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 mentions resolving and downloading dependencies, but does not disclose that the operation modifies pubspec.lock and .dart_tool/package_config.json, requires network access, or may be slow. For a mutating operation this is a significant omission.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
