Feishu Calendar

If you're building automations on top of Feishu (Lark), this gives you the full Calendar API wrapped up cleanly. You can create and update events, manage attendees, search across calendars, and even book meeting rooms by adding them as resource-type participants. The token handling is abstracted into a shared script that caches credentials and auto-refreshes when needed, so you're not wrestling with auth on every call. Covers the practical stuff like ACL management for shared calendars and pagination for bulk queries. Works well when you need to sync schedules, automate meeting creation, or build workflow triggers around calendar events without manually curling the Feishu API every time.
