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.

Install

Download the skill as a ZIP:
https://autogineer.com/agent-skills/openai/cloudflare/download

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

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

Documentation by Cloudflare

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.

Source	How to retrieve	Use for
Cloudflare docs	Search `https://developers.cloudflare.com/` directly	Limits, pricing, API reference, compatibility dates/flags
Workers types	`npm pack @cloudflare/workers-types` or check `node_modules`	Type signatures, binding shapes, handler types
Wrangler config schema	`node_modules/wrangler/config-schema.json`	Config fields, binding shapes, allowed values
Product changelogs	`https://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.

Tunnel Networking

Connectivity Requirements

Outbound Ports

Cloudflared requires outbound access on:

Port	Protocol	Purpose	Required
7844	TCP/UDP	Primary tunnel protocol (QUIC)	Yes
443	TCP	Fallback (HTTP/2)	Yes

Network path:

cloudflared → edge.argotunnel.com:7844 (preferred)
cloudflared → region.argotunnel.com:443 (fallback)

Firewall Rules

Minimal (Production)

# Outbound only
ALLOW tcp/udp 7844 to *.argotunnel.com
ALLOW tcp 443 to *.argotunnel.com

Full (Recommended)

# Tunnel connectivity
ALLOW tcp/udp 7844 to *.argotunnel.com
ALLOW tcp 443 to *.argotunnel.com

# API access (for token-based tunnels)
ALLOW tcp 443 to api.cloudflare.com

# Updates (optional)
ALLOW tcp 443 to github.com
ALLOW tcp 443 to objects.githubusercontent.com

IP Ranges

Cloudflare Anycast IPs (tunnel endpoints):

# IPv4
198.41.192.0/24
198.41.200.0/24

# IPv6
2606:4700::/32

Note: Use DNS resolution for *.argotunnel.com rather than hardcoding IPs. Cloudflare may add edge locations.

Pre-Flight Check

Test connectivity before deploying:

# Test DNS resolution
dig edge.argotunnel.com +short

# Test port 7844 (QUIC/UDP)
nc -zvu edge.argotunnel.com 7844

# Test port 443 (HTTP/2 fallback)
nc -zv edge.argotunnel.com 443

# Test with cloudflared
cloudflared tunnel --loglevel debug run my-tunnel
# Look for "Registered tunnel connection"

Common Connectivity Errors

Error	Cause	Solution
"no such host"	DNS blocked	Allow port 53 UDP/TCP
"context deadline exceeded"	Port 7844 blocked	Allow UDP/TCP 7844
"TLS handshake timeout"	Port 443 blocked	Allow TCP 443, disable SSL inspection

Protocol Selection

Cloudflared automatically selects protocol:

Protocol	Port	Priority	Use Case
QUIC	7844 UDP	1st (preferred)	Low latency, best performance
HTTP/2	443 TCP	2nd (fallback)	QUIC blocked by firewall

Force HTTP/2 fallback:

cloudflared tunnel --protocol http2 run my-tunnel

Verify active protocol:

cloudflared tunnel info my-tunnel
# Shows "connections" with protocol type

Private Network Routing

WARP Client Requirements

Users accessing private IPs via WARP need:

# Outbound (WARP client)
ALLOW udp 500,4500 to 162.159.*.* (IPsec)
ALLOW udp 2408 to 162.159.*.* (WireGuard)
ALLOW tcp 443 to *.cloudflareclient.com

Split Tunnel Configuration

Route only private networks through tunnel:

# warp-routing config
warp-routing:
  enabled: true

# Add specific routes
cloudflared tunnel route ip add 10.0.0.0/8 my-tunnel
cloudflared tunnel route ip add 172.16.0.0/12 my-tunnel
cloudflared tunnel route ip add 192.168.0.0/16 my-tunnel

WARP users can access these IPs without VPN.

Network Diagnostics

Connection Diagnostics

# Check edge selection and connection health
cloudflared tunnel info my-tunnel --output json | jq '.connections[]'

# Enable metrics endpoint
cloudflared tunnel --metrics localhost:9090 run my-tunnel
curl localhost:9090/metrics | grep cloudflared_tunnel

# Test latency
curl -w "time_total: %{time_total}\n" -o /dev/null https://myapp.example.com

Corporate Network Considerations

Cloudflared honors proxy environment variables (HTTP_PROXY, HTTPS_PROXY, NO_PROXY).

If corporate proxy intercepts TLS, add corporate root CA to system trust store.

Bandwidth and Rate Limits

Limit	Value	Notes
Request size	100 MB	Single HTTP request
Upload speed	No hard limit	Governed by network/plan
Concurrent connections	1000 per tunnel	Across all replicas
Requests per second	No limit	Subject to DDoS detection

Large file transfers: Use R2 or Workers with chunked uploads instead of streaming through tunnel.
