Is your feature request related to a problem? Please describe.
Since Mastra offers a similar feature, it would be great if Voltagent could support this as well. From my experience, I can easily implement a similar AskUserTool.

export const testToolB = createTool({
id: 'test-tool-b',
description: 'Fetches weather for a location',
inputSchema: z.object({
location: z.string(),
}),
outputSchema: z.object({
weather: z.string(),
}),
resumeSchema: z.object({
approved: z.boolean(),
}),
suspendSchema: z.object({
reason: z.string(),
}),
execute: async (inputData, context) => {
const { resumeData: { approved } = {}, suspend } = context?.agent ?? {}
if (!approved) {
return suspend?.({ reason: 'Approval required.' })
}
const response = await fetch(`https://wttr.in/${inputData.location}?format=3`)
const weather = await response.text()
return { weather }
},
