AI SDK - 工作流程

Workflow Agent是建设耐用AI代理的一门课程,可以维持跨工作流程步骤的状态,调用工具,并优雅地处理中断.

设置

npm i @ai-sdk/workflow zod ai workflow@5

使用量

import { WorkflowAgent } from '@ai-sdk/workflow';
import { z } from 'zod';

const agent = new WorkflowAgent({
  model: 'anthropic/claude-opus-5.5',
  tools: {
    getWeather: {
      description: 'Get weather for a location',
      inputSchema: z.object({ location: z.string() }),
      execute: async ({ location }) => {
        // Fetch weather data
        return { temperature: 72, condition: 'sunny' };
      },
    },
  },
  system: 'You are a helpful weather assistant.',
});

const result = await agent.stream({
  messages: [{ role: 'user', content: 'What is the weather in SF?' }],
  writable: new WritableStream({
    write(chunk) {
      console.log('Chunk:', chunk);
    },
  }),
});

console.log('Final messages:', result.messages);
console.log('Steps:', result.steps);
