Let's break this down step by step:

1. We need to add a new method to the `ExampleClient` class for the GET /users/{id} endpoint
2. The method needs to:
   - Accept the `id` parameter as a string
   - Use the existing `fetch` method
   - Handle potential errors
   - Return a Promise with the response
3. Since there's no response schema defined in the OpenAPI spec, we'll use `any` as the return type
4. We'll add proper JSDoc comments with the route information
5. We'll use the existing error handling infrastructure

Here's the code to add:

```typescript:client.ts
// ... existing code ...

export class ExampleClient {
  // ... existing methods ...

  /**
   * GET /users/{id}
   * @tags example-tag
   * @param id - The user ID
   * @returns Promise<any>
   */
  async getUserById(id: string): Promise<any> {
    try {
      const response = await this.fetch({
        method: 'GET',
        path: `/users/${encodeURIComponent(id)}`
      });

      if (!response.ok) {
        const errorData = await response.json().catch(() => ({}));
        throw new ExampleError('Failed to fetch user', {
          status: response.status,
          data: errorData
        });
      }

      return response.json();
    } catch (error) {
      if (error instanceof ExampleError) {
        throw error;
      }
      throw new ExampleError('Network error', { status: 500 });
    }
  }
}

// ... rest of existing code ...
```
