Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full disclosure burden, and 'Create component' only signals a mutating operation — information already carried by the name itself. It says nothing about permissions, side effects, idempotency, or what happens on duplicate names. Slightly more informative than a bare noun but far short of what an unannotated mutation tool requires.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
