Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. While 'withdraw' implies a write/mutation operation, the description doesn't specify permission requirements, whether this action is reversible, potential side effects, or what happens to the withdrawn collateral. For a financial transaction tool, this is a significant gap in behavioral context.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
