Calctl

This skill appears to be a macOS-only CLI wrapper for Apple Calendar (reads via icalBuddy, writes via AppleScript), but the registry metadata does not declare macOS as a required platform or the ical-buddy dependency. Before installing or enabling it: - Confirm you are on macOS and are comfortable granting Terminal/osascript automation access to control Calendar (Apple will prompt for these permissions). Calendar write access lets the skill create/modify events — consider privacy implications. - Manually install and vet ical-buddy (brew install ical-buddy) from a trusted source before using. The skill does not include an install script, so installation happens outside the skill. - Ask the skill author (or the registry) to update metadata to list required binaries and restrict the skill to macOS, and to provide exact commands the agent will run (so you can review them). - Prefer skills with a homepage or source repository so you can inspect the implementation. If you cannot verify the origin, avoid granting automation/Calendar permissions. I rated this 'suspicious' because the documentation and metadata are inconsistent and sensitive permissions (Calendar access) are implied but not documented; this could be benign oversight, but verify the points above before use.
