+description: 'Generate TypeScript definitions from PHP DTOs and Enums'
+---
+
+You are an expert TypeScript developer. Your task is to generate TypeScript definitions from the PHP codebase in this repository.
+
+## Goal
+Generate two files in the repository root:
+1. `enums.ts`: Contains all Enum definitions.
+2. `types.ts`: Contains all DTO (Data Transfer Object) definitions.
+
+## Source Files
+- **DTOs:** Scan all PHP files in `src/**/DTO/*.php`.
+- **Enums:** Scan all PHP files in `src/**/Enums/*.php`.
+
+## Exclusions
+**DO NOT** generate types for the following, even if they are in a DTO or Enum directory:
+- HTTP transport classes (e.g., `Request`, `Response`, `HttpMethodEnum`). **EXCEPTION:** `RequestOptions` MUST be included.
+- Model requirement classes (e.g., `ModelRequirements`, `RequiredOption`).
+- `ProviderModelsMetadata`.
+
+## Rules for `enums.ts`
+1. **Header:** The file MUST start with the following comment:
+   ```typescript
+   /**
+    * TypeScript definitions for PHP AI Client SDK Enums.
+    *
+    * This file is auto-generated based on the PHP Enum classes. DO NOT MODIFY IT MANUALLY.
+    */
+   ```
+2. **Format:** Export a `const` object with `as const` and a corresponding `type` definition.
+3. **Naming:**
+   - The `const` object name must match the PHP Enum class name (remove `Enum` suffix if it exists, e.g., `FileTypeEnum` -> `FileType`).
+   - Keys in the `const` object must be **UPPERCASE**.
+   - Values must be the actual string/int values from the PHP Enum.
+4. **Type Definition:** The type must be derived from the `const` object using `typeof EnumName[keyof typeof EnumName]`.
+
+**Example:**
+```typescript
+export const FileType = {
+    INLINE: 'inline',
+    REMOTE: 'remote',
+} as const;
+export type FileType = typeof FileType[keyof typeof FileType];
+```
+
+## Rules for `types.ts`
+1. **Header:** The file MUST start with the following comment:
+   ```typescript
+   /**
+    * TypeScript definitions for PHP AI Client SDK DTOs.
+    *
+    * This file is auto-generated based on the PHP DTO classes. DO NOT MODIFY IT MANUALLY.
+    */
+   ```
+2. **Imports:** Import all necessary Enum types from `./enums`.
+3. **Format:** Use `type` aliases. **Do not use `interface`.**
+4. **Naming:** Match the PHP DTO class name.
+5. **Properties:**
+   - Use camelCase for property names (matching the keys in the PHP `toArray()` method).
+   - **Nullable Types:** If a PHP property is nullable (`?string` or `string|null`), make the TypeScript property **optional** (`prop?: string`). **Do not use `string | null`.**
+6. **Strict Typing:**
+   - **NEVER use `any`.**
+   - Use `unknown` for mixed/unspecified values.
+   - Use `Record<string, unknown>` for associative arrays or "additional data".
+7. **Arrays:** Use `Type[]` syntax.
+
+**Example:**
+```typescript
+import type { FileType } from './enums';
+
+export type File = {
+    fileType: FileType;
+    mimeType: string;
+    url?: string;       // PHP: ?string
+    base64Data?: string;
+    metadata?: Record<string, unknown>; // PHP: array
+};
+```
+
+## Execution
+Read the PHP files, analyze their structure, and generate the TypeScript files according to these strict rules.
