Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the full burden is on the description. The description only states that it solves an equation, but does not disclose side effects, return format (though output schema exists, its content is not described), required prerequisites, or limitations. The agent is left uninformed about behavior beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
