Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden and mostly fails: it never says whether a real booking occurs, what 'confirm' does, whether a token is required, or what side effects follow. The '(dry-run)' hint is the only behavioral disclosure, and it is contradicted by 'REAL RIDE' in the same line.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
