AI agents call get_deleted_tasks to retrieve information from Tick without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about previously deleted tasks from a trash/recycle bin. It performs a read-only query operation with no ability to modify, execute, or permanently delete data. The blast radius of misuse is minimal—an AI agent could only view deleted task information, not alter system state or cause harm.
From the tool's definition Tool name is 'get_deleted_tasks' and description states 'Get deleted tasks from the trash' — uses the verb 'Get', indicating retrieval of existing data with no modification or side effects.
