Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of disclosing behavior, but it only states the operation's purpose. It does not say whether the tool is read-only, what it returns on success or failure, whether it computes or just retrieves, or whether any side effects occur. 'Verify' implies inspection, but the actual behavioral contract is left unspecified.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
