This is what I wanted to help with duplicate code detection, which is now a real problem with agentic programming since the agent tends to duplicate helper functions a lot in bigger codebases.

I ended up writing my own tool [1] that uses vector search, which works but can be unusably slow in large codebases.

I will give this a shot.

Thanks for posting this; I'm very interested in finding similar chunks of code in an AST-ish fashion, and using tree-sitter seems perfect.
