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 structurally. The description adds essentially nothing behavioral beyond restating the identifier type: no note on failure when the id is unknown, no auth/credential requirement, no indication of what a project payload contains.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
