Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description asserts 'Reads saved data only: it stores nothing, sends no email, and does not change the CV on file,' but the annotations declare readOnlyHint=false, i.e. the tool is not guaranteed read-only. The stated side-effect profile directly conflicts with the structured safety hint an agent would otherwise rely on.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
