Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full disclosure burden. It does add useful scope information ('across all boards'), and read-only behavior is self-evident from 'Search', but it says nothing about result limits, pagination, case sensitivity, or whether archived/closed cards are included.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
