SEM: GIT-BASED CODE UNDERSTANDING WITHOUT LSP

Sem reimagines how code analysis tools work by treating Git repositories as the foundation for understanding code structure. Instead of building yet another LSP implementation, the system uses Git's existing infrastructure to model code entities and their relationships. The approach offers potential advantages for code analysis, refactoring, and navigation tasks. By operating at the Git level, Sem can leverage version control history and distributed workflows natively, without requiring language-specific parsers or complex server architectures. The project has generated moderate interest in developer communities, with 104 points and 38 comments on Hacker News, suggesting growing awareness around alternative approaches to code tooling. The work challenges conventional wisdom about how modern IDEs and development tools should handle code comprehension. Ataraxy Labs presents Sem as a new primitive—a foundational building block—that could enable simpler, more efficient tools for developers working across multiple languages and project structures.
