Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It communicates that this is a spec (implying read-only/documentation) and describes the content, but it does not explicitly state there are no side effects, what the output format is, or any constraints. The description adds some context beyond the name but lacks explicit behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
