WHY IT NEEDS A POLICY

Why scratchpad_complete needs a policy

The tool creates or modifies data reversibly by updating task completion status within the scratchpad workspace. It does not delete data (ruling out Destructive), execute arbitrary code (ruling out Execute), involve financial transactions (ruling out Financial), or merely retrieve information (ruling out Read). The operation is a metadata update in a persistent workspace system, which fits the Write category.

From the tool's definition Tool name 'scratchpad_complete' and description 'Mark a scratchpad task as complete' indicate a state-change operation that modifies task metadata (completion status) in the MongoDB-backed workspace.
