Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It implies a read-only lookup but says nothing about what the guide actually contains (code samples, imports, SDK versions), whether results are static or versioned, or how large the output is. For a guidance-generation tool with zero annotation coverage this leaves significant behavior undisclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
