Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry the full burden. 'Restart' implies stopping and starting, but the description does not disclose side effects, potential downtime, or whether it interrupts existing sessions. It only states the output (URL and port), which is partially informative but leaves out important behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
