AI agents call get_reminder_preferences to retrieve information from Todos without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves user preferences for reminders without side effects. It performs a read operation on stored configuration data. No data is created, modified, deleted, or executed. The low severity reflects that preference data is non-sensitive and read-only access poses minimal risk.
From the tool's definition Tool name and description indicate retrieval only: 'Get local reminder preferences' with parameters (due-soon window, SLA warning lead, desktop notify) are all configuration settings being queried, not modified or executed.
