Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the behavioral transparency burden. It only names the information returned (firmware/module versions) and gives no detail on behavior such as output format, handling of 'all' versus a specific printer, or whether any side effects could occur. 'Get' implies a read operation, but the description does not disclose anything beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
