WHY IT NEEDS A POLICY

Why save_build needs a policy

The tool creates or stores a new car build configuration, which is a standard data creation operation. It is reversible (a saved build can be deleted), so it does not qualify as Destructive. There are no code execution, financial, or data deletion aspects.

From the tool's definition Tool name 'save_build' and description 'Save the current car build configuration under a specific name' indicate creation or storage of a new build record. This is a reversible write operation (builds can be deleted via sibling tool 'delete_build').
