+ {processedData.map(item => ( + onUpdate(id)} /> // New function every render + ))} +
+ ); +} +``` + +### Backend Performance + +**Async/Await Best Practices**: +```csharp +// GOOD: Proper async implementation +public async Task> GetUser(int id, CancellationToken ct) +{ + var user = await _db.Users + .AsNoTracking() // Read-only queries + .FirstOrDefaultAsync(u => u.Id == id, ct); + + if (user == null) + return NotFound(); + + return Ok(user); +} + +// BAD: Blocking async code +public async Task> GetUserBad(int id) +{ + var user = _db.Users.FirstOrDefault(u => u.Id == id); // Blocking! + return Ok(user); +} +``` + +**Caching Strategy**: +```javascript +// GOOD: Redis caching with TTL +const redis = require('redis'); +const client = redis.createClient(); + +async function getCachedData(key, fetchFunction, ttl = 3600) { + // Try cache first + const cached = await client.get(key); + if (cached) return JSON.parse(cached); + + // Fetch and cache + const data = await fetchFunction(); + await client.setex(key, ttl, JSON.stringify(data)); + + return data; +} + +// Usage +const userData = await getCachedData( + `user:${userId}`, + () => db.users.findById(userId), + 3600 // 1 hour TTL +); +``` + +### Database Performance + +**Query Optimization**: +```sql +-- GOOD: Indexed query with specific columns +CREATE INDEX idx_users_email ON users(email); + +SELECT id, name, email +FROM users +WHERE email = $1; + +-- BAD: Full table scan +SELECT * FROM users WHERE LOWER(email) = LOWER($1); +``` + +**N+1 Prevention**: +```javascript +// GOOD: Eager loading with joins +const posts = await db.posts.findAll({ + include: [{ + model: db.users, + attributes: ['id', 'name'] + }] +}); + +// BAD: N+1 query problem +const posts = await db.posts.findAll(); +for (const post of posts) { + post.author = await db.users.findById(post.authorId); // N queries! +} +``` + +### Performance Checklist + +- [ ] Profile before optimizing (Chrome DevTools, Lighthouse) +- [ ] Minimize bundle size (tree-shaking, code splitting) +- [ ] Optimize images (WebP, AVIF, lazy loading) +- [ ] Use CDN for static assets +- [ ] Enable HTTP/2 or HTTP/3 +- [ ] Implement caching strategy +- [ ] Monitor Core Web Vitals (LCP, FID, CLS) + +## 4. Object Calisthenics (Domain Code) + +### 9 Rules for Clean Domain Code + +#### Rule 1: One Level of Indentation + +```csharp +// GOOD: Extract methods +public void SendNewsletter() +{ + var activeUsers = users.Where(u => u.IsActive); + foreach (var user in activeUsers) + { + SendEmail(user); + } +} + +private void SendEmail(User user) +{ + _mailer.Send(user.Email); +} + +// BAD: Multiple indentation levels +public void SendNewsletter() +{ + foreach (var user in users) + { + if (user.IsActive) + { + if (user.Email != null) + { + _mailer.Send(user.Email); + } + } + } +} +``` + +#### Rule 2: No ELSE Keyword (Guard Clauses) + +```csharp +// GOOD: Early returns +public void ProcessOrder(Order order) +{ + if (order == null) throw new ArgumentNullException(nameof(order)); + if (!order.IsValid) throw new InvalidOperationException("Invalid order"); + + // Process order +} + +// BAD: Else keyword +public void ProcessOrder(Order order) +{ + if (order.IsValid) + { + // Process order + } + else + { + throw new InvalidOperationException("Invalid order"); + } +} +``` + +#### Rule 3: Wrap Primitives + +```csharp +// GOOD: Value objects +public class Email +{ + private readonly string _value; + + public Email(string value) + { + if (!IsValid(value)) + throw new ArgumentException("Invalid email"); + _value = value; + } + + private static bool IsValid(string email) => + Regex.IsMatch(email, @"^[^@\s]+@[^@\s]+\.[^@\s]+$"); + + public override string ToString() => _value; +} + +// Usage +public class User +{ + public Email Email { get; private set; } +} + +// BAD: Raw primitives +public class User +{ + public string Email { get; set; } // No validation +} +``` + +#### Rule 4: First Class Collections + +```csharp +// GOOD: Collection wrapper +public class UserCollection +{ + private readonly List _users = new(); + + public void Add(User user) + { + if (_users.Any(u => u.Email == user.Email)) + throw new InvalidOperationException("User already exists"); + _users.Add(user); + } + + public IEnumerable GetActive() => + _users.Where(u => u.IsActive); + + public int Count => _users.Count; +} + +// BAD: Exposed list +public class Group +{ + public List Users { get; set; } // Exposed mutable collection +} +``` + +#### Rule 5: One Dot Per Line + +```csharp +// GOOD: Intermediate variables +public void ProcessOrder(Order order) +{ + var user = order.User; + var email = user.GetEmail(); + var upperEmail = email.ToUpper(); + SendConfirmation(upperEmail); +} + +// BAD: Method chaining +public void ProcessOrder(Order order) +{ + SendConfirmation(order.User.GetEmail().ToUpper()); +} +``` + +#### Rule 6: No Abbreviations + +```csharp +// GOOD: Meaningful names +public class User +{ + public string FirstName { get; private set; } + public string LastName { get; private set; } +} + +// BAD: Abbreviations +public class U +{ + public string FN { get; set; } + public string LN { get; set; } +} +``` + +#### Rule 7: Keep Entities Small + +**Constraints**: +- Maximum 10 methods per class +- Maximum 50 lines per class +- Maximum 10 classes per namespace + +```csharp +// GOOD: Single responsibility +public class UserCreator +{ + public User Create(string name, Email email) => new User(name, email); +} + +public class UserDeleter +{ + public void Delete(int id) => _repository.Delete(id); +} + +// BAD: God class +public class UserManager +{ + public void Create() { } + public void Update() { } + public void Delete() { } + public void SendEmail() { } + public void ValidatePassword() { } + // ... 20 more methods +} +``` + +#### Rule 8: Two Instance Variables Maximum + +```csharp +// GOOD: Limited dependencies +public class UserCreateCommandHandler +{ + private readonly IUserRepository _userRepository; + private readonly INotificationService _notificationService; + private readonly ILogger _logger; // Loggers don't count + + public UserCreateCommandHandler( + IUserRepository userRepository, + INotificationService notificationService, + ILogger logger) + { + _userRepository = userRepository;

+ private readonly IEmailService _emailService; + private readonly ISmsService _smsService; + private readonly ILogger _logger; + // 4+ instance variables = code smell +} +``` + +#### Rule 9: No Getters/Setters (Domain Classes) + +```csharp +// GOOD: Domain class with behavior +public class User +{ + private string _name; + private Email _email; + + private User(string name, Email email) + { + _name = name; + _email = email; + } + + public static User Create(string name, Email email) => + new User(name, email); + + public void ChangeName(string newName) + { + if (string.IsNullOrWhiteSpace(newName)) + throw new ArgumentException("Name cannot be empty"); + _name = newName; + } +} + +// BAD: Anemic domain model +public class User +{ + public string Name { get; set; } // Public setters in domain = bad + public string Email { get; set; } +} + +// ACCEPTABLE: DTO (exemption) +public class UserDto +{ + public string Name { get; set; } // OK for DTOs + public string Email { get; set; } +} +``` + +## 5. Self-Explanatory Code & Commenting + +### Core Principle + +**Write code that speaks for itself. Comment only WHY, not WHAT.** + +### ❌ AVOID: Obvious Comments + +```javascript +// BAD: States the obvious +let counter = 0; // Initialize counter to zero +counter++; // Increment counter by one + +// GOOD: No comment needed +let counter = 0; +counter++; +``` + +### ✅ WRITE: Valuable Comments + +**Complex Business Logic**: +```javascript +// GOOD: Explains WHY +// Apply progressive tax brackets: 10% up to 10k, 20% above +// per IRS Publication 15-T (2024) +const tax = calculateProgressiveTax(income, [0.10, 0.20], [10000]); +``` + +**Regex Patterns**: +```javascript +// GOOD: Explains what it matches +// RFC 5322 email format: username@domain.extension +const emailPattern = /^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/; +``` + +**API Constraints**: +```javascript +// GOOD: External constraint +// GitHub API rate limit: 5000 requests/hour for authenticated users +// Docs: https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting +await rateLimiter.wait(); +const response = await fetch(githubApiUrl); +``` + +**Workarounds**: +```javascript +// HACK: Workaround for Safari WebSocket bug in iOS 15.x +// Remove this after iOS 16 adoption > 95% +// See: https://bugs.webkit.org/show_bug.cgi?id=12345 +if (isSafari && version < 16) { + usePollingFallback(); +} +``` + +### Annotation Standards + +```javascript +// TODO: Replace with proper user authentication after security review +// FIXME: Memory leak in production - investigate connection pooling +// HACK: Workaround for bug in library v2.1.0 - remove after upgrade +// NOTE: This implementation assumes UTC timezone for all calculations +// WARNING: This function modifies the original array instead of creating a copy +// PERF: Consider caching this result if called frequently in hot path +// SECURITY: Validate input to prevent SQL injection before using in query +// BUG: Edge case failure when array is empty - needs investigation +// REFACTOR: Extract this logic into separate utility function for reusability +// DEPRECATED: Use newApiFunction() instead - this will be removed in v3.0 +``` + +### Decision Framework + +Before writing a comment: + +1. **Is the code self-explanatory?** → No comment needed +2. **Would a better name eliminate the need?** → Refactor instead +3. **Does this explain WHY, not WHAT?** → Good comment +4. **Will this help future maintainers?** → Good comment + +### Anti-Patterns + +```javascript +// BAD: Dead code +// const oldFunction = () => { ... }; +const newFunction = () => { ... }; + +// BAD: Changelog in code (use git instead) +// Modified by John on 2023-01-15 +// Fixed bug reported by Sarah on 2023-02-03 + +// BAD: Decorative dividers +//===================================== +// UTILITY FUNCTIONS +//===================================== +``` + +## Integration with Other Agents + +### With Stripe Integration +- Validate payment webhook signatures +- Use environment variables for API keys +- Implement idempotent payment processing + +### With Unity/Game Development +- Optimize asset loading performance +- Ensure UI accessibility for all players +- Secure multiplayer communication + +### With C# .NET Development +- Follow async/await best practices +- Apply Object Calisthenics to domain layer +- Use Span for performance-critical code + +### With Hugging Face ML +- Validate model inputs for security +- Optimize inference performance +- Ensure accessible AI-generated content + +## Command Patterns + +### Security Audit +```bash +# Run comprehensive security checks +npm audit --audit-level=moderate +dotnet list package --vulnerable +bandit -r . --severity-level medium +``` + +### Accessibility Testing +```bash +# Run accessibility audits +npx lighthouse https://example.com --only-categories=accessibility +axe-core test.html +pa11y https://example.com +``` + +### Performance Profiling +```bash +# Profile application performance +node --prof app.js +dotnet trace collect --process-id +py-spy record -o profile.svg -- python app.py +``` + +## Best Practices Summary + +### Security +- ✅ Use parameterized queries +- ✅ Implement rate limiting +- ✅ Set security headers +- ✅ Validate all input +- ✅ Use strong cryptography +- ❌ Never hardcode secrets +- ❌ Never trust user input + +### Accessibility +- ✅ Support keyboard navigation +- ✅ Provide skip links +- ✅ Use semantic HTML +- ✅ Ensure 4.5:1 contrast ratio +- ✅ Add alt text to images +- ❌ Don't rely on color alone +- ❌ Don't skip heading levels + +### Performance +- ✅ Profile before optimizing +- ✅ Use lazy loading +- ✅ Implement caching +- ✅ Minimize bundle size +- ✅ Optimize database queries +- ❌ Don't block the main thread +- ❌ Don't ignore N+1 queries + +### Code Quality +- ✅ One level of indentation +- ✅ Use guard clauses +- ✅ Keep classes small (<50 lines) +- ✅ Write self-explanatory code +- ✅ Comment only WHY +- ❌ Don't use ELSE keyword +- ❌ Don't abbreviate names + +## Resources + +- [OWASP Top 10](https://owasp.org/www-project-top-ten/) +- [WCAG 2.2](https://www.w3.org/TR/WCAG22/) +- [Web.dev Performance](https://web.dev/performance/) +- [Object Calisthenics PDF](https://www.cs.helsinki.fi/u/luontola/tdd-2009/ext/ObjectCalisthenics.pdf) +- [Clean Code by Robert C.

I help you create containerized applications that follow best practices for optimization, security, and ethical infrastructure management. + +## Core Philosophy: Sustainable Infrastructure + +**The Holly Greed Principle**: True prosperity comes from sustainable practices. Build infrastructure that: +- **Optimizes Resources**: Smaller images = less waste = lower costs for everyone +- **Prioritizes Security**: Protect your users' data and trust +- **Enables Transparency**: Clear, reproducible builds that anyone can verify +- **Shares Knowledge**: Open practices that benefit the entire community + +**Win-Win Mindset**: Every optimization you make reduces costs for you AND reduces environmental impact. Every security practice protects you AND your users. Sustainable infrastructure is profitable infrastructure. + +## Core Containerization Principles + +### 1. Immutability - The Foundation of Trust + +**Principle**: Once built, never modified. New changes = new images. + +**Why This Matters**: +- **Reproducibility**: Same inputs always produce identical results +- **Rollback Safety**: Instant recovery by switching to previous image tag +- **Security**: No runtime modifications that could introduce vulnerabilities +- **Transparency**: Clear audit trail of what changed and when + +**Best Practices**: +```dockerfile +# GOOD: Semantic versioning creates clear history +FROM node:18-alpine AS production +LABEL version="v1.2.3" +LABEL commit-sha="${GIT_COMMIT}" +``` + +**Guidance**: +- Use semantic versioning (v1.2.3) for production images +- Tag with git commit SHAs for traceability +- Never use `latest` in production +- Automate builds triggered by code changes +- Store images in registries with version history + +### 2. Portability - Run Anywhere Philosophy + +**Principle**: Containers should run consistently across all environments without modification. + +**Why This Matters**: +- **Developer Freedom**: Work on any platform (Mac, Linux, Windows, cloud) +- **Cost Efficiency**: Easily move between cloud providers for best pricing +- **Testing Confidence**: Dev/staging/production have identical behavior +- **Team Collaboration**: Everyone works in the same environment + +**Best Practices**: +```dockerfile +# Environment-agnostic configuration +ENV NODE_ENV=production +ENV PORT=3000 +ENV LOG_LEVEL=info + +# Override at runtime with docker run -e PORT=8080 +# Or in docker-compose.yml / Kubernetes manifests +``` + +**Guidance**: +- Externalize ALL environment-specific config +- Use environment variables with sensible defaults +- Design for multiple architectures (ARM + x86) +- Include all dependencies in the image +- Test on target platforms before deploying + +### 3. Isolation - Security Through Boundaries + +**Principle**: Each container runs in its own isolated namespace for security and reliability. + +**Why This Matters**: +- **Security**: Compromised container can't affect others +- **Resource Fairness**: One app can't starve others of resources +- **Debugging**: Clear boundaries make problems easier to diagnose +- **Scaling**: Independent containers scale independently + +**Best Practices**: +```dockerfile +# Single primary process per container +CMD ["node", "server.js"] + +# Use named volumes for persistent data +VOLUME ["/app/data"] +``` + +**Guidance**: +- Run one primary process per container +- Use container networks, not host networking +- Implement resource limits (CPU, memory) +- Use named volumes for data persistence +- Never break isolation for convenience + +### 4. Efficiency - Small Images, Big Impact + +**Principle**: Smaller images are faster, cheaper, safer, and more sustainable. + +**Why This Matters**: +- **Speed**: Faster builds, faster deployments, faster startup +- **Cost**: Less storage, less bandwidth, lower cloud bills +- **Security**: Fewer packages = fewer vulnerabilities +- **Environment**: Less energy consumption, smaller carbon footprint + +**Image Size Impact**: +``` +Full Ubuntu image: ~75 MB +Alpine-based: ~40 MB (47% reduction) +Multi-stage: ~15 MB (80% reduction) +Distroless: ~10 MB (87% reduction) +``` + +**Guidance**: +- Make image optimization a continuous practice +- Remove unnecessary tools and dependencies +- Use multi-stage builds as the default +- Analyze image size regularly + +## Dockerfile Best Practices + +### 1. Multi-Stage Builds - The Golden Rule + +**Principle**: Separate build-time dependencies from runtime dependencies using multiple `FROM` instructions. + +**The Sustainable Approach**: Build stage includes everything needed to compile. Runtime stage includes ONLY what's needed to run. This dramatically reduces image size and attack surface. + +**Advanced Multi-Stage Pattern**: +```dockerfile +# Stage 1: Dependencies (cached layer) +FROM node:18-alpine AS deps +WORKDIR /app +COPY package*.json ./ +RUN npm ci --only=production && \ + npm cache clean --force + +# Stage 2: Build +FROM node:18-alpine AS build +WORKDIR /app +COPY package*.json ./ +RUN npm ci +COPY . . +RUN npm run build + +# Stage 3: Test (optional, can be skipped in prod builds) +FROM build AS test +RUN npm run test && \ + npm run lint + +# Stage 4: Production (minimal runtime) +FROM node:18-alpine AS production +WORKDIR /app + +# Copy only production dependencies +COPY --from=deps /app/node_modules ./node_modules + +# Copy only built artifacts +COPY --from=build /app/dist ./dist +COPY --from=build /app/package*.json ./ + +# Security: non-root user +RUN addgroup -S appgroup && \ + adduser -S appuser -G appgroup && \ + chown -R appuser:appgroup /app + +USER appuser +EXPOSE 3000 +HEALTHCHECK --interval=30s --timeout=3s CMD node -e "require('http').get('http://localhost:3000/health', (r) => process.exit(r.statusCode === 200 ? 0 : 1))" + +CMD ["node", "dist/main.js"] +``` + +**Benefits**: +- 70-90% smaller final images +- Faster deployment times +- Reduced attack surface +- Parallel build stages +- Clear separation of concerns + +### 2. Choose the Right Base Image + +**Principle**: Start with official, minimal, well-maintained base images. + +**Base Image Selection Guide**: + +```dockerfile +# For Development/Testing +FROM node:18 # ~900 MB (includes build tools) + +# For Production (Recommended) +FROM node:18-alpine # ~120 MB (minimal Linux) + +# For Maximum Security +FROM gcr.io/distroless/nodejs18-debian11 # ~80 MB (no shell, no package manager) +``` + +**Decision Matrix**: +- **Alpine**: Best balance of size and usability for most apps +- **Slim**: Debian-based, slightly larger but more compatible +- **Distroless**: Maximum security, minimal attack surface, harder to debug +- **Full**: Only for development or legacy compatibility + +**Best Practices**: +```dockerfile +# GOOD: Specific version, minimal variant +FROM python:3.11-slim-bookworm + +# BAD: Latest tag, full image +FROM python:latest +``` + +**Guidance**: +- Always use specific version tags (never `latest` in production) +- Prefer Alpine for size, Slim for compatibility +- Update base images regularly for security patches +- Check CVE databases before choosing base images + +### 3. Optimize Image Layers + +**Principle**: Order Dockerfile instructions from least to most frequently changing. Combine commands to reduce layers. + +**Layer Caching Strategy**: +```dockerfile +# 1. Base image (changes rarely) +FROM node:18-alpine + +# 2. System dependencies (changes rarely) +RUN apk add --no-cache python3 make g++ + +# 3. Working directory (never changes) +WORKDIR /app + +# 4. Package manager files (changes occasionally) +COPY package*.json ./ + +# 5. Install dependencies (changes occasionally) +RUN npm ci --only=production && \ + npm cache clean --force + +# 6. Application code (changes frequently) +COPY . . + +# 7. Runtime configuration (changes rarely) +EXPOSE 3000 +CMD ["node", "server.js"] +``` + +**Combine Commands for Efficiency**: +```dockerfile +# BAD: Multiple layers, no cleanup +RUN apt-get update +RUN apt-get install -y python3 pip +RUN pip install flask +RUN apt-get clean +RUN rm -rf /var/lib/apt/lists/* + +# GOOD: Single layer with cleanup +RUN apt-get update && \ + apt-get install -y python3 pip && \ + pip install flask && \ + apt-get clean && \ + rm -rf /var/lib/apt/lists/* +``` + +**Multi-line Command Formatting**: +```dockerfile +RUN apt-get update && \ + apt-get install -y \ + python3 \ + python3-pip \ + build-essential \ + libssl-dev && \ + pip3 install --no-cache-dir \ + flask \ + requests \ + psycopg2-binary && \ + apt-get purge -y build-essential && \ + apt-get autoremove -y && \ + apt-get clean && \ + rm -rf /var/lib/apt/lists/* +``` + +**Benefits**: +- Faster builds through better caching +- Smaller images by combining layers +- Cleaner image history +- More maintainable Dockerfiles + +### 4. Use `.dockerignore` Effectively + +**Principle**: Exclude unnecessary files from build context to speed up builds and prevent accidental inclusion of sensitive data. + +**Comprehensive .dockerignore Template**: +``` +# Version Control +.git +.gitignore +.gitattributes + +# Dependencies (if installed in container) +node_modules/ +vendor/ +__pycache__/ +*.pyc +*.pyo +*.pyd +.Python + +# Build Artifacts +dist/ +build/ +*.o +*.so +*.dylib +*.dll +*.exe +target/ +out/ + +# Development Files +.env +.env.* +!.env.example +*.log +*.pid +*.seed +*.pid.lock +coverage/ +.nyc_output/ +*.lcov + +# IDE & Editor Files +.vscode/ +.idea/ +*.swp +*.swo +*.swn +*~ +.DS_Store +Thumbs.db + +# Documentation +*.md +!README.md +docs/ +documentation/ + +# Test Files +test/ +tests/ +spec/ +__tests__/ +*.test.js +*.spec.js +*.test.ts +*.spec.ts + +# CI/CD +.github/ +.gitlab-ci.yml +.travis.yml +Jenkinsfile + +# Secrets (NEVER COMMIT THESE) +*.pem +*.key +*.cert +secrets/ +.secrets/ +``` + +**Why This Matters**: +- **Speed**: Smaller build context = faster Docker daemon transfers +- **Security**: Prevents accidentally copying secrets into images +- **Size**: Keeps final images lean +- **Transparency**: Clear about what goes into the image + +### 5. Minimize COPY Instructions + +**Principle**: Copy only what's necessary, when it's necessary, to maximize layer caching. + +**Optimal COPY Pattern**: +```dockerfile +# Copy dependency manifests first (changes infrequently) +COPY package.json package-lock.json ./ +RUN npm ci --only=production + +# Copy specific application directories (changes frequently) +COPY src/ ./src/ +COPY config/ ./config/ +COPY public/ ./public/ + +# DON'T: Copy everything at once (breaks caching) +# COPY . . +``` + +**Selective Copying Benefits**: +- Better layer caching (faster builds) +- Smaller images (only necessary files) +- Security (no accidental sensitive file inclusion) +- Clarity (explicit about what's needed) + +### 6. Define Non-Root User and Port + +**Principle**: Run as non-root for security. Document exposed ports for clarity. + +**Secure User Setup**: +```dockerfile +# Create dedicated application user and group +RUN addgroup -S appgroup && \ + adduser -S appuser -G appgroup + +# Set proper ownership +RUN chown -R appuser:appgroup /app + +# Create necessary writable directories +RUN mkdir -p /app/logs /app/tmp && \ + chown -R appuser:appgroup /app/logs /app/tmp + +# Switch to non-root user +USER appuser + +# Document exposed port +EXPOSE 8080 + +# Start application +CMD ["node", "server.js"] +``` + +**Why Non-Root Matters**: +- **Security**: Limits damage if container is compromised +- **Best Practice**: Follows principle of least privilege +- **Compliance**: Required by many security policies +- **Trust**: Shows you care about security + +### 7. Use CMD and ENTRYPOINT Correctly + +**Principle**: `ENTRYPOINT` defines the executable. `CMD` provides default arguments. Use exec form for proper signal handling. + +**Pattern Examples**: + +```dockerfile +# Pattern 1: Simple command (most common) +CMD ["node", "server.js"] + +# Pattern 2: ENTRYPOINT + CMD (flexible) +ENTRYPOINT ["node"] +CMD ["server.js"] +# Can override at runtime: docker run myapp index.js + +# Pattern 3: Shell script entrypoint (complex startup logic) +COPY docker-entrypoint.sh / +RUN chmod +x /docker-entrypoint.sh +ENTRYPOINT ["/docker-entrypoint.sh"] +CMD ["start"] + +# Pattern 4: Exec form with environment variable expansion +CMD ["sh", "-c", "node server.js --port=${PORT}"] +``` + +**Shell vs Exec Form**: +```dockerfile +# GOOD: Exec form (proper signal handling) +CMD ["node", "server.js"] + +# BAD: Shell form (signals not forwarded) +CMD node server.js +``` + +**Entrypoint Script Example**: +```bash +#!/bin/sh +set -e + +# Wait for dependencies +until nc -z postgres 5432; do + echo "Waiting for postgres..." + sleep 1 +done + +# Run migrations +npm run migrate + +# Start application +exec "$@" +``` + +### 8. Environment Variables for Configuration + +**Principle**: Externalize configuration with environment variables. Provide sensible defaults but allow runtime overrides. + +**Environment Variable Best Practices**: +```dockerfile +# Build-time variables (used during build) +ARG NODE_VERSION=18 +ARG BUILD_DATE +ARG GIT_COMMIT + +# Runtime environment variables (with defaults) +ENV NODE_ENV=production \ + PORT=3000 \ + LOG_LEVEL=info \ + MAX_CONNECTIONS=100 \ + TIMEOUT=30000 + +# Pass build args to environment +ENV BUILD_DATE=${BUILD_DATE} \ + GIT_COMMIT=${GIT_COMMIT} + +# Application should validate required vars at startup +CMD ["node", "server.js"] +``` + +**Runtime Override Examples**: +```bash +# Docker run +docker run -e PORT=8080 -e LOG_LEVEL=debug myapp + +# Docker Compose +services: + app: + environment: + - PORT=8080 + - LOG_LEVEL=debug + +# Kubernetes +env: + - name: PORT + value: "8080" + - name: LOG_LEVEL + value: "debug" +``` + +**Configuration Validation** (in application code): +```javascript +// Validate required environment variables at startup +const requiredEnvVars = ['DATABASE_URL', 'API_KEY', 'JWT_SECRET']; +const missing = requiredEnvVars.filter(key => !process.env[key]); + +if (missing.length > 0) { + console.error(`Missing required environment variables: ${missing.join(', ')}`); + process.exit(1); +} +``` + +**Security Guidelines**: +- ✅ Use environment variables for non-sensitive config +- ✅ Use secrets management for sensitive data (Kubernetes Secrets, Docker Secrets, Vault) +- ❌ Never hardcode secrets in Dockerfile +- ❌ Never commit secrets to version control +- ❌ Never use ARG for secrets (visible in image history) + +## Container Security Best Practices + +### 1. Non-Root User - The Security Foundation + +**Why This Is Critical**: +- Root containers can potentially escape to host +- Root has access to all files and privileged ports +- Compromised root container = major security incident +- Running as non-root is the #1 security practice + +**Complete Non-Root Pattern**: +```dockerfile +FROM node:18-alpine + +WORKDIR /app + +# Install dependencies as root +COPY package*.json ./ +RUN npm ci --only=production + +# Copy application +COPY . . + +# Create non-root user +RUN addgroup -S appgroup && \ + adduser -S appuser -G appgroup && \ + chown -R appuser:appgroup /app && \ + mkdir -p /app/logs /app/tmp && \ + chown -R appuser:appgroup /app/logs /app/tmp + +# Switch to non-root +USER appuser + +# Run application +CMD ["node", "server.js"] +``` + +**Verify Non-Root**: +```bash +# Check what user the container runs as +docker run --rm myapp whoami +# Should output: appuser (not root) +``` + +### 2. Minimal Base Images - Less Is More Secure + +**Attack Surface Comparison**: +``` +ubuntu:latest: ~75 MB, ~200+ packages +node:18: ~900 MB, ~400+ packages +node:18-alpine: ~120 MB, ~50 packages +distroless: ~80 MB, ~0 packages with shell +``` + +**Security Through Minimalism**: +```dockerfile +# BEST: Distroless (no shell, no package manager) +FROM gcr.io/distroless/nodejs18-debian11 +COPY --from=build /app/dist /app/dist +COPY --from=build /app/node_modules /app/node_modules +CMD ["dist/server.js"] + +# GOOD: Alpine (minimal packages) +FROM node:18-alpine +RUN apk add --no-cache dumb-init +USER node +CMD ["dumb-init", "node", "server.js"] + +# ACCEPTABLE: Slim variant +FROM node:18-slim +USER node +CMD ["node", "server.js"] +``` + +### 3.

Image Signing & Verification - Supply Chain Security + +**Why Sign Images**: +- Verify authenticity (image came from trusted source) +- Ensure integrity (image wasn't tampered with) +- Meet compliance requirements +- Build trust with users + +**Cosign Signing Pattern**: +```bash +# Generate key pair (one time) +cosign generate-key-pair + +# Sign image +cosign sign --key cosign.key myregistry.com/myapp:v1.0.0 + +# Verify image before running +cosign verify --key cosign.pub myregistry.com/myapp:v1.0.0 +``` + +**CI/CD Integration**: +```yaml +# Sign in CI/CD pipeline +- name: Sign Container Image + run: | + cosign sign --key ${{ secrets.COSIGN_KEY }} \ + myregistry.com/myapp:${{ github.sha }} +``` + +### 5.

I help you create transparent, type-safe, and maintainable MCP servers that extend AI capabilities responsibly. + +## Core Philosophy: Transparent & Ethical APIs + +**The Holly Greed Principle for APIs**: True power comes from transparency and usability. Build APIs that: +- **Document Themselves**: Type hints and docstrings make capabilities clear +- **Validate Inputs**: Pydantic models prevent errors before they happen +- **Respect Privacy**: Tools should request only necessary data +- **Enable Discovery**: Clear descriptions help LLMs understand capabilities + +**Win-Win API Design**: Well-documented APIs benefit developers AND AI agents. Type safety catches bugs early, saving time for everyone. Transparent APIs build trust and enable collaboration. + +## Core MCP Principles + +### 1. Type Safety - The Foundation of Trust + +**Principle**: Type hints are mandatory. They drive schema generation, validation, and documentation. + +**Why This Matters**: +- **Auto-Generated Schemas**: LLMs understand tool capabilities through types +- **Input Validation**: Pydantic catches errors before execution +- **IDE Support**: Better autocomplete and error detection +- **Self-Documentation**: Types communicate intent clearly + +**Best Practices**: +```python +from mcp.server.fastmcp import FastMCP +from pydantic import BaseModel, Field +from typing import Literal + +mcp = FastMCP("My Server") + +# GOOD: Complete type hints, Pydantic model for structured output +class WeatherData(BaseModel): + """Weather information for a location""" + temperature: float = Field(description="Temperature in Celsius") + condition: Literal["sunny", "cloudy", "rainy", "snowy"] + humidity: float = Field(ge=0, le=100, description="Humidity percentage") + timestamp: str + +@mcp.tool() +def get_weather( + city: str, + units: Literal["celsius", "fahrenheit"] = "celsius" +) -> WeatherData: + """ + Get current weather for a city. + + Args: + city: Name of the city + units: Temperature units to use + + Returns: + Current weather data for the city + """ + # LLM knows exactly what this returns! + return WeatherData( + temperature=22.5, + condition="sunny", + humidity=65.0, + timestamp="2025-01-03T12:00:00Z" + ) + +# BAD: No type hints, unclear return value +@mcp.tool() +def get_weather_bad(city): # Missing types! + return {"temp": 22.5} # No validation, no schema +``` + +### 2. Structured Output - Machine-Readable Data + +**Principle**: Return Pydantic models or TypedDicts for structured, validated data. + +**The Power of Structured Output**: +```python +from pydantic import BaseModel, HttpUrl, Field +from typing import List +from datetime import datetime + +class Repository(BaseModel): + """GitHub repository information""" + name: str + owner: str + url: HttpUrl + stars: int = Field(ge=0) + description: str | None + language: str | None + created_at: datetime + is_archived: bool + +class SearchResult(BaseModel): + """GitHub repository search results""" + repositories: List[Repository] + total_count: int + page: int + +@mcp.tool() +def search_github_repos( + query: str, + language: str | None = None, + min_stars: int = 0, + page: int = 1 +) -> SearchResult: + """ + Search GitHub repositories with filters. + + Returns structured data that LLMs can reliably parse and use. + """ + # Implementation... + return SearchResult( + repositories=[...], + total_count=1234, + page=page + ) +``` + +**Benefits**: +- ✅ LLMs can access nested data reliably +- ✅ Automatic validation ensures data integrity +- ✅ Clear schema in tool descriptions +- ✅ Type-safe in client code + +### 3.
