Schedule meetings by email and update the calendar

The poster built an agent that reads emails, checks calendar availability, replies with a meeting time and adds it to the calendar.

Done with a custom-built or unnamed agent

What they did

The poster built a background agent that scans their inbox for meeting requests, pulls the proposed date and time from the email, checks their calendar for conflicts, and either confirms the slot or suggests alternatives before blocking the time on the calendar. In comments, they said it uses limited permissions, no free-form actions, encrypted handling, and explicit authorization; for their use case it also accounts for in-person appointments, travel time, and distance between meetings.

How it went

They said they had used it for about a month and estimated it saved 3–4 hours a week of scheduling. The main shortcoming raised in the thread was trust: people were uneasy about giving inbox access, and the poster did not share a detailed technical implementation.

Worth knowing

The clearest practical catch is that this only made sense for them because existing scheduling tools did not handle travel time between in-person appointments.
