Author or review Cloudflare Workers code for Workers-specific runtime, binding, streaming, concurrency, lifecycle, and configuration mistakes. Use when the user explicitly asks for Workers best-practice review or when implementing a new Worker entrypoint or binding boundary. Do not trigger for generic TypeScript review, ordinary application logic, deployment operations, or product selection.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Workers Best Practices Retrieve current Cloudflare docs, installed Workers types, and the project's Wrangler schema before asserting an API signature or configuration rule. Load references selectively: - [review.md](references/review.md) for a structured Workers review and current type/config retrieval. - [rules.md](references/rules.md) for examples of specific runtime patterns. ## Inspect the Workers boundary Read the full affected entrypoint, binding types, Wrangler environment, and the callers of changed handlers. Check only Workers-specific risks supported by the code: - binding names and generated types match the selected environment; - secrets are not stored in source or ordinary `vars`; - request-scoped mutable state does not leak through module globals; - request and response bodies are streamed when their size is not safely bounded; - every promise is awaited, returned, deliberately detached with `waitUntil`, or explicitly discarded when safe; - platform base classes use their current inheritance and `this.env` contract; - Cloudflare services use bindings or service bindings when those are the intended application boundary; and …

How to install
mdr add swyxio/skills/workers-best-practices@sha256:8b117cbde290879eThe line at the top of this page pins the label git:20261001.7a57f05, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
