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 only states 'Get details' and does not mention response format, error handling (e.g., not found), or any prerequisites, leaving the agent without critical behavioral context beyond the obvious read-only nature of 'get'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
