SOLID Detection Skill

Project Detection

Detect project type from configuration files:

# 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

Rule	Value
File limit	150 lines
Interface location	modules/cores/interfaces/
Forbidden	Interfaces in components/, app/

Pattern detection:

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

Laravel / PHP

Rule	Value
File limit	100 lines
Interface location	app/Contracts/
Forbidden	Interfaces outside Contracts

Pattern detection:

^interface \w+

Swift

Rule	Value
File limit	150 lines
Interface location	Protocols/
Forbidden	Protocols outside Protocols/

Pattern detection:

^protocol \w+

Go

Rule	Value
File limit	100 lines
Interface location	internal/interfaces/
Forbidden	Interfaces outside interfaces/

Pattern detection:

^type \w+ interface \{

Python

Rule	Value
File limit	100 lines
Interface location	src/interfaces/
Forbidden	ABC outside interfaces/

Pattern detection:

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

Rust

Rule	Value
File limit	100 lines
Interface location	src/traits/
Forbidden	Traits outside traits/

Pattern detection:

^pub trait \w+

Line Counting

Exclude from count:

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

# 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

Validation Actions

Severity	Action
Interface in wrong location	BLOCK (exit 2)
File over limit	WARNING (exit 0)
Missing documentation	WARNING
