Ataraxy-Labs/sem

Semantic version control => entity-level diffs, blame, and impact analysis on top of git. 28 languages via tree-sitter. Built for coding agents.

About the project

sem is a Git-based semantic version control tool that compares changes to code entities such as functions, methods, and classes instead of individual lines. It helps developers and coding agents review changes, trace responsibility, and assess their impact across repositories. Catalogue add-ons provide agent integrations and workflows for operating sem.

This repository also configures its own agents. See what sem tells them →
