@rfc:<number> context references: attach an IETF RFC's record from the RFC Editor to a message (title, status, date, authors, abstract, what it obsoletes and updates and what obsoletes or updates it, errata link).

## Good to know before installing

Sends one HTTPS GET per reference to www.rfc-editor.org/rfc/rfc<number>.json only (the referenced RFC number leaves the machine); no API key, no caching, no files written, no subprocess; register() only adds the @rfc: reference provider.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install rfc-ref
```

2. Said no? Turn it on later:

```bash
hermes plugins enable rfc-ref
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
