Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered externally. The description adds only the raw endpoint path, with no information on pagination, result volume, workspace scoping, or whether templates include system defaults. With this bar lowered by annotations, the marginal disclosure is thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
