Cloudflare Platform Skill

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

How to Use This Skill

Reference File Structure

Each product in ./references/<product>/ contains a README.md as the entry point, which may be structured in one of two ways:

Multi-file format (5 files):

File	Purpose	When to Read
README.md	Overview, when to use, getting started	Always read first
api.md	Runtime API, types, method signatures	Writing code
configuration.md	wrangler.toml, bindings, setup	Configuring a project
patterns.md	Common patterns, best practices	Implementation guidance
gotchas.md	Pitfalls, limitations, edge cases	Debugging, avoiding mistakes

Single-file format: All information consolidated in README.md.

Reading Order

1. Start with README.md
2. Then read additional files relevant to your task (if multi-file format):
   • Building feature → api.md + patterns.md
   • Setting up project → configuration.md
   • Troubleshooting → gotchas.md

Example Paths

./references/workflows/README.md         # Start here for Workflows
./references/workflows/api.md            # Workflow class, step methods
./references/durable-objects/gotchas.md  # DO limitations
./references/workers-ai/README.md        # Single-file - all Workers AI docs

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/

"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/

"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/
└─ 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 infrastructure-as-code"

Need IaC?
├─ Pulumi → pulumi/
├─ Terraform → terraform/
└─ Direct API → api/
