Admin and Storefront endpoints, the Ajax cart paths and the CLI commands for installing, running theme and app development, and deploying.

A Choose Your Path section sends the agent to the file that matches the job: Liquid syntax, filters and objects; OS 2.0 theme architecture with sections, blocks and JSON templates; the Admin API (GraphQL first, REST as legacy, plus OAuth, webhooks and rate limiting); the Storefront and Ajax APIs; app development with Shopify CLI, extensions, Polaris Web Components and App Bridge; and Shopify Functions, which replace Scripts. Further files cover Hydrogen headless storefronts, debugging and performance. It applies to Shopify only.

When your agent uses it

  • Writing or debugging .liquid templates in a Shopify theme
  • Building or customizing an OS 2.0 theme with sections and blocks
  • Writing GraphQL queries against the Admin or Storefront API
  • Moving custom logic from Scripts to Shopify Functions
  • Building a headless storefront with Hydrogen

Example prompts

  • “Fix the Liquid error on our product page template that breaks the variant picker.”
  • “Write a Storefront API query that lists the products in a collection with their prices.”
  • “Convert our old Shopify Script discount rule into a Shopify Function.”

Requirements

  • Shopify CLI for theme and app commands

What it can do on your machine

Read from SKILL.md and the folder at commit 6df68d5. 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
    • npm

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

  • Network

    Links to these hosts (documentation or services it may open):

    • shopify.dev

    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.

Context cost

Shopify Developer Reference loads about 1.9k tokens when it runs, and up to ~39k if it reads all its reference files. Until then it costs about 145 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~39k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 384 words (~1,872 tokens).

“Comprehensive reference for professional Shopify development - API version 2026-01.”
