WHY IT NEEDS A POLICY

Why create_paragraph_draft needs a policy

This tool creates new draft content within a version-controlled drafts directory, which is a reversible write operation. It does not execute arbitrary code, delete data permanently, or move financial resources. The severity is medium because drafts are working materials, but miscreation could still require cleanup effort and impact the writing workflow.

From the tool's definition Tool description states it will 'Create a rough paragraph or scene draft' - the verb 'Create' indicates data creation. The draft exists in a drafts/ directory, separate from final chapters, making modifications reversible.
