Calendar

Security checks across malware telemetry and agentic risk

Overview

This calendar skill is a straightforward wrapper around gcalcli, but users should be careful because it can access and change real calendar events.

Install only if you trust gcalcli and are comfortable granting it access to the intended calendar account. Keep credentials out of prompts, logs, and shared shell history, and confirm the calendar, event title, date, and time before creating or deleting events.

Missing User Warnings

Medium
Confidence
93% confidence
Finding
The skill explicitly documents a destructive command, `gcalcli delete`, without warning that it can permanently remove calendar events matching a search term. In an agent or CLI-assist context, this increases the risk of accidental deletion, overbroad matches, and loss of user data because users may not realize the command is destructive or ambiguous.

Missing User Warnings

Low
Confidence
84% confidence
Finding
The skill references use of calendar API credentials and remote calendar access endpoints without any notice that calendar data and credentials are sensitive. This can lead users to expose private scheduling information or mishandle secrets in shared shells, logs, or agent contexts where command inputs and environment configuration may be visible.
