How do I grant the necessary permissions?

You must grant Calendar access to your terminal application (such as Terminal.app, iTerm2, or Ghostty) within macOS System Settings under Privacy & Security > Calendars.

Does this skill work on Windows or Linux?

No, this skill is specifically designed for macOS as it utilizes the native Apple EventKit framework and Swift CLI to interact with the local Calendar database.

Can I use this over an SSH connection?

No, macOS EventKit permissions typically do not apply over SSH sessions. This skill is intended for use in a local terminal session on your Mac.

Does it support time zones?

The CLI returns ISO 8601 timestamps. While EventKit handles the underlying data, the skill allows you to input dates in local time or standard ISO formats.

Can it distinguish between different calendars like Work and Personal?

Yes, the skill can list all available calendars and allows you to target specific ones using either their display name or unique EventKit identifier.
