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
# Front-end performance optimization ## Purpose Use measurable methods to locate front-end performance bottlenecks, and converge optimization suggestions to the user's main path, build products, and runtime evidence. ## Procedure 1. Lock in experience goals - Clarify whether the problem is first screen loading, interaction delay, scrolling lag, memory increase, network waterfall, packet size, or visual stability. - Document routes, devices, network conditions, browsers, replication steps, and currently available metrics. - When there are no indicators, establish a baseline first and do not directly give generalized suggestions of "optimizing everything". 2. Establish a measurement baseline - Read project scripts, build configurations, dependencies and existing performance reports. - Prioritize the use of Lighthouse, Performance trace, React Profiler, Vue Devtools, Memory snapshot or RUM data for page experience. - Prioritize build products, source maps, dependency duplication, first-screen chunks and dynamic import boundaries for package bodies. …

How to install
mdr add bovinphang/frontend-craft/fec-performance-optimization@sha256:42846bce615c7a21The line at the top of this page pins the label git:20260611.9d7f5e4, 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.
