How does it test offline functionality?

The skill emulates a network disconnection via Playwright/CDP, attempts to reload the page, and captures a screenshot to verify if a custom offline fallback or cached content is displayed.

Can I use this skill to test PWAs running on localhost?

Yes, the audit recognizes localhost and 127.0.0.1 as secure contexts, allowing you to test PWA features during the development phase.

What is the benefit of using this over standard browser tools?

This skill integrates directly into your Claude Code workflow, providing an automated, repeatable scorecard and the ability to programmatically diagnose complex service worker issues.

Do I need a specific browser to run this audit?

Yes, a Chromium-based browser is required because the skill utilizes Chrome DevTools Protocol (CDP) for deep service worker inspection and network emulation.

What parameters does the PWA Audit skill validate?

It checks for HTTPS enforcement, web app manifest presence and integrity, service worker status, offline page loading, and installability requirements like icons and display modes.

Mobile Development

Conducts comprehensive Progressive Web App readiness assessments to validate manifests, service workers, and offline capabilities.

The PWA Audit skill provides a deep technical evaluation of web applications to ensure they meet Progressive Web App standards. It automates the validation of web app manifests, inspects service worker lifecycles and scopes via Chrome DevTools Protocol (CDP), and performs live offline capability tests by emulating network disconnections. This tool is essential for developers looking to verify installability criteria, diagnose 'Add to Home Screen' issues, and ensure robust offline fallback behavior before deploying to production or app stores.
