Use when optimising Largest Contentful Paint (LCP), reducing render-blocking resource contention, or fine-tuning resource loading order in the critical rendering path.
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
# Use fetchpriority to hint resource loading priority Browsers use internal heuristics to guess resource priority, but they cannot know which image is your LCP candidate. Adding fetchpriority="high" to the LCP image has been shown to reduce LCP by 5–30 % in real-world tests, directly improving Core Web Vitals scores and user-perceived load speed. The attribute costs nothing to add and is the lowest-effort high-impact performance optimisation available today. ## Quick Reference - Add fetchpriority="high" to the LCP image to accelerate Largest Contentful Paint - Add fetchpriority="low" to below-the-fold images that would otherwise compete with critical resources - Use fetchpriority="high" on <link rel="preload"> for critical fonts and CSS - Avoid marking more than one or two resources as high priority — it defeats the purpose ## Check Check whether the LCP image or hero element has fetchpriority="high" and whether any high-priority preload links are missing the attribute. ## Fix Add fetchpriority="high" to the LCP image element and any preloaded critical resources, and fetchpriority="low" to non-critical below-the-fold images. ## Explain …

How to install
mdr add thedaviddias/front-end-checklist/fetchpriority-attribute@sha256:cf7a8e0e3a7b7c87The line at the top of this page pins the label git:20261004.4b0ddb9, 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.
