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:

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 Gotchas

Common Errors

"Error 1016 (Origin DNS Error)"

Cause: Tunnel not running or not connected Solution:

cloudflared tunnel info my-tunnel     # Check status
ps aux | grep cloudflared             # Verify running
journalctl -u cloudflared -n 100      # Check logs

"Self-signed certificate rejected"

Cause: Origin using self-signed certificate Solution:

originRequest:
  noTLSVerify: true      # Dev only
  caPool: /path/to/ca.pem  # Custom CA

"Connection timeout"

Cause: Origin slow to respond or timeout settings too low Solution:

originRequest:
  connectTimeout: 60s
  tlsTimeout: 20s
  keepAliveTimeout: 120s

"Tunnel not starting"

Cause: Invalid config, missing credentials, or tunnel doesn't exist Solution:

cloudflared tunnel ingress validate  # Validate config
ls -la ~/.cloudflared/*.json         # Verify credentials
cloudflared tunnel list              # Verify tunnel exists

"Connection already registered"

Cause: Multiple replicas with same connector ID or stale connection Solution:

# Check active connections
cloudflared tunnel info my-tunnel

# Wait 60s for stale connection cleanup, or restart with new connector ID
cloudflared tunnel run my-tunnel

"Tunnel credentials rotated but connections fail"

Cause: Old cloudflared processes using expired credentials Solution:

# Stop all cloudflared processes
pkill cloudflared

# Verify stopped
ps aux | grep cloudflared

# Restart with new credentials
cloudflared tunnel run my-tunnel

Tunnel replicas	1000 per tunnel	Max concurrent
Connection duration	No hard limit	Hours to days
Long-lived connections	May drop during updates	WebSocket, SSH, UDP
Replica registration	~5s TTL	Old replica dropped after 5s no heartbeat
Token rotation grace	24 hours	Old tokens work during grace period

Best Practices

Security

Use token-based tunnels (config source: cloudflare) for centralized control
Enable Access policies for sensitive services
Rotate tunnel credentials regularly
After rotation: stop all old cloudflared processes within 24h grace period
Verify TLS certs (noTLSVerify: false)
Restrict bastion service type

Performance

Run multiple replicas for HA (2-4 typical, load balanced automatically)
Replicas share same tunnel UUID, get unique connector IDs
Place cloudflared close to origin (same network)
Use HTTP/2 for gRPC (http2Origin: true)
Tune keepalive for long-lived connections
Monitor connection counts

Configuration

Use environment variables for secrets
Version control config files
Validate before deploying (cloudflared tunnel ingress validate)
Test rules (cloudflared tunnel ingress rule <URL>)
Document rule order (first match wins)

Operations

Monitor tunnel health in dashboard (shows active replicas)
Set up disconnect alerts (when replica count drops to 0)
Graceful shutdown for config updates
Update replicas in rolling fashion (update 1, wait, update next)
Keep cloudflared updated (1 year support window)
Use --no-autoupdate in prod; control updates manually

Debug Mode

cloudflared tunnel --loglevel debug run my-tunnel
cloudflared tunnel ingress rule https://app.example.com

Migration Strategies

From Ngrok

# Ngrok: ngrok http 8000
# Cloudflare Tunnel:
ingress:
  - hostname: app.example.com
    service: http://localhost:8000
  - service: http_status:404

From VPN

# Replace VPN with private network routing
warp-routing:
  enabled: true

cloudflared tunnel route ip add 10.0.0.0/8 my-tunnel

Users install WARP client instead of VPN.
