This skill documents the Wrangler CLI for deploying and managing Cloudflare Workers and related services. It instructs running shell commands like `npm install -D wrangler@latest`, managing secrets with `wrangler secret put API_KEY`, and performing network operations such as `wrangler deploy`.

This skill documents building and testing Cloudflare Durable Objects, including examples, wrangler config, and Vitest tests. It includes CLI commands (`npm i -D ...`, `npx vitest`, `wrangler deploy`), secret usage (`wrangler secret put API_KEY`, `env.API_KEY`), and references external docs (`https://developers.cloudflare.com/durable-objects/`).

Analyzes web performance using Chrome DevTools MCP. Measures Core Web Vitals (FCP, LCP, TBT, CLS, Speed Index), identifies render-blocking resources, network dependency chains, layout shifts, caching issues, and accessibility gaps. Use when asked to audit, profile, debug, or optimize page load performance, Lighthouse scores, or site speed.

Build AI agents on Cloudflare Workers using the Agents SDK. Load when creating stateful agents, durable workflows, real-time WebSocket apps, scheduled tasks, MCP servers, or chat applications. Covers Agent class, state management, callable RPC, Workflows integration, and React hooks.

Builds Cloudflare AI agents with stateful Durable Objects, WebSocket chat, scheduled tasks, and deployment examples. Includes explicit external network calls to `https://api.weather.com/...`, `http://agent/task`, and `https://github-mcp.example.com/sse`, uses environment bindings like `GITHUB_TOKEN`, `AI`, `VECTORIZE`, and shows CLI commands such as `npm start` and `npx wrangler deploy`.

Builds remote MCP (Model Context Protocol) servers on Cloudflare Workers with tools, OAuth authentication, and production deployment. Generates server code, configures auth providers, and deploys to Workers. Use when: user wants to "build MCP server", "create MCP tools", "remote MCP", "deploy MCP", add "OAuth to MCP", or mentions Model Context Protocol on Cloudflare. Also triggers on "MCP authentication" or "MCP deployment".

This skill documents the Cloudflare Sandbox SDK for building and running isolated code sandboxes. It explicitly instructs executing shell commands (e.g., `npm install @cloudflare/sandbox`, `docker info`, `await sandbox.exec('python --version')`) and to fetch external docs (`https://developers.cloudflare.com/sandbox/`).

This skill is a Cloudflare platform reference covering Workers, AI, storage, networking, and IaC. It includes examples that instruct running commands like `npx wrangler`/`curl`, using secrets such as `OPENAI_API_KEY`/`CLOUDFLARE_API_TOKEN`, and calling endpoints like `https://api.cloudflare.com/client/v4` and `https://gateway.ai.cloudflare.com`.

This skill reviews and authors Cloudflare Workers code and instructs retrieving the latest docs and types (e.g., `https://developers.cloudflare.com/workers/best-practices/workers-best-practices/`). It explicitly directs running shell setup commands into `/tmp` (e.g., `npm pack` into `/tmp/workers-types-latest`) and uses secret management via `wrangler secret put`.
