tug-refactor

Semantic code refactoring using tug. Use this skill when the user wants to: - Rename a function, class, method, or variable across multiple files - Change symbol names with automatic reference updates - Refactor identifiers while preserving semantic correctness Trigger patterns: "rename X to Y", "change the name of", "refactor the name", "update all references", "change the function/class/variable name" Note: tug currently supports Python only. Rust support is planned but not yet implemented.
