Google Calendar CLI

Security checks across malware telemetry and agentic risk

Overview

This is a straightforward Google Calendar CLI helper, but it can read and change real calendar data once the user authorizes it.

Install only if you trust the gog CLI and Homebrew tap. Use a test or non-critical calendar while experimenting, review any create/update/delete or looped commands before running them, protect OAuth client secrets and tokens, and revoke Google Calendar access when you no longer need it.

Vague Triggers

Medium

Confidence: 92% confidence
Finding: The description is broad enough to trigger on many ordinary calendar-related requests without clear boundaries or confirmation requirements. In an agent setting, that increases the chance the skill is invoked in contexts where the user did not explicitly authorize calendar access or modification, which can lead to unintended disclosure or changes to calendar data.

Missing User Warnings

Medium

Confidence: 95% confidence
Finding: The examples show commands that create and update events, and later include scripted bulk creation, without warning that they change live Google Calendar data. Users or agents may copy and run these commands assuming they are harmless examples, causing unintended calendar modifications at scale.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The OAuth setup instructions grant the tool access to the user's Google Calendar account but do not warn about the privacy implications or the sensitivity of the credentials and account data involved. This can lead users to authorize broad access without understanding that the tool may read or modify personal or organizational calendar information.
