Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden for behavioral disclosure. It implies a read-only operation via 'Show,' but doesn't disclose potential scanning overhead, output format, or whether it checks local filesystem, registry, etc. This is a significant gap for a tool that could have side effects or require environment inspection.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
