WHY IT NEEDS A POLICY

Why palace_autolink needs a policy

This tool modifies existing notes by inserting wiki-links into them. While the changes are reversible (links can be removed), the tool writes to potentially many notes automatically, which could have a broad blast radius if misused. It does not delete data or execute code, making Write the most appropriate category.
