WHY IT NEEDS A POLICY

Why wp_scaffold_plugin needs a policy

While not immediately destructive, it modifies the WordPress environment by adding new code artifacts that could be used maliciously (e.g., scaffolding a plugin that an attacker then fills with backdoor code via separate means).

From the tool's definition Tool generates a plugin skeleton via WP-CLI scaffolding. The description states 'Generate a plugin skeleton,' which creates new files and directory structures in the WordPress installation that persist on disk.
