Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly/idempotent/non-destructive and closed-world, so the bar is lower, yet the description adds real context: one record per state or DC, sourced from state rules of professional conduct and bar pages, with per-source provenance and the date read. The 'not legal advice' caveat is a meaningful disclosure the annotations do not carry. Return format and pagination are not covered, which keeps it from a 5.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
