WHAT IT DOES

WHY IT NEEDS A POLICY

Why todoist_create_task needs a policy

Creating a task is a Write operation: it adds new data to the system but does not irreversibly destroy data or execute arbitrary code. The blast radius is medium because an AI agent could spam task creation, cluttering a user's task list, but the impact is recoverable through deletion. No financial transactions or destructive operations are involved.

From the tool's definition Tool name 'todoist_create_task' and description 'Create a new task in Todoist' indicate data creation. This is a reversible operation—tasks can be deleted or modified later.
