Cloudflare
Workers, Pages, D1, KV, R2, Durable Objects, AI, networking, security — the full Cloudflare platform in one skill.

Deploy a Worker, wire up D1, build a stateful AI agent, protect an API with WAF, stream video — Cloudflare's platform covers an absurd amount of ground, and this skill knows all of it. It handles the full stack: compute (Workers, Pages, Durable Objects), storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), security (WAF, DDoS, Turnstile), networking, media, and infrastructure-as-code with Terraform and Pulumi.
The key thing that makes it genuinely useful: it doesn't guess. Cloudflare ships fast, and limits, API signatures, and config options go stale quickly. This skill pulls current information directly from Cloudflare's docs rather than trusting whatever was baked in at training time. When the docs say something different from what the model thinks it knows, the docs win.
If you're building anything on Cloudflare — whether it's your first Worker or a multi-product architecture with queues, agents, and a CDN in front — this skill gives you a structured guide to the right product for the job and accurate answers when the details matter.

# Cloudflare Platform Skill
Consolidated skill for building on the Cloudflare platform. Use decision trees below to find the right product, then load detailed references.
## Prerequisites
- **Cloudflare account** — You need a [Cloudflare account](https://dash.cloudflare.com/sign-up) to use any Cloudflare platform service.
Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated.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 | `cloudflare-docs` search tool or `https://developers.cloudflare.com/` | 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.
## Quick Decision Trees
### "I need to run code"
```
Need to run code?
├─ Serverless functions at the edge → workers/
├─ Full-stack web app with Git deploys → pages/
├─ Stateful coordination/real-time → durable-objects/
├─ Long-running multi-step jobs → workflows/
├─ Run containers → containers/
├─ Multi-tenant (customers deploy code) → workers-for-platforms/
├─ Scheduled tasks (cron) → cron-triggers/
├─ Lightweight edge logic (modify HTTP) → snippets/
├─ Process Worker execution events (logs/observability) → tail-workers/
└─ Optimize latency to backend infrastructure → smart-placement/
```
### "I need to store data"
```
Need storage?
├─ Key-value (config, sessions, cache) → kv/
├─ Relational SQL → d1/ (SQLite) or hyperdrive/ (existing Postgres/MySQL)
├─ Object/file storage (S3-compatible) → r2/
├─ Message queue (async processing) → queues/
├─ Vector embeddings (AI/semantic search) → vectorize/
├─ Strongly-consistent per-entity state → durable-objects/ (DO storage)
├─ Secrets management → secrets-store/
├─ Streaming ETL to R2 → pipelines/
└─ Persistent cache (long-term retention) → cache-reserve/
```
### "I need AI/ML"
```
Need AI?
├─ Run inference (LLMs, embeddings, images) → workers-ai/
├─ Vector database for RAG/search → vectorize/
├─ Build stateful AI agents → agents-sdk/
├─ Gateway for any AI provider (caching, routing) → ai-gateway/
└─ AI-powered search widget → ai-search/
```
### "I need networking/connectivity"
```
Need networking?
├─ Expose local service to internet → tunnel/
├─ TCP/UDP proxy (non-HTTP) → spectrum/
├─ WebRTC TURN server → turn/
├─ Private network connectivity → network-interconnect/
├─ Optimize routing → argo-smart-routing/
├─ Optimize latency to backend (not user) → smart-placement/
└─ Real-time video/audio → realtimekit/ or realtime-sfu/
```
### "I need security"
```
Need security?
├─ Web Application Firewall → waf/
├─ DDoS protection → ddos/
├─ Bot detection/management → bot-management/
├─ API protection → api-shield/
├─ CAPTCHA alternative → turnstile/
└─ Credential leak detection → waf/ (managed ruleset)
```
### "I need media/content"
```
Need media?
├─ Image optimization/transformation → images/
├─ Video streaming/encoding → stream/
├─ Browser automation/screenshots → browser-rendering/
└─ Third-party script management → zaraz/
```
### "I need analytics/metrics data"
```
Need analytics?
├─ Query across all Cloudflare products (HTTP, Workers, DNS, etc.) → graphql-api/
├─ Custom high-cardinality metrics from Workers → analytics-engine/
├─ Client-side (RUM) performance data → web-analytics/
├─ Workers Logs and real-time debugging → observability/
└─ Raw logs (Logpush to external tools) → Cloudflare docs
```
### "I need infrastructure-as-code"
```
Need IaC? → pulumi/ (Pulumi), terraform/ (Terraform), or api/ (REST API)
```
