Validate Dependencies Skill (L9-L12)

BlueMouse 17-Layer Validation System - Group 3: 依賴關係驗證

Two Ways to Use

1. AI-Guided Validation

Follow the checklist below to analyze code.

2. Script Execution

python3 .claude/skills/validate-dependencies/validator.py myfile.py
python3 .claude/skills/validate-dependencies/validator.py --verbose myfile.py

L9-L12 Validation Checklist

L9: 導入檢查 (Informational)

What: Count import statements in code

How:

imports = [
    node for node in ast.walk(tree)
    if isinstance(node, (ast.Import, ast.ImportFrom))
]

Output: "找到 N 個導入語句" Pass: Always (informational only)

L10: 標準庫檢查 (Informational)

What: Identify Python standard library usage

Known Stdlib:

stdlib = {
    'os', 'sys', 'json', 're', 'datetime', 'typing',
    'asyncio', 'time', 'math', 'hashlib', 'collections',
    'functools', 'itertools', 'pathlib', 'subprocess',
    'threading', 'multiprocessing', 'logging', 'unittest',
    'argparse', 'copy', 'io', 'tempfile'
}

How:

import_names = []
for node in ast.walk(tree):
    if isinstance(node, ast.Import):
        for n in node.names:
            import_names.append(n.name.split('.')[0])
    elif isinstance(node, ast.ImportFrom):
        if node.module:
            import_names.append(node.module.split('.')[0])

used = [name for name in import_names if name in stdlib]

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

L11: 第三方庫檢查 (Informational)

What: Identify common third-party library usage

Known Third-Party:

third_party = {
    'django', 'flask', 'fastapi', 'requests', 'numpy',
    'pandas', 'pytest', 'aiohttp', 'sqlalchemy', 'pydantic',
    'httpx', 'redis', 'celery', 'boto3', 'tensorflow',
    'torch', 'scikit-learn'
}

How:

used = []
for module in third_party:
    if f"import {module}" in code or f"from {module}" in code:
        used.append(module)

Output:

• Found: "使用了 N 個第三方庫"
• None: "未使用第三方庫"

Pass: Always (informational only)

L12: 循環依賴檢查 ⚠️

What: Detect risky relative imports that may cause circular dependencies

How:

for node in ast.walk(tree):
    if isinstance(node, ast.ImportFrom) and node.level > 0:
        has_relative = True

Import Level Explanation:

Pass: No relative imports → "通過 (未檢測到危險的相對導入)" Fail: "檢測到相對導入，可能存在循環依賴風險"

Examples:

# ✅ PASS: Absolute imports only
import os
from package.module import func
from typing import Dict

# ❌ FAIL: Relative imports
from .sibling import helper  # level=1
from ..parent import config  # level=2

Why Relative Imports Are Risky:

project/
├── package_a/
│   └── module_a.py  # from ..package_b import func_b
└── package_b/
    └── module_b.py  # from ..package_a import func_a
                     # ❌ Circular dependency!
