Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Summary counts' strongly implies a read-only aggregate operation and the zero-parameter schema makes it low-risk, but the description never explicitly asserts read-only behavior or says whether counts span all workspaces or just the current context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
