What problem does it solve?
Letting an agent touch your real calendar usually requires custom Microsoft OAuth and event CRUD code you did not plan to write this week.

Microsoft 365 users who want IDE-resident agents to schedule, update, or query Outlook Calendar while building or running a solo business.
Skip if: Google Calendar-only stacks, shared-room resource booking at enterprise scale, or teams forbidding agent write access to production calendars.
