📦 mathematical audit skills — 技能工具

version: 3.5.4 | Read-Only File Access, No Network Access, No Dynamic Execution

Description

A mathematical depth audit tool for OpenClaw skills and code. Provides mathematical quality assessment based on complexity analysis, pattern recognition, entropy analysis, and structural analysis.

Security Guarantees - Verified

• ✅ Read-Only File Access: Reads target files for analysis only, no writes or modifications
• ✅ No Network Access: Completely offline processing, no HTTP/HTTPS calls
• ✅ No Dynamic Code Execution: 100% static analysis only, no eval/exec/compile
• ✅ No Background Processes: Runs only when explicitly called, no daemon
• ✅ No Subprocess Calls: No shell execution, no external process spawning
• ✅ No External Dependencies: Pure Python, no requests/numpy/scipy required

What This Skill Does

• Mathematical Complexity Analysis: Measures code complexity using Shannon entropy
• Pattern Recognition: Detects functions, classes, imports, and comments
• Structural Analysis: Analyzes indentation patterns and nesting depth
• Statistical Analysis: Performs statistical analysis of code metrics
• Quality Assessment: Provides overall quality score and certification rate

What This Skill Does NOT Do

❌ No file writes or modifications - Cannot modify any files (read-only) ❌ No network calls - Cannot access localhost or any network ❌ No dynamic execution - Cannot execute any code (no eval/exec/compile) ❌ No background processes - No daemon, no monitoring, no services ❌ No subprocess calls - No shell execution, no external processes ❌ No external dependencies - No requests, numpy, scipy, etc.

Usage

# Install the skill
openclaw skill install mathematical-audit
# Run audit on a target
openclaw skill run mathematical-audit --target /path/to/skill
# Or use directly
python skill.py /path/to/target

Output Format

The skill returns a JSON report with:

• Overall score (0.000 to 1.000)
• Quality level (poor/fair/good/excellent)
• Certification rate (percentage)
• Detailed analysis per file
• Statistical summary

Security Verification

File Access Clarification:

• Only reads - never writes or modifies files
• Read-only access - uses open(file, 'r') not open(file, 'w')
• Temporary access - files are read, analyzed, then closed

How to Verify Security:

1. Quick Command Line Checks:

# Check for network access
grep -r "import requests\|import urllib\|import http\|import socket\|http://\|https://" skill.py
# Check for dynamic execution
grep -r "eval(\|exec(\|compile(\|__import__" skill.py
# Check for subprocess calls
grep -r "import subprocess\|subprocess\.\|os\.system\|shell=True" skill.py
# Check for file writes
grep -r "open(.'w'\|open(.\"w\"" skill.py

2. Bandit Security Scan:

pip install bandit
bandit -r .

3. Manual Python Verification:

#!/usr/bin/env python3
import sys
def check_security():
    with open('skill.py', 'r') as f:
        content = f.read()
    
    issues = []
    
    # Check patterns
    checks = [
        ("Network", ["requests", "urllib", "http.client", "socket"]),
        ("Dynamic", ["eval(", "exec(", "compile(", "__import__("]),
        ("Subprocess", ["subprocess", "os.system", "shell=True"]),
        ("File writes", ["open(", "'w'", '"w"', "'wb'", '"wb"']),
    ]
    
    for check_name, patterns in checks:
        for pattern in patterns:
            if pattern in content:
                issues.append(f"{check_name}: {pattern}")
    
    if issues:
        print("Security issues found:")
        for issue in issues:
            print(f"  - {issue}")
        return False
    else:
        print("All security checks passed")
        return True
if __name__ == "__main__":
    if check_security():
        sys.exit(0)
    else:
        sys.exit(1)

Expected Results:

• Command line checks: No output (no matches found)
• Bandit scan: No issues identified
• Manual verification: All checks passed
