Jev-powered Hermes plugin for skill/model routing, typed assess, DOM/Cua computer use, adaptive reasoning effort with a per-turn receipt line, and FTS rerank.

## Good to know before installing

The default-on adaptive llm_request sends up to 1,200 characters of the current user message to TypeSafe/OpenRouter after Hermes redact_for_egress (no history or tool output); greetings and thanks are decided locally with no call; without the Hermes redactor it sends metadata only (disable via adaptive_reasoning_effort false). Separate default-on hosted skill routing sends up to 4,000 characters of the current user turn after Hermes redact_for_egress, plus skill names, to the same provider; without the redactor it stays local (opt down to local_only); light turns (greetings, closed acknowledgements, and read-only listings) skip that hosted call by default.

## 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 hermes-switchyard
```

2. Said no? Turn it on later:

```bash
hermes plugins enable hermes-switchyard
```

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
