Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden and mostly fails it: it never states whether the tool is read-only, whether it inspects a live site, what inputs it consumes, or what exactly is returned. The one useful disclosure is 'delivered as a copy-paste prompt pack with examples', which hints at a static text deliverable rather than an analysis — but it is buried in marketing phrasing and never confirmed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
