Local System One / Laya Typed Decisions control plane for Hermes Agent. Sends bounded turn data to a configurable sidecar for reversible OFF/Shadow/Canary routing decisions, with explicit Canary acknowledgement and fail-open behavior.

## Good to know before installing

Executes nothing and does not start the sidecar. In Shadow/Canary mode, Search and Model Tier may POST the current task plus bounded recent conversation context; Notification Shadow may POST the completed turn's final assistant response (up to 6000 chars) plus lifecycle metadata. The default sidecar URL is loopback 127.0.0.1:8787 but is user-configurable to any host and no auth header is added. Notification is observation-only: the plugin never sends a push/message/webhook and persists decision metadata, not raw response text. Its only request mutations, in acknowledged Canary mode on the first provider call of a turn, are removing web_search/web_extract tools for audited deterministic no-Web rules and (off by default) lowering reasoning_effort for gemini-3.8-flash-tiered on audited hard-fast rules. The sidecar (same repo, separate pip install, Apple-Silicon MLX/CoreML) is a text classifier that downloads a pinned Hugging Face model.

## 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 local-system-one-hermes
```

2. Said no? Turn it on later:

```bash
hermes plugins enable local-system-one-hermes
```

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
