This looks great! Duplication and dead code are especially tricky to catch because they are not visible in diffs.
Since you mentioned the implementation details, a couple questions come to mind:
1. Are there any research papers you found helpful or influential when building this? For example, I need to read up on using tree edit distance for code duplication.
2. How hard do you think this would be to generalize to support other programming languages?
I see you are using tree-sitter which supports many languages, but I imagine a challenge might be CFGs and dependencies.
I’ll add a Qlty plugin for this (https://github.com/qltysh/qlty) so it can be run with other code quality tools and reported back to GitHub as pass/fail commit statuses and comments. That way, the AI coding agents can take action based on the issues that pyscn finds directly in a cloud dev env.
