nw-progressive-refactoring

nw-progressive-refactoring is a skill for Claude Code from nWave-ai/nWave. It costs 34 tokens per session (1,915 once invoked), scanned A, original, MIT.

A structured approach to improving existing code through six levels, from clearer names and less clutter to simpler design and broader architectural changes. It includes common code smells and matching refactoring techniques.

In plain words
What is it for?
Use it to identify code and test smells, plan small code transformations, reduce duplication and complexity, and organize responsibilities.
Why use it?
It gives refactoring work a clear order and helps address simple readability problems before more complex design changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nw-progressive-refactoring scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Progressive Refactoring (Refactoring Priority Premise)

Based on the Refactoring Priority Premise (RPP) from the Alcor Academy curriculum.

RPP Levels (L1-L6)

Execute levels in mandatory sequence. Lower levels before higher.

Level 1: Foundation (Readability)

Focus: eliminate clutter, improve naming, remove dead code. Smells: Dead Code | Comments (how-comments) | Speculative Generality | Lazy Class. Transformations: Rename | Extract (variables/constants) | Safe Delete. Impact: 80% of readability improvement value. Test smells: Obscure Test | Hard-Coded Test Data | Assertion Roulette.

Level 2: Complexity Reduction (Simplification)

Focus: method extraction, duplication elimination. Smells: Long Method | Duplicate Code | Complex Conditionals. Transformations: Extract (methods) | Move (common code). Impact: 20% additional readability improvement. Test smells: Eager Test | Test Code Duplication | Conditional Test Logic.

Level 3: Responsibility Organization

Focus: class responsibilities, coupling reduction. Smells: Large Class | Feature Envy | Inappropriate Intimacy | Data Class | Divergent Change | Shotgun Surgery. Transformations: Move | Extract (classes). Test smells: Test Class Bloat | Mystery Guest | General Fixture.

Level 4: Abstraction Refinement

Focus: parameter objects, value objects, abstractions. Smells: Long Parameter List | Data Clumps | Primitive Obsession | Middle Man. Transformations: Extract (objects) | Inline | Move.

Level 5: Design Pattern Application

Focus: Strategy | State | Command patterns. Smells: Switch Statements | complex state-dependent behavior. Transformations: Extract (interfaces) | Move (to polymorphic structure).

Level 6: SOLID++ Principles

Focus: SOLID principles, architectural patterns. Smells: Refused Bequest | Parallel Inheritance Hierarchies. Transformations: Extract (interfaces) | Move (responsibilities) | Safe Delete (violations).

RPP Cascade Rule

MANDATORY: complete each level fully before moving to the next. Do not skip levels. 80% of refactoring value comes from readability improvements (L1-L2). Focus effort on L1-L2 for maximum impact. Move to higher levels only when needed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
