WHY IT NEEDS A POLICY

Why like_article needs a policy

This tool writes a 'like' interaction to an article on Juejin. It requires authorization ('需要授权'), indicating it performs an authenticated state-changing operation. Since likes are generally reversible (can be unliked), this falls under Write rather than Destructive. Misuse could involve mass-liking content to manipulate engagement metrics, giving it a medium severity.

From the tool's definition 点赞文章 (like article) — creates a 'like' interaction on an article, which is a reversible write action (likes can typically be undone)
