cloudflare-workers

cloudflare-workers is a skill for Claude Code, Codex from ashish7802/awesome-api-skills. It costs 0 tokens per session (650 once invoked), scanned A, original, MIT.

A platform for running serverless JavaScript applications close to users around the world. Its Workers run without managing traditional servers, while KV and Durable Objects provide ways to keep data at the edge.

In plain words
What is it for?
Use it to build and deploy globally distributed serverless applications, run code near users, and add edge storage with Cloudflare KV or Durable Objects.
Why use it?
It removes the need to provision and maintain application servers for these workloads. The guidance addresses the platform's stateless design and how to choose storage for different needs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloudflare-workers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/worker.ts), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Quick Start

Workers run V8 isolates, meaning there are virtually zero cold starts compared to AWS Lambda. Your code executes physically close to the user in hundreds of data centers globally.

npm create cloudflare@latest

Production Patterns

KV and Durable Objects

Workers are stateless. To persist data at the edge, use Cloudflare KV for read-heavy eventual consistency, or Durable Objects for strongly consistent transactional state (like WebSockets or counters).

Architecture & Scaling

Web Standard APIs

Workers do not run Node.js (though compatibility is improving). You must use Web Standard APIs (fetch, Request, Response, crypto.subtle). Avoid libraries that depend heavily on fs or native Node C++ bindings.

Error Recovery

Workers have strict CPU time limits (e.g., 10-50ms). Doing heavy CPU processing will cause the worker to be killed. Offload heavy processing to traditional servers or use Cloudflare Queues.

Security Notes

Use wrangler secret put to securely store API keys. These are injected into the env object passed to your fetch handler, ensuring secrets never touch the codebase.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
