# PCAP Network Analysis Guide

This skill provides guidance for analyzing network packet captures (PCAP files) and computing network statistics using Python.

## Quick Start: Using the Helper Module

A utility module (`pcap_utils.py`) is available in this folder with **tested, correct implementations** of common analysis functions. It provides some utility functions to count intermediate results and help you come to some of the conclusion faster. **Use these functions directly** rather than reimplementing the logic yourself, as they handle edge cases correctly.

```python
# RECOMMENDED: Import and use the helper functions
import sys
sys.path.insert(0, '/root/skills/pcap-analysis')  # Add skill folder to path
from pcap_utils import (
    load_packets, split_by_protocol, graph_metrics,
