Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full responsibility for disclosing behavior. It only mentions 'live' and 'beta,' but fails to state whether the operation is read-only, what data sources are used, or how the risk profile is computed. This leaves significant unknowns for an agent.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
