Could you build this?

Partial While calculating CRAP (Change Risk Anti-Patterns) score is a straightforward formula (cyclomatic complexity combined with test coverage), parsing ASTs and test coverage formats across six distinct programming languages requires non-trivial language tooling integration.

What it would actually take: Written in Rust, Go, or Python, integrating language-specific parsers (via Tree-sitter or native compiler AST interfaces) and parsing disparate coverage report formats (LCOV, JaCoCo, Go cover, etc.). The challenge is robustly mapping heterogeneous language AST constructs to normalized cyclomatic complexity and cross-referencing with coverage line maps.
