Can it automatically generate meet links when booking?

Yes. When building the `create_event` request, the agent can structure event metadata that explicitly flags conferencing generation. You get a Google Meet URL seamlessly inside the payload.

How does the tool handle multiple calendars (e.g. personal and work)?

It requires querying the primary or specified secondary calendar IDs. By default, it operates on 'primary'. You can command the agent to use `list_calendars` to pick and choose exactly which specific agenda it targets.

Will the AI delete historical meetings completely if I ask it?

While specific `delete_event` tools track individual IDs, bulk deletions and catastrophic operations are architecturally suppressed for safety. Removing isolated tasks works strictly one-by-one by direct matching.
