Tool Icons
Tools automatically get icons based on their name:

|---|---|
search*, find* | Search |
read*, get* | File |
write*, create* | Pencil |
delete*, remove* | Trash |
send*, email* | |
| Default | Wrench |
With Agent Component
The Agent component handles tool lifecycle automatically:
import { Agent } from "@/registry/blocks/agent/agent"
<Agent
proxyUrl="/api/inference/proxy"
config={{
core_app: { ref: 'openrouter/claude-sonnet-45@0fkg6xwb' },
tools: [
{
name: 'search_web',
description: 'Search the web',
parameters: { query: { type: 'string' } },
requiresApproval: true, // Enable approval flow
},
],
}}
/>
