Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that the tool performs a read operation and returns the full field schema, which provides behavioral context beyond the schema's parameter description. However, it does not mention error handling, authentication, or rate limits, which would be expected for a complete behavioral profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
