SOLID Detection Skill

Project Detection

Detect project type from configuration files:

# Next.js (priority over React)
[ -f "package.json" ] && grep -q '"next"' package.json

# React (no "next" in package.json)
[ -f "package.json" ] && grep -q '"react"' package.json && ! grep -q '"next"' package.json

# Generic TypeScript (no react/next, has .ts files)
[ -f "package.json" ] && ! grep -q '"react"' package.json && ! grep -q '"next"' package.json
[ -f "tsconfig.json" ] || [ -f "bun.lockb" ] || [ -f "bunfig.toml" ]

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

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

# Java
[ -f "pom.xml" ] || [ -f "build.gradle" ] || [ -f "build.gradle.kts" ]

# Go
[ -f "go.mod" ]

# Ruby
[ -f "Gemfile" ] && [ -f "Rakefile" ]

# Rust
[ -f "Cargo.toml" ]

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

Priority order: Next.js > React > Generic TS > Laravel > Swift > Java > Go > Ruby > Rust > Python

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

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

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
