Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description partially compensates by noting the data type (UINT32) and default (OFF). However, it does not explain what the returned value means (e.g., 0 includes debug, 1 excludes) or any side effects. It adds some insight beyond the empty schema but lacks full disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
