<objective> SOLID Detection identifies a project's language/framework from its config files (package.json + next/react, tsconfig.json/bun files, composer.json + laravel, Package.swift/*.xcodeproj, pom.xml/build.gradle, go.mod, Gemfile+Rakefile, Cargo.toml, pyproject.toml/requirements.txt) in a fixed priority order, then maps it to the matching SOLID skill and sets SOLIDPROJECTTYPE, SOLIDFILELIMIT, SOLIDINTERFACEDIR, and SOLID_STRUCTURE environment variables via detect-project.sh.

An interface found in the wrong location is a hard BLOCK; exceeding the file-size limit or missing documentation is a WARNING only. See language-rules.md for the full per-language interface-location, forbidden-zone, and line-counting rules. </objective>

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
