Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. It only says 'Read', which implies non-destructive behavior, but doesn't mention return format, potential size limits, metadata fields included, or any required context like targetOrg. The description adds little beyond the verb itself.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
