Signal texts when a Hermes turn pauses, fails or is interrupted, and when Hermes waits on a clarify question, approval or sudo prompt. Sends through the user's own signal-cli HTTP daemon (the same SIGNAL_* settings as the core Signal gateway); skips Signal-origin, cron and subagent turns, and dedupes identical texts within 60s. Outbound-only, no input channel.

## Good to know before installing

Enabled turns POST to SIGNAL_HTTP_URL (plain HTTP unless that URL is https), which signal-cli delivers as a Signal message; by default each text includes up to 300 characters of the final reply (not secret-redacted) or of the redacted question/command (reply_chars: 0 sends none); sudo passwords and clarify answers are never seen; nothing is stored on disk, at most 64 clipped reply previews are kept in memory, and each send runs on a short-lived daemon thread with a 20s timeout.

From the plugin's catalog listing.

## How to install

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

```bash
hermes plugins install signal-notify
```

2. Said no? Turn it on later:

```bash
hermes plugins enable signal-notify
```

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
