Build Progressive Web Apps (PWAs) with offline support, installability, and caching strategies. Trigger whenever the user mentions PWA, service workers, web app manifests, Workbox, 'add to home screen', or wants their web app to work offline, feel native, or be installable.

When to use

• Use when the user wants their web app to work offline or on unreliable networks.
• Use when building a mobile-first web project where users should be able to install the app to their home screen.
• Use when the user asks about caching strategies, service workers, or improving web app performance and resilience.
• Use when the user mentions Workbox, web app manifests, background sync, or push notifications for the web.
• Use when the user asks "can my website be installed like an app?" or "how do I make my site work offline?" — even if they don't use the word PWA.

When not to use

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
