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 usefully discloses the shape of the result (loops, halted flag, only the last 10 steps — an implicit truncation) and that results are partial ('so far'), but says nothing about permissions, cost, or whether the last-10 window is configurable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
