Unofficial port of the standard T3 Code dark theme for Hermes Desktop. Palette, T3 composer, sidebar thread cards with project and branch, model labels and confirm dialogs. Scoped to its own theme; other themes are untouched.

## Good to know before installing

Unofficial T3 Code lookalike theme; its stylesheet restyles and hides some native Desktop controls, it reads local session metadata (branch, repo, provider) for sidebar cards, and it switches the active theme once on first enable.

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 t3-code-theme
```

2. Said no? Turn it on later:

```bash
hermes plugins enable t3-code-theme
```

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
