# Anthropic - AI agent tools

Use tool definitions for Anthropic to let AI agents read and edit Tiptap documents.

The `@tiptap-pro/ai-toolkit-anthropic` package provides tool definitions you can add to your AI agent built with [Anthropic's JavaScript SDK](https://github.com/anthropics/anthropic-sdk-typescript).

The tool calls generated by the model can then be executed in the client-side using the [`executeTool` method](https://tiptap.dev/docs/content-ai/capabilities/ai-toolkit/api-reference/execute-tool.md).

## Example usage

Install the package.

```bash
npm install @tiptap-pro/ai-toolkit-anthropic
```

Supply the tool definitions to your Anthropic model.

```ts
import Anthropic from '@anthropic-ai/sdk'
import { toolDefinitions } from '@tiptap-pro/ai-toolkit-anthropic'

const anthropic = new Anthropic()

const response = await anthropic.messages.create({
  model: 'claude-sonnet-4-5',
  max_tokens: 2048,
  system: 'You are a helpful assistant that can edit rich text documents.',
  messages: [{ role: 'user', content: 'Help me edit this document' }],
  tools: toolDefinitions(),
})
```

Combine the tool definitions with your custom tools.

```ts
import Anthropic from '@anthropic-ai/sdk'
import { toolDefinitions } from '@tiptap-pro/ai-toolkit-anthropic'

const anthropic = new Anthropic()

const customTools = [
  {
    name: 'get_weather',
    description: 'Get the weather in a location',
    input_schema: {
      type: 'object',
      properties: {
        location: {
          type: 'string',
          description: 'The city and state, e.g. San Francisco, CA',
        },
      },
      required: ['location'],
    },
  },
]

const response = await anthropic.messages.create({
  model: 'claude-sonnet-4-5',
  max_tokens: 1024,
  messages: [{ role: 'user', content: 'What is the weather like and help me edit this document' }],
  tools: [...toolDefinitions(), ...customTools],
})
```
