Per-turn model AND reasoning-effort routing, decided by TypeSafe Jev, which rewrites the outgoing Ollama:Cloud provider request itself via the llm_request middleware. Every other catalog router picks a model and stops, and the two entries that touch reasoning effort move it by hand; this one decides both per turn. Ollama:Cloud only — no other provider is routed, and every failure path leaves the request byte-identical to a plugin-disabled run.

## Good to know before installing

Sends the current user message and up to 4 previous turns to OpenRouter's Decisions API (typesafe/jev, billed to your OpenRouter key) on every routed turn.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs (this one needs `OPENROUTER_API_KEY`), then asks whether to turn it on.

```bash
hermes plugins install jev-effort-router
```

2. Said no? Turn it on later:

```bash
hermes plugins enable jev-effort-router
```

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
