Could you build this?
Partial While scaffolding a CLI that parses ASTs via Tree-sitter is achievable, building reliable cross-file dependency and call graph impact analysis across various languages requires specialized compiler expertise.
What it would actually take: A production version requires integrating language-specific parsers or LSP implementations (often via Tree-sitter in Rust or Go) to build a multi-file symbol dependency graph. The core challenge is handling dynamic dispatch, reflection, and aliasing to accurately compute transitive impact without drowning the user in false positives.
