[hierarchy]

Gets base types, interfaces, and derived types for a 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.

Parameters

Name	Type	Required	Description
symbolKey	string	Yes	Opaque symbolKey from search_symbols, resolve_symbol, get_symbol_at_position, or any tool that returns symbolKey. Not a name.
includeBaseTypes	boolean	No	Include base types. Default is true.
includeInterfaces	boolean	No	Include interfaces. Default is true.
includeDerivedTypes	boolean	No	Include derived types. Default is true.
scope	json	No	Optional scope applied to derived type search.
derivedSkip	number	No	Derived type paging offset. Default is 0.
derivedTake	number	No	Derived type paging size. Default is 200.
pathStyle	string	No	Path style: 'absolute' (default) or 'relative' (to solution root).
