From the author

Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task. Biases towards retrieval from Cloudflare docs over pre-trained knowledge.

AutoGineer summary

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

The Cloudflare platform skill provides a centralized resource for developers building on Cloudflare's edge network. It covers the full ecosystem, including compute (Workers, Pages), storage (KV, D1, R2), AI integration (Workers AI, Agents SDK), networking, and security. The skill emphasizes a retrieval-first approach, directing users to official Cloudflare documentation and configuration schemas to ensure accuracy regarding API signatures, limits, and pricing.

What it does

  • Provides decision trees to help select the right Cloudflare product for specific compute, storage, or networking needs.
  • Offers structured references for the Cloudflare Agents SDK, including lifecycle hooks and state management.
  • Guides users on integrating AI models and vector databases into edge applications.
  • Outlines methods for managing infrastructure-as-code using Terraform or Pulumi.
  • Facilitates access to product-specific documentation for security, media, and analytics services.
  • Maintains a directory of developer tools like Wrangler and Miniflare for local development and testing.

When to use it

  • When starting a new project on the Cloudflare platform and needing to choose the appropriate architecture.
  • When implementing stateful AI agents using the Cloudflare Agents SDK.
  • When configuring edge compute, storage bindings, or networking rules.
  • When troubleshooting API limits, configuration errors, or deployment issues.
  • When integrating AI models or vector search into existing edge applications.

Advantages

  • Consolidates a vast ecosystem into a navigable, task-oriented structure.
  • Promotes the use of official, up-to-date documentation over potentially stale training data.
  • Simplifies complex architectural decisions through clear, logic-based decision trees.
  • Provides specific code patterns for advanced features like Durable Objects and AI agents.
  • Supports modern infrastructure-as-code workflows for consistent deployments.

Usage examples

“I need to build a stateful AI chat agent on Cloudflare. How do I start?”
The agent will guide you to use the AIChatAgent class from the Agents SDK, explain how to manage message history, and provide a template for integrating AI models.
“Which storage solution should I use for relational data in my Worker?”
The agent will point you to D1 for SQLite-based relational storage or Hyperdrive for connecting to existing Postgres/MySQL databases.
“How do I expose my local development server to the internet via Cloudflare?”
The agent will provide instructions on using Cloudflare Tunnel to securely connect your local service to the Cloudflare edge.

Cloudflare Platform Skill

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

Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated. Prefer retrieval over pre-training — the references in this skill are starting points, not source of truth.

Retrieval Sources

Fetch the latest information before citing specific numbers, API signatures, or configuration options. Do not rely on baked-in knowledge or these reference files alone.

SourceHow to retrieveUse for
Cloudflare docsSearch https://developers.cloudflare.com/ directlyLimits, pricing, API reference, compatibility dates/flags
Workers typesnpm pack @cloudflare/workers-types or check node_modulesType signatures, binding shapes, handler types
Wrangler config schemanode_modules/wrangler/config-schema.jsonConfig fields, binding shapes, allowed values
Product changelogshttps://developers.cloudflare.com/changelog/Recent changes to limits, features, deprecations

When a reference file and the docs disagree, trust the docs. This is especially important for: numeric limits, pricing tiers, type signatures, and configuration options.

Configuration

Setup and configuration for TCP Sockets in Cloudflare Workers.

Wrangler Configuration

Basic Setup

TCP Sockets are available by default in Workers runtime. No special configuration required in wrangler.jsonc:

{
  "name": "private-network-worker",
  "main": "src/index.ts",
  "compatibility_date": "2025-01-01"
}
Environment Variables

Store connection details as env vars:

{
  "vars": { "DB_HOST": "10.0.1.50", "DB_PORT": "5432" }
}
interface Env { DB_HOST: string; DB_PORT: string; }

export default {
  async fetch(req: Request, env: Env): Promise<Response> {
    const socket = connect({ hostname: env.DB_HOST, port: parseInt(env.DB_PORT) });
  }
};
Per-Environment Configuration
{
  "vars": { "DB_HOST": "localhost" },
  "env": {
    "staging": { "vars": { "DB_HOST": "staging-db.internal.net" } },
    "production": { "vars": { "DB_HOST": "prod-db.internal.net" } }
  }
}

Deploy: wrangler deploy --env staging or wrangler deploy --env production

Integration with Cloudflare Tunnel

To connect Workers to private networks, combine TCP Sockets with Cloudflare Tunnel:

Worker (TCP Socket) → Tunnel hostname → cloudflared → Private Network
Quick Setup

  1. Install cloudflared on a server inside your private network

  2. Create tunnel: cloudflared tunnel create my-private-network

  3. Configure routing in config.yml:

tunnel: <TUNNEL_ID>
credentials-file: /path/to/<TUNNEL_ID>.json
ingress:
  - hostname: db.internal.example.com
    service: tcp://10.0.1.50:5432
  - service: http_status:404  # Required catch-all

  1. Run tunnel: cloudflared tunnel run my-private-network

  2. Connect from Worker:

const socket = connect(
  { hostname: "db.internal.example.com", port: 5432 },  // Tunnel hostname
  { secureTransport: "on" }
);

For detailed Tunnel setup, see Tunnel configuration reference.

Smart Placement Integration

Reduce latency by auto-placing Workers near backends:

{ "placement": { "mode": "smart" } }

Workers automatically relocate closer to TCP socket destinations after observing connection latency. See Smart Placement reference.

Secrets Management

Store sensitive credentials as secrets (not in wrangler.jsonc):

wrangler secret put DB_PASSWORD  # Enter value when prompted

Access in Worker via env.DB_PASSWORD. Use in protocol handshake or authentication.

Local Development

Test with wrangler dev. Note: Local mode may not access private networks. Use public endpoints or mock servers for development:

const config = process.env.NODE_ENV === 'dev'
  ? { hostname: 'localhost', port: 5432 }  // Mock
  : { hostname: 'db.internal.example.com', port: 5432 };  // Production

Connection String Patterns

Parse connection strings to extract host and port:

function parseConnectionString(connStr: string): SocketAddress {
  const url = new URL(connStr); // e.g., "postgres://10.0.1.50:5432/mydb"
  return { hostname: url.hostname, port: parseInt(url.port) || 5432 };
}

Hyperdrive Integration

For PostgreSQL/MySQL, prefer Hyperdrive over raw TCP sockets (includes connection pooling):

{ "hyperdrive": [{ "binding": "DB", "id": "<HYPERDRIVE_ID>" }] }

See Hyperdrive reference for complete setup.

Compatibility

TCP Sockets available in all modern Workers. Use current date: "compatibility_date": "2025-01-01". No special flags required.
