Agent Skill

用于辅助安全审计、权限检查、凭据风险、认证流程和常见漏洞排查。它适合让 Agent 梳理敏感配置、检查依赖风险、分析鉴权逻辑或生成安全复核清单。使用时不能把工具输出直接当最终结论，涉及密钥、令牌、用户数据或生产系统时，应先确认最小权限、脱敏方式和操作边界。

简介

全面的核心网络生命周期审计，提供根本原因诊断和资源优化指导。

涵盖五个关键指标（LCP、CLS、INP、FCP、TTFB）以及诊断树，可查明特定原因，例如服务器速度慢、图像尺寸缺失、字体加载问题和主线程阻塞
包括根据行业基准细分 HTML、CSS、JavaScript、图像、字体和第三方脚本大小的结构化资源分析
提供按影响排序的优先修复建议，以及只需最少努力的快速获胜优化
专为跨不同技术堆栈的页面速度调查、Lighthouse 分数改进和性能瓶颈识别而设计

Audit Speed

Deep Core Web Vitals audit with root-cause analysis trees and resource optimization recommendations.

Core Web Vitals Thresholds

Metric	Good	Needs Improvement	Poor
LCP (Largest Contentful Paint)	< 2.5s	2.5s - 4.0s	> 4.0s
CLS (Cumulative Layout Shift)	< 0.1	0.1 - 0.25	> 0.25
INP (Interaction to Next Paint)	< 200ms	200ms - 500ms	> 500ms
FCP (First Contentful Paint)	< 1.8s	1.8s - 3.0s	> 3.0s
TTFB (Time to First Byte)	< 800ms	800ms - 1800ms	> 1800ms

Before You Start

Gather this context:

Which pages? Homepage, key landing pages, or specific slow pages.
Current scores. If the user has Lighthouse or PageSpeed Insights data, start there.
Tech stack. CMS, framework, hosting — this determines which optimizations are available.
Known constraints. Third-party scripts they can't remove, design requirements that limit optimization.

If no data is available, suggest running Google PageSpeed Insights on the key URLs.

LCP Root-Cause Tree

LCP measures when the largest visible element finishes rendering. Diagnose:

Is TTFB slow (> 800ms)?

→ Server response time issue
Check: hosting quality, CDN configuration, database queries, server-side rendering time
Fix: upgrade hosting, add CDN, optimize server-side code, enable caching

Is the LCP element an image?

→ Image optimization issue
Check: image format (use WebP/AVIF), image size (serve responsive sizes), lazy loading on LCP image (should NOT be lazy loaded)
Fix: convert to modern formats, add width/height attributes, use fetchpriority="high" on LCP image, preload the LCP image

Is the LCP element text?

→ Font loading issue
Check: custom fonts blocking render, font file size, font-display strategy
Fix: use font-display: swap or optional, preload critical fonts, subset fonts to used characters

Is render-blocking CSS/JS delaying the LCP?

Check: large CSS files in <head>, synchronous JS before content
Fix: inline critical CSS, defer non-critical CSS, async/defer JS

CLS Root-Cause Tree

CLS measures unexpected layout shifts. Diagnose:

Do images/videos lack dimensions?

→ Browser can't reserve space before loading
Fix: add width and height attributes to all <img> and <video> elements, use CSS aspect-ratio

Do ads or embeds inject content?

→ Dynamic content pushing existing content down
Fix: reserve space for ad slots with min-height, use contain-intrinsic-size for lazy content

Do fonts cause text reflow?

→ FOUT (Flash of Unstyled Text) causes layout shift when custom font loads
Fix: use font-display: optional (no swap = no shift), or match fallback font metrics

Does dynamic content insert above the fold?

→ Banners, cookie notices, notifications pushing content
Fix: use overlays instead of inline insertions, or reserve space with fixed-height containers

INP Root-Cause Tree

INP measures responsiveness to user interactions. Diagnose:

Is the main thread blocked by long tasks?

Check: JavaScript execution time, third-party scripts, large DOM
Fix: break long tasks with requestIdleCallback or setTimeout, code-split heavy modules

Do event handlers do heavy synchronous work?

Check: click handlers that trigger large DOM updates, form validation on every keystroke
Fix: debounce inputs, use requestAnimationFrame for visual updates, offload work to web workers

Are third-party scripts competing for the main thread?

Check: analytics, chat widgets, A/B testing tools, social embeds
Fix: defer loading until after interaction, use loading="lazy" for embeds, consider removing low-value scripts

Resource Analysis

Break down the total page weight:

Resource Type	Size	Assessment	Action
HTML	[x] KB	[ok/large]	Compress, reduce inline styles/scripts
CSS	[x] KB	[ok/large]	Remove unused CSS, minify, critical CSS extraction
JavaScript	[x] KB	[ok/large]	Code-split, tree-shake, defer non-critical
Images	[x] KB	[ok/large]	Modern formats, responsive sizes, lazy load below fold
Fonts	[x] KB	[ok/large]	Subset, limit families/weights, preload critical
Third-party	[x] KB	[ok/large]	Audit necessity, defer, self-host if possible

Benchmarks:

Total page weight under 1.5 MB is good
JavaScript under 300 KB (compressed) for most sites
CSS under 100 KB (compressed)
First-party fonts under 100 KB

Output Format

Speed Audit: [URL or domain]

Core Web Vitals

Metric	Value	Rating	Root Cause
LCP	[value]	Good / Needs Improvement / Poor	[identified cause]
CLS	[value]	...	...
INP	[value]	...	...
FCP	[value]	...	...
TTFB	[value]	...	...

Resource Breakdown [Table from Resource Analysis]

Priority Fixes

For each failing metric, ordered by impact:

[Metric]: [Root cause]

- Current: [value] - Target: [threshold] - Fix: [specific action] - Estimated impact: [high/medium/low]

Quick Wins List optimizations that require minimal effort:

Add width/height to images
Set fetchpriority="high" on LCP image
Defer non-critical JavaScript
...

Pro Tip: Use the free CWV Impact Calculator to estimate the traffic impact of fixing Core Web Vitals, and the Critical CSS Generator to extract above-the-fold CSS. SEOJuice MCP users can run /seojuice:page-audit [domain] [url] for instant CWV scores, Lighthouse data, and resource breakdowns.
