Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: not whether the solid must pre-exist, whether the ids are stable across edits, what 'simplified' means, or the return shape. Read-only nature is only implied by the verb 'return'.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
