Imports

Use the Preact entry point:

import "@shopify/ui-extensions/preact";

import { render } from "preact";

Polaris web components ( s-banner , 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-banner, s-badge, s-button, etc. are globally available

<s-banner tone="info">Welcome back</s-banner>

<s-badge tone="success">Order placed</s-badge>

When the user asks for Polaris web components (e.g. s-banner, s-badge, s-button, s-text), use the web component tag syntax above.

Web component attribute rules:

Use camelCase attribute names: alignItems, paddingBlock, borderRadius — NOT kebab-case (align-items, padding-block)

Boolean attributes (disabled, loading, dismissible, checked, defaultChecked, required) accept shorthand or {expression}:

✅ <s-checkbox checked={isSelected} />, <s-button disabled>, <s-banner dismissible>

String keyword attributes (padding, gap, direction, tone, variant, size, background, alignItems) 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 TypeScript

⚠️ MANDATORY: Search Before Writing Code

Search 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 customer account card:

scripts/search_docs.mjs "s-card customer-account" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION

⚠️ MANDATORY: Validate Before Returning Code

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 --target <extension-target>

**--target is required for customer-account extensions.** Pass the extension target this code runs in (e.g. customer-account.order-status.block.render). If you don't know which target applies, run scripts/search_docs.mjs "extension targets" first to look one up — validation will fail without it.

(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:

Read the error message carefully — identify the exact field, prop, or value that is wrong

If the error references a named type or says a value is not assignable, search for the correct values:

scripts/search_docs.mjs "<type or prop name>"

Fix exactly the reported error using what the search returns

Run scripts/validate.mjs again

Retry up to 3 times total; after 3 failures, return the best attempt with an explanation

Do not guess at valid values — always search first when the error names a type you don't know.

Privacy notice: scripts/search_docs.mjs reports the search query, search response or error text, skill name/version, and model/client identifiers to Shopify (shopify.dev/mcp/usage) to help improve these tools. Set OPT_OUT_INSTRUMENTATION=true in your environment to opt out.

Privacy notice: scripts/validate.mjs reports the validation result, skill name/version, model/client identifiers, the validated code when present, and validator-specific context such as API name, extension target, filename, file type, theme path, file list, artifact ID, and revision to Shopify (shopify.dev/mcp/usage) to help improve these tools. Set OPT_OUT_INSTRUMENTATION=true in your environment to opt out.
