WHY IT NEEDS A POLICY

Why toggle_todo needs a policy

Toggling a todo item modifies its completion state, which is a reversible write operation. It does not delete data or execute code. Severity is medium because an AI agent misusing this could flip the state of many todos, disrupting task tracking, but the action is reversible.

From the tool's definition Toggle a todo — toggling a todo item changes its state (e.g., complete/incomplete), which is a reversible modification of existing data.
