# Rust Refactoring Frameworks

This skill teaches you to look at working Rust code and see unnecessary complexity. Every refactoring starts with a diagnostic question, follows a transformation pattern, and ends with a self-review checklist.

---

## The Two Refactoring Philosophies

Before touching code, decide which mode you are in.

**Defensive mode:** Add abstraction for safety. Split types. Create From bridges. Audit every consumer. Use when: security-critical code, type evolution, multi-crate dependencies.

**Offensive mode:** Delete indirection. Remove forwarded parameters. Collapse layers. Use when: the abstraction adds complexity without adding safety, the mediator just forwards, the parameter is always None.
