# Soil Classification Tool Skill

## Purpose

The Soil Classification Tool Skill classifies soils using USCS and AASHTO systems, interprets Atterberg limits, and provides SPT correlation calculations for engineering properties.

## Capabilities

- USCS classification
- AASHTO soil classification
- Atterberg limits interpretation
- Grain size distribution analysis
- Soil description generator
- SPT correlation calculations
- Relative density estimation
- Consistency determination

## Usage Guidelines

### When to Use
