Is this for checking what Claude Code just did to your repo?

It can do that, but that's a small slice of what it does. sem parses your codebase into entities (functions, classes, methods) and builds a dependency graph across files.

So instead of line level analysis the whole granularity of seeing changes and tracking thing shifts to entities. It helps in attention mapping of your agent and lets you track the changes faster.

LSPs have been doing it for quite long but using treesitters is faster even tho type awareness is not great with this approach but overall working across multiple languages with a single tool can be quite helpful.

The tool looks great! Thanks for sharing.

Appreciate it!

1. Do you expose this dependency graph so folks can play with it / build interesting things on top? An interesting example would be to understand whether/how a version bump on one of your dependencies might affect your code.

2. What would it take to add a new language? I'm interested in using this with Julia.
