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Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated.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 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)
