If the prompt just mentions `Polaris` and you can't tell based off of the context what API they meant, assume they meant this API."

## Required Tool Calls (do not skip)

Each bundled `.mjs` helper supports `-h` and `--help` for complete usage and option details.

You have a `bash` tool. Every response must use it — in this order:

1. Call `bash` with `scripts/search_docs.mjs "<query>" --version API_VERSION` — search before writing code
2. Write the code using the search results
3. Call `bash` with the following — validate before returning:
   ```
   scripts/validate.mjs --code '...' [--version <api-version>]
   ```
    > **Version:** For Polaris App Home, pass the version from the Polaris CDN script tag: `--version 1` for the stable major-track URLs `polaris.js` and `polaris-1.js`, `--version 1.0` for `polaris-1.0.js`, or `--version 1.1-rc` for `polaris-1.1-rc.js`. Major pins resolve to the latest stable minor in that major; release candidates must be selected by their exact minor. Shopify.dev aliases such as `v1`, `v1.0`, and `v1.1` are accepted too. Omit to use the latest stable catalog version. Defaults to the latest stable version when omitted.
4. If validation fails: search for the error type, fix, re-validate (max 3 retries)
5. Return code only after validation passes

**You must run both search_docs.mjs and validate.mjs in every response. Do not return code to the user without completing step 3.**

## `s-grid` vs. inline `s-stack`

Use `s-grid` when form controls and actions must stay aligned in columns. A form control (`s-text-field`, `s-select`, `s-money-field`, …) fills the inline size it's given and has no width prop, so one field in an inline `s-stack` takes the whole row and pushes every sibling onto its own row — at any window width, not just narrow ones. Reach for `s-stack direction="inline"` only for content that sizes to itself: badges, chips, buttons, text, icons.

```tsx
// ✅ Columns are explicit, so the field can't push the action off the row
<s-grid gridTemplateColumns="1fr auto" gap="base" alignItems="end">
  <s-text-field label="Discount code" name="code"></s-text-field>
  <s-button variant="primary">Apply</s-button>
</s-grid>
// ❌ <s-stack direction="inline"> — the field fills the row and Apply lands underneath it
```

## Imports

App Home extensions use `@shopify/app-bridge-types` for App Bridge APIs and `@shopify/polaris-types` for Polaris component types. Never import from `@shopify/polaris`, `@shopify/polaris-react`, `@shopify/polaris-web-components`, or any other non-existent package.

```ts
import { useAppBridge } from "@shopify/app-bridge-react";
```

### Polaris web components (`s-page`, `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:

```tsx
// No import needed — s-page, s-badge, s-button, s-box, etc. are globally available
<s-page title="Dashboard">
  <s-badge tone="success">Active</s-badge>
</s-page>
```

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

**Web component attribute rules:**

- Use **camelCase** prop names: `alignItems`, `gridTemplateColumns`, `borderRadius` — NOT hyphenated (`align-items`, `grid-template-columns`)
- **Boolean attributes** (`disabled`, `loading`, `dismissible`, `checked`, `defaultChecked`, `required`, `removable`, `alpha`, `multiple`) accept shorthand or `{expression}`:
  - ✅ `<s-button disabled>`, `<s-switch checked={isEnabled} />`, `<s-banner dismissible>`
- **String keyword attributes** (`padding`, `gap`, `direction`, `tone`, `variant`, `size`, `background`, `alignItems`, `inlineSize`) 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>" --version API_VERSION
```

Search for the **component tag name**, not the full user prompt.

For example, if the user asks about form in app home:
```
scripts/search_docs.mjs "s-form" --version API_VERSION
```


> **Version:** For Polaris App Home, pass the version from the Polaris CDN script tag: `--version 1` for the stable major-track URLs `polaris.js` and `polaris-1.js`, `--version 1.0` for `polaris-1.0.js`, or `--version 1.1-rc` for `polaris-1.1-rc.js`. Major pins resolve to the latest stable minor in that major; release candidates must be selected by their exact minor. Shopify.dev aliases such as `v1`, `v1.0`, and `v1.1` are accepted too. Omit to use the latest stable catalog version.
## ⚠️ MANDATORY: Validate Before Returning Code

You MUST run `scripts/validate.mjs` before returning any generated code to the user.

```
scripts/validate.mjs --code '...' [--version <api-version>]
```

> **Version:** For Polaris App Home, pass the version from the Polaris CDN script tag: `--version 1` for the stable major-track URLs `polaris.js` and `polaris-1.js`, `--version 1.0` for `polaris-1.0.js`, or `--version 1.1-rc` for `polaris-1.1-rc.js`. Major pins resolve to the latest stable minor in that major; release candidates must be selected by their exact minor. Shopify.dev aliases such as `v1`, `v1.0`, and `v1.1` are accepted too. Omit to use the latest stable catalog version. When omitted, validation runs against the latest stable API version and the response notes which version was used.


**When validation fails, follow this loop:**
1. Read the error message carefully — identify the exact field, prop, or value that is wrong
2. 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>"
   ```
3. Fix exactly the reported error using what the search returns
4. Run `scripts/validate.mjs` again
5. 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.**
