high-perf-browser SKILL.md skillB
This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.
high-perf-browser from wondelai/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wondelai/skills/high-perf-browser@v1.4.1Pins v1.4.1 in mdr.lock. Pin the fingerprint instead.

Optimize web performance through network protocols, resource loading, and browser rendering internals. Use when the user mentions "my site is slow", "Core Web Vitals", "HTTP/2 or HTTP/3", "resource hints", "network latency", "render blocking", "TCP/TLS optimization", "service worker", "Cache-Control or caching strategy", or "critical rendering path". Also trigger when diagnosing slow page loads, optimizing time to first byte, choosing between WebSocket and SSE, or reducing bundle sizes. For UI…
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
# High Performance Browser Networking Framework A systematic approach to web performance grounded in how browsers, protocols, and networks actually work. Apply these principles when building frontend applications, setting performance budgets, configuring servers, or diagnosing slow page loads. ## Core Principle **Latency, not bandwidth, is the bottleneck.** Most web performance problems stem from too many round trips, not too little throughput. A 5x bandwidth increase yields diminishing returns; a 5x latency reduction transforms the user experience. **The foundation:** Every request passes through DNS resolution, TCP handshake, TLS negotiation, and HTTP exchange before a single byte of content arrives — each step adding round-trip latency. High-performance applications minimize round trips, parallelize requests, and eliminate unnecessary network hops. Understanding the protocol stack is the prerequisite for meaningful optimization. ## Scoring …

How to install
mdr add wondelai/skills/high-perf-browser@sha256:fed643149198165eThe line at the top of this page pins the label v1.4.1, 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.
