Required Tool Calls (do not skip)

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

1. Call bash with scripts/search_docs.mjs "<query>" — search before writing code
2. Write the code using the search results
3. Call bash 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.)
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.

Hydrogen Cookbook - Ready-to-Use Recipes

Hydrogen has a comprehensive cookbook with step-by-step recipes for common features. Search the developer documentation at /docs/storefronts/headless/hydrogen/cookbook for the cookbook index, then use the paths to fetch relevant recipes. Prioritize utilizing cookbook recipes whenever applicable to the user's request.

🚨 CRITICAL ERROR PREVENTION 🚨

NEVER use api:"storefront" for these components - they are REACT COMPONENTS:

• Image, Video, ExternalVideo, MediaFile, Money - NOT GraphQL types!
• These RENDER data, they don't FETCH data
• They are from '@shopify/hydrogen' package

MANDATORY REQUIREMENTS:

1. ALWAYS use api:"hydrogen" for ALL components below
2. ALWAYS generate complete JSX code examples
3. If asked about "Media" or "MediaFile" - use api:"hydrogen" NOT api:"storefront"!

REMEMBER:

• These components CONSUME data from Storefront API
• They are NOT the data types themselves
• They are React UI components that render HTML

/**
Useful to flatten the type output to improve type hints shown in editors. And also to transform an interface into a type to aide with assignability.

@example

import type {Simplify} from 'type-fest';

type PositionProps = { top: number; left: number; };

type SizeProps = { width: number; height: number; };

// In your editor, hovering over Props will show a flattened object with all the properties. type Props = Simplify<PositionProps & SizeProps>;

Sometimes it is desired to pass a value as a function argument that has a different type. At first inspection it may seem assignable, and then you discover it is not because the `value`'s type definition was defined as an interface. In the following example, `fn` requires an argument of type `Record<string, unknown>`. If the value is defined as a literal, then it is assignable. And if the `value` is defined as type using the `Simplify` utility the value is assignable.  But if the `value` is defined as an interface, it is not assignable because the interface is not sealed and elsewhere a non-string property could be added to the interface.

If the type definition must be an interface (perhaps it was defined in a third-party npm package), then the `value` can be defined as `const value: Simplify<SomeInterface> = ...`. Then `value` will be assignable to the `fn` argument.  Or the `value` can be cast as `Simplify<SomeInterface>` if you can't re-declare the `value`.

@example

import type {Simplify} from 'type-fest';

interface SomeInterface { foo: number; bar?: string; baz: number | undefined; }

type SomeType = { foo: number; bar?: string; baz: number | undefined; };

const literal = {foo: 123, bar: 'hello', baz: 456}; const someType: SomeType = literal; const someInterface: SomeInterface = literal;

function fn(object: Record<string, unknown>): void {}

fn(literal); // Good: literal object type is sealed fn(someType); // Good: type is sealed fn(someInterface); // Error: Index signature for type 'string' is missing in type 'someInterface'. Because interface can be re-opened fn(someInterface as Simplify); // Good: transform an interface into a type

type Simplify<T> = {
	[KeyType in keyof T]: T[KeyType];
} & {};
/**
Omit any index signatures from the given object type, leaving only explicitly defined properties.

This is the counterpart of `PickIndexSignature`.

Use-cases:
- Remove overly permissive signatures from third-party types.

This type was taken from this [StackOverflow answer](https://stackoverflow.com/a/68261113/420747).

It relies on the fact that an empty object (`{}`) is assignable to an object with just an index signature, like `Record<string, unknown>`, but not to an object with explicitly defined keys, like `Record<'foo' | 'bar', unknown>`.

(The actual value type, `unknown`, is irrelevant and could be any type. Only the key type matters.)

const indexed: Record<string, unknown> = {}; // Allowed

const keyed: Record<'foo', unknown> = {}; // Error // => TS2739: Type '{}' is missing the following properties from type 'Record<"foo" | "bar", unknown>': foo, bar

Instead of causing a type error like the above, you can also use a [conditional type](https://www.typescriptlang.org/docs/handbook/2/conditional-types.html) to test whether a type is assignable to another:

type Indexed = {} extends Record<string, unknown> ? '✅ {} is assignable to Record<string, unknown>' : '❌ {} is NOT assignable to Record<string, unknown>'; // => '✅ {} is assignable to Record<string, unknown>'

type Keyed = {} extends Record<'foo' | 'bar', unknown> ? "✅ {} is assignable to Record<'foo' | 'bar', unknown>" : "❌ {} is NOT assignable to Record<'foo' | 'bar', unknown>"; // => "❌ {} is NOT assignable to Record<'foo' | 'bar', unknown>"

Using a [mapped type](https://www.typescriptlang.org/docs/handbook/2/mapped-types.html#further-exploration), you can then check for each `KeyType` of `ObjectType`...

import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature = { [KeyType in keyof ObjectType // Map each key of ObjectType... ]: ObjectType[KeyType]; // ...to its original value, i.e. OmitIndexSignature<Foo> == Foo. };

...whether an empty object (`{}`) would be assignable to an object with that `KeyType` (`Record<KeyType, unknown>`)...

import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature = { [KeyType in keyof ObjectType // Is {} assignable to Record<KeyType, unknown>? as {} extends Record<KeyType, unknown> ? ... // ✅ {} is assignable to Record<KeyType, unknown> : ... // ❌ {} is NOT assignable to Record<KeyType, unknown> ]: ObjectType[KeyType]; };

If `{}` is assignable, it means that `KeyType` is an index signature and we want to remove it. If it is not assignable, `KeyType` is a "real" key and we want to keep it.

@example

import type {OmitIndexSignature} from 'type-fest';

interface Example { // These index signatures will be removed. [x: string]: any [x: number]: any [x: symbol]: any [x: head-${string}]: string [x: ${string}-tail]: string [x: head-${string}-tail]: string [x: ${bigint}]: string [x: embedded-${number}]: string

	b: string;
