WEB PERFORMANCE / Cloudflare

Cloudflare Web Performance Audit

Builds a performance review from browser traces, request details and relevant source instead of generic optimization advice.

See setup guidance ↓Original source ↗

“Audit, diagnose, or optimize website loading and interaction performance, Core Web Vitals, and Lighthouse performance scores.”

01 / THE REASONING

Why this made the selection.

  • Starts by discovering available measurement tools and records measurements it could not collect.
  • Connects individual requests and trace insights to concrete changes, while skipping recommendations with no observed impact.

02 / THE REVIEW RECORD

What we actually inspected.

Source review has boundaries.
A clear record is more useful than a “safe” badge.

Material inspected

  • skills/web-perf/SKILL.md
  • LICENSE

Our findings

  • The workflow covers trace, network and optional codebase inspection and omits codebase claims for third-party sites.
  • It asks for verification before recommending resource removal, though a single captured route has limited coverage.
  • MCP setup changes are explicitly conditional on the user’s authorized scope.

Not established by this review

  • Source inspection only; no skill installation or workflow execution was performed.

The review applies to the material and revision named here. A newer upstream release can change its behavior.

DOCUMENTED COMMAND

npx skills add https://github.com/cloudflare/skills/tree/b052c32bab7dd493513260228a36c88294f343f1/skills/web-perf

Copying does not execute this command. It may retrieve a newer version than the reviewed source.

  1. Install the complete skill directory with its references and helpers; a copied SKILL.md alone may be incomplete.
  2. Choose the intended agent and project scope in the installer, then review its permissions before using the skill.

Before you start

  • Node.js/npm for this installer
  • An agent that supports the Agent Skills format
  • A reachable target page
  • Browser tracing capability for measured metrics
