What problem does it solve? Cloudflare Workers APIs, types, and wrangler configuration change frequently, so code written from stale knowledge often contains wrong binding access patterns, outdated config fields, and anti-patterns like floating promises or buffered response bodies. This Skill grounds Workers authoring and review in retrieved, current references instead of outdated training data. ## Core Features & Use Cases - Best-Practice Rules: Applies canonical rules for streaming, waitUntil, bindings, secrets, observability, security, and testing when writing or refactoring Worker code. - Structured Code Review: Runs a retrieval-first review process covering type validation, wrangler config validation, serialization boundaries, and severity-ranked findings with file and line evidence. - Config Validation: Checks wrangler.jsonc for compatibility_date freshness, nodejs_compat, binding-code consistency, Durable Object migrations, and secrets stored in vars. - Use Case: When reviewing a pull request that adds a Queue producer to a Worker, the Skill fetches the latest @cloudflare/workers-types, verifies the Env binding types and handler signatures, and flags issues like any on bindings or non-serializable queue message bodies. ## Quick Start Ask the agent to review your Worker code and wrangler.jsonc against Cloudflare Workers best practices, fetching the latest types before flagging anything.
