Sem: New primitive for code understanding – not LSPs, but entities on top of Git
Sem is a new developer tool that provides semantic understanding of Git repositories by tracking code entities like functions rather than raw lines. It offers features like entity-based diffs, blame, and impact analysis to improve developer productivity and AI agent accuracy.
Why it matters
It represents a shift in version control tooling, moving from text-based diffs to structural code analysis, which significantly enhances the reliability of AI-assisted coding workflows.
