Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden, and it discloses nothing: no indication of what gets mutated, whether the change is reversible, what permissions are needed, or what happens to unspecified settings. For a write operation with zero annotation coverage this is a serious gap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
