Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must disclose behavioral traits, but it only states 'Get 4D database schema information' without detailing what the operation returns, whether it requires prior login, or how the 'all' parameter affects the output. The verb 'Get' implies a read-only operation, but no further behavioral context is given.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
