Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the burden of behavioral disclosure. It does state the core behaviors: automatic upload and registration. However, it does not disclose side effects such as overwriting an existing prop sheet, whether the prop must already exist, or what response is returned after upload.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
