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Your knowledge of Cloudflare APIs, types, limits, and pricing may be outdated.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