Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the transparency burden. It does state the dual behavior (modify or add), but it fails to disclose important behavioral traits such as overwrite behavior, whether existing configurations are replaced, required authentication, or side effects. This is a significant gap for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
