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 tool retrieves source code but doesn't describe what 'retrieve' entails (e.g., read-only operation, format of returned data, error handling, or authentication requirements). This leaves significant gaps for a tool that presumably accesses system resources.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
