// Update with plain metadata
const updated = await dataset.update({
  name: 'Updated QA pairs',
  description: 'Revised evaluation set',
})

// Update with Zod schema (auto-converted to JSON Schema)
const updated2 = await dataset.update({
  inputSchema: z.object({
    question: z.string(),
    context: z.string().optional(),
  }),
})
