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
// 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?" }],
});Resources
