Publish a static site (a folder of HTML/CSS/JS/images/fonts) to Cloudflare and get back a live, shareable URL in seconds. Use when you have a finished static page or site and need to hand someone a link they can open on any device — reports, mockups, one-off landing pages, AI-generated HTML, "give me a link I can share". Runs one packaged command (references/deploy.mjs) built on the Wrangler CLI, which is what Cloudflare's own agent guidance tells agents to use. Deploys permanently to your Cloudflare account when credentials are present, or as a 60-minute claimable preview when they are not — and says plainly which one you got. Bakes an expiry countdown into previews (matched to the real 60-minute limit; --ttl to shorten it), and supports optional server-side six-digit access-code protection with -otp for permanent links only. Unprotected delivery may fall back to a file; protected delivery fails closed.

• Reviewing cache behavior on CDN-backed websites

• Verifying cached responses influenced by headers

Deploy a free VLESS proxy/VPN node on Cloudflare Pages using edgetunnel. Automates code download, UUID generation, Pages deployment, free domain registration (DNSExit), DNS configuration, custom domain binding, and client setup for Shadowrocket/v2rayN/Clash. Uses Cloudflare Pages (not Workers) because Pages supports CNAME-based custom domains from any DNS provider, avoiding the need to host DNS on Cloudflare.

Prefer the focused skill when one fits: agents-sdk for the Agents SDK, durable-objects for Durable Objects, workers-best-practices for reviewing or authoring Worker code, wrangler for CLI commands, sandbox-sdk for sandboxed execution.
