Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations to provide safety or side-effect hints, so the description carries the full burden. It only mentions loading and validating without disclosing whether it reads remote data, modifies anything, or what happens on validation failure. The word 'valida' is ambiguous about behavior (e.g., does it throw, return a result, or log outputs?).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
