WHY IT NEEDS A POLICY

Why set_view_representation needs a policy

The tool modifies a view's representation/configuration, which is a reversible change to workspace state. This is not a read operation (no data retrieval), not destructive (changes are reversible), and not execute-level arbitrary code execution. It falls squarely in the Write category—creating or modifying data reversibly.

From the tool's definition Tool name 'set_view_representation' performs an action that modifies state ('Switch a view'). This is a write operation that changes the representation or configuration of a view in Fusebase workspace.
