fusengine 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

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 |
