## What is the Universal Registry?

The [Universal Agentic Registry](https://hol.org/docs/registry-broker/) is the connectivity layer for the autonomous web. One standards-compliant API to access agents from:

| Protocol | Description |
|----------|-------------|
| **Virtuals** | Tokenized AI agents |
| **A2A** | Google's Agent-to-Agent protocol |
| **MCP** | Anthropic's Model Context Protocol |
| **ERC-8004** | On-chain agent verification |
| **x402 Bazaar** | Agent payment rails |
| **OpenConvAI** | Conversational AI standard |
| **XMTP** | Decentralized messaging |
| **ANS** | Agent Name Service |

## What is this?

`CLAUDE.md` files provide Claude Code with project-specific context, coding standards, and guidelines. This repository contains templates with accurate HOL SDK examples.

## Quick Start

```bash
curl -O https://raw.githubusercontent.com/hashgraph-online/hol-claude-md/main/CLAUDE.md
```

## What's Included

### Accurate SDK Examples

The templates include real, working code for:

- `RegistryBrokerClient` initialization
- Agent search with filters
- UAID resolution
- Agent registration with auto top-up
- Chat conversations
- Vector (semantic) search
- Registry stats and queries

### Code Quality Standards

- TypeScript strict mode
- File naming conventions
- TDD workflow
- Validation checklist

## Example: Search for Agents

```typescript
import { RegistryBrokerClient } from '@hashgraphonline/standards-sdk';

const client = new RegistryBrokerClient();

const results = await client.search({
  q: 'weather',
  registry: 'hcs-10',
  limit: 10,
});
```

## Example: Chat with Agent

```typescript
const conversation = await client.chat.start({
  uaid: 'hcs10://0.0.123456/agent',
  auth: {
    accountId: process.env.HEDERA_OPERATOR_ID!,
    privateKey: process.env.HEDERA_OPERATOR_KEY!,
  },
});

const response = await conversation.sendMessage({
  content: 'Hello!',
});
```
