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

Cloudflare Deploy provides a centralized framework for developers to build, host, and manage projects on Cloudflare. It covers the entire ecosystem, including serverless compute (Workers), full-stack web hosting (Pages), persistent storage (D1, R2, KV), and AI-powered agent development. The skill includes decision trees to help select the right product for specific needs, authentication guidance, and troubleshooting steps for deployment issues.

What it does

  • Provides decision trees to select the appropriate Cloudflare product for compute, storage, AI, or networking.
  • Offers guidance on authenticating with the Cloudflare platform via CLI or CI/CD.
  • Includes a comprehensive product index for quick reference to documentation.
  • Provides specific patterns and API references for building stateful AI agents using the Agents SDK.
  • Offers troubleshooting steps for network-related deployment failures.
  • Supports infrastructure-as-code integration with tools like Pulumi and Terraform.

When to use it

  • When you need to deploy, host, or publish a project to Cloudflare.
  • When you are unsure which Cloudflare service (e.g., Workers vs. Pages) best fits your application requirements.
  • When you need to build stateful, globally distributed AI agents.
  • When you encounter network errors or timeouts during the deployment process.
  • When setting up persistent storage or database solutions within the Cloudflare ecosystem.

Advantages

  • Consolidates fragmented documentation into a single, navigable resource.
  • Simplifies product selection through clear, use-case-driven decision trees.
  • Provides actionable code patterns for complex tasks like AI agent development.
  • Addresses common deployment friction points like authentication and network sandboxing.

Usage examples

“I need to deploy a full-stack web application to Cloudflare. Which service should I use?”
The agent will guide you to use Cloudflare Pages for full-stack web apps with Git-based deployments.
“How do I build an AI chat agent on Cloudflare?”
The agent will provide the Agents SDK reference, including the AIChatAgent class and examples for streaming responses and managing message history.
“My deployment is failing with a network timeout error. What should I do?”
The agent will advise you to rerun the deployment command with the sandbox_permissions=require_escalated flag to bypass network restrictions.
“How do I store relational data for my worker?”
The agent will recommend using D1 for SQLite-based relational storage or Hyperdrive for connecting to existing Postgres/MySQL databases.

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");
SendEmail Limits
IssueLimitSolution
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
