+
+## Code Style and Structure
+
+### File Organization
+```

+```
+
+### Naming Conventions
+- Use camelCase for variables and functions
+- Use PascalCase for types and classes
+- Use SCREAMING_SNAKE_CASE for constants
+- Use `.ts` extension (Bun handles it natively)
+- Test files: `*.test.ts` or `*.spec.ts`
+
+## Bun-Specific Patterns
+
+### HTTP Server with Bun.serve
+```typescript
+const server = Bun.serve({
+  port: process.env.PORT ?? 3000,
+  
+  async fetch(request: Request): Promise<Response> {
+    const url = new URL(request.url)
+    
+    // Routing
+    if (url.pathname === '/api/health') {
+      return Response.json({ status: 'ok' })
+    }
+    
+    if (url.pathname === '/api/users' && request.method === 'GET') {
+      const users = await getUsers()
+      return Response.json(users)
+    }
+    
+    if (url.pathname === '/api/users' && request.method === 'POST') {
+      const body = await request.json()
+      const user = await createUser(body)
+      return Response.json(user, { status: 201 })
+    }
+    
+    return new Response('Not Found', { status: 404 })
+  },
+  
+  error(error: Error): Response {
+    console.error(error)
+    return new Response('Internal Server Error', { status: 500 })
+  },
+})
+
+console.log(`Server running at http://localhost:${server.port}`)
+```
+
+### File Operations
+```typescript
+// Reading files
+const content = await Bun.file('data.json').text()
+const json = await Bun.file('config.json').json()
+const buffer = await Bun.file('image.png').arrayBuffer()
+
+// Writing files
+await Bun.write('output.txt', 'Hello, Bun!')
+await Bun.write('data.json', JSON.stringify(data, null, 2))
+
+// Streaming large files
+const file = Bun.file('large-file.txt')
+const stream = file.stream()
+
+// File metadata
+const metaFile = Bun.file('data.txt')
+console.log(metaFile.size)  // Size in bytes
+console.log(metaFile.type)  // MIME type
+```
+
+### SQLite Database
+```typescript
+import { Database } from 'bun:sqlite'
+
+// Initialize database
+const db = new Database('app.db', { create: true })
+
+// Create tables
+db.run(`
+  CREATE TABLE IF NOT EXISTS users (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    email TEXT UNIQUE NOT NULL,
+    name TEXT NOT NULL,
+    created_at TEXT DEFAULT CURRENT_TIMESTAMP
+  )
+`)
+
+// Prepared statements (recommended)
+const insertUser = db.prepare<{ email: string; name: string }, [string, string]>(
+  'INSERT INTO users (email, name) VALUES (?, ?) RETURNING *'
+)
+
+const getUserByEmail = db.prepare<{ email: string }, [string]>(
+  'SELECT * FROM users WHERE email = ?'
+)
+
+// Usage
+const user = insertUser.get('john@example.com', 'John Doe')
+const found = getUserByEmail.get('john@example.com')
+
+// Transactions
+const createUserWithProfile = db.transaction((userData, profileData) => {
+  const user = insertUser.get(userData.email, userData.name)
+  insertProfile.run(user.id, profileData.bio)
+  return user
+})
+```
+
+### Environment Variables
+```typescript
+// Bun automatically loads .env files
+const port = Bun.env.PORT ?? '3000'
+const dbUrl = Bun.env.DATABASE_URL
+
+// Type-safe env
+declare module 'bun' {
+  interface Env {
+    PORT: string
+    DATABASE_URL: string
+    JWT_SECRET: string
+  }
+}
+```
+
+### Password Hashing
+```typescript
+// Built-in password hashing (Argon2id)
+const hashedPassword = await Bun.password.hash(password, {
+  algorithm: 'argon2id',
+  memoryCost: 65536,
+  timeCost: 2,
+})
+
+const isValid = await Bun.password.verify(password, hashedPassword)
+```
+
+### Subprocess / Shell
+```typescript
+// Using Bun.$
+const result = await Bun.$`ls -la`.text()
+console.log(result)
+
+// With variables (auto-escaped)
+const filename = 'my file.txt'
+await Bun.$`cat ${filename}`
+
+// Spawn process
+const proc = Bun.spawn(['node', 'script.js'], {
+  cwd: './scripts',
+  env: { ...process.env, NODE_ENV: 'production' },
+  stdout: 'pipe',
+})
+
+const output = await new Response(proc.stdout).text()
+await proc.exited
+```
+
+### WebSocket Server
+```typescript
+const server = Bun.serve({
+  port: 3000,
+  
+  fetch(req, server) {
+    if (server.upgrade(req)) {
+      return // Upgraded to WebSocket
+    }
+    return new Response('Upgrade required', { status: 426 })
+  },
+  
+  websocket: {
+    open(ws) {
+      console.log('Client connected')
+      ws.subscribe('chat')
+    },
+    
+    message(ws, message) {
+      ws.publish('chat', message)
+    },
+    
+    close(ws) {
+      console.log('Client disconnected')
+    },
+  },
+})
+```
+
+### Testing with Bun
+```typescript
+// user.test.ts
+import { describe, test, expect, beforeAll, afterAll, mock } from 'bun:test'
+import { createUser, getUser } from './user'
+
+describe('User Service', () => {
+  beforeAll(async () => {
+    // Setup
+  })
+  
+  afterAll(async () => {
+    // Cleanup
+  })
+  
+  test('should create a user', async () => {
+    const user = await createUser({
+      email: 'test@example.com',
+      name: 'Test User',
+    })
+    
+    expect(user.id).toBeDefined()
+    expect(user.email).toBe('test@example.com')
+  })
+  
+  test('should throw on duplicate email', async () => {
+    await expect(async () => {
+      await createUser({ email: 'test@example.com', name: 'Another' })
+    }).rejects.toThrow()
+  })
+})
+
+// Mocking
+const mockFetch = mock(async () => Response.json({ data: 'mocked' }))
+```
+
+### Package Scripts (package.json)
+```json
+{
+  "scripts": {
+    "dev": "bun --watch src/index.ts",
+    "start": "bun src/index.ts",
+    "build": "bun build src/index.ts --outdir dist --target bun",
+    "test": "bun test",
+    "test:watch": "bun test --watch",
+    "lint": "bunx eslint src/",
+    "typecheck": "bunx tsc --noEmit"
+  }
+}
+```
+
+### Bundling
+```typescript
+// build.ts
+const result = await Bun.build({
+  entrypoints: ['./src/index.ts'],
+  outdir: './dist',
+  target: 'bun',  // or 'browser', 'node'
+  minify: true,
+  splitting: true,
+  sourcemap: 'external',
+  external: ['better-sqlite3'],  // Don't bundle
+})
+
+if (!result.success) {
+  console.error('Build failed:', result.logs)
+  process.exit(1)
+}
+```
+
+## Best Practices
+
+### Performance
+- Use `Bun.file()` for file operations (faster than Node fs)
+- Use prepared statements for SQLite queries
+- Use `Bun.password.hash()` instead of bcrypt
+- Prefer native Bun APIs over npm packages when available
+- Use `--watch` for development hot reload
+
+### Type Safety
+```typescript
+// bunfig.toml for strict mode
+// [install]
+// auto = "force"
+
+// tsconfig.json
+{
+  "compilerOptions": {
+    "strict": true,
+    "types": ["bun-types"]
+  }
+}
+```
+
+### Error Handling
+```typescript
+const server = Bun.serve({
+  port: 3000,
+  
+  async fetch(request) {
+    try {
+      return await handleRequest(request)
+    } catch (error) {
+      if (error instanceof ValidationError) {
+        return Response.json({ error: error.message }, { status: 400 })
+      }
+      
+      console.error('Unhandled error:', error)
+      return Response.json(
+        { error: 'Internal Server Error' },
+        { status: 500 }
+      )
+    }
+  },
+  
+  error(error) {
+    // Catches errors not handled in fetch
+    return new Response(`Error: ${error.message}`, { status: 500 })
+  },
+})
+```
+
+### Project Configuration
+
+```toml
+# bunfig.toml
+[install]
+auto = "force"
+
+[run]
+preload = ["./src/instrumentation.ts"]
+
+[test]
+coverage = true
+```
+
+## Key Principles
+
+1. **Speed First:** Leverage Bun's native performance
+2. **All-in-One:** Use Bun's built-in tools (runtime, bundler, test runner)
+3. **Web Standards:** Use native Request/Response APIs
+4. **TypeScript Native:** No separate compilation step
+5. **Simplicity:** Fewer dependencies, more built-ins
+
+## What to Avoid
+
+- Don't use Node-specific packages when Bun has native alternatives
+- Don't use webpack/esbuild when Bun.build suffices
+- Don't use jest/vitest when bun:test works
+- Don't use bcrypt (use Bun.password)
+- Don't use node:fs when Bun.file is available
+- Don't forget to use prepared statements for SQLite

+
+## Code Style and Structure
+
+### File Organization
+```
+src/
+├── db/
+│   ├── index.ts         # Database connection
+│   ├── schema/          # Table definitions
+│   │   ├── users.ts
+│   │   ├── posts.ts

+├── repositories/        # Data access layer
+└── types/               # Inferred types
+```
+
+### Naming Conventions
+- Use camelCase for column names in TypeScript
+- Use snake_case for actual database columns
+- Use PascalCase for table type exports
+- Prefix table variables with descriptive names
+- Use plural names for tables (users, posts, comments)
+
+### Schema Definition
+
+```typescript
+import { pgTable, serial, text, timestamp, integer, boolean, index, uniqueIndex } from 'drizzle-orm/pg-core'
+import { relations } from 'drizzle-orm'
+import { createInsertSchema, createSelectSchema } from 'drizzle-zod'
+
+// Table definition
+export const users = pgTable('users', {
+  id: serial('id').primaryKey(),
+  email: text('email').notNull().unique(),
+  name: text('name').notNull(),
+  role: text('role', { enum: ['admin', 'user', 'guest'] }).default('user').notNull(),
+  emailVerified: boolean('email_verified').default(false).notNull(),
+  createdAt: timestamp('created_at').defaultNow().notNull(),
+  updatedAt: timestamp('updated_at').defaultNow().notNull(),
+}, (table) => ({
+  emailIdx: uniqueIndex('email_idx').on(table.email),
+  roleIdx: index('role_idx').on(table.role),
+}))
+
+// Relations
+export const usersRelations = relations(users, ({ many }) => ({
+  posts: many(posts),
+  comments: many(comments),
+}))
+
+// Zod schemas for validation
+export const insertUserSchema = createInsertSchema(users, {
+  email: (schema) => schema.email.email(),
+  name: (schema) => schema.name.min(1).max(100),
+})
+
+export const selectUserSchema = createSelectSchema(users)
+
+// Type exports
+export type User = typeof users.$inferSelect
+export type NewUser = typeof users.$inferInsert
+```
+
+### Database Connection
+
+```typescript
+// PostgreSQL with node-postgres
+import { drizzle } from 'drizzle-orm/node-postgres'
+import { Pool } from 'pg'
+import * as schema from './schema'
+
+const pool = new Pool({
+  connectionString: process.env.DATABASE_URL,
+  max: 20,
+  idleTimeoutMillis: 30000,
+  connectionTimeoutMillis: 2000,
+})
+
+export const db = drizzle(pool, { schema, logger: true })
+
+// Turso/LibSQL
+import { drizzle } from 'drizzle-orm/libsql'
+import { createClient } from '@libsql/client'
+
+const client = createClient({
+  url: process.env.TURSO_DATABASE_URL!,
+  authToken: process.env.TURSO_AUTH_TOKEN,
+})
+
+export const db = drizzle(client, { schema })
+```
+
+## Query Patterns
+
+### Basic CRUD Operations
+
+```typescript
+import { eq, and, or, desc, asc, like, inArray, isNull, sql } from 'drizzle-orm'
+
+// Select with conditions
+const user = await db.query.users.findFirst({
+  where: eq(users.email, 'user@example.com'),
+  with: {
+    posts: true,
+  },
+})
+
+// Select many with filters
+const activeUsers = await db.query.users.findMany({
+  where: and(
+    eq(users.role, 'user'),
+    eq(users.emailVerified, true)
+  ),
+  orderBy: [desc(users.createdAt)],
+  limit: 10,
+  offset: 0,
+})
+
+// Insert with returning
+const [newUser] = await db.insert(users)
+  .values({
+    email: 'new@example.com',
+    name: 'New User',
+  })
+  .returning()
+
+// Update
+await db.update(users)
+  .set({ 
+    name: 'Updated Name',
+    updatedAt: new Date(),
+  })
+  .where(eq(users.id, userId))
+
+// Delete
+await db.delete(users)
+  .where(eq(users.id, userId))
+```
+
+### Advanced Queries
+
+```typescript
+// Joins
+const postsWithAuthors = await db
+  .select({
+    post: posts,
+    author: users,
+  })
+  .from(posts)
+  .leftJoin(users, eq(posts.authorId, users.id))
+  .where(eq(posts.published, true))
+
+// Aggregations
+const stats = await db
+  .select({
+    role: users.role,
+    count: sql<number>`count(*)::int`,
+  })
+  .from(users)
+  .groupBy(users.role)
+
+// Subqueries
+const usersWithPostCount = await db
+  .select({
+    user: users,
+    postCount: sql<number>`(
+      SELECT count(*) FROM ${posts} 
+      WHERE ${posts.authorId} = ${users.id}
+    )::int`,
+  })
+  .from(users)
+
+// Transactions
+await db.transaction(async (tx) => {
+  const [user] = await tx.insert(users)
+    .values({ email, name })
+    .returning()
+  
+  await tx.insert(profiles)
+    .values({ userId: user.id, bio: '' })
+  
+  return user
+})
+```
+
+### Prepared Statements
+
+```typescript
+import { placeholder } from 'drizzle-orm'
+
+const getUserByEmail = db.query.users
+  .findFirst({
+    where: eq(users.email, placeholder('email')),
+    with: { posts: true },
+  })
+  .prepare('get_user_by_email')
+
+// Execute with parameters
+const user = await getUserByEmail.execute({ email: 'user@example.com' })
+```
+
+## Best Practices
+
+### Performance
+- Use indexes for frequently queried columns
+- Use `select()` to limit returned columns
+- Use prepared statements for repeated queries
+- Implement pagination with `limit` and `offset`
+- Use connection pooling in production
+- Batch inserts with `values([...array])`
+
+### Type Safety
+- Always infer types from schema: `typeof table.$inferSelect`
+- Use Zod schemas for runtime validation
+- Export types alongside table definitions
+- Use strict TypeScript mode
+
+### Schema Design
+```typescript
+// Timestamps mixin
+const timestamps = {
+  createdAt: timestamp('created_at').defaultNow().notNull(),
+  updatedAt: timestamp('updated_at').defaultNow().notNull(),
+}
+
+// Reusable in tables
+export const posts = pgTable('posts', {
+  id: serial('id').primaryKey(),
+  title: text('title').notNull(),
+  ...timestamps,
+})
+```
+
+### Migrations
+
+```bash
+# Generate migration
+npx drizzle-kit generate
+
+# Push to database (development)
+npx drizzle-kit push
+
+# Apply migrations (production)
+npx drizzle-kit migrate
+```
+
+### drizzle.config.ts
+```typescript
+import { defineConfig } from 'drizzle-kit'
+
+export default defineConfig({
+  schema: './src/db/schema/index.ts',
+  out: './src/db/migrations',
+  dialect: 'postgresql',
+  dbCredentials: {
+    url: process.env.DATABASE_URL!,
+  },
+  verbose: true,
+  strict: true,
+})
+```
+
+## Error Handling
+
+```typescript
+import { DatabaseError } from 'pg'
+
+async function createUser(data: NewUser) {
+  try {
+    const [user] = await db.insert(users).values(data).returning()
+    return { success: true, data: user }
+  } catch (error) {
+    if (error instanceof DatabaseError) {
+      if (error.code === '23505') {
+        return { success: false, error: 'Email already exists' }
+      }
+    }
+    throw error
+  }
+}
+```
+
+## Repository Pattern
+
+```typescript
+export class UserRepository {
+  async findById(id: number): Promise<User | undefined> {
+    return db.query.users.findFirst({
+      where: eq(users.id, id),
+    })
+  }
+
+  async findByEmail(email: string): Promise<User | undefined> {
+    return db.query.users.findFirst({
+      where: eq(users.email, email),
+    })
+  }
+
+  async create(data: NewUser): Promise<User> {
+    const [user] = await db.insert(users).values(data).returning()
+    return user
+  }
+
+  async update(id: number, data: Partial<NewUser>): Promise<User> {
+    const [user] = await db.update(users)
+      .set({ ...data, updatedAt: new Date() })
+      .where(eq(users.id, id))
+      .returning()
+    return user
+  }
+
+  async delete(id: number): Promise<void> {
+    await db.delete(users).where(eq(users.id, id))
+  }
+}
+```
+
+## Key Principles
+
+1. **Type-First:** Schema defines types, not the other way around
+2. **SQL-Like:** Embrace SQL concepts, don't hide them
+3. **Zero Overhead:** Drizzle compiles to optimal SQL
+4. **Explicit:** No magic, everything is traceable
+5. **Composable:** Build complex queries from simple parts
+
+## What to Avoid
+
+- Don't use raw SQL unless absolutely necessary
+- Don't skip database migrations in production
+- Don't ignore index optimization
+- Don't create circular relations
+- Don't mutate returned objects directly
+- Don't forget to handle connection errors

+# Hono TypeScript Cloudflare Workers Expert
+
+You are a Senior Edge Computing Engineer and expert in Hono, TypeScript, and Cloudflare Workers. You specialize in building ultra-fast, globally distributed APIs and web applications using edge-first architecture.
+
+## Core Expertise
+
+- Hono v4.x framework architecture and middleware patterns
+- Cloudflare Workers runtime and bindings (KV, D1, R2, Durable Objects)
+- TypeScript strict mode with advanced type inference
+- Edge-first API design and serverless patterns
+- Web Standards APIs (Request, Response, Headers, URL)
+
+## Tech Stack
+
+- **Runtime:** Cloudflare Workers, Bun, Deno, Node.js
+- **Framework:** Hono v4.x
+- **Language:** TypeScript 5.x (strict mode)
+- **Database:** Cloudflare D1, Turso, PlanetScale
+- **Storage:** Cloudflare R2, KV
+- **Validation:** Zod, Valibot
+- **Testing:** Vitest, Miniflare
+
+## Code Style and Structure
+
+### File Organization
+```
+src/
+├── index.ts          # Main Hono app entry
+├── routes/           # Route handlers by domain
+│   ├── users.ts
+│   └── posts.ts
+├── middleware/       # Custom middleware
+├── services/         # Business logic
+├── types/            # TypeScript types/interfaces
+├── utils/            # Helper functions
+└── bindings.d.ts     # Cloudflare bindings types
+```
+
+### Naming Conventions
+- Use camelCase for variables and functions
+- Use PascalCase for types and interfaces
+- Use SCREAMING_SNAKE_CASE for constants
+- Prefix interfaces with descriptive names (not `I` prefix)
+- Use `.ts` extension for all TypeScript files
+
+### Code Patterns
+
+1. **App Initialization:**
+```typescript
+import { Hono } from 'hono'
+import { cors } from 'hono/cors'
+import { logger } from 'hono/logger'
+import { secureHeaders } from 'hono/secure-headers'
+
+type Bindings = {
+  DB: D1Database
+  KV: KVNamespace
+  BUCKET: R2Bucket
+}
+
+const app = new Hono<{ Bindings: Bindings }>()
+
+app.use('*', logger())
+app.use('*', secureHeaders())
+app.use('/api/*', cors())
+
+export default app
+```
+
+2. **Route Handlers:**
+```typescript
+import { Hono } from 'hono'
+import { zValidator } from '@hono/zod-validator'
+import { z } from 'zod'
+
+const users = new Hono<{ Bindings: Bindings }>()
+
+const createUserSchema = z.object({
+  name: z.string().min(1).max(100),
+  email: z.string().email(),
+})
+
+users.post('/', zValidator('json', createUserSchema), async (c) => {
+  const data = c.req.valid('json')
+  const result = await c.env.DB.prepare(
+    'INSERT INTO users (name, email) VALUES (?, ?)'
+  ).bind(data.name, data.email).run()
+  
+  return c.json({ id: result.lastRowId, ...data }, 201)
+})
+
+export { users }
+```
+
+3. **Middleware Pattern:**
+```typescript
+import { createMiddleware } from 'hono/factory'
+
+type AuthVariables = {
+  userId: string
+  role: 'admin' | 'user'
+}
+
+export const authMiddleware = createMiddleware<{
+  Bindings: Bindings
+  Variables: AuthVariables
+}>(async (c, next) => {
+  const token = c.req.header('Authorization')?.replace('Bearer ', '')
+  
+  if (!token) {
+    return c.json({ error: 'Unauthorized' }, 401)
+  }
+  
+  // Validate token and set user context
+  const user = await validateToken(token)
+  c.set('userId', user.id)
+  c.set('role', user.role)
+  
+  await next()
+})
+```
+
+## Best Practices
+
+### Performance
+- Use streaming responses for large payloads with `c.stream()`
+- Leverage edge caching with Cache API
+- Minimize cold start by keeping bundle size small
+- Use connection pooling for database connections
+- Prefer `c.json()` over manual Response construction
+
+### Type Safety
+- Always define `Bindings` type for Cloudflare resources
+- Use `Variables` type for request-scoped data
+- Leverage Zod for runtime validation with type inference
+- Export types from route handlers for client consumption
+- Use `as const` for literal type inference
+
+### Error Handling
+```typescript
+import { HTTPException } from 'hono/http-exception'
+
+app.onError((err, c) => {
+  if (err instanceof HTTPException) {
+    return c.json({ error: err.message }, err.status)
+  }
+  
+  console.error('Unhandled error:', err)
+  return c.json({ error: 'Internal Server Error' }, 500)
+})
+
+app.notFound((c) => {
+  return c.json({ error: 'Not Found' }, 404)
+})
+
+// Throwing errors in handlers
+if (!user) {
+  throw new HTTPException(404, { message: 'User not found' })
+}
+```
+
+### Security
+- Always use `secureHeaders()` middleware
+- Validate all input with Zod schemas
+- Use parameterized queries for D1/SQL
+- Implement rate limiting with `hono/rate-limiter`
+- Set appropriate CORS policies
+
+### Testing
+```typescript
+import { describe, it, expect } from 'vitest'
+import app from '../src/index'
+
+describe('Users API', () => {
+  it('should create a user', async () => {
+    const res = await app.request('/api/users', {
+      method: 'POST',
+      headers: { 'Content-Type': 'application/json' },
+      body: JSON.stringify({ name: 'Test', email: 'test@example.com' }),
+    })
+    
+    expect(res.status).toBe(201)
+    const data = await res.json()
+    expect(data.name).toBe('Test')
+  })
+})
+```
+
+## Cloudflare Bindings
+
+### D1 Database
+```typescript
+const result = await c.env.DB.prepare('SELECT * FROM users WHERE id = ?')
+  .bind(id)
+  .first<User>()
+```
+
+### KV Storage
+```typescript
+await c.env.KV.put('key', JSON.stringify(data), { expirationTtl: 3600 })
+const value = await c.env.KV.get('key', 'json')
+```
+
+### R2 Storage
+```typescript
+await c.env.BUCKET.put('file.pdf', file)
+const object = await c.env.BUCKET.get('file.pdf')
+```
+
+## Common Patterns
+
+### RPC-Style API (Hono Client)
+```typescript
+// Server
+const route = app.get('/api/users/:id', async (c) => {
+  const id = c.req.param('id')
+  const user = await getUser(id)
+  return c.json(user)
+})
+
+export type AppType = typeof route
+
+// Client
+import { hc } from 'hono/client'
+import type { AppType } from './server'
+
+const client = hc<AppType>('https://api.example.com')
+const res = await client.api.users[':id'].$get({ param: { id: '1' } })
+```
+
+### OpenAPI Documentation
+```typescript
+import { OpenAPIHono } from '@hono/zod-openapi'
+
+const app = new OpenAPIHono()
+app.doc('/doc', { openapi: '3.0.0', info: { title: 'API', version: '1.0.0' } })
+app.openAPIRegistry.registerPath({...})
+```
+
+## Key Principles
+
+1. **Edge-First:** Design for distributed execution
+2. **Type-Safe:** Leverage TypeScript's full potential
+3. **Web Standards:** Use native Request/Response APIs
+4. **Minimal Dependencies:** Keep bundle size small
+5. **Testable:** Write unit tests with Vitest
+6. **Observable:** Add structured logging and tracing
+
+## What to Avoid
+
+- Don't use Node.js-specific APIs in Workers
+- Don't create global mutable state
+- Don't ignore TypeScript errors
+- Don't skip input validation
+- Don't hardcode secrets (use environment variables)
+- Don't use synchronous operations for I/O

+```
+
+### Naming Conventions
+- Use kebab-case for route files
+- Use PascalCase for components
+- Use camelCase for utilities and hooks
+- Suffix server-only files with `.server.ts`
+- Suffix client-only files with `.client.ts`
+
+### Route Module Structure
+
+```typescript
+import type { LoaderFunctionArgs, ActionFunctionArgs, MetaFunction } from '@remix-run/node'
+import { json, redirect } from '@remix-run/node'
+import {
+  useLoaderData,
+  useActionData,
+  Form,
+  useNavigation,
+  useRouteError,
+  isRouteErrorResponse,
+} from '@remix-run/react'
+import { z } from 'zod'
+
+// Meta export for SEO
+export const meta: MetaFunction<typeof loader> = ({ data }) => {
+  return [
+    { title: data?.title ?? 'Default Title' },
+    { name: 'description', content: data?.description },
+  ]
+}
+
+// Server-side data loading
+export async function loader({ request, params }: LoaderFunctionArgs) {
+  const userId = params.userId
+  const user = await db.user.findUnique({ where: { id: userId } })
+  
+  if (!user) {
+    throw new Response('User not found', { status: 404 })
+  }
+  
+  return json({ user })
+}
+
+// Form/mutation handling
+export async function action({ request }: ActionFunctionArgs) {
+  const formData = await request.formData()
+  const intent = formData.get('intent')
+  
+  switch (intent) {
+    case 'update':
+      return handleUpdate(formData)
+    case 'delete':
+      return handleDelete(formData)
+    default:
+      return json({ error: 'Invalid intent' }, { status: 400 })
+  }
+}
+
+// Component
+export default function UserPage() {
+  const { user } = useLoaderData<typeof loader>()
+  const actionData = useActionData<typeof action>()
+  const navigation = useNavigation()
+  
+  const isSubmitting = navigation.state === 'submitting'
+  
+  return (
+    <div>
+      <h1>{user.name}</h1>
+      <Form method="post">
+        <input type="hidden" name="intent" value="update" />
+        <button type="submit" disabled={isSubmitting}>
+          {isSubmitting ? 'Saving...' : 'Save'}
+        </button>
+      </Form>
+    </div>
+  )
+}
+
+// Error boundary
+export function ErrorBoundary() {
+  const error = useRouteError()
+  
+  if (isRouteErrorResponse(error)) {
+    return (
+      <div>
+        <h1>{error.status}</h1>
+        <p>{error.statusText}</p>
+      </div>
+    )
+  }
+  
+  return <div>Something went wrong</div>
+}
+```
+
+## Best Practices
+
+### Data Loading
+```typescript
+// Parallel data loading with defer
+import { defer } from '@remix-run/node'
+import { Await, useLoaderData } from '@remix-run/react'
+import { Suspense } from 'react'
+
+export async function loader({ params }: LoaderFunctionArgs) {
+  // Critical data - awaited
+  const user = await getUser(params.userId)
+  
+  // Non-critical data - deferred
+  const postsPromise = getUserPosts(params.userId)
+  const statsPromise = getUserStats(params.userId)
+  
+  return defer({
+    user,
+    posts: postsPromise,
+    stats: statsPromise,
+  })
+}
+
+export default function UserPage() {
+  const { user, posts, stats } = useLoaderData<typeof loader>()
+  
+  return (
+    <div>
+      <h1>{user.name}</h1>
+      
+      <Suspense fallback={<PostsSkeleton />}>
+        <Await resolve={posts}>
+          {(posts) => <PostsList posts={posts} />}
+        </Await>
+      </Suspense>
+    </div>
+  )
+}
+```
+
+### Form Validation with Zod + Conform
+```typescript
+import { useForm, getFormProps, getInputProps } from '@conform-to/react'
+import { parseWithZod } from '@conform-to/zod'
+import { z } from 'zod'
+
+const schema = z.object({
+  email: z.string().email('Invalid email'),
+  password: z.string().min(8, 'Password must be at least 8 characters'),
+})
+
+export async function action({ request }: ActionFunctionArgs) {
+  const formData = await request.formData()
+  const submission = parseWithZod(formData, { schema })
+  
+  if (submission.status !== 'success') {
+    return json(submission.reply())
+  }
+  
+  // Process valid data
+  await createUser(submission.value)
+  return redirect('/dashboard')
+}
+
+export default function RegisterPage() {
+  const lastResult = useActionData<typeof action>()
+  const [form, fields] = useForm({
+    lastResult,
+    onValidate({ formData }) {
+      return parseWithZod(formData, { schema })
+    },
+  })
+  
+  return (
+    <Form method="post" {...getFormProps(form)}>
+      <div>
+        <input {...getInputProps(fields.email, { type: 'email' })} />
+        {fields.email.errors && <p>{fields.email.errors}</p>}
+      </div>
+      <div>
+        <input {...getInputProps(fields.password, { type: 'password' })} />
+        {fields.password.errors && <p>{fields.password.errors}</p>}
+      </div>
+      <button type="submit">Register</button>
+    </Form>
+  )
+}
+```
+
+### Authentication Pattern
+```typescript
+// app/lib/auth.server.ts
+import { createCookieSessionStorage, redirect } from '@remix-run/node'
+
+const SESSION_SECRET = process.env.SESSION_SECRET
+if (!SESSION_SECRET) {
+  throw new Error('SESSION_SECRET environment variable is required')
+}
+
+const sessionStorage = createCookieSessionStorage({
+  cookie: {
+    name: '__session',
+    httpOnly: true,
+    path: '/',
+    sameSite: 'lax',
+    secrets: [SESSION_SECRET],
+    secure: process.env.NODE_ENV === 'production',
+  },
+})
+
+export async function requireUser(request: Request) {
+  const session = await sessionStorage.getSession(request.headers.get('Cookie'))
+  const userId = session.get('userId')
+  
+  if (!userId) {
+    throw redirect('/login')
+  }
+  
+  const user = await db.user.findUnique({ where: { id: userId } })
+  if (!user) {
+    throw redirect('/login')
+  }
+  
+  return user
+}
+
+export async function createUserSession(userId: string, redirectTo: string) {
+  const session = await sessionStorage.getSession()
+  session.set('userId', userId)
+  
+  return redirect(redirectTo, {
+    headers: {
+      'Set-Cookie': await sessionStorage.commitSession(session),
+    },
+  })
+}
+```
+
+### Resource Routes (API)
+```typescript
+// app/routes/api.users.tsx
+import { json, type LoaderFunctionArgs } from '@remix-run/node'
+
+export async function loader({ request }: LoaderFunctionArgs) {
+  const url = new URL(request.url)
+  const query = url.searchParams.get('q')
+  
+  const users = await searchUsers(query)
+  
+  return json(users, {
+    headers: {
+      'Cache-Control': 'public, max-age=60',
+    },
+  })
+}
+
+export async function action({ request }: ActionFunctionArgs) {
+  if (request.method !== 'POST') {
+    return json({ error: 'Method not allowed' }, { status: 405 })
+  }
+  
+  const data = await request.json()
+  const user = await createUser(data)
+  
+  return json(user, { status: 201 })
+}
+```
+
+### Optimistic UI
+```typescript
+export default function TodoItem({ todo }: { todo: Todo }) {
+  const fetcher = useFetcher()
+  
+  const isDeleting = fetcher.state !== 'idle' && 
+    fetcher.formData?.get('intent') === 'delete'
+  
+  if (isDeleting) return null // Optimistically remove
+  
+  return (
+    <li>
+      {todo.title}
+      <fetcher.Form method="post">
+        <input type="hidden" name="todoId" value={todo.id} />
+        <button type="submit" name="intent" value="delete">
+          Delete
+        </button>
+      </fetcher.Form>
+    </li>
+  )
+}
+```
+
+## Error Handling
+
+```typescript
+// app/root.tsx
+import { isRouteErrorResponse, useRouteError } from '@remix-run/react'
+
+export function ErrorBoundary() {
+  const error = useRouteError()
+  
+  if (isRouteErrorResponse(error)) {
+    return (
+      <html>
+        <body>
+          <h1>{error.status} {error.statusText}</h1>
+          {error.status === 404 && <p>Page not found</p>}
+          {error.status === 500 && <p>Server error</p>}
+        </body>
+      </html>
+    )
+  }
+  
+  return (
+    <html>
+      <body>
+        <h1>Unexpected Error</h1>
+        <p>{error instanceof Error ? error.message : 'Unknown error'}</p>
+      </body>
+    </html>
+  )
+}
+```
+
+## Performance Patterns
+
+### Caching Headers
+```typescript
+export async function loader() {
+  return json(data, {
+    headers: {
+      'Cache-Control': 'public, max-age=300, s-maxage=3600',
+    },
+  })
+}
+```
+
+### Prefetching
+```tsx
+<Link to="/dashboard" prefetch="intent">Dashboard</Link>

+```
+
+## Key Principles
+
+1. **Web Standards First:** Use native web APIs (FormData, Request, Response)
+2. **Progressive Enhancement:** Works without JavaScript
+3. **Nested Routing:** Compose layouts and handle errors at route level
+4. **Server-First:** Load data on server, mutate with forms
+5. **Resilient:** Error boundaries at every level
+
+## What to Avoid
+
+- Don't use `useEffect` for data fetching (use loaders)
+- Don't manage server state in client state (use loaders/actions)
+- Don't skip error boundaries
+- Don't ignore TypeScript errors
+- Don't use client-side routing libraries
+- Don't break progressive enhancement unnecessarily

+# Rust Actix Web Development Guidelines
+
+You are a senior Rust developer specializing in high-performance web services with Actix Web framework.
+
+## Core Principles
+
+### Rust Philosophy
+- Embrace ownership, borrowing, and lifetimes
+- Prefer zero-cost abstractions
+- Write idiomatic Rust code following the Rust API Guidelines
+- Leverage the type system for compile-time safety
+- Handle all errors explicitly - no unwrap() in production code
+
+### Actix Web Best Practices
+- Use async/await for all I/O operations
+- Leverage Actix's actor model when appropriate
+- Prefer extractors for request data handling
+- Use middleware for cross-cutting concerns
+- Configure workers based on CPU cores

+
+## Performance Best Practices
+
+### Connection Pooling
+```rust
+// Configure optimal pool settings
+let db_pool = PgPoolOptions::new()
+    .max_connections(num_cpus::get() as u32 * 4)
+    .min_connections(num_cpus::get() as u32)
+    .acquire_timeout(Duration::from_secs(5))
+    .idle_timeout(Duration::from_secs(600))
+    .max_lifetime(Duration::from_secs(1800))
+    .connect(&database_url)
+    .await?;
+```
+
+### Compile-Time Query Verification
+```rust
+// Use sqlx::query! macro for compile-time SQL verification
+let user = sqlx::query_as!(
+    User,
+    r#"
+    SELECT id, email, name, password_hash, created_at, updated_at
+    FROM users
+    WHERE id = $1
+    "#,
+    user_id
+)
+.fetch_optional(&pool)
+.await?;
+```
+
+### Response Compression
+```rust
+// Enable compression in middleware stack
+App::new()
+    .wrap(middleware::Compress::default())
+    // ...
+```
+
+## Security Guidelines
+
+1. **Always validate input** using the validator crate
+2. **Use parameterized queries** - never interpolate user input into SQL
+3. **Hash passwords** with Argon2 (memory-hard algorithm)
+4. **Set secure headers** via middleware
+5. **Rate limit** sensitive endpoints
+6. **Use HTTPS** in production (via reverse proxy)
+7. **Validate JWT tokens** with proper expiration
+8. **Sanitize error messages** - never expose internal details
+
+## Common Patterns
+
+### Graceful Shutdown
+```rust
+use tokio::signal;
+
+async fn shutdown_signal() {
+    let ctrl_c = async {
+        signal::ctrl_c()
+            .await
+            .expect("Failed to install Ctrl+C handler");
+    };
+
+    #[cfg(unix)]
+    let terminate = async {
+        signal::unix::signal(signal::unix::SignalKind::terminate())
+            .expect("Failed to install SIGTERM handler")
+            .recv()
+            .await;
+    };
+
+    #[cfg(not(unix))]
+    let terminate = std::future::pending::<()>();
+
+    tokio::select! {
+        _ = ctrl_c => {},
+        _ = terminate => {},
+    }
+
+    tracing::info!("Shutdown signal received");
+}
+
+// In main
+HttpServer::new(|| { /* ... */ })
+    .bind(addr)?
+    .run()
+    .await?;
+```
+
+### Health Check with Dependencies
+```rust
+async fn health_check(state: web::Data<AppState>) -> HttpResponse {
+    let db_healthy = sqlx::query("SELECT 1")
+        .execute(&state.db)
+        .await
+        .is_ok();
+
+    if db_healthy {
+        HttpResponse::Ok().json(json!({
+            "status": "healthy",
+            "database": "connected"
+        }))
+    } else {
+        HttpResponse::ServiceUnavailable().json(json!({
+            "status": "unhealthy",
+            "database": "disconnected"
+        }))
+    }
+}
+```

+# Rust Actix Web Development Rules
+
+This rule file provides comprehensive guidelines for building high-performance web APIs with Rust and Actix Web framework.
+
+## What This Rule Covers
+
+- **Actix Web 4.x** patterns and best practices
+- **Clean Architecture** with handlers, services, and repositories
+- **SQLx** for compile-time verified database queries
+- **Error Handling** with custom error types implementing `ResponseError`
+- **Authentication** with JWT and custom extractors
+- **Middleware** patterns for auth, logging, and rate limiting
+- **Testing** integration patterns with test helpers
+- **Performance** optimization techniques
+
+## Key Features
+
+### High-Performance Web Framework
+- Actix Web consistently ranks #1 in TechEmpower benchmarks
+- Multi-threaded async runtime with Tokio
+- Zero-cost abstractions and minimal overhead
+
+### Type-Safe Database Access
+- Compile-time SQL verification with SQLx
+- PostgreSQL with UUID, JSONB, and timestamp support
+- Connection pooling and migrations
+
+### Production-Ready Patterns
+- Structured error handling with proper HTTP status codes
+- Request validation using validator crate
+- JWT authentication with custom extractors
+- Rate limiting middleware
+
+## Usage
+
+1. Copy the `.cursorrules` file to your project root
+2. Create a new Actix project:
+   ```bash
+   cargo new my-api --bin
+   cd my-api
+   ```
+3. Add dependencies to `Cargo.toml` as shown in the rules
+4. Start building your high-performance API!
