NW-REFACTOR: Systematic Code Refactoring

Wave: CROSS_WAVE Agent: Crafty (nw-software-crafter) Command: *refactor

Overview

Applies the Refactoring Priority Premise (RPP) — cascading 6-level hierarchy where lower levels complete before higher. Levels: L1 Readability|L2 Complexity|L3 Responsibilities|L4 Abstractions|L5 Design Patterns|L6 SOLID++. Each builds on previous. For complex multi-class refactorings, agent applies Mikado Method internally.

Context Files Required

• src/* - Production codebase
• tests/* - Test codebase

Agent Invocation

@nw-software-crafter

Execute *refactor for {target-class-or-module}.

Context Files:

• src/*
• tests/*

Configuration:

• level: 3 # Shorthand: --from=1 --to=3 (RPP range)
• from: 1 # Start RPP level (default: 1)
• to: 3 # End RPP level (default: same as level)
• scope: module # file/module/project
• method: extract # extract/inline/rename/move
• mikado_planning: false # Use Mikado Method for complex refactorings

Success Criteria

• Code quality metrics improved (measured before/after)
• All tests passing after refactoring
• Refactoring levels applied in sequence (L1 before L2, etc.)
• Technical debt reduced measurably

Examples

Example 1: Module-level readability refactor

/nw-refactor src/auth/token_manager.py --level=2 --scope=module

Crafty applies RPP L1-L2: rename ambiguous variables|extract magic numbers into constants|remove dead code (L1), then simplify conditionals|extract long methods (L2).

Example 2: SOLID-level design refactor

/nw-refactor src/billing/ --level=6 --scope=module --mikado_planning=true

Crafty uses Mikado Method for multi-class refactoring, applies dependency inversion|interface segregation across billing module.

Example 3: RPP range sweep (L1-L3)

/nw-refactor src/des/domain/ --from=1 --to=3 --scope=module

Sweeps L1 readability|L2 complexity|L3 responsibility smells. Cascade rule: L2 only after L1 clean, L3 only after L2 clean.

Example 4: Targeted single-level refactor

/nw-refactor src/des/cli/verify.py --level=3 --scope=file

Targets L3 responsibility smells only (Large Class, Feature Envy, Shotgun Surgery). Assumes L1-L2 already clean.

Expected Outputs

src/*                              (refactored production code)
tests/*                            (refactored test code)
