WHY IT NEEDS A POLICY

Why apply_agent_pack needs a policy

This tool creates or modifies project files and structure by applying an agent pack template to the current project. While it includes verification ('fingerprint verification'), the core action is materialization of code/configuration into the project, which is reversible (making it Write rather than Destructive).

From the tool's definition Tool name 'apply_agent_pack' combined with description 'Apply a saved agent pack to the current project' indicates it modifies the project state. The mention of 'scaffolded materialization' suggests generation or creation of project artifacts.
