Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It does disclose valuable behavior: default base is legi, and date returns the version in force at that date (default today), which is a meaningful temporal-snapshot trait. It says nothing about result volume, pagination, behavior of the limite parameter, or what happens on malformed query syntax.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
