Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Redeem' implies a financial transaction that likely modifies state (e.g., reducing shares), but the description doesn't specify if this is destructive, requires authentication, has rate limits, or what the expected outcome is (e.g., asset transfer, confirmation). It lacks any behavioral details beyond the basic action.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
