WHY IT NEEDS A POLICY

Why duplicate_slide needs a policy

Duplicating a slide is a reversible write operation that creates new presentation content. It does not execute arbitrary code, delete data, move money, or trigger external side effects beyond presentation modification. The blast radius is minimal—at worst, a presentation contains extra slides that can be easily deleted. This is typical Write-category behavior for content creation tools.

From the tool's definition Tool name 'duplicate_slide' and description 'Duplicates a slide' indicate a reversible creation of content (a new slide copy). The operation adds data without permanently destroying or altering existing slides.
