Multi-model fusion router for Hermes: detects the model fleet your harnesses (Hermes, Codex, Claude, Grok) actually have installed and builds a Frontier -> Middle Manager -> Frontier routing structure with pinned models and provenance from execution records. `hermes fusion teams|validate|plan|run|index|report|status`.

## 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 fusion
```

2. Said no? Turn it on later:

```bash
hermes plugins enable fusion
```

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
