This is a native macOS Calendar integration that lets Claude schedule events, set reminders, and create recurring meetings through AppleScript. It handles the tricky bits like natural language date parsing ("next Monday at 2pm"), calendar selection, and recurrence rules without hitting locale formatting issues. The JSON-based interface is clean and the skill correctly guards against read-only calendars. Worth noting that it requires you to list calendars first before creating events, which is the right approach but adds a step. If you're on macOS and want Claude to actually modify your calendar instead of just suggesting events, this does the job. Works best when you're specific about times and calendar names.
