Use when auditing slow page loads, heavy assets, or rendering delays related to Minimize critical request chains. Verify the actual bottleneck in DevTools, Lighthouse, or field data before recommending changes.
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
# Minimize critical request chains Long chains of dependent requests delay the initial rendering of the page, as each resource must wait for its parent to be fetched and processed. ## Quick Reference - Reduce the depth of dependent resource requests - Inline critical CSS to avoid extra network roundtrips - Use `preload` hints for essential assets found deep in the chain ## Check Identify long chains of dependent requests that block the critical rendering path using Lighthouse or WebPageTest. ## Fix Flatten the request chain by inlining critical resources or using preload hints for essential assets. ## Explain Explain how critical request chains impact the Time to First Paint and how to optimize the rendering path. ## Code Review Review the routes, assets, and loading behavior that affect Minimize critical request chains. Flag exact files, requests, or rendering steps that add unnecessary network, CPU, or layout cost, and describe the measurement method used to confirm the issue. --- For full implementation details, code examples, and framework-specific guidance, see `references/rule.md`.

How to install
mdr add thedaviddias/front-end-checklist/critical-request-chains@sha256:1971bbd9d4b87adfThe 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.
