Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It mentions matching based on 'latest' data, but does not disclose whether this is a read-only operation, whether it triggers side effects, what it returns, or any prerequisites (e.g., agent existence). The lack of any behavioral details beyond a verb phrase leaves significant uncertainty.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
