WHY IT NEEDS A POLICY

Why save_presentation needs a policy

This tool creates or modifies a markdown file, which is a reversible operation (the file can be edited, replaced, or deleted later). It does not delete data, execute arbitrary code, or cause financial impact. The blast radius of misuse is limited to creating unwanted presentation files in the presentations directory, which can be easily remediated.

From the tool's definition Tool name 'save_presentation' and description 'Saves the current presentation to a markdown file in the presentations directory' indicate file creation/modification without deletion or irreversible destruction.
