WHY IT NEEDS A POLICY

Why update_scheme needs a policy

This tool creates or modifies data reversibly. It updates scheme records in a government database without deleting or destroying data. The modification is reversible (can be updated again), making it Write rather than Destructive. The impact is medium severity because administrative errors could affect government scheme information used by citizens, but the changes are not permanent or financial in nature.

From the tool's definition Tool name 'update_scheme' and description 'Update a government scheme record by ID. Pass only fields to change.' directly indicate modification of existing data.
