BlueMouse 17-Layer Validation Skill

Complete code validation system from the BlueMouse AI Safety project. Validates Python code across 17 dimensions.

Two Ways to Use

1. AI-Guided Validation (Recommended)

When user requests code validation, follow the 17-Layer Checklist below to analyze the code.

2. Script Execution

Copypython3 .claude/skills/validate-17-layers/validator.py myfile.py
python3 .claude/skills/validate-17-layers/validator.py --json myfile.py

17-Layer Validation Checklist

When validating Python code, check ALL 17 layers in order:

Group 1: L1-L4 語法和結構驗證

L1: 基本語法檢查

What: Code compiles without syntax errors How: compile(code, '<string>', 'exec') Pass: No SyntaxError Fail: Report syntax error location and message

L2: AST 結構檢查

What: Code contains function or class definitions How: Parse AST, check for FunctionDef or ClassDef nodes Pass: At least one function or class defined Fail: "缺少函數或類定義"

L3: 縮進和格式檢查

What: Proper indentation How: Check each line:

• No tab characters (\t)
• Leading spaces are multiples of 4 Pass: All lines follow rules Fail: Report lines with issues (max 3)

L4: 命名規範檢查

What: PEP 8 naming conventions How:

• Functions: ^[a-z_][a-z0-9_]*$ (snake_case)
• Classes: ^[A-Z][a-zA-Z0-9]*$ (PascalCase) Pass: All names follow conventions Fail: Report non-compliant names

---

Group 2: L5-L8 函數簽名驗證

L5: 參數檢查

What: Function has parameters (or matches spec if provided) How: Extract function arguments from AST Pass: Has parameters or matches spec Fail: "參數不匹配" with expected vs actual

L6: 返回值檢查

What: Function has explicit return statement How: Check for ast.Return nodes in function body Pass: Has at least one return Fail: "函數缺少返回值"

L7: 類型提示檢查

What: Type hints coverage ≥80% and has return type How:

Copycoverage = params_with_annotations / total_params
passed = coverage >= 0.8 AND has_return_type_hint

Pass: Coverage ≥80% with return type Fail: "類型提示不足: X%"

L8: 文檔字符串檢查

What: Meaningful docstring (>10 characters) How: ast.get_docstring(func) Pass: Docstring length > 10 Fail: "缺少或文檔字符串過短"

---

Group 3: L9-L12 依賴關係驗證

L9: 導入檢查

What: Count import statements How: Count ast.Import and ast.ImportFrom nodes Pass: Always (informational) Output: "找到 N 個導入語句"

L10: 標準庫檢查

What: Identify stdlib usage How: Match imports against known stdlib:

Copy{os, sys, json, re, datetime, typing, asyncio, time, math, hashlib}

Pass: Always (informational) Output: "精確識別出 N 個標準庫導入"

L11: 第三方庫檢查

What: Identify third-party library usage How: Match imports against common packages:

Copy{django, flask, fastapi, requests, numpy, pandas}

Pass: Always (informational) Output: "使用了 N 個第三方庫"

L12: 循環依賴檢查

What: Detect risky relative imports How: Check ast.ImportFrom nodes where level > 0

Copyfrom ..module import x  # level=2, RISKY
from .sibling import y  # level=1, RISKY

Pass: No relative imports Fail: "檢測到相對導入，可能存在循環依賴風險"

---

Group 4: L13-L17 類型和邏輯驗證

L13: 類型一致性檢查

What: All functions have ≥70% type hint coverage How: Scan all functions, calculate overall coverage Pass: Coverage ≥70% Fail: "函數類型提示覆蓋率: X%"

L14: 邏輯完整性檢查

What: Code has control flow structures How: Check for ast.If, ast.For, ast.While Pass: Always (informational) Output: "邏輯結構完整" or "邏輯結構簡單"

L15: 錯誤處理檢查 ⚠️ ANTI-PATTERN DETECTION

What: No empty try-except blocks How: Find ast.Try nodes, check handlers:

Copy# ❌ FAIL: Empty handler
except:
    pass

# ❌ FAIL: Only pass
except Exception as e:
    pass

# ✅ PASS: Actual handling
except Exception as e:
    logger.error(e)
    raise

Pass: Has try-except AND no empty/pass-only handlers Fail: "發現 N 個空的或只有 pass 的錯誤處理塊 (Anti-pattern)"

L16: 安全性檢查 🔒 SECURITY SCAN

What: No dangerous functions or hardcoded secrets How:

1. Dangerous functions:
   • eval() - arbitrary code execution
   • exec() - arbitrary code execution
   • pickle - deserialization vulnerability
2. Hardcoded secrets (regex):
   • api_key\s*=\s*[\'"][^\s*]{10,}[\'"]
   • password\s*=\s*[\'"][^\s*]{8,}[\'"] Pass: No dangerous functions AND no hardcoded secrets Fail: "發現 N 個潛在安全性問題" with list

L17: 性能檢查 ⚡ COMPLEXITY ANALYSIS

What: No deeply nested loops (≥3 levels) How: Calculate maximum loop nesting depth

Copy# ❌ FAIL: 3-level nesting
for i in range(n):      # Level 1
    for j in range(n):  # Level 2
        for k in range(n):  # Level 3 - TOO DEEP
            pass

# ✅ PASS: 2-level nesting
for i in range(n):      # Level 1
    for j in range(n):  # Level 2
        pass

Pass: max_depth < 3 Fail: "檢測到過深的循環嵌套 (Depth: N)，建議優化算法"
