Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of behavioral disclosure. It does disclose the traversal semantics ('through calls / references / accesses') and implies a read-only operation via the verb 'Find'. However, it does not disclose details such as the exact return format, behavior when no path exists, or any limitations like depth or cycle handling. This is partial transparency, warranting a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
