使用ProviderTool和AI Gateway的例子

provider_tools.ts

import 'dotenv/config';
import { streamText } from 'ai';
import { anthropicTools } from '@ai-sdk/anthropic/internal';

const result = await streamText({
  model: 'anthropic/claude-sonnet-4.5',
  tools: {
    codeExecution: anthropicTools.codeExecution_20250522(),
  },
  messages: [{ role: 'user', content: 'Run: print(1+1)' }],
});

for await (const textPart of result.textStream) {
  process.stdout.write(textPart);
}
console.log();
