Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full disclosure burden. "Show" weakly implies a read-only operation, but nothing confirms it, and there is no mention of cost, auth requirements, or whether the summary is cached/live — meaningful gaps for a memory-and-health dashboard tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
