Reviews and authors Cloudflare Workers code against production best practices. Load when writing new Workers, reviewing Worker code, configuring wrangler.jsonc, or checking for common Workers anti-patterns (streaming, floating promises, global state, secrets, bindings, observability). Biases towards retrieval from Cloudflare docs over pre-trained knowledge.
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
Your knowledge of Cloudflare Workers APIs, types, and configuration may be outdated. **Prefer retrieval over pre-training** for any Workers code task - writing or reviewing. ## Retrieval Sources Fetch the **latest** versions before writing or reviewing Workers code. Do not rely on baked-in knowledge for API signatures, config fields, or binding shapes. | Source | How to retrieve | Use for | |--------|----------------|---------| | Workers best practices | Fetch `https://developers.cloudflare.com/workers/best-practices/workers-best-practices/` | Canonical rules, patterns, anti-patterns | | Workers types | See `references/review.md` for retrieval steps | API signatures, handler types, binding types | | Wrangler config schema | `node_modules/wrangler/config-schema.json` | Config fields, binding shapes, allowed values | | Cloudflare docs | Search tool or `https://developers.cloudflare.com/workers/` | API reference, compatibility dates/flags | ## FIRST: Fetch Latest References Before reviewing or writing Workers code, retrieve the current best practices page and relevant type definitions. If the project's `node_modules` has an older version, **prefer the latest published version**. …

How to install
mdr add d-padmanabhan/agent-engineering-handbook/workers-best-practices@sha256:f0e7f22cd5a10858The line at the top of this page pins the label git:20260824.a419591, 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.
