Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the behavioral burden. The verb 'Scan' implies a read-only analysis and 'potential' accurately suggests heuristic reporting, but the description does not explicitly state that no files are modified, whether includes are followed, or whether findings are returned as a list, message, or diff.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
