SOLID Detection Skill

Project Detection

Detect project type from configuration files:

Copy# Next.js
[ -f "package.json" ] && grep -q '"next"' package.json

# Laravel
[ -f "composer.json" ] && grep -q '"laravel' composer.json

# Swift
[ -f "Package.swift" ] || ls *.xcodeproj

# Go
[ -f "go.mod" ]

# Rust
[ -f "Cargo.toml" ]

# Python
[ -f "pyproject.toml" ] || [ -f "requirements.txt" ]

Language Rules

Next.js / TypeScript

Pattern detection:

Copy^(export )?(interface|type) \w+

Laravel / PHP

Pattern detection:

Copy^interface \w+

Swift

Pattern detection:

Copy^protocol \w+

Go

Pattern detection:

Copy^type \w+ interface \{

Python

Pattern detection:

Copyclass \w+\(.*ABC.*\)

Rust

Pattern detection:

Copy^pub trait \w+

Line Counting

Exclude from count:

• Blank lines
• Comments (//, /* */, #, """)
• Import statements (optional)

Copy# TypeScript/Go/Rust/Swift
grep -v '^\s*$\|^\s*//\|^\s*/\*\|^\s*\*' file

# PHP
grep -v '^\s*$\|^\s*//\|^\s*#\|^\s*/\*\|^\s*\*' file

# Python
grep -v '^\s*$\|^\s*#\|^\s*"""' file
