Screenshot of the PerfReviews Insights dashboard analyzing joanleon.dev with the “LCP” (Largest Contentful Paint) metric selected. The LCP value is 0.88 seconds, marked Good. The interface identifies the LCP element as a text paragraph with selector .astro-j7pv25f6 and size 40,592 px². The sidebar shows other performance checks including TTFB, images, videos, page weight, and external scripts.
Screenshot of the PerfReviews Insights dashboard analyzing the website joanleon.dev on a mobile viewport (390×844, iPhone 14). The “TTFB” (Time to First Byte) metric is selected in the sidebar. The result shows a TTFB of 203 ms, labeled Good. A connection breakdown chart shows DNS lookup (15 ms, 4%), TCP connect (161 ms, 45%), TLS handshake (158 ms, 44%), and server request (25 ms, 7%). The page includes explanations of the TTFB metric and links to optimization resources.

Table titled “Results” showing reductions in JavaScript bundle sizes for web performance features. Columns: Skill, Before, After, and Reduction. • webperf-loading: 24,199 B → 11,149 B (−54%) • webperf-core-web-vitals: 13,890 B → 10,266 B (−26%) • webperf-interaction: 17,143 B → 12,443 B (−27%) • webperf-media: 13,273 B → 12,017 B (−9%) • webperf-resources: 11,700 B → 11,026 B (−6%) • Total L2: 82,916 B → 59,612 B (−28%) The table highlights overall bundle size reduction after optimization.
When a Skill activates, its SKILL.md loads into context. The webperf-loading was 24 KB, most of it unnecessary to decide which script to run
I applied progressive disclosure and brought it down to 11 KB

Stylized screenshot of a dark code editor window titled “WebPerf Snippets agent-first: structured returns and minimal tokens.” It contrasts two approaches: • Before: an agent parsing a console string like “🟢 LCP: 1.24s (good)”. • After: a structured JSON-like object containing performance data for the Largest Contentful Paint (LCP) metric, including fields such as script: "LCP", status: "ok", metric: "LCP", value: 1240, unit: "ms", rating: "good", thresholds for good and needs improvement, and details about the measured element (img.hero, hero.avif, sizePixels: 756000). The graphic illustrates the shift from parsing human-readable console output to returning structured performance data for agents.
WebPerf Snippets agent-first
WebPerf Snippets SKILLs were written for humans: emojis, colours, tables.
The agent had to parse all of that.
I added structured JSON returns and a build with terser that removes the console code. 80 lines → ~300 characters.

A slow UX affects people’s perception of three important brand elements that are completely unrelated to page speed: content, design, and usability.
Here's why that takeaway is relevant in an increasingly competition online landscape 👉 www.speedcurve.com/blog/brand-p...

• Workflows with decision trees: if TTFB > 600ms → run Sub-Parts.js

WebPerf Snippets and Agent SKILLs: deterministic audits with Chrome DevTools MCP
Claude Code report showing Usercentrics scripts causing performance issues by combining 'preload' and 'async'. It recommends removing preloads or using fetchpriority='low' to avoid competing with critical LCP resources.
I've been using WebPerf Snippets in my audits for years.
Scripts to measure LCP, INP, CLS, TTFB, Render Blocking...
The next step: turning them into tools an AI agent can use autonomously.
But there's a design decision that makes all the difference.
