get_method_signature

[analysis]

Gets detailed information about a method signature (parameters, return type, docs, and location) by method name or symbolKey. Supports fully qualified method names when containingTypeName is omitted; a symbolKey disambiguates overloads.

Why this tool exists

Agents need enough source and member detail to act, but whole files are often too much context.

How it helps the agent

These tools provide bounded, structured slices of types and methods so the model can inspect intent without flooding the prompt.

Parameters

Name	Type	Required	Description
methodName	string	No	Method name to analyze. If containingTypeName is omitted, you can pass a fully qualified name like 'Namespace.Type.Method'. Provide this or symbolKey.
symbolKey	string	No	A symbolKey from search_symbols/resolve_symbol (preferred; precise for overloads). Provide this or methodName.
containingTypeName	string	No	Optional containing type name filter.
projectName	string	No	Optional project name filter.
pathStyle	string	No	Path style: 'absolute' (default) or 'relative' (to solution root).
