## How to use

2. Read that sub-skill’s `SKILL.md` and its `rules/` for step-by-step guidance.
3. For SDK or API details, use the xmtp-docs skill (index + specific page fetch).

## Quick start

Install the Agent SDK, create an agent from env, handle text, then start:

```bash
npm install @xmtp/agent-sdk
```

Create the agent and handle messages using patterns from **building-agents** (setup, events, middleware). For commands, attachments, reactions, groups, transactions, inline actions, or resolution, use the corresponding sub-skill above.
