Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is not a read-only tool, and the description accurately reflects read/write behavior without contradicting annotations. However, beyond the basic dual-action behavior, it does not disclose details such as what happens on a non-text clipboard, whether setting overwrites existing content, or possible failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
