Use decision trees below to find the right product, then load detailed references.\n\n## Prerequisites\n\n- When sandboxing blocks the deployment network calls, rerun with `sandbox_permissions=require_escalated`.\n- The deployment might take a few minutes. Use appropriate timeout values.\n\n## Authentication (Required Before Deploy)\n\nVerify auth before `wrangler deploy`, `wrangler pages deploy`, or `npm run deploy`:\n\n```bash\nnpx wrangler whoami    # Shows account if authenticated\n```\n\nNot authenticated? → `references/wrangler/auth.md`\n- Interactive/local: `wrangler login` (one-time OAuth)\n- CI/CD: Set `CLOUDFLARE_API_TOKEN` env var\n\n## Quick Decision Trees\n\n### \"I need to run code\"\n\n```\nNeed to run code?\n├─ Serverless functions at the edge → workers/\n├─ Full-stack web app with Git deploys → pages/\n├─ Stateful coordination/real-time → durable-objects/\n├─ Long-running multi-step jobs → workflows/\n├─ Run containers → containers/\n├─ Multi-tenant (customers deploy code) → workers-for-platforms/\n├─ Scheduled tasks (cron) → cron-triggers/\n├─ Lightweight edge logic (modify HTTP) → snippets/\n├─ Process Worker execution events (logs/observability) → tail-workers/\n└─ Optimize latency to backend infrastructure → smart-placement/\n```\n\n### \"I need to store data\"\n\n```\nNeed storage?\n├─ Key-value (config, sessions, cache) → kv/\n├─ Relational SQL → d1/ (SQLite) or hyperdrive/ (existing Postgres/MySQL)\n├─ Object/file storage (S3-compatible) → r2/\n├─ Message queue (async processing) → queues/\n├─ Vector embeddings (AI/semantic search) → vectorize/\n├─ Strongly-consistent per-entity state → durable-objects/ (DO storage)\n├─ Secrets management → secrets-store/\n├─ Streaming ETL to R2 → pipelines/\n└─ Persistent cache (long-term retention) → cache-reserve/\n```\n\n### \"I need AI/ML\"\n\n```\nNeed AI?\n├─ Run inference (LLMs, embeddings, images) → workers-ai/\n├─ Vector database for RAG/search → vectorize/\n├─ Build stateful AI agents → agents-sdk/\n├─ Gateway for any AI provider (caching, routing) → ai-gateway/\n└─ AI-powered search widget → ai-search/\n```\n\n### \"I need networking/connectivity\"\n\n```\nNeed networking?\n├─ Expose local service to internet → tunnel/\n├─ TCP/UDP proxy (non-HTTP) → spectrum/\n├─ WebRTC TURN server → turn/\n├─ Private network connectivity → network-interconnect/\n├─ Optimize routing → argo-smart-routing/\n├─ Optimize latency to backend (not user) → smart-placement/\n└─ Real-time video/audio → realtimekit/ or realtime-sfu/\n```\n\n### \"I need security\"\n\n```\nNeed security?\n├─ Web Application Firewall → waf/\n├─ DDoS protection → ddos/\n├─ Bot detection/management → bot-management/\n├─ API protection → api-shield/\n├─ CAPTCHA alternative → turnstile/\n└─ Credential leak detection → waf/ (managed ruleset)\n```\n\n### \"I need media/content\"\n\n```\nNeed media?\n├─ Image optimization/transformation → images/\n├─ Video streaming/encoding → stream/\n├─ Browser automation/screenshots → browser-rendering/\n└─ Third-party script management → zaraz/\n```\n\n### \"I need infrastructure-as-code\"\n\n```\nNeed IaC?

The deploy requires escalated network access when sandbox networking blocks outbound requests.\n\nExample guidance to the user:\n\n```\nThe deploy needs escalated network access to deploy to Cloudflare. I can rerun the command with escalated permissions—want me to proceed?\n```\n\n## Other files in this skill\n\n-

building AI-powered agents on Durable Objects with state, WebSockets, SQL, scheduling, and AI integration.\n\n## Core Value\nBuild stateful, globally distributed AI agents with persistent memory, real-time connections, scheduled tasks, and async workflows.\n\n## When to Use\n- Persistent state + memory required\n- Real-time WebSocket connections\n- Long-running workflows (minutes/hours)\n- Chat interfaces with AI models\n- Scheduled/recurring tasks with state\n- DB queries with agent state\n\n## What Type of Agent?\n\n| Use Case | Class | Key Features |\n|----------|-------|--------------|\n| AI chat interface | `AIChatAgent` | Auto-streaming, tools, message history, resumable |\n| MCP tool provider | `Agent` + MCP | Expose tools to AI systems |\n| Custom logic/routing | `Agent` | Full control, WebSockets, email, SQL |\n| Real-time collaboration | `Agent` | WebSocket state, broadcasts |\n| Email processing | `Agent` | `onEmail()` handler |\n\n## Quick Start\n\n**AI Chat Agent:**\n```typescript\nimport { AIChatAgent } from \"agents\";\nimport { openai } from \"@ai-sdk/openai\";\n\nexport class ChatAgent extends AIChatAgent<Env> {\n  async onChatMessage(onFinish) {\n    return this.streamText({\n      model: openai(\"gpt-4\"),\n      messages: this.messages,\n      onFinish,\n    });\n  }\n}\n```\n\n**Base Agent:**\n```typescript\nimport { Agent } from \"agents\";\n\nexport class MyAgent extends Agent<Env> {\n  onStart() {\n    this.sql`CREATE TABLE IF NOT EXISTS users (id TEXT PRIMARY KEY)`;\n  }\n  \n  async onRequest(request: Request) {\n    return Response.json({ state: this.state });\n  }\n}\n```\n\n## Reading Order\n\n| Task | Files to Read |\n|------|---------------|\n| Quick start | README only |\n| Build chat agent | README → api.md (AIChatAgent) → patterns.md |\n| Setup project | README → configuration.md |\n| Add React frontend | README → api.md (Client Hooks) → patterns.md |\n| Build MCP server | api.md (MCP) → patterns.md |\n| Background tasks | api.md (Scheduling, Task Queue) → patterns.md |\n| Debug issues | gotchas.md |\n\n## Package Entry Points\n\n| Import | Purpose |\n|--------|---------|\n| `agents` | Server-side Agent classes, lifecycle |\n| `agents/react` | `useAgent()` hook for WebSocket connections |\n| `agents/ai-react` | `useAgentChat()` hook for AI chat

AIChatAgent\n\nFor AI chat with auto-streaming, message history, tools, resumable streaming.\n\n```ts\nimport { AIChatAgent } from \"agents\";\nimport { openai } from \"@ai-sdk/openai\";\n\nexport class ChatAgent extends AIChatAgent<Env> {\n  async onChatMessage(onFinish) {\n    return this.streamText({\n      model: openai(\"gpt-4\"),\n      messages: this.messages, // Auto-managed message history\n      tools: {\n        getWeather: {\n          description: \"Get weather\",\n          parameters: z.object({ city: z.string() }),\n          execute: async ({ city }) => `Sunny, 72°F in ${city}`\n        }\n      },\n      onFinish, // Persist response to this.messages\n    });\n  }\n}\n```\n\n### Agent (Base Class)\n\nFull control for custom logic, WebSockets, email, and SQL.\n\n```ts\nimport { Agent } from \"agents\";\n\nexport class MyAgent extends Agent<Env, State> {\n  // Lifecycle methods below\n}\n```\n\n**Type params:** `Agent<Env, State, ConnState>` - Env bindings, agent state, connection state\n\n## Lifecycle Hooks\n\n```ts\nonStart() { // Init/restart\n  this.sql`CREATE TABLE IF NOT EXISTS users (id TEXT, name TEXT)`;\n}\n\nasync onRequest(req: Request) { // HTTP\n  const {pathname} = new URL(req.url);\n  if (pathname === \"/users\") return Response.json(this.sql<{id,name}>`SELECT * FROM users`);\n  return new Response(\"Not found\", {status: 404});\n}\n\nasync onConnect(conn: Connection<ConnState>, ctx: ConnectionContext) { // WebSocket\n  conn.accept();\n  conn.setState({userId: ctx.request.headers.get(\"X-User-ID\")});\n  conn.send(JSON.stringify({type: \"connected\", state: this.state}));\n}\n\nasync onMessage(conn: Connection<ConnState>, msg: WSMessage) { // WS messages\n  const m = JSON.parse(msg as string);\n  this.setState({messages: [...this.state.messages, m]});\n  this.connections.forEach(c => c.send(JSON.stringify(m)));\n}\n\nasync onEmail(email: AgentEmail) { // Email routing\n  this.sql`INSERT INTO emails (from_addr,subject,body) VALUES (${email.from},${email.headers.get(\"subject\")},${await email.text()})`;\n}\n```\n\n## State, SQL, Scheduling\n\n```ts\n// State\nthis.setState({count: 42}); // Auto-syncs\nthis.setState({...this.state, count: this.state.count + 1});\n\n// SQL (parameterized queries prevent injection)\nthis.sql`CREATE TABLE IF NOT EXISTS users (id TEXT PRIMARY KEY, name TEXT)`;\nthis.sql`INSERT INTO users (id,name) VALUES (${userId},${name})`;\nconst users = this.sql<{id,name}>`SELECT * FROM users WHERE id = ${userId}`;\n\n// Scheduling\nawait this.schedule(new

this.cancelSchedule(scheduleId);\n```\n\n## RPC Methods (@callable)\n\n```ts\nimport { Agent, callable } from \"agents\";\n\nexport class MyAgent extends Agent<Env> {\n  @callable()\n  async processTask(input: {text: string}): Promise<{result: string}> {\n    return { result: await this.env.AI.run(\"@cf/meta/llama-3.1-8b-instruct\", {prompt: input.text}) };\n  }\n}\n// Client: const result = await agent.processTask({ text: \"Hello\" });\n// Must return JSON-serializable values\n```\n\n## Connections & AI\n\n```ts\n// Connections (type: Agent<Env, State, ConnState>)\nthis.connections.forEach(c => c.send(JSON.stringify(msg))); // Broadcast\nconn.setState({userId:\"123\"}); conn.close(1000, \"Goodbye\");\n\n// Workers AI\nconst r = await this.env.AI.run(\"@cf/meta/llama-3.1-8b-instruct\", {prompt});\n\n// Manual streaming (prefer AIChatAgent)\nconst stream = await client.chat.completions.create({model: \"gpt-4\", messages, stream: true});\nfor await (const chunk of stream) conn.send(JSON.stringify({chunk: chunk.choices[0].delta.content}));\n```\n\n**Type-safe state:** `Agent<Env, State, ConnState>` - third param types `conn.state`\n\n## MCP Integration\n\nModel Context Protocol for exposing tools:\n\n```ts\n// Register & use MCP server\nawait this.mcp.registerServer(\"github\", {\n  url: env.MCP_SERVER_URL,\n  auth: { type: \"oauth\", clientId: env.GITHUB_CLIENT_ID, clientSecret: env.GITHUB_CLIENT_SECRET }\n});\nconst tools = await this.mcp.getAITools([\"github\"]);\nreturn this.streamText({ model: openai(\"gpt-4\"), messages: this.messages, tools, onFinish });\n```\n\n## Task Queue\n\n```ts\nawait this.queue(\"processVideo\", { videoId: \"abc123\" }); // Add task\nconst tasks = await this.dequeue(10); // Process up to 10\n```\n\n## Context & Cleanup\n\n```ts\nconst agent = getCurrentAgent<MyAgent>(); // Get current instance\nasync destroy() { /* cleanup before agent destroyed */ }\n```\n\n## AI Integration\n\n```ts\n// Workers AI\nconst r = await this.env.AI.run(\"@cf/meta/llama-3.1-8b-instruct\", {prompt});\n\n// Manual streaming (prefer AIChatAgent for auto-streaming)\nconst stream = await client.chat.completions.create({model: \"gpt-4\", messages, stream: true});\nfor await (const chunk of stream) {\n  if (chunk.choices[0]?.delta?.content) conn.send(JSON.stringify({chunk: chunk.choices[0].delta.content}));\n}\n```\n\n## Client Hooks (React)\n\n```ts\n// useAgent() - WebSocket connection + RPC\nimport { useAgent } from \"agents/react\";\nconst agent = useAgent({ agent: \"MyAgent\", name: \"user-123\" }); // name for idFromName\nconst result = await agent.processTask({ text: \"Hello\" }); // Call @callable methods\n// agent.readyState: 0=CONNECTING, 1=OPEN, 2=CLOSING, 3=CLOSED\n\n// useAgentChat() - AI chat UI\nimport { useAgentChat } from \"agents/ai-react\";\nconst agent = useAgent({ agent: \"ChatAgent\" });\nconst { messages, input, handleInputChange, handleSubmit, isLoading, stop, clearHistory } = \n  useAgentChat({ \n    agent, \n    maxSteps: 5,        // Max tool iterations\n    resume: true,       // Auto-resume on disconnect\n    onToolCall: async (toolCall) => {\n      // Client tools (human-in-the-loop)\n      if (toolCall.toolName === \"confirm\") return { ok: window.confirm(\"Proceed?\") };\n    }\n  });\n// status: \"ready\" | \"submitted\" | \"streaming\" | \"error\"\n```\n\n## references/agents-sdk/configuration.md (verbatim)\n\n# Configuration\n\n## Wrangler Setup\n\n```jsonc\n{\n  \"name\": \"my-agents-app\",\n  \"durable_objects\": {\n    \"bindings\": [\n      {\"name\": \"MyAgent\", \"class_name\": \"MyAgent\"}\n    ]\n  },\n  \"migrations\": [\n    {\"tag\": \"v1\", \"new_sqlite_classes\": [\"MyAgent\"]}\n  ],\n  \"ai\": {\n    \"binding\": \"AI\"\n  }\n}\n```\n\n## Environment Bindings\n\n**Type-safe pattern:**\n\n```typescript\ninterface Env {\n  AI?: Ai;                              // Workers AI\n  MyAgent?: DurableObjectNamespace<MyAgent>;\n  ChatAgent?: DurableObjectNamespace<ChatAgent>;\n  DB?: D1Database;                      // D1 database\n  KV?: KVNamespace;                     // KV storage\n  R2?: R2Bucket;                        // R2 bucket\n  OPENAI_API_KEY?: string;              // Secrets\n  GITHUB_CLIENT_ID?: string;            // MCP OAuth credentials\n  GITHUB_CLIENT_SECRET?: string;\n  QUEUE?: Queue;                        // Queues\n}\n```\n\n**Best practice:** Define all DO bindings in Env interface for type safety.\n\n## Deployment\n\n```bash\n# Local dev\nnpx wrangler dev\n\n# Deploy production\nnpx wrangler deploy\n\n# Set secrets\nnpx wrangler secret put OPENAI_API_KEY\n```\n\n## Agent Routing\n\n**Recommended: Use route helpers**\n\n```typescript\nimport { routeAgent } from \"agents\";\n\nexport default {\n  fetch(request: Request, env: Env) {\n    return routeAgent(request, env);\n  }\n}\n```\n\nHelper routes requests to agents automatically based on URL patterns.\n\n**Manual routing (advanced):**\n\n```typescript\nexport default {\n  async fetch(request: Request, env: Env) {\n    const url = new URL(request.url);\n    \n    // Named ID (deterministic)\n    const id = env.MyAgent.idFromName(\"user-123\");\n    \n    // Random ID (from URL param)\n    // const id = env.MyAgent.idFromString(url.searchParams.get(\"id\"));\n    \n    const stub = env.MyAgent.get(id);\n    return stub.fetch(request);\n  }\n}\n```\n\n**Multi-agent setup:**\n\n```typescript\nimport { routeAgent } from \"agents\";\n\nexport default {\n  fetch(request: Request, env: Env) {\n    const url = new URL(request.url);\n    \n    // Route by path\n    if (url.pathname.startsWith(\"/chat\")) {\n      return routeAgent(request, env, \"ChatAgent\");\n    }\n    if (url.pathname.startsWith(\"/task\")) {\n      return routeAgent(request, env, \"TaskAgent\");\n    }\n    \n    return new Response(\"Not found\", { status: 404 });\n  }\n}\n```\n\n## Email Routing\n\n**Code setup:**\n\n```typescript\nimport { routeAgentEmail } from \"agents\";\n\nexport default {\n  fetch: (req: Request, env: Env) => routeAgent(req, env),\n  email: (message: ForwardableEmailMessage, env: Env) => {\n    return routeAgentEmail(message, env);\n  }\n}\n```\n\n**Dashboard setup:**\n\nConfigure email routing in Cloudflare dashboard:\n\n```\nDestination: Workers with Durable Objects\nWorker: my-agents-app\n```\n\nThen handle in agent:\n\n```typescript\nexport class EmailAgent extends Agent<Env> {\n  async onEmail(email: AgentEmail) {\n    const text = await email.text();\n    // Process email\n  }\n}\n```\n\n## AI Gateway (Optional)\n\n```typescript\n// Enable caching/routing through AI Gateway\nconst response = await this.env.AI.run(\n  \"@cf/meta/llama-3.1-8b-instruct\",\n  { prompt },\n  {\n    gateway: {\n      id: \"my-gateway-id\",\n      skipCache: false,\n      cacheTtl: 3600\n    }\n  }\n);\n```\n\n## MCP Configuration (Optional)\n\nFor exposing tools via Model Context Protocol:\n\n```typescript\n// wrangler.jsonc - Add MCP OAuth secrets\n{\n  \"vars\": {\n    \"MCP_SERVER_URL\": \"https://mcp.example.com\"\n  }\n}\n\n// Set secrets via CLI\n// npx wrangler secret put GITHUB_CLIENT_ID\n// npx wrangler secret put GITHUB_CLIENT_SECRET\n```\n\nThen register in agent code (see api.md MCP section).\n\n## references/agents-sdk/gotchas.md (verbatim)\n\n# Gotchas & Best Practices\n\n## Common Errors\n\n### \"setState() not syncing\"\n\n**Cause:** Mutating state directly or not calling `setState()` after modifications  \n**Solution:** Always use `setState()` with immutable updates:\n```ts\n// ❌ this.state.count++\n// ✅ this.setState({...this.state, count: this.state.count + 1})\n```\n\n### \"Message history grows unbounded (AIChatAgent)\"\n\n**Cause:** `this.messages` in `AIChatAgent` accumulates all messages indefinitely  \n**Solution:** Manually trim old messages periodically:\n```ts\nexport class ChatAgent extends AIChatAgent<Env> {\n  async onChatMessage(onFinish) {\n    // Keep only last 50 messages\n    if (this.messages.length > 50) {\n      this.messages = this.messages.slice(-50);\n    }\n    \n    return this.streamText({ model: openai(\"gpt-4\"), messages: this.messages, onFinish });\n  }\n}\n```\n\n### \"SQL injection vulnerability\"\n\n**Cause:** Direct string interpolation in SQL queries\n**Solution:** Use parameterized queries:\n```ts\n// ❌ this.sql`...WHERE id = '${userId}'`\n// ✅ this.sql`...WHERE id = ${userId}`\n```\n\n### \"WebSocket connection timeout\"\n\n**Cause:** Not calling `conn.accept()` in `onConnect`\n**Solution:** Always accept connections:\n```ts\nasync onConnect(conn: Connection, ctx: ConnectionContext) { conn.accept(); conn.setState({userId: \"123\"}); }\n```\n\n### \"Schedule limit exceeded\"\n\n**Cause:** More than 1000 scheduled tasks per agent\n**Solution:** Clean up old schedules and limit creation rate:\n```ts\nasync checkSchedules() { if ((await this.getSchedules()).length > 800) console.warn(\"Near limit!\"); }\n```\n\n### \"AI Gateway unavailable\"\n\n**Cause:** AI service timeout or quota exceeded  \n**Solution:** Add error handling and fallbacks:\n```ts\ntry { \n  return await this.env.AI.run(model, {prompt}); \n} catch (e) { \n  console.error(\"AI error:\", e);\n  return {error: \"Unavailable\"}; \n}\n```\n\n### \"@callable method returns undefined\"\n\n**Cause:** Method doesn't return JSON-serializable value, or has non-serializable types  \n**Solution:** Ensure return values are plain objects/arrays/primitives:\n```ts\n// ❌ Returns class instance\n@callable()\nasync getData() { return new Date(); }\n\n// ✅ Returns serializable object\n@callable()\nasync getData() { return { timestamp: Date.now() }; }\n```\n\n### \"Resumable stream not resuming\"\n\n**Cause:** Stream ID must be deterministic for resumption to work  \n**Solution:** Use AIChatAgent (automatic) or ensure consistent stream IDs:\n```ts\n// AIChatAgent handles this automatically\nexport class ChatAgent extends AIChatAgent<Env> {\n  // Resumption works out of the box\n}\n```\n\n### \"MCP connection loss on hibernation\"\n\n**Cause:** MCP server connections don't survive hibernation  \n**Solution:** Re-register servers in `onStart()` or check connection status:\n```ts\nonStart() {\n  // Re-register MCP servers after hibernation\n  await this.mcp.registerServer(\"github\", { url: env.MCP_URL, auth: {...} });\n}\n```\n\n### \"Agent not found\"\n\n**Cause:** Durable Object binding missing or incorrect class name  \n**Solution:** Verify DO binding in wrangler.jsonc and class name matches\n\n## Rate Limits & Quotas\n\n| Resource/Limit | Value | Notes |\n|----------------|-------|-------|\n| CPU per request | 30s (std), 300s (max) | Set in wrangler.jsonc |\n| Memory per instance | 128MB | Shared with WebSockets |\n| Storage per agent | 10GB | SQLite storage |\n| Scheduled tasks | 1000 per agent | Monitor with `getSchedules()` |\n| WebSocket connections | Unlimited | Within memory limits |\n| SQL columns | 100 | Per table |\n| SQL row size | 2MB | Key + value |\n| WebSocket message | 32MiB | Max size |\n| DO requests/sec | ~1000 | Per unique DO instance; rate limit if needed |\n| AI Gateway (Workers AI) | Model-specific | Check dashboard for limits |\n| MCP requests | Depends on server | Implement retry/backoff |\n\n## Best Practices\n\n### State Management\n- Use immutable updates: `setState({...this.state, key: newValue})`\n- Trim unbounded arrays (messages, logs) periodically\n- Store large data in SQL, not state\n\n### SQL Usage\n- Create tables in `onStart()`, not `onRequest()`\n- Use parameterized queries: `` sql`WHERE id = ${id}` `` (NOT `` sql`WHERE id = '${id}'` ``)\n- Index frequently queried columns\n\n### Scheduling\n- Monitor schedule count: `await this.getSchedules()`\n- Cancel completed tasks to stay under 1000 limit\n- Use cron strings for recurring tasks\n\n### WebSockets\n- Always call `conn.accept()` in `onConnect()`\n- Handle client disconnects gracefully\n- Broadcast to `this.connections` efficiently\n\n### AI Integration\n- Use `AIChatAgent` for chat interfaces (auto-streaming, resumption)\n- Trim message history to avoid token limits\n- Handle AI errors with try/catch and fallbacks\n\n### Production Deployment\n- **Rate limiting:** Implement request throttling for high-traffic agents (>1000 req/s)\n- **Monitoring:** Log critical errors, track schedule count, monitor storage usage\n- **Graceful degradation:** Handle AI service outages with fallbacks\n- **Message trimming:** Enforce max history length (e.g., 100 messages) in AIChatAgent\n- **MCP reliability:** Re-register servers on hibernation, implement retry logic\n\n## references/agents-sdk/patterns.md (verbatim)\n\n# Patterns & Use Cases\n\n## AI Chat w/Tools\n\n**Server (AIChatAgent):**\n\n```ts\nimport { AIChatAgent } from \"agents\";\nimport { openai } from \"@ai-sdk/openai\";\nimport { tool } from \"ai\";\nimport { z } from \"zod\";\n\nexport class ChatAgent extends AIChatAgent<Env> {\n  async onChatMessage(onFinish) {\n    return this.streamText({\n

(toolCall.toolName === \"confirmAction\") {\n      return { confirmed: window.confirm(`Confirm: ${toolCall.args.action}?`) };\n    }\n  }\n});\n```\n\n## Task Queue & Scheduled Processing\n\n```ts\nexport class TaskAgent extends Agent<Env> {\n  onStart() { \n    this.schedule(\"*/5 * * * *\", \"processQueue\", {}); // Every 5 min\n    this.schedule(\"0 0 * * *\",

Chat\n\nCustom protocols (non-AI):\n\n```ts\nexport class ChatAgent extends Agent<Env> {\n  async onConnect(conn: Connection, ctx: ConnectionContext) {\n    conn.accept();\n    conn.setState({userId: ctx.request.headers.get(\"X-User-ID\") || \"anon\"});\n    conn.send(JSON.stringify({type: \"history\", messages: this.state.messages}));\n  }\n  \n  async onMessage(conn: Connection, msg: WSMessage)

=> c.send(JSON.stringify({type: \"new_email\", from, summary})));\n    if (summary.includes(\"urgent\")) await this.schedule(0, \"sendAutoReply\", { to: from });\n  }\n}\n```\n\n## Real-time Collaboration\n\n```ts\nexport class GameAgent extends Agent<Env> {\n  initialState = { players: [], gameStarted: false };\n  \n  async onConnect(conn: Connection, ctx: ConnectionContext) {\n

the site's secret filter.\n\n# Cloudflare AI Gateway\n\nExpert guidance for implementing Cloudflare AI Gateway - a universal gateway for AI model providers with analytics, caching, rate limiting, and routing capabilities.\n\n## When to Use This Reference\n\n- Setting up AI Gateway for any AI provider (OpenAI, Anthropic, Workers AI, etc.)\n- Implementing caching, rate limiting, or request retry/fallback\n- Configuring dynamic routing with A/B testing or model fallbacks\n- Managing provider API keys securely with BYOK\n- Adding security features (guardrails, DLP)\n- Setting up observability with logging and custom metadata\n- Debugging AI Gateway requests or optimizing configurations\n\n## Quick Start\n\n**What's your setup?**\n\n- **Using Vercel AI SDK** → Pattern 1 (recommended) - see [sdk-integration.md](./sdk-integration.md)\n- **Using OpenAI SDK** → Pattern 2 - see [sdk-integration.md](./sdk-integration.md)\n- **Cloudflare Worker + Workers AI** → Pattern 3 - see [sdk-integration.md](./sdk-integration.md)\n- **Direct HTTP (any language)** → Pattern 4 - see [configuration.md](./configuration.md)\n- **Framework (LangChain, etc.)** → See [sdk-integration.md](./sdk-integration.md)\n\n## Pattern 1: Vercel AI SDK (Recommended)\n\nMost modern pattern using official `ai-gateway-provider` package with automatic fallbacks.\n\n```typescript\nimport { createAiGateway } from 'ai-gateway-provider';\nimport { createOpenAI } from '@ai-sdk/openai';\nimport { generateText } from 'ai';\n\nconst gateway = createAiGateway({\n  accountId: process.env.CF_ACCOUNT_ID,\n  gateway: process.env.CF_GATEWAY_ID,\n});\n\nconst openai = createOpenAI({ \n  apiKey: YOUR_KEY \n});\n\n// Single model\nconst { text } = await generateText({\n  model: gateway(openai('gpt-4o')),\n  prompt: 'Hello'\n});\n\n// Automatic fallback array\nconst { text } = await generateText({\n  model: gateway([\n    openai('gpt-4o'),              // Try first\n    anthropic('claude-sonnet-4-5'), // Fallback\n  ]),\n  prompt: 'Hello'\n});\n```\n\n**Install:** `npm install ai-gateway-provider ai @ai-sdk/openai @ai-sdk/anthropic`\n\n## Pattern 2: OpenAI SDK\n\nDrop-in replacement for OpenAI API with multi-provider support.\n\n```typescript\nimport OpenAI from 'openai';\n\nconst client = new OpenAI({\n  apiKey: YOUR_KEY\n  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/compat`,\n  defaultHeaders: {\n    'cf-aig-authorization': `Bearer ${cfToken}` // For authenticated gateways\n  }\n});\n\n// Switch providers by changing model format: {provider}/{model}\nconst response = await client.chat.completions.create({\n  model: 'openai/gpt-4o', // or 'anthropic/claude-sonnet-4-5'\n  messages: [{ role: 'user', content: 'Hello!' }]\n});\n```\n\n## Pattern 3: Workers AI Binding\n\nFor Cloudflare Workers using Workers AI.\n\n```typescript\nexport default {\n  async fetch(request, env, ctx) {\n    const response = await env.AI.run(\n      '@cf/meta/llama-3-8b-instruct',\n      { messages: [{ role: 'user', content: 'Hello!' }] },\n      { \n        gateway: { \n          id: 'my-gateway',\n          metadata: { userId: '123', team: 'engineering' }\n        } \n      }\n    );\n    \n    return Response.json(response);\n  }\n};\n```\n\n## Headers Quick Reference\n\n| Header | Purpose | Example | Notes |\n|--------|---------|---------|-------|\n| `cf-aig-authorization` | Gateway auth | `Bearer {token}` | Required for authenticated gateways |\n| `cf-aig-metadata` | Tracking | `{\"userId\":\"x\"}` | Max 5 entries, flat structure |\n| `cf-aig-cache-ttl` | Cache duration | `3600` | Seconds, min 60, max 2592000 (30 days) |\n| `cf-aig-skip-cache` | Bypass cache | `true` | - |\n| `cf-aig-cache-key` | Custom cache key | `my-key` | Must be unique per response |\n| `cf-aig-collect-log` | Skip logging | `false` | Default: true |\n| `cf-aig-cache-status` | Cache hit/miss | Response only | `HIT` or `MISS` |\n\n## In This Reference\n\n| File | Purpose |\n|------|---------|\n| [sdk-integration.md](./sdk-integration.md) | Vercel AI SDK, OpenAI SDK, Workers binding patterns

Rate Limiting, Logging\n```\n\n**Key URL patterns:**\n- Unified API (OpenAI-compatible): `https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/compat/chat/completions`\n- Provider-specific: `https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/{provider}/{endpoint}`\n- Dynamic routes: Use route name instead of model: `dynamic/{route-name}`\n\n## Gateway Types\n\n1. **Unauthenticated Gateway**: Open access (not recommended for production)\n2. **Authenticated Gateway**: Requires `cf-aig-authorization` header with Cloudflare API token (recommended)\n\n## Provider Authentication Options\n\n1. **Unified Billing**: Use AI Gateway billing to pay for inference (keyless mode - no provider API key needed)\n2. **BYOK (Store Keys)**: Store provider API keys in Cloudflare dashboard\n3. **Request Headers**: Include provider API key in each request\n\n## Related Skills\n\n- [Workers AI](../workers-ai/README.md) - For `env.AI.run()` details\n- [Agents

`https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,\n  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }\n});\n```\n\n### Provider Auth Options\n\n**1. Unified Billing (keyless)** - pay through Cloudflare, no provider key:\n```typescript\nconst client = new OpenAI({\n  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,\n  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }\n});\n```\nSupports: OpenAI, Anthropic, Google AI Studio\n\n**2. BYOK** - store keys in dashboard (Provider Keys > Add), no key in code\n\n**3. Request Headers** - pass provider key per request:\n```typescript\nconst client = new OpenAI({\n  apiKey: YOUR_KEY\n  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,\n  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }\n});\n```\n\n## API Token Permissions\n\n- **Gateway management:** AI Gateway - Read + Edit\n- **Gateway access:** AI Gateway - Read (minimum)\n\n## Gateway Management API\n\n```bash\n# List\ncurl https://api.cloudflare.com/client/v4/accounts/{account_id}/ai-gateway/gateways \\\n  -H \"Authorization: Bearer $CF_API_TOKEN\"\n\n# Get\ncurl .../gateways/{gateway_id}\n\n# Update\ncurl -X PUT .../gateways/{gateway_id} \\\n  -d '{\"cache_ttl\":7200,\"rate_limiting_limit\":200}'\n\n# Delete\ncurl -X DELETE .../gateways/{gateway_id}\n```\n\n## Getting IDs\n\n- **Account ID:** Dashboard > Overview > Copy\n- **Gateway ID:** AI Gateway > Gateway name column\n\n## Python Example\n\n```python\nfrom openai import OpenAI\nimport os\n\nclient = OpenAI(\n    api_key=YOUR_KEY\n    base_url=f\"https://gateway.ai.cloudflare.com/v1/{os.environ['CF_ACCOUNT_ID']}/{os.environ['GATEWAY_ID']}/openai\",\n    default_headers={\"cf-aig-authorization\": f\"Bearer {os.environ['CF_API_TOKEN']}\"}\n)\n```\n\n## Best Practices\n\n1. **Always authenticate gateways in production**\n2. **Use BYOK or unified billing** - secrets out of code\n3. **Environment-specific gateways** - separate dev/staging/prod\n4. **Set rate limits** - prevent runaway costs\n5. **Enable logging** - track usage, debug issues\n\n## references/ai-gateway/dynamic-routing.md (verbatim)\n\n# Dynamic Routing\n\nConfigure complex routing in dashboard without code changes. Use route names instead of model names.\n\n## Usage\n\n```typescript\nconst response = await client.chat.completions.create({\n  model: 'dynamic/smart-chat', // Route name from dashboard\n  messages: [{ role: 'user', content: 'Hello!' }]\n});\n```\n\n## Node Types\n\n| Node | Purpose | Use Case |\n|------|---------|----------|\n| **Conditional** | Branch on metadata | Paid vs free users, geo routing |\n| **Percentage** | A/B split traffic | Model testing, gradual rollouts |\n| **Rate Limit** | Enforce quotas | Per-user/team limits |\n| **Budget Limit** | Cost quotas | Per-user spending caps |\n| **Model** | Call provider | Final destination |\n\n## Metadata\n\nPass via header (max 5 entries, flat only):\n```typescript\nheaders: {\n  'cf-aig-metadata': JSON.stringify({\n    userId: 'user-123',\n    tier: 'pro',\n    region: 'us-east'\n  })\n}\n```\n\n## Common Patterns\n\n**Multi-model fallback:**\n```\nStart → GPT-4 → On error: Claude → On error: Llama\n```\n\n**Tiered access:**\n```\nConditional: tier == 'enterprise' → GPT-4 (no limit)\nConditional: tier == 'pro' → Rate Limit 1000/hr → GPT-4o\nConditional: tier == 'free' → Rate Limit 10/hr → GPT-4o-mini\n```\n\n**Gradual rollout:**\n```\nPercentage: 10% → New model, 90% → Old model\n```\n\n**Cost-based fallback:**\n```\nBudget Limit: $100/day per teamId\n  < 80%: GPT-4\n  >= 80%: GPT-4o-mini\n  >= 100%: Error\n```\n\n## Version Management\n\n- Save changes as new version\n- Test with `model: 'dynamic/route@v2'`\n- Roll back by deploying previous version\n\n## Monitoring\n\nDashboard → Gateway → Dynamic Routes:\n- Request count per path\n- Success/error rates\n- Latency/cost by path\n\n## Limitations\n\n- Max 5 metadata entries\n- Values: string/number/boolean/null only\n- No nested objects\n- Route names: alphanumeric + hyphens\n\n## references/ai-gateway/features.md (verbatim)\n\n# Features & Capabilities\n\n## Caching\n\nDashboard: Settings → Cache Responses → Enable\n\n```typescript\n// Custom TTL (1 hour)\nheaders: { 'cf-aig-cache-ttl': '3600' }\n\n// Skip cache\nheaders: { 'cf-aig-skip-cache': 'true' }\n\n// Custom cache key\nheaders: { 'cf-aig-cache-key': 'greeting-en' }\n```\n\n**Limits:** TTL 60s - 30 days. **Does NOT work with streaming.**\n\n## Rate Limiting\n\nDashboard: Settings → Rate-limiting → Enable\n\n- **Fixed window:** Resets at intervals\n- **Sliding window:** Rolling window (more accurate)\n- Returns `429` when exceeded\n\n## Guardrails\n\nDashboard: Settings → Guardrails → Enable\n\nFilter prompts/responses for inappropriate content. Actions: Flag (log) or Block (reject).\n\n## Data Loss Prevention (DLP)\n\nDashboard: Settings → DLP → Enable\n\nDetect PII (emails, SSNs, credit cards). Actions: Flag, Block, or Redact.\n\n## Billing Modes\n\n| Mode | Description | Setup |\n|------|-------------|-------|\n| **Unified Billing** | Pay through Cloudflare, no provider keys | Use `cf-aig-authorization` header only |\n| **BYOK** | Store provider keys in dashboard | Add keys in Provider Keys section |\n| **Pass-through** | Send provider key with each request | Include provider's auth header |\n\n## Zero Data Retention\n\nDashboard: Settings → Privacy → Zero Data Retention\n\nNo prompts/responses stored. Request counts and costs still tracked.\n\n## Logging\n\nDashboard: Settings → Logs → Enable (up to 10M logs)\n\nEach entry: prompt, response, provider, model, tokens, cost, duration, cache status, metadata.\n\n```typescript\n// Skip logging for request\nheaders: { 'cf-aig-collect-log': 'false' }\n```\n\n**Export:** Use Logpush to S3, GCS, Datadog, Splunk, etc.\n\n## Custom Cost Tracking\n\nFor models not in Cloudflare's pricing database:\n\nDashboard: Gateway → Settings → Custom Costs\n\nOr via API: set `model`, `input_cost`, `output_cost`.\n\n## Supported Providers (22+)\n\n| Provider | Unified API | Notes |\n|----------|-------------|-------|\n| OpenAI | `openai/gpt-4o` | Full support |\n| Anthropic | `anthropic/claude-sonnet-4-5` | Full support |\n| Google AI | `google-ai-studio/gemini-2.0-flash` | Full support |\n| Workers AI | `workersai/@cf/meta/llama-3` | Native |\n| Azure OpenAI | `azure-openai/*` | Deployment names |\n| AWS Bedrock | Provider endpoint only | `/bedrock/*` |\n| Groq | `groq/*` | Fast inference |\n| Mistral, Cohere, Perplexity, xAI, DeepSeek, Cerebras | Full support | - |\n\n## Best Practices\n\n1. Enable caching for deterministic prompts\n2. Set rate limits to prevent abuse\n3. Use guardrails for user-facing AI\n4. Enable DLP for sensitive data\n5. Use unified billing or BYOK for simpler key management\n6. Enable logging for debugging\n7. Use zero data retention when privacy required\n\n## references/ai-gateway/sdk-integration.md (verbatim)\n\n> 4 placeholder credentials shortened to pass the site's secret filter.\n\n# AI Gateway SDK Integration\n\n## Vercel AI SDK (Recommended)\n\n```typescript\nimport { createAiGateway } from 'ai-gateway-provider';\nimport { createOpenAI } from '@ai-sdk/openai';\nimport { generateText } from 'ai';\n\nconst gateway = createAiGateway({\n  accountId: process.env.CF_ACCOUNT_ID,\n  gateway: process.env.CF_GATEWAY_ID,\n  apiKey: YOUR_KEY // Optional for auth gateways\n});\n\nconst openai = createOpenAI({ apiKey: YOUR_KEY });\n\n// Single model\nconst { text } = await generateText({\n  model: gateway(openai('gpt-4o')),\n  prompt: 'Hello'\n});\n\n// Automatic fallback array\nconst { text } = await generateText({\n  model: gateway([\n    openai('gpt-4o'),\n    anthropic('claude-sonnet-4-5'),\n    openai('gpt-4o-mini')\n  ]),\n  prompt: 'Complex task'\n});\n```\n\n### Options\n\n```typescript\nmodel: gateway(openai('gpt-4o'), {\n  cacheKey: 'my-key',\n  cacheTtl: 3600,\n  metadata: { userId: 'u123', team: 'eng' }, // Max 5 entries\n  retries: { maxAttempts: 3, backoff: 'exponential' }\n})\n```\n\n## OpenAI SDK\n\n```typescript\nconst client = new OpenAI({\n  apiKey: YOUR_KEY\n  baseURL: `https://gateway.ai.cloudflare.com/v1/${accountId}/${gatewayId}/openai`,\n  defaultHeaders: { 'cf-aig-authorization': `Bearer ${cfToken}` }\n});\n\n// Unified API -
