Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. 'Deletes a transport' indicates a destructive operation but provides no details about permissions required, whether deletion is reversible, what happens to associated data, system impacts, or error conditions. For a destructive operation with zero annotation coverage, this is inadequate.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
