"set up FastAPI with React"
"analyze code quality"
"check for security issues in codebase"
"what stack should I use"
"set up a fullstack project"

fastapi-react - FastAPI backend + React frontend + PostgreSQL
mern - MongoDB, Express, React, Node.js with TypeScript
django-react - Django REST Framework + React frontend

Usage:

# List available templates
python scripts/project_scaffolder.py --list-templates

# Create Next.js project
python scripts/project_scaffolder.py nextjs my-app

# Create FastAPI + React project
python scripts/project_scaffolder.py fastapi-react my-api

# Create MERN stack project
python scripts/project_scaffolder.py mern my-project

# Create Django + React project
python scripts/project_scaffolder.py django-react my-app

# Specify output directory
python scripts/project_scaffolder.py nextjs my-app --output ./projects

# JSON output
python scripts/project_scaffolder.py nextjs my-app --json

Parameters:

Parameter	Description
`template`	Template name (nextjs, fastapi-react, mern, django-react)
`project_name`	Name for the new project directory
`--output, -o`	Output directory (default: current directory)
`--list-templates, -l`	List all available templates
`--json`	Output in JSON format

Output includes:

Project structure with all necessary files
Package configurations (package.json, requirements.txt)
TypeScript configuration
Docker and docker-compose setup
Environment file templates
Next steps for running the project

Code Quality Analyzer

Analyzes fullstack codebases for quality issues.

Analysis Categories:

Security vulnerabilities (hardcoded secrets, injection risks)
Code complexity metrics (cyclomatic complexity, nesting depth)
Dependency health (outdated packages, known CVEs)
Test coverage estimation
Documentation quality

Usage:

# Analyze current directory
python scripts/code_quality_analyzer.py .

# Analyze specific project
python scripts/code_quality_analyzer.py /path/to/project

# Verbose output with detailed findings
python scripts/code_quality_analyzer.py . --verbose

# JSON output
python scripts/code_quality_analyzer.py . --json

# Save report to file
python scripts/code_quality_analyzer.py . --output report.json

Parameters:

Parameter	Description
`project_path`	Path to project directory (default: current directory)
`--verbose, -v`	Show detailed findings
`--json`	Output in JSON format
`--output, -o`	Write report to file

Output includes:

Overall score (0-100) with letter grade
Security issues by severity (critical, high, medium, low)
High complexity files
Vulnerable dependencies with CVE references
Test coverage estimate
Documentation completeness
Prioritized recommendations

Workflows

Workflow 1: Start New Project

Choose appropriate stack based on requirements (see Stack Decision Matrix)
Scaffold project structure
Verify scaffold: confirm package.json (or requirements.txt) exists
Run initial quality check — address any P0 issues before proceeding
Set up development environment

# 1. Scaffold project
python scripts/project_scaffolder.py nextjs my-saas-app

# 2. Verify scaffold succeeded
ls my-saas-app/package.json

# 3. Navigate and install
cd my-saas-app
npm install

# 4. Configure environment
cp .env.example .env.local

# 5. Run quality check
python ../scripts/code_quality_analyzer.py .

# 6. Start development
npm run dev

Workflow 2: Audit Existing Codebase

Run code quality analysis
Review security findings — fix all P0 (critical) issues immediately
Re-run analyzer to confirm P0 issues are resolved
Create tickets for P1/P2 issues

# 1. Full analysis
python scripts/code_quality_analyzer.py /path/to/project --verbose

# 2. Generate detailed report
python scripts/code_quality_analyzer.py /path/to/project --json --output audit.json

# 3. After fixing P0 issues, re-run to verify
python scripts/code_quality_analyzer.py /path/to/project --verbose

Workflow 3: Stack Selection

Use the tech stack guide to evaluate options:

SEO Required? → Next.js with SSR
API-heavy backend? → Separate FastAPI or NestJS
Real-time features? → Add WebSocket layer
Team expertise → Match stack to team skills

See references/tech_stack_guide.md for detailed comparison.

Quick Reference

Stack Decision Matrix

Requirement	Recommendation
SEO-critical site	Next.js with SSR
Internal dashboard	React + Vite
API-first backend	FastAPI or Fastify
Enterprise scale	NestJS + PostgreSQL
Rapid prototype	Next.js API routes
Document-heavy data	MongoDB
Complex queries	PostgreSQL

Common Issues

Issue	Solution
N+1 queries	Use DataLoader or eager loading
Slow builds	Check bundle size, lazy load
Auth complexity	Use Auth.js or Clerk
Type errors	Enable strict mode in tsconfig
CORS issues	Configure middleware properly
