@uuid: context references that decode a UUID or ULID for the model: @uuid:<id> takes a UUID in any common spelling (hyphens or not, braces, upper case, urn:uuid:) or a ULID, and attaches what its bits say, read the way RFC 9562 lays them out: version and variant in words, the creation time a v1, v6, v7 or ULID carries in UTC with how long ago, the clock sequence and node of a v1 or v6 and whether the node is random or looks like a network card (MAC) address, the local id and domain of a v2, a ULID's 128 bits written as a UUID, and the Nil, Max and RFC namespace UUIDs by name; up to 10 identifiers in one reference are compared by creation time; the TUI and Desktop composer preview an identifier as you type it.

## Good to know before installing

Reads only the text of the reference itself and the system clock, using Python's re, datetime and fractions; nothing is looked up; no network, no files read or written, no subprocess, no credentials read; the plugin keeps no copy of the identifiers, but the @uuid: reference and the decoded text become part of the message sent to your model provider and saved in the session history; register() only adds the @uuid: 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 uuid-ref
```

2. Said no? Turn it on later:

```bash
hermes plugins enable uuid-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
