Could you build this?
No Building a comprehensive static analyzer and type checker for complex nested GitHub Actions YAML and expression syntax requires compiler design and AST evaluation expertise.
What it would actually take: A real linter requires writing an AST parser and semantic analyzer in Go or Rust that strictly validates GitHub Actions schema, models the expression evaluation engine (${{ ... }}), simulates contextual matrix expansions, and embeds external tools like ShellCheck and PyFlakes for embedded script validation.
