Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, openWorldHint=true, so the safety profile is covered structurally. The description contributes nothing further: it does not say what 'content' actually is (YAML payload? rendered framework? file bytes?), whether authorization scoping applies, or what happens if the library is not loaded.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
