Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, openWorldHint=true, and destructiveHint=false, so the safety profile is partially covered. However, this is a PUT-style mutation where the critical behavior is unaddressed: whether omitted fields are cleared or preserved, what permissions are required, and what gets changed on the server. With 4 opaque parameters and no output schema, the description carries a large remaining burden and does not meet it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
