# Anthropic Tool Use (Function Calling) ## Overview Tool use lets Claude call functions you define — query databases, hit APIs, read files, do math. Claude decides when to call a tool, you execute it, and feed the result back. This is how you build Claude-powered agents. > **Note:** Anthropic does not offer an embeddings API. For embeddings + vector search, pair Claude with a dedicated embedding model (OpenAI, Cohere, or Voyage). ## Prerequisites - Completed `clade-model-inference` - Understanding of JSON Schema for tool definitions ## Instructions ### Step 1: Define Tools ```typescript import Anthropic from '@claude-ai/sdk'; const client = new Anthropic(); const tools: Anthropic.Tool[] = [ { name: 'get_weather', description: 'Get current weather for a city. Call this when the user asks about weather.', input_schema: { type: 'object', properties: { city: { type: 'string', description: 'City name, e.g. "San Francisco"' }, unit: { type: 'string', enum: ['celsius', 'fahrenheit'], description: 'Temperature unit' }, }, required: ['city'], }, }, ]; ``` ### Step 2: Send Message with Tools ```typescript const response = await client.messages.create({ model: 'claude-sonnet-4-20250514', max_tokens: 1024, tools, messages: [{ role: 'user', content: "What's the weather in San Francisco?" }], }); // Claude responds with stop_reason: 'tool_use' // response.content includes a tool_use block: // { type: 'tool_use', i...
