Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must bear full burden for behavioral disclosure. It only states the action of opening a capture but does not explain side effects, prerequisites, or whether this is a read-only operation. The connotation of 'connect' versus 'open' is unclear.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
