Cloudflare Platform Skill (router)

Consolidated skill for building on the Cloudflare platform. First check the Deep-Dive Sub-Skills table below: for those topics the nested skill is the curated source of truth and supersedes the thin references/ stub. Otherwise use the decision trees 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Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated.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.

Deep-Dive Sub-Skills

These nested skills are richer than the matching references/ stub. When the task matches, Read the nested SKILL.md and follow it exactly.

When the task is about…	Read
Building AI agents on Workers: stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, chat/voice agents, browser automation, React hooks	nested/agents-sdk/SKILL.md
Durable Objects: stateful coordination (chat rooms, multiplayer, booking), RPC methods, SQLite storage, alarms, WebSockets, or reviewing DO code	nested/durable-objects/SKILL.md
Sandboxed code execution: AI code interpreters, CI/CD runners, interactive dev environments, running untrusted code, preview URLs	nested/sandbox-sdk/SKILL.md
Transactional email: sending (Workers binding or REST API), Email Routing, Agents SDK email, deliverability/SPF/DKIM/DMARC, wrangler email setup (even simple "add email to my Worker")	nested/cloudflare-email-service/SKILL.md
Wrangler CLI: deploying/developing/managing Workers, KV, R2, D1, Vectorize, Hyperdrive, Workers AI, Containers, Queues, Workflows, Pipelines, Secrets Store	nested/wrangler/SKILL.md
Authoring or reviewing Worker code against production best-practices: streaming, floating promises, global state, secrets, bindings, observability, wrangler.jsonc anti-patterns	nested/workers-best-practices/SKILL.md

For everything else, continue with the decision trees and Product Index below.

Retrieval Sources

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

Fetch the latest information before citing numeric limits, pricing tiers, type signatures, or configuration options. When a reference file and the docs disagree, trust the docs.
