The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill directs the installation of the remindctl utility from a third-party Homebrew tap (steipete/tap/remindctl) and references building the tool from source using pnpm.
[COMMAND_EXECUTION]: The skill's primary functionality relies on executing the remindctl binary via the shell to interact with the macOS Reminders database.
[PROMPT_INJECTION]: The skill possesses an indirect prompt injection surface as it processes untrusted data.
Ingestion points: The agent ingests data from the local Apple Reminders database through commands like remindctl today or remindctl all.
Boundary markers: There are no explicit delimiters or instructions provided to the agent to distinguish between its own instructions and the content retrieved from reminders.
Capability inventory: The skill has the ability to read, create, modify, and delete reminders, and executes shell commands via the remindctl binary.
Sanitization: The skill does not implement sanitization or validation of the text content within reminders before it is returned to the agent context.
