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 states the tool resolves the executable and reports version/configuration, which implies a read-only operation, but it does not mention side effects, failure modes, or whether it modifies any files. This is a minimal disclosure for a tool with no annotation support.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
