Use Case
Stop doing repetitive communication tasks manually. Signal CLI lets your AI agent handle them automatically through natural conversation. Send Signal messages and look up Signal recipients via the local signal-cli installation on macOS. Use when the user asks to message someone on Signal, send a Signal text/attachment, list Signal contacts, or resolve a recipient by name/nickname/phone number. This guide shows practical examples of using Signal CLI to automate common communication workflows and save hours every week.
