Show HN: Graphify C# – Compiler-accurate Find Usages for coding agents

Graphify C# is a free, headless Roslyn/MSBuild indexer that generates a deterministic JSON graph of compiler-resolved symbols, callers, references, implementations, inheritance and overrides across overloads, generics and projects. It can be installed as a .NET tool or agent skill, enabling coding agents to query exact overload usage, test-only references, zero-inbound symbols, and other semantic relationships without requiring an IDE or compiled DLL.
