Exploration Protocol

Phase 1: Initial Reconnaissance

# List root files
ls -la

# Find config files
find . -maxdepth 2 -name "package.json" -o -name "*.config.*" -o -name "pyproject.toml" -o -name "go.mod" -o -name "Cargo.toml" 2>/dev/null

# Check for common entry points
ls -la src/ app/ lib/ cmd/ 2>/dev/null

Phase 2: Structure Mapping

# Tree view (excluding common noise)
tree -L 3 -I 'node_modules|dist|build|.git|__pycache__|.next|target|vendor' 2>/dev/null || find . -type d -maxdepth 3 | head -50

# Identify main directories
ls -la src/ lib/ app/ internal/ pkg/ 2>/dev/null

Phase 3: Entry Points Detection

# JavaScript/TypeScript
grep -rn "main\|index\|app.listen\|createServer\|export default" --include="*.{js,ts,jsx,tsx}" | head -20

# Python
grep -rn "if __name__\|main()\|app.run\|uvicorn" --include="*.py" | head -20

# Go
grep -rn "func main\|http.ListenAndServe" --include="*.go" | head -20

# Rust
grep -rn "fn main" --include="*.rs" | head -10

Phase 4: Dependency Analysis

# Node.js
cat package.json 2>/dev/null | head -50

# Python
cat pyproject.toml requirements.txt setup.py 2>/dev/null | head -50

# Go
cat go.mod 2>/dev/null

# Rust
cat Cargo.toml 2>/dev/null | head -50

# PHP
cat composer.json 2>/dev/null | head -50

Phase 5: Pattern Detection

Search for architectural patterns:

# MVC patterns
ls -la controllers/ models/ views/ routes/ 2>/dev/null

# Clean/Hexagonal Architecture
ls -la domain/ application/ infrastructure/ interfaces/ adapters/ ports/ 2>/dev/null

# Feature-based
ls -la features/ modules/ 2>/dev/null

# Next.js App Router
ls -la app/ pages/ components/ 2>/dev/null

Architecture Pattern Detection

Pattern Indicators

Tech Stack Detection

JavaScript/TypeScript

Detection commands:

# Framework detection
grep -l "next\|react\|vue\|angular\|svelte" package.json 2>/dev/null

# Database/ORM
ls prisma/ drizzle/ migrations/ 2>/dev/null

# State management
grep -E "zustand|redux|@reduxjs|jotai|recoil" package.json 2>/dev/null

Python

Detection commands:

# Framework detection
grep -E "django|flask|fastapi|starlette" pyproject.toml requirements.txt 2>/dev/null

# ORM
grep -E "sqlalchemy|django|tortoise|peewee" pyproject.toml requirements.txt 2>/dev/null

Go

Detection commands:

# Framework detection
grep -E "gin|echo|fiber|chi|gorilla" go.mod 2>/dev/null

# Database
grep -E "gorm|sqlx|ent|pgx" go.mod 2>/dev/null

PHP

Rust

Code Organization Assessment

Check Interface Separation

# TypeScript/JavaScript
ls -la src/interfaces/ src/types/ types/ 2>/dev/null

# Check for interfaces in components (violation)
grep -r "interface.*Props\|type.*Props" --include="*.tsx" src/components/ 2>/dev/null | head -10

Check Business Logic Location

# Hooks for business logic
ls -la src/hooks/ hooks/ 2>/dev/null

# Check for logic in components (violation)
grep -rn "useState\|useEffect\|async" --include="*.tsx" src/components/ 2>/dev/null | wc -l

Check State Management

# Store files
ls -la src/stores/ stores/ src/store/ 2>/dev/null

# Store usage
grep -r "useStore\|useSelector\|create(" --include="*.{ts,tsx}" src/ 2>/dev/null | head -10

Quick Analysis Commands

Full Stack Assessment

# One-liner for quick assessment
echo "=== Package Manager ===" && ls package.json pyproject.toml go.mod Cargo.toml composer.json 2>/dev/null && echo "=== Framework ===" && head -20 package.json 2>/dev/null | grep -E "next|react|vue|express" && echo "=== Structure ===" && ls -la src/ app/ lib/ 2>/dev/null

File Count by Type

# Count files by extension
find . -type f -name "*.ts" -o -name "*.tsx" -o -name "*.js" -o -name "*.jsx" 2>/dev/null | wc -l
find . -type f -name "*.py" 2>/dev/null | wc -l
find . -type f -name "*.go" 2>/dev/null | wc -l

Large Files Detection

# Find files > 100 lines (potential violations)
find . -name "*.ts" -o -name "*.tsx" -o -name "*.py" 2>/dev/null | xargs wc -l 2>/dev/null | sort -rn | head -20
