# Anthropic Core Workflow B → Tool Use

## Overview
This skill redirects to `clade-embeddings-search` which covers tool use (function calling), the agentic tool loop, and building Claude-powered agents.

## Prerequisites
- Completed `clade-model-inference`
- Understanding of JSON Schema for tool definitions

## Instructions

### Step 1: Use claude-embeddings-search instead
This skill has been replaced. The secondary Anthropic workflow is tool use / function calling, covered in full by `clade-embeddings-search`.

### Step 2: Key topics covered there
- Defining tools with JSON Schema input schemas
- Sending messages with tools attached
- Executing tool calls and returning results
- Building an agentic loop that runs until Claude stops calling tools
- Error handling for tool use edge cases

## Output
- Redirected to `clade-embeddings-search`
- Complete tool use patterns available there

## Error Handling
| Issue | Solution |
|-------|----------|
| Skill not found | Run `clade-embeddings-search` directly |
| Tool use errors | See tool validation patterns in that skill |

## Examples
```typescript
// Use claude-embeddings-search for the full tool use guide
const tools: Anthropic.Tool[] = [{
  name: 'get_weather',
  description: 'Get weather for a city',
  input_schema: {
    type: 'object',
    properties: { city: { type: 'string' } },
    required: ['city'],
  },
}];
const response = await client.messages.create({
  model: 'claude-sonnet-4-20250514',
  max_tokens: 1024,
  tools,
  messages: [{ role: 'user', content: "What's the weather in Paris?" }],
});
```
