Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of disclosing behavior. It only states it retrieves a summary, but does not mention whether it aggregates data, what parameters are required, potential side effects, or return format. This is a significant gap for a tool that may have side effects or specific data handling.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
