Signal Notify

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.

How to install

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.
hermes plugins install signal-notify
Said no? Turn it on later:
hermes plugins enable signal-notify
Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
