Experimental model provider that runs Hermes turns on a Claude Pro/Max subscription through the official Claude Code CLI (the Agent SDK path), so no separate API key or per-token bill. Requires the claude CLI installed and logged in; the plugin checks for it at load, in hermes model, in the pickers and before every request, and refuses cleanly with the install hint when it is missing.

## Good to know before installing

Every turn is billed against your Claude subscription's Agent SDK allowance, and the provider inherits whatever account claude is logged into.

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 claude-subscription-directsdk
```

2. Said no? Turn it on later:

```bash
hermes plugins enable claude-subscription-directsdk
```

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
