Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It's a read-only listing operation, but the description doesn't state the return format, whether pagination is involved, whether it requires a prior 'doppler setup' for the optional project parameter, or what happens when no project is provided. The description is too thin to disclose behavioral traits beyond the obvious 'list all' semantics.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
