@polymind-inc/agent-framework-anthropic

Constituent package. The supported way to use the Agent Framework is the main @polymind-inc/agent-framework package, which re-exports everything here under @polymind-inc/agent-framework/anthropic and pins this package to its exact version. Installing this package directly works and resolves to the same modules, but examples and documentation import through the main package.

Anthropic provider for the Agent Framework: AnthropicChatClient implements the ChatClient interface from @polymind-inc/agent-framework-core on top of the official @anthropic-ai/sdk Messages API, including streaming, extended thinking, structured output and remote MCP servers. Pass an AnthropicBedrock, AnthropicVertex or AnthropicFoundry client to reach Claude through those gateways — the wire format is identical.

npm install @polymind-inc/agent-framework-core @polymind-inc/agent-framework-anthropic

import { Agent } from '@polymind-inc/agent-framework-core';
import { AnthropicChatClient } from '@polymind-inc/agent-framework-anthropic';

const agent = new Agent({
  client: new AnthropicChatClient({ model: 'claude-sonnet-4-5' }), // reads ANTHROPIC_API_KEY
  instructions: 'You are a helpful assistant.',
});

const response = await agent.run('Summarize the Messages API in one sentence.');
console.log(response.text);
