WHY IT NEEDS A POLICY

Why complete_chore needs a policy

Without an explicit description, classification relies on the tool name and sibling context. 'Complete' typically marks a chore as done, which is a reversible state change (Write category). The low confidence (0.6) reflects the empty description and lack of direct evidence about what the tool actually does.

From the tool's definition Tool name 'complete_chore' and sibling tools include 'create_chore' and 'delete_chore', suggesting state-management of chore records. The tool appears to modify chore status (marking as complete) rather than deleting or executing external operations.
