This pulls merge-pdf from ClawHub and installs it into ~/.openclaw/skills/merge-pdf/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Merge PDF

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
merge-pdf-1.0.0.zipdirectly from our S3 mirror. - Unzip into
