WHAT IT DOES

WHY IT NEEDS A POLICY

Why uncomplete_task needs a policy

This tool modifies task data reversibly by changing a task's completion status from done to not done. It is a Write operation because it updates data without destructive consequences—the original task data remains intact and the change is reversible (the task can be completed again). The blast radius is minimal as it only affects individual task state with no cascade effects or data loss.

From the tool's definition Tool name 'uncomplete_task' with description 'Reopen a completed task' indicates modification of existing task state from completed to incomplete.
