Apple Calendar CLI
PassAudited by ClawScan on May 10, 2026.
Overview
The skill is coherent for managing Apple Calendar, but users should notice it requires Calendar permission, can change or delete events, and depends on an external Homebrew-installed CLI.
Before installing, verify the Homebrew package source and only grant Calendar permission if you trust the CLI. When using the skill, require the agent to show and confirm exact event details before creating, updating, or deleting calendar entries.
Findings (3)
Artifact-based informational review of SKILL.md, metadata, install specs, static scan signals, and capability signals. ClawScan does not execute the skill or run runtime probes.
If granted, the tool can access calendar information such as event titles, times, locations, notes, and calendar identifiers.
The skill requires macOS Calendar permission, which can expose the user's event data to the CLI. This is expected for the stated purpose, but it is sensitive account-level access.
Calendar access permission must be granted (System Settings > Privacy & Security > Calendars)
Grant Calendar permission only if you trust the CLI and need this integration; review and revoke the permission in macOS Privacy settings when no longer needed.
An agent using this skill could create incorrect events, reschedule meetings, or delete calendar entries if the user request is misunderstood.
The skill's documented capabilities include mutating persistent calendar data. This is aligned with the stated purpose, but deletion and rescheduling can have real user impact if invoked incorrectly.
create, update, and delete events
Ask the agent to confirm event details before creating, updating, or deleting events, especially for work calendars, recurring events, or events with attendees.
The safety of the actual executable depends on the external Homebrew package, not just this instruction file.
The skill relies on an external Homebrew tap package that is not included in the reviewed artifacts. Installing a third-party CLI is purpose-aligned here, but its provenance and updates are outside this artifact review.
Install: `brew install sichengchen/tap/apple-calendar-cli`
Verify the Homebrew tap and package source before installing, and consider pinning or reviewing the CLI version used in sensitive environments.
