nsforge-mcp: Skill for Claude Code

.claude/skills/code-refactor/SKILL.md

code-refactor is a skill for Claude Code from u9401066/nsforge-mcp. It costs 0 tokens per session (2,401 once invoked), scanned A, original, Apache-2.0.

A code-refactoring skill that helps reorganize code into smaller, clearer parts while following domain-driven design, an approach that structures software around business concepts.

In plain words
What is it for?
Use it to split long functions, extract reusable methods, reduce nesting and dependencies, and keep the project structure manageable.
Why use it?
It identifies oversized or overly complex files, classes, functions, folders, and dependencies before they become harder to maintain.

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

code-refactor 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.

程式碼重構技能

描述

主動偵測並執行程式碼重構,維持 DDD 架構和程式碼品質。

觸發條件

  • 「重構這段程式碼」、「refactor」
  • 「這個檔案太長了」
  • 「模組化」、「拆分」
  • 主動觸發:偵測到程式碼超過閾值時

核心原則

📜 依據憲法第 7.3 條「主動重構原則」

重構不是改天換地,而是持續的小步快跑
每次提交都應該比上次更乾淨

閾值設定

📏 長度閾值

類型 警告 強制重構
檔案 > 200 行 > 400 行
類別 > 150 行 > 300 行
函數 > 30 行 > 50 行
目錄檔案數 > 10 個 > 15 個

🔄 複雜度閾值

指標 警告 強制重構
圈複雜度 > 10 > 15
巢狀深度 > 3 層 > 4 層
參數數量 > 4 個 > 6 個
依賴數量 > 5 個 > 8 個

重構模式庫

1️⃣ Extract Method(提取方法)

觸發條件:函數過長、重複邏輯

# Before
def process_order(order):
    # 驗證訂單 (10 行)
    if not order.items:
        raise ValueError("Empty order")
    if order.total < 0:
        raise ValueError("Invalid total")
    # ... 更多驗證
    
    # 計算價格 (15 行)
    subtotal = sum(item.price * item.qty for item in order.items)
    tax = subtotal * 0.05
    total = subtotal + tax
    # ... 更多計算
    
    # 儲存訂單 (10 行)
    # ...

# After
def process_order(order):
    self._validate_order(order)
    total = self._calculate_total(order)
    self._save_order(order, total)

def _validate_order(self, order):
    """驗證訂單有效性"""
    if not order.items:
        raise ValueError("Empty order")
    # ...

def _calculate_total(self, order) -> Decimal:
    """計算訂單總金額(含稅)"""
    subtotal = sum(item.price * item.qty for item in order.items)
    return subtotal * Decimal("1.05")

2️⃣ Extract Class(提取類別)

觸發條件:類別職責過多、超過 150 行

# Before: User 類別包含太多職責
class User:
    def __init__(self, name, email, ...):
        self.name = name
        self.email = email
        self.address_line1 = ...
        self.address_line2 = ...
        self.city = ...
        self.postal_code = ...
    
    def validate_email(self): ...
    def format_address(self): ...
    def calculate_shipping(self): ...

# After: 提取 Address 值物件
@dataclass(frozen=True)
class Address:
    """地址值物件"""
    line1: str
    line2: str | None
    city: str
    postal_code: str
    
    def format(self) -> str:
        return f"{self.line1}\n{self.city} {self.postal_code}"

class User:
    def __init__(self, name: str, email: Email, address: Address):
        self.name = name
        self.email = email
        self.address = address

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.
