From the author

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

Download the skill as a ZIP:

Unzip it into the cross-client skills folder of your project:

mkdir -p .agents/skills && unzip cloudflare-deploy.zip -d .agents/skills

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

Miniflare Limitations

Not supported:

Analytics Engine (use mocks)
Cloudflare Images/Stream
Browser Rendering API
Tail Workers
Workers for Platforms (partial support)

Behavior differences from production:

Runs workerd locally, not Cloudflare edge
Storage is local (filesystem/memory), not distributed
Request.cf is cached/mocked, not real edge data
Performance differs from edge
Caching implementation may vary slightly

Common Errors

"Cannot find module"

Cause: Module path wrong or modulesRules not configured
Solution:

new Miniflare({
  modules: true,
  modulesRules: [{ type: "ESModule", include: ["**/*.js"] }],
});

"Data not persisting"

Cause: Persist paths are files, not directories
Solution:

kvPersist: "./data/kv",  // Directory, not file

"Cannot run TypeScript"

Cause: Miniflare doesn't transpile TypeScript
Solution: Build first with esbuild/tsc, then run compiled JS

"`request.cf` is undefined"

Cause: CF data not configured
Solution:

new Miniflare({ cf: true }); // Or cf: "./cf.json"

"EADDRINUSE" port conflict

Cause: Multiple instances using same port
Solution: Use dispatchFetch() (no HTTP server) or port: 0 for auto-assign

"Durable Object not found"

Cause: Class export doesn't match config name
Solution:

export class Counter {} // Must match
new Miniflare({ durableObjects: { COUNTER: "Counter" } });

Debugging

Enable verbose logging:

import { Log, LogLevel } from "miniflare";
new Miniflare({ log: new Log(LogLevel.DEBUG) });

Chrome DevTools:

const url = await mf.getInspectorURL();
console.log(`DevTools: ${url}`); // Open in Chrome

Inspect bindings:

const env = await mf.getBindings();
console.log(Object.keys(env));

Verify storage:

const ns = await mf.getKVNamespace("TEST");
const { keys } = await ns.list();

Best Practices

✓ Do:

Use dispatchFetch() for tests (no HTTP server)
In-memory storage for CI (omit persist options)
New instances per test for isolation
Type-safe bindings with interfaces
await mf.dispose() in cleanup

✗ Avoid:

HTTP server in tests
Shared instances without cleanup
Old compatibility dates (use 2026+)

Migration Guides

From Miniflare 2.x to 3+

Breaking changes in v3+:

v2	v3+
`getBindings()` sync	`getBindings()` returns Promise
`ready` is void	`ready` returns `Promise<URL>`
service-worker-mock	Built on workerd
Different options	Restructured constructor

Example migration:

// v2
const bindings = mf.getBindings();
mf.ready; // void

// v3+
const bindings = await mf.getBindings();
const url = await mf.ready; // Promise<URL>

From unstable_dev to Miniflare

// Old (deprecated)
import { unstable_dev } from "wrangler";
const worker = await unstable_dev("src/index.ts");

// New
import { Miniflare } from "miniflare";
const mf = new Miniflare({ scriptPath: "src/index.ts" });

From Wrangler Dev

Miniflare doesn't auto-read wrangler.toml:

// Translate manually:
new Miniflare({
  scriptPath: "dist/worker.js",
  compatibilityDate: "2026-01-01",
  kvNamespaces: ["KV"],
  bindings: { API_KEY: process.env.API_KEY },
});
