Refactor: $ARGUMENTS

Rules

NEVER change behavior — only improve structure
ALWAYS run tests before AND after
Make small, incremental changes
Each change should be independently verifiable

Steps

Run tests first — establish baseline
```
[test command]
```
If tests fail BEFORE refactoring, STOP and tell the user.
Read the code to refactor and understand it fully
Read the tests for this code — understand what behavior is expected
Identify refactoring opportunities:
- Extract method (function too long)
- Extract variable (complex expression)
- Rename for clarity
- Remove duplication (DRY)
- Simplify conditionals
- Replace magic numbers with constants
- Reduce nesting depth
- Split large files
- Improve type safety
Apply changes incrementally
- One refactoring at a time
- Run tests after each change
- If tests fail, revert immediately
Run full test suite
```
[test command]
```
