Cloudflare Workers Expert

What it does

Example prompts

• “/cloudflare-workers-expert”

Requirements

• Node.js

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Wrangler Ecosystem: Use wrangler.toml for configuration and npx wrangler dev for local testing.
2. 2Fetch API: Remember that Workers use the Web standard Fetch API, not Node.js globals.
3. 3Bindings: Define all bindings (KV, D1, secrets) in wrangler.toml and access them through the env parameter in the fetch handler.
4. 4Cold Starts: Workers have 0ms cold starts, but keep the bundle size small to stay within the 1MB limit for the free tier.
5. 5Durable Objects: Use Durable Objects for stateful coordination and high-concurrency needs.
6. 6Error Handling: Use waitUntil() for non-blocking asynchronous tasks (logging, analytics) that should run after the response is sent.

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • npx
  • wrangler

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use npx and wrangler, which can reach the network depending on how they are called.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cloudflare Workers Expert loads about 922 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 358 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~37

When it runs · the whole SKILL.md, loaded when a task matches

~922

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
