Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry the behavioral burden. It says 'Close (archive)' which implies the project is archived rather than deleted, but it does not state whether the action is reversible, what happens to associated cards/issues, whether it requires special permissions, or what the response will be.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
