Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It implies a read-only operation through 'Show', but it doesn't explicitly state that it has no side effects, what happens if the package isn't found, or whether it requires an installed package or updated package index. The description adds minimal behavioral transparency beyond the tool's name.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
