Zach Saw's graphify-csharp, created September 8 and at 53 stars, exposes compiler-accurate symbol navigation to agents by wrapping JetBrains Rider's analysis instead of grepping or hand-rolling an AST. C# 15 syntax, pushed again September 13, 42 points on HN. It targets the specific failure where an agent renames a symbol and misses call sites the compiler would have found, which is the single most common way an agent breaks a large typed codebase.
