Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden but only states what the tool does, not how it behaves. It doesn't disclose if this is a read-only operation, requires specific permissions, returns real-time or cached data, has rate limits, or what format the output takes (e.g., text, JSON). This leaves significant behavioral gaps for a tool that likely interacts with a debug system.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
