Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses that the tool checks three specific components, which is useful, but it does not explicitly state whether it is read-only, what it returns, or any side effects (e.g., initiating WSL). The verb 'check' implies non-mutating behavior but lacks explicit detail.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
