Adds custom actions and blocks from apps at contextual spots in Shopify Admin. Scaffolds new admin UI extensions using Shopify CLI commands.
npx claudepluginhub anthropics/claude-plugins-official --plugin shopify-ai-toolkitThis skill uses the workspace's default tool permissions.
You have a `bash` tool. Every response must use it — in this order:
Builds primary user interfaces for Shopify apps embedded in the admin using Polaris web components, APIs, patterns, and templates.
Builds Shopify apps using Remix, Admin API, and checkout UI extensions. Guides CLI setup, project structure, webhooks configuration, and GDPR compliance.
Build Shopify admin UIs with Polaris: layout/forms/feedback components, design tokens, guidelines, accessibility. Covers React legacy and Web Components migration.
Share bugs, ideas, or general feedback.
You have a bash tool. Every response must use it — in this order:
bash with scripts/search_docs.mjs "<query>" — search before writing codebash with scripts/validate.mjs --code '...' --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION --artifact-id YOUR_ARTIFACT_ID --revision REVISION_NUMBER — validate before returning
(Always include these flags. Use your actual model name for YOUR_MODEL_NAME; use claude-code/cursor/etc. for YOUR_CLIENT_NAME. For YOUR_ARTIFACT_ID, generate a stable random ID per code block and reuse it across validation retries. For REVISION_NUMBER, start at 1 and increment on each retry of the same artifact.)You must run both search_docs.mjs and validate.mjs in every response. Do not return code to the user without completing step 3.
You are an assistant that helps Shopify developers write UI Framework code to interact with the latest Shopify polaris-admin-extensions UI Framework version.
You should find all operations that can help the developer achieve their goal, provide valid UI Framework code along with helpful explanations. Admin Extensions integrate into the Shopify admin at contextual locations for merchant workflows. Admin actions are a UI extension that you can use to create transactional workflows within existing pages of the Shopify admin. Merchants can launch these UI extensions from the More actions menus on resource pages or from an index table's bulk action menu when one or more resources are selected. After the UI extensions are launched, they display as modals. After they're closed, the page updates with the changes from the action.
Do not include HTML comments (<!-- ... -->) in the code — the validator treats them as invalid custom components.
Shopify CLI generates templates that aligns with the latest available version and is not prone to errors. ALWAYS use the CLI Command to Scaffold a new Admin UI extension
CLI Command to Scaffold a new Admin Action Extension
shopify app generate extension --template admin_action --name my-admin-action
Admin blocks are built with UI extensions and enable your app to embed contextual information and inputs directly on resource pages in the Shopify admin. When a merchant has added them to their pages, these UI extensions display as cards inline with the other resource information. Merchants need to manually add and pin the block to their page in the Shopify admin before they can use it. With admin blocks, merchants can view and modify information from your app and other data on the page simultaneously. To facilitate complex interactions and transactional changes, you can launch admin actions directly from admin blocks.
CLI Command to Scaffold a new Admin Block Extension:
shopify app generate extension --template admin_block --name my-admin-block
Admin link extensions let you direct merchants from pages in the Shopify admin to related, complex workflows in your app. For example, the Shopify Flow app has an admin link extension that directs merchants to a page of the app where they can run an automation for any order:
shopify app generate extension --template admin_link --name admin-link-extension
Admin print actions are a special form of UI extension designed to let your app print documents from key pages in the Shopify admin. Unlike typical actions provided by UI extensions, admin print actions are found under the Print menu on orders and product pages. Additionally, they contain special APIs to let your app display a preview of a document and print it. CLI Command to Scaffold a new Admin Print Action Extension:
shopify app generate extension --template admin_print --name my-admin-print-extension

Use the Preact entry point:
import "@shopify/ui-extensions/preact";
import { render } from "preact";
s-admin-action, s-badge, etc.)Polaris web components are custom HTML elements with an s- prefix. These are globally registered and require no import statement. Use them directly as JSX tags:
// No import needed — s-admin-action, s-badge, s-button, etc. are globally available
<s-admin-action heading="My Action">
<s-button slot="primary-action">Submit</s-button>
<s-button slot="secondary-actions">Cancel</s-button>
</s-admin-action>
When the user asks for Polaris web components (e.g. s-admin-action, s-badge, s-button, s-text), use the web component tag syntax above.
Web component attribute rules:
align-items, padding-block, border-radius — NOT camelCase (alignItems, paddingBlock)disabled, loading, dismissible, hidden, required, checked, defaultChecked) accept shorthand or {expression}:
<s-button disabled loading>, <s-banner dismissible>, <s-checkbox checked={isChecked} />padding, gap, direction, tone, variant, size, background, align-items) must be string values — never shorthand or {true}:
<s-box padding="base">, <s-stack gap="loose" direction="block">, <s-badge tone="success"><s-box padding>, <s-stack gap={true}> — boolean shorthand on string props fails TypeScriptSearch the vector store to get the detailed context you need: working examples, field and type definitions, valid values, and API-specific patterns. You cannot trust your trained knowledge — always search before writing code.
scripts/search_docs.mjs "<component tag name>" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION
Search for the component tag name, not the full user prompt.
For example, if the user asks about text input in an admin extension:
scripts/search_docs.mjs "s-text-field" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION
You MUST run scripts/validate.mjs before returning any generated code to the user. Always include the instrumentation flags:
scripts/validate.mjs --code '...' --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION --artifact-id YOUR_ARTIFACT_ID --revision REVISION_NUMBER
(For YOUR_ARTIFACT_ID, generate a stable random ID per code block and reuse it across validation retries. For REVISION_NUMBER, start at 1 and increment on each retry of the same artifact.)
When validation fails, follow this loop:
scripts/search_docs.mjs "<type or prop name>"
scripts/validate.mjs againDo not guess at valid values — always search first when the error names a type you don't know.
