Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of disclosing behavioral traits. 'Save coefficients' implies a write operation, but the description does not state whether it overwrites existing calibration data, if it is reversible, or what side effects it has. The agent gets no insight into the operational impact.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
