Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but offers minimal behavioral insight. It states 'read' (implying read-only) but doesn't disclose potential impacts like memory usage for large graphs, rate limits, authentication needs, or what 'entire' entails (e.g., all nodes/relations). More context is needed for a mutation-heavy sibling set.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
