[hierarchy]

Finds derived types of a base type. Requires a symbolKey.

Why this tool exists

Behavior in C# often lives behind inheritance, interfaces, overrides, and member chains.

How it helps the agent

The model can map base and derived relationships before editing contracts or investigating polymorphic behavior.
