API capability pack for bounded Google Calendar API v3 calls against https://www.googleapis.com/calendar/v3 only. Reads the user's calendar list, calendar metadata, bounded event windows, individual events, and free/busy blocks. Bundles a scheduled daily agenda digest, an AI-assisted event prep brief, an approval-gated focus block creator, and an approval-gated event reschedule workflow. Enroll a Google OAuth bearer connection named google with the narrowest Calendar scopes needed for the installed operations. The pack intentionally excludes ACL/sharing mutation, secondary calendar creation/deletion/clear, watch channels, colors/settings/admin resources, event import, conference creation, attachments, arbitrary API passthrough, and unbounded event export.
