TypeOpenClaw SKILL
Transparencyhigh
This skill appears safe. It is essentially a how-to guide for using two standard Linux calendar tools, vdirsyncer and khal, with common CalDAV providers like iCloud, Fastmail, and Nextcloud. There is no hidden code, no background scripts, and no evidence that the skill itself steals data or changes your system behind your back. The only network activity described is the normal calendar syncing you would expect from the tools it documents.
