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 states the action ('Install') but doesn't describe what 'pub get' does beyond that (e.g., downloads packages, updates lockfile, may require internet). It lacks details on side effects, error handling, or typical runtime. This is inadequate for a tool with potential network/disk operations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
