Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full disclosure burden but says nothing about pagination limits (the schema's `limit` defaults to 50, implying truncation risk), result ordering, or the shape of returned algorithm entries. Nothing indicates whether the tool is a pure read (safe to call freely) or has side effects, which matters for an agent deciding whether to probe it.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
