Compiler-Accurate Semantic Analysis

Graphify C# is a new tool designed to provide coding agents with compiler-accurate 'Find Usages' capabilities for C# projects. It operates as a headless Roslyn/MSBuild indexer, processing C# source code to generate deterministic, queryable semantic information. This includes details on compiler-resolved callers, references, implementations, inheritance, and overrides, functioning correctly across overloads, generics, and multiple projects.

Addressing Limitations of Text Search

Traditional text-based searches for code analysis often fail to distinguish between overloads, identify the correct project for a caller, or confirm the intended interface implementation. Graphify C# addresses these issues by loading projects via MSBuild and querying Roslyn to understand the precise meaning of each symbol. It then emits stable identities and directed relationships, offering semantic evidence rather than mere text-match counts.

Integration and Output

The tool generates a single JSON document containing nodes, edges, and hyperedges, which can be directly consumed by coding agents, queried with tools like `jq`, or integrated into custom code. Supported inputs include `.sln`, `.slnx`, `.csproj`, and SDK file-based `.cs` applications. The repository's SDKs, packages, and MSBuild inputs must be available locally for Graphify C# to function.

Agent Skill Integration

Graphify C# includes a skill that teaches agents when to refresh the index, how to navigate semantic edges, and the boundaries of static analysis. This skill can be installed in Codex-compatible projects or adapted for platforms like Claude Code, allowing agents to leverage the generated semantic graph effectively for code understanding and analysis tasks.

How outlets covered it

Graphify, an open-source tool launched in April 2026, transforms codebases and documentation into multimodal knowledge graphs to improve AI coding workflows. This approach addresses the limitations of AI coding agents in handling multi-file reasoning and deep dependencies by providing structured context, which matters for developers using AI assistants on complex software systems.

Graphify C# is a new, free, headless Roslyn/MSBuild indexer that converts C# source code into queryable semantic data, including compiler-resolved callers, references, and inheritance. This tool allows coding agents like Codex and Claude Code to perform accurate 'Find Usages' functionality, overcoming limitations of text-based searches by understanding symbol meanings across projects and overloads.
