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

Love to see C# love. It's a great language. Super underrated in my opinion.

Unions coming in .NET 11 / C# 15 are going to be great.

I'm not sure when I would use something like this. My VS copilot already writes one-off scripts that use Roslyn to analyze code. I don't even have to prompt it to do this with gpt5.5+

C#/.NET feels unreasonably effective as a target for LLMs. The reflection and compiler services are not found anywhere else and have profound effects that HN still seems to be taking massive naps on.

Hey man, just wanted to say thanks! I pulled this down and adapted the skill for Unity development, keeping Graphify C# as an external analysis tool. My adapted skill isn’t publicly available yet, and I'm going to add it into my standard Unity Package development workflow to see if I can find some additional value in how the CLI and structured JSON make semantic information accessible to coding agents. I think this will help (maybe not on a full Unity game) but if you'r building multiple Unity Packages or have existing Unity Packages. Appreciate you sharing this!

The tool recommends you to use this skill <https://github.com/zachsaw/graphify-csharp/blob/main/.agents...>, but I wonder if this is the right approach if one just want to use this as a consumer in a .net project. It seems very wordy, but wording like these

  "Read the relevant design documents under docs/ before changing architecture."

makes me think that developing 'graphify the tool' and using 'graphify as a tool' are mixed up in the same document? How does an LLM keep track of both this gigantic skill and the user development problem at the same time?

Interesting! Have you tried it on any large code bases? I have to wonder if json is going do become unwieldy at the scale of millions of LOC - a SQLite db might be a better choice.

Interesting, thanks. Seeing agents querying compiled code using reflection to find references looks painful and inefficient. Made me want to help little buddy somehow, but had no idea how

Is this compatible with Graphify-Labs/graphify, w/r/t existing output formats?

compiler accurate find usages is exactly the context coding agents keep missing. how heavy is the roslyn integration at runtime, does it index on save or on demand

I don't understand why Microsoft and JetBrains aren't shipping versions of this. It seems like exactly what Roslyn was designed for
