WHY IT NEEDS A POLICY

Why generate_app_manifest needs a policy

The term 'generate' indicates data creation/production rather than retrieval (Read) or system state changes (Execute/Destructive). Severity is medium because app manifests control application behavior and dependencies—misuse could deploy incorrect configurations. Confidence is moderate due to the completely empty description; the tool's actual behavior and reversibility are unclear.

From the tool's definition Tool name 'generate_app_manifest' suggests creating or producing application configuration/metadata. The empty description prevents definitive categorization but 'generate' typically implies creation of new data artifacts.
