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 it detects the plugin without explaining whether it is read-only, what it returns, whether it caches results, or what side effects (if any) occur. For a detection tool this is likely safe, but the description does not explicitly say so.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
