Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description transparently mentions that query and fragment components are dropped, which is an important behavioral detail. However, it does not describe error handling for invalid URLs, whether the input must be an absolute URL, or any other edge-case behavior. With no annotations provided, the description carries the full burden but only partially fulfills it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
