    Core Web Vitals Fixer for WordPress

    Example session with this skill installed

    Mobile PageSpeed for our Astra + Elementor site is 58: LCP 4.6 s, CLS 0.21, INP 170 ms. The homepage has an Elementor hero slider with a 1.8 MB JPEG, Google Fonts from the CDN, GA4 in wp_head with no consent banner, and a newsletter bar that appears at the top after load.

    • Read your context and instructions
    • Compiled the core web vitals

    Mode: DIAGNOSE. LCP and CLS fail; INP passes.

    Root causes

    • LCP: 1.8 MB JPEG hero in a slider, likely not preloaded (Gate 2-A, 2-B).
    • LCP: Google Fonts from CDN, render-blocking (Gate 2-C).
    • LCP: GA4 loaded eagerly, competing for bandwidth (Gate 3-B).
    • CLS: newsletter bar injected at top after load (Gate 4-B).

    About this skill

    High-Performance Core Web Vitals Optimization

    This skill is a specialized diagnostic and remediation tool for WordPress developers facing failing Core Web Vitals (CWV). Unlike generic performance advice, it traces LCP, INP, and CLS issues directly to the WordPress/PHP/Browser stack using production-tested engineering patterns.

    What it does

    • DIAGNOSE: Analyzes PageSpeed Insights, CrUX data, or Lighthouse reports to generate a ranked root-cause list.
    • FIX: Delivers prioritized, runnable code patches for common WordPress bottlenecks like hero image discovery, render-blocking scripts, and layout shifts.
    • Consent-Aware Tuning: Implements advanced patterns for Consent Mode v2 and deferred analytics loading—solving the hidden LCP/INP drag caused by gtag.js.

    Why it's better than manual prompting

    Generalized AI models often suggest counter-productive fixes, like lazy-loading hero images or generic minification. This skill uses a strict 8-gate framework to prevent anti-patterns, calculates a ROI-driven "Action Score" (Impact²/Effort), and provides an objective 12-point acceptance checklist for verification.

    Supported Environment

    • WordPress (Classic & Block/FSE themes)
    • Common page builders (Elementor, Divi, Bricks)
    • Google Tag Manager and Analytics (GA4)
    • Consent Management Platforms (CMP)

    • Does not fix server-side TTFB issues or slow SQL queries.
    • Cannot resolve lab/field data conflicts without recent code changes.
    • Requires manual integration for custom-built themes.
