What problem does it solve?

This Skill reduces production incidents by reviewing Cloudflare Workers code, configuration, and patterns against up-to-date best practices and anti-patterns.

Core Features & Use Cases

Workers code review against production best practices: flags common issues like floating promises, global request state, incorrect binding access patterns, and unsafe response handling.
Wrangler configuration and types validation guidance: ensures compatibility dates, observability settings, secrets usage, and binding-code consistency are correct by validating against the wrangler config schema and generated types.
Security-focused review checks for Workers: highlights unsafe token generation, insecure randomness, and weak error handling patterns while recommending Cloudflare-aligned approaches.

Quick Start

Ask your AI to review your Worker’s fetch handler and wrangler.jsonc for streaming correctness, floating promises, binding access usage, and secrets/observability configuration.

What are common anti-patterns when writing Cloudflare Workers?▼

Common Cloudflare Workers anti-patterns include floating promises, module-level request state, unsafe token generation, insecure randomness, and incorrect binding access patterns. Validating compatibility_date and observability settings helps avoid these production failures.

How do I validate wrangler configuration and types for Cloudflare Workers?▼

Validate wrangler configuration by checking compatibility dates, observability settings, secrets usage, and binding-code consistency against the wrangler config schema and generated types to ensure safe Cloudflare Workers deployment.

Does my Cloudflare Worker need specific configuration for streaming and background execution?▼

Cloudflare Workers require specific configuration for streaming and background execution to prevent production failures. You must validate compatibility_date, bindings, and async execution patterns against current best practices for safe operations.

Why does my Cloudflare Worker have incorrect ctx or env usage?▼

Incorrect ctx or env usage in Cloudflare Workers often stems from improper binding access patterns or module-level request state. Reviewing your fetch handler against type schema sources and best practices resolves these configuration mismatches.
