What this skill does
Comprehensive Signal channel integration via signal-cli.
Signal is part of the Messaging & Channels category — messaging and channel skills that connect your agent to chat platforms. You can install it on its own or alongside other messaging & channels skills from the OpenClaw catalog.
How to install Signal
The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:
- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
signaland click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Signal with a single command:
openclaw skills add signal
This pulls signal from ClawHub and installs it into ~/.openclaw/skills/signal/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Signal
Once installed, Signal activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Manual install (advanced)
If you prefer manual installation:
- Click the Download .zip button above to grab
signal-1.0.2.zipdirectly from our S3 mirror. - Unzip into
~/.openclaw/skills/signal/(create the directory if it does not exist). - Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
