Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are present, so the description carries the full burden. It discloses the side effect 'markeert het project als gesloten', but this largely restates the meaning of 'close'. It does not mention reversibility, permissions, or consequences of closing a project.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
