If you're on macOS and want Claude to manage your calendar and reminders without leaving the terminal, this is the setup. It uses osascript for Calendar events and reminders-cli for tasks, following GTD principles to help you decide what goes where. The bilingual interface is a nice touch if you work in English and Chinese. The cross-project weekly planning feature is genuinely useful if you maintain schedule YAML files across repos. It will parse your project timelines, flag capacity conflicts, and suggest time blocks. Just know you'll need to grant terminal permissions in System Settings first, and osascript can be slow for reminders, which is why the skill defaults to the CLI tool.
