A side agent rereads the conversation while Hermes works on longer turns and surfaces the one thing you might have missed — a silent tradeoff, an unverified result, an irreversible action — as a dismissible note above the prompt.

## Good to know before installing

On tool-using turns in Desktop, CLI and TUI (configurable via `platforms`), sends up to 12,000 characters of the recent conversation, including clipped tool calls and results, to Hermes's configured auxiliary model up to five extra times per turn (45 s cooldown), which adds model cost; notes are stored in the plugin's own data folder.

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 you-should-know
```

2. Said no? Turn it on later:

```bash
hermes plugins enable you-should-know
```

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
