Use when auditing slow page loads, heavy assets, or rendering delays related to Enable browser caching. 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
# Enable browser caching Proper caching eliminates redundant downloads on repeat visits—returning users see near-instant page loads when assets are served from browser cache. ## Quick Reference - Use immutable caching for hashed assets (1 year max-age) - Use short cache + revalidation for HTML pages - ETags enable efficient cache validation - stale-while-revalidate improves perceived performance ## Check Verify that proper cache headers are set for static resources to enable browser caching. ## Fix Configure appropriate Cache-Control and ETag headers for different resource types. ## Explain Explain how browser caching reduces server requests and improves repeat visit performance. ## Code Review Review the routes, assets, and loading behavior that affect Enable browser caching. 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/browser-caching@sha256:270b8d299a2ae8abThe 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.
