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 explicitly discloses data sources, licensing restrictions for CPT, cost per call, and output behavior (e.g., returns official short description for icd10 if it exists, validates structure for CPT). This provides complete transparency about the tool's behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
