}

Use Cases

Enterprise Development Team

Scenario: Large development team with strict security and compliance requirements.

Implementation:

# Initial setup
mret init
mret hooks install
mret completion install

# Security baseline
mret env encrypt
mret secrets scan
mret audit check --level high
mret license --allowed MIT,Apache-2.0

# Quality gates
mret coverage --threshold 90
mret bundle check --max-size 500

# CI/CD pipeline testing
mret act validate

Open Source Project

Scenario: Public repository requiring automated changelog and contribution guidelines.

Implementation:

# Setup contribution workflow
mret gitignore --templates node,vscode,macos
mret hooks install

# Generate documentation
mret changelog
mret license

# Quality checks
mret audit check
mret secrets scan

Microservices Architecture

Scenario: Multiple services with independent deployment pipelines.

Implementation:

# Per-service commands in mret.config.js
module.exports = {
  'service:user:build': 'cd services/user && npm run build',
  'service:user:test': 'cd services/user && npm test',
  'service:user:deploy': 'cd services/user && firebase deploy --only functions:user',
  
  'service:api:build': 'cd services/api && npm run build',
  'service:api:test': 'cd services/api && npm test',
  'service:api:deploy': 'cd services/api && firebase deploy --only functions:api'
};

Best Practices

Environment Management

DO:

• Always encrypt production secrets
• Use environment-specific files (.env.dev, .env.prod)
• Maintain backups before switching environments
• Regular secret rotation

DON'T:

• Commit unencrypted .env files
• Share encryption passwords via insecure channels
• Use same secrets across environments

Security Scanning

Recommended Workflow:

# Pre-commit
mret secrets scan
mret audit check --level high

# Pre-deployment
mret bundle check
mret coverage --threshold 80
mret license

CI/CD Integration

GitHub Actions Example:

name: Quality Gates
on: [push, pull_request]
jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
      - run: npm install -g mret
      - run: mret secrets scan
      - run: mret audit check --level moderate
      - run: mret license --allowed MIT,Apache-2.0,MIT
      - run: mret coverage --threshold 80

Git Workflow

Recommended:

# Before commit
mret git commit  # Use conventional commits

# Regular maintenance
mret git cleanup

# Release preparation
mret changelog

Architecture

Plugin System

mret uses a modular architecture with independent command modules:

src/
├── commands/          # Command implementations
│   ├── security/     # Security-related commands
│   ├── testing/      # Testing and QA commands
│   ├── build/        # Build and deployment
│   └── git/          # Git utilities
├── utils/            # Shared utilities
│   ├── encryption.ts # Cryptography functions
│   ├── firebase.ts   # Firebase integration
│   └── loader.ts     # Configuration loading
└── index.ts          # CLI entry point

Extension Points

Custom commands can be added via:

1. Configuration File: mret.config.js
2. Alias System: mret alias create
3. Plugin System: (Planned for v2.0)

Security

Encryption Specification

Algorithm: AES-256-CBC
Key Derivation: PBKDF2
Iterations: 10,000
Salt Length: 16 bytes
IV Length: 16 bytes

Secret Detection Patterns

Regular expression patterns for common secret types are maintained in src/commands/secrets.ts. Custom patterns can be added by extending the SECRET_PATTERNS array.

Data Privacy

• All encrypted data remains local
• No telemetry or analytics collection
• Firebase integration is optional and user-controlled
• No external API calls without explicit user action

Privacy & Security

Privacy-First Design

mret is built with privacy as a core principle:

• Zero Telemetry: No analytics, tracking, or data collection
• Local-First: All operations performed on your machine
• No Cloud Dependencies: Works completely offline (except optional features)
• Transparent: Open source with auditable code

Data Handling

What We DON'T Collect:

• Personal information
• Usage statistics
• System information
• File contents
• IP addresses
• Any identifiable data

What Stays Local:

• Configuration files (~/.mretconfig)
• Encrypted environment files
• Command aliases
• All project data

Optional Cloud Features

Firebase Integration (Optional):

• Requires explicit setup: mret config setup
• Only used for mret world commands
• You control what data to publish
• Can be deleted anytime: mret world delete

Compliance

mret complies with major data protection regulations:

• GDPR (EU): Privacy by design, local data processing
• DPDP (India): Explicit consent, user data control
• CCPA (California): No data sales, user rights respected
• PIPEDA (Canada): Transparent data practices

Full Details: See PRIVACY.md

Security Features

Encryption:

• Algorithm: AES-256-CBC
• Key Derivation: PBKDF2 (10,000 iterations)
• Industry-standard implementation

Secret Detection:

• Pattern-based scanning for exposed credentials
• No data transmission
• Local analysis only

Vulnerability Management:

• Integrated with npm/yarn/pnpm audits
• Severity-based filtering
• Automated remediation

Responsible Disclosure:

• Security issues: mreshanktyagi@gmail.com
• See SECURITY.md for details

Performance

Benchmarks

Command execution times (approximate):

Command	Duration	Notes
mret env encrypt	< 100ms	Depends on file size
mret secrets scan	1-3s	Depends on project size
mret audit check	2-5s	Network dependent
mret bundle analyze	Varies	Depends on build time
mret git cleanup	< 500ms	Local operation

Optimization Tips

• Use --exclude patterns for faster scanning
• Enable caching for repeated operations
• Run expensive operations (bundle analysis) in dedicated CI steps
