Deploy applications and infrastructure to Cloudflare using Workers, Pages, and related platform services. Use when the user asks to deploy, host, publish, or set up a project on Cloudflare.
— the description by OpenAI

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The Cloudflare Deploy skill serves as a centralized hub for developers working within the Cloudflare ecosystem. It provides structured decision trees to help users select the appropriate Cloudflare product—ranging from compute and storage to AI and security—and offers guidance on authentication, deployment, and troubleshooting. The skill includes specific references for building stateful, distributed AI agents using the Cloudflare Agents SDK, covering lifecycle hooks, state management, and SQL integration.

What it does

  • Provides decision trees to select the right Cloudflare product for compute, storage, AI, or networking needs.
  • Offers guidance on authentication using Wrangler for local and CI/CD environments.
  • Includes detailed documentation for building stateful AI agents with the Cloudflare Agents SDK.
  • Supports infrastructure-as-code integration via Pulumi and Terraform.
  • Provides troubleshooting steps for network-related deployment failures.
  • Maps specific use cases to relevant product references and technical documentation.

When to use it

  • When you need to deploy, host, or publish a project on Cloudflare.
  • When you are unsure which Cloudflare product best fits your compute, storage, or AI requirements.
  • When building stateful AI agents that require persistent memory and real-time connections.
  • When you need to configure security, networking, or media optimization services on Cloudflare.
  • When troubleshooting deployment timeouts or network connectivity issues.

Advantages

  • Consolidates fragmented documentation into a single, navigable resource.
  • Simplifies product selection through clear, logic-based decision trees.
  • Provides ready-to-use code patterns for complex tasks like AI agent development.
  • Addresses common operational hurdles like authentication and network sandboxing.

Usage examples

“I need to deploy a full-stack web application to Cloudflare. Which product should I use?”
The agent will guide you to use Cloudflare Pages for Git-based deployments and provide the necessary steps to get started.
“How do I build a stateful AI chat agent on Cloudflare?”
The agent will provide the AIChatAgent class structure, explain how to manage message history, and show how to integrate with Workers AI.
“My deployment is failing with a network timeout. What should I do?”
The agent will recommend rerunning the deployment with escalated permissions using the sandbox_permissions=require_escalated flag.

Install

Documentation by OpenAI

Cloudflare Deploy

Consolidated skill for building on the Cloudflare platform. Use decision trees below to find the right product, then load detailed references.

Prerequisites

  • When sandboxing blocks the deployment network calls, rerun with sandbox_permissions=require_escalated.

  • The deployment might take a few minutes. Use appropriate timeout values.

Authentication (Required Before Deploy)

Verify auth before wrangler deploy, wrangler pages deploy, or npm run deploy:

npx wrangler whoami    # Shows account if authenticated

Not authenticated? → references/wrangler/auth.md

  • Interactive/local: wrangler login (one-time OAuth)

  • CI/CD: Set CLOUDFLARE_API_TOKEN env var

Troubleshooting

Escalated Network Access

If deployment fails due to network issues (timeouts, DNS errors, connection resets), rerun the deploy with escalated permissions (use sandbox_permissions=require_escalated). The deploy requires escalated network access when sandbox networking blocks outbound requests.

Example guidance to the user:

The deploy needs escalated network access to deploy to Cloudflare. I can rerun the command with escalated permissions—want me to proceed?

Gotchas & Troubleshooting

Critical Pitfalls

Stream Consumption (MOST COMMON)

Problem: "stream already consumed" or worker hangs

Cause: message.raw is ReadableStream - consume once only

Solution:

// ❌ WRONG
const email1 = await parser.parse(await message.raw.arrayBuffer());
const email2 = await parser.parse(await message.raw.arrayBuffer()); // FAILS

// ✅ CORRECT
const raw = await message.raw.arrayBuffer();
const email = await parser.parse(raw);

Consume message.raw immediately before any async operations.

Destination Verification

Problem: Emails not forwarding

Cause: Destination unverified

Solution: Add destination, check inbox for verification email, click link. Verify status: GET /zones/{id}/email/routing/addresses

Mail Authentication

Problem: Legitimate emails rejected

Cause: Missing SPF/DKIM/DMARC on sender domain

Solution: Configure sender DNS:

example.com. IN TXT "v=spf1 include:_spf.example.com ~all"
selector._domainkey.example.com. IN TXT "v=DKIM1; k=rsa; p=..."
_dmarc.example.com. IN TXT "v=DMARC1; p=quarantine"
Envelope vs Header

Problem: Filtering on wrong address

Solution:

// Routing/auth: envelope
if (message.from === "[email protected]") { }

// Display: headers
const display = message.headers.get("from");

From domainMust ownUse Email Routing domain
Volume~100/min FreeUpgrade or throttle
AttachmentsNot supportedLink to R2
TypeTransactionalNo bulk

Common Errors

CPU Time Exceeded

Cause: Heavy parsing, large emails

Solution:

const size = parseInt(message.headers.get("content-length") || "0") / 1024 / 1024;
if (size > 20) {
  message.setReject("Too large");
  return;
}

ctx.waitUntil(expensiveWork());
await message.forward("[email protected]");
Rule Not Triggering

Causes: Priority conflict, matcher error, catch-all override

Solution: Check priority (lower=first), verify exact match, confirm destination verified

Undefined Property

Cause: Missing header

Solution:

// ❌ WRONG
const subj = message.headers.get("subject").toLowerCase();

// ✅ CORRECT
const subj = message.headers.get("subject")?.toLowerCase() || "";

Debugging

Local
npx wrangler dev

curl -X POST 'http://localhost:8787/__email' \
  --header 'content-type: message/rfc822' \
  --data 'From: [email protected]
To: [email protected]
Subject: Test

Body'
Production
npx wrangler tail
Pattern
export default {
  async email(message, env, ctx) {
    try {
      console.log("From:", message.from);
      await process(message, env);
    } catch (err) {
      console.error(err);
      message.setReject(err.message);
    }
  }
} satisfies ExportedHandler;

Auth Troubleshooting

Check Status
const auth = message.headers.get("authentication-results") || "";
console.log({
  spf: auth.includes("spf=pass"),
  dkim: auth.includes("dkim=pass"),
  dmarc: auth.includes("dmarc=pass")
});

if (!auth.includes("pass")) {
  message.setReject("Failed auth");
  return;
}
SPF Issues

Causes: Forwarding breaks SPF, too many lookups (>10), missing includes

Solution:

; ✅ Good
example.com. IN TXT "v=spf1 include:_spf.google.com ~all"

; ❌ Bad - too many
example.com. IN TXT "v=spf1 include:a.com include:b.com ... ~all"
DMARC Alignment

Cause: From domain must match SPF/DKIM domain

Best Practices

  1. Consume message.raw immediately

  2. Verify destinations

  3. Handle missing headers (?.)

  4. Use envelope for routing

  5. Check spam scores

  6. Test locally first

  7. Use ctx.waitUntil for background work

  8. Size-check early
