cloudflare-workers-expert

cloudflare-workers-expert is a skill for Cursor from roedyrustam/vibes-plug. It costs 79 tokens per session (3,294 once invoked), scanned A, original, MIT.

A guide to building applications on Cloudflare Workers, a serverless platform that runs code at Cloudflare's network edge. It covers related storage, database, messaging, state, and AI services in that ecosystem.

In plain words
What is it for?
Use it to build serverless APIs and applications, store data in D1, KV, or R2, process asynchronous work with Queues, keep state with Durable Objects, connect to databases, or run AI inference at the edge.
Why use it?
It helps choose and connect Cloudflare services without managing traditional servers. It also explains how to develop and deploy these edge applications with the Wrangler command-line tool.

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-expert scanned grade A with 1 finding 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 2d ago.

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.

Cloudflare Workers Ecosystem Expert (2026 Edition)

English | Bahasa Indonesia

English

Orchestration & Integration

Connects and orchestrates with domain skills:

  • Edge Backend & APIs: js-backend-expert (Hono v4 on Workers, V8 isolates), api-design-expert (edge REST & RPC endpoints), and sse-websocket-streaming-expert (Durable Objects WebSockets).
  • Edge Storage & DBs: database-orm-expert (Drizzle with D1, Hyperdrive pooling), file-upload-media-expert (R2 presigned URLs), and vector-db-rag-expert (Vectorize & Workers AI).
  • Frontend & Cloud: cloud-hosting-expert (custom domains, CDN rules), senior-frontend (Workers Static Assets), and anti-slop (clean edge architecture without node:fs polyfill traps).
  • Lifecycle & DevOps: ci-cd-devops-architect (GitHub Actions Wrangler deployments), brainstorming, and zero-to-prod-orchestrator (Phase 4: Backend & APIs).

Description

Expert guide for building full-stack edge applications using the Cloudflare Workers ecosystem. Covers Workers runtime, D1 (SQLite at edge), KV (key-value store), R2 (S3-compatible object storage), Queues (message queues), Durable Objects (stateful edge), Hyperdrive (database connection pooling), Workers AI (inference at edge), and Wrangler CLI for development and deployment.

Trigger Conditions

  • Building serverless edge applications on Cloudflare Workers.
  • Using D1 as an edge SQLite database.
  • Storing files with R2 (S3-compatible, zero egress fees).
  • Implementing KV for distributed key-value caching.
  • Building stateful applications with Durable Objects.
  • Setting up Queues for async job processing at the edge.
  • Connecting to external databases via Hyperdrive connection pooling.
  • Running AI inference at the edge with Workers AI.
  • Deploying with Wrangler CLI and wrangler.toml configuration.
  • Using Hono v4 as the web framework on Workers.
