How to install Input Guard

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

  1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
  2. Open the in-app Skills panel.
  3. Search for input-guard and click Install.
  4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Input Guard with a single command:

openclaw skills add input-guard

This pulls input-guard from ClawHub and installs it into ~/.openclaw/skills/input-guard/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Input Guard

Once installed, Input Guard 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:

  1. Click the Download .zip button above to grab input-guard-1.0.1.zip directly from our S3 mirror.
  2. Unzip into ~/.openclaw/skills/input-guard/ (create the directory if it does not exist).
  3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
