The Agent Skills Directory

[COMMAND_EXECUTION]: The skill relies on the remindctl command-line utility to interact with the local macOS Reminders database. The instructions provide numerous examples of executing this binary to list, add, edit, and delete reminder data.
[EXTERNAL_DOWNLOADS]: The skill metadata and setup instructions direct the user to install the remindctl tool from a third-party Homebrew tap (steipete/tap/remindctl) or to build it from the provided GitHub source repository.
[PROMPT_INJECTION]: The skill processes reminder content (such as titles and list names), which introduces an indirect prompt injection attack surface. If an attacker places malicious instructions within a reminder's title, the agent could potentially interpret those instructions when fetching and processing the reminder list.
