Agent quickstart

This guide creates one discovered agent.

Install Agent

pnpm add @vitehub/agent ai

Register the integration

vite.config.ts

import { hubAgent } from '@vitehub/agent/vite'
import { nitro } from 'nitro/vite'
import { defineConfig } from 'vite'

export default defineConfig({
  plugins: [
    hubAgent(),
    nitro(),
  ],
})

Define the agent

server/agents/triager.ts

import { defineAgent, type AgentToolDefinition } from '@vitehub/agent'
import { gateway } from '@ai-sdk/gateway'

const classifyTicket: AgentToolDefinition<{ message: string }, { queue: string; priority: string }> = {
  name: 'classifyTicket',
  description: 'Classify a support request before queue handoff.',
  execute: ({ message }) => ({
    queue: /refund|invoice|payment/i.test(message) ? 'billing' : 'product',
    priority: /urgent|down|broken/i.test(message) ? 'urgent' : 'normal',
  }),
}

export default defineAgent({
  capabilities: [{
    id: 'support-triage',
    tools: { classifyTicket },
  }],
  description: 'Triage support requests and prepare a queue handoff.',
  instructions: 'Classify support requests and prepare queue handoff.',
  model: gateway('openai/gpt-5.1-mini'),
  adapter: 'ai-sdk',
})

Call it from Chat

@vitehub/agent/chat can route direct messages to a discovered agent by name.

server/chat.ts

import { defineChat } from '@vitehub/agent/chat'

export default defineChat({
  adapters,
  agent: 'triager',
  state,
  userName: 'Support Bot',
})

Verify

The agent is available to other ViteHub packages through the generated registry. If you also enable routes, the generated route can call the same discovered agent.
