Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionpwa-developmentExecute the skills CLI command in your project's root directory to begin installation:
Fetches pwa-development from jwynia/agent-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate pwa-development. Access via /pwa-development in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

PWAs fail when offline behavior is an afterthought. A PWA is not "add service worker to existing app." It's a fundamental architectural decision about data flow, caching, and connectivity failure.
Symptoms: No manifest.json, no service worker, online-only
Interventions:
scripts/manifest-generator.ts to create manifest<link rel="manifest"> to HTML headscripts/sw-scaffolder.tsSymptoms: Manifest exists but SW missing, breaks offline
Key Questions:
Interventions:
scripts/cache-strategy-advisor.tsSymptoms: Stale content, unexpected caching behavior
Interventions:
scripts/pwa-audit.tsdata/caching-strategies.jsonSymptoms: Users stuck on old versions, multiple refreshes needed
Interventions:
assets/update-prompt.tsx)Symptoms: User actions lost offline, no sync indicator
Interventions:
Symptoms: Works on Android, breaks on iOS
Interventions:
data/ios-quirks.jsonIndicators: Lighthouse PWA 100, works offline, updates cleanly
| Strategy | Use For | Behavior |
|---|---|---|
| Cache First | Static assets, fonts | Serve from cache, update in background |
| Network First | API data, user content | Try network, fall back to cache |
| Stale While Revalidate | Semi-static content | Serve stale, update cache for next time |
| Network Only | Auth, real-time data | Always network, no caching |
| Script | Purpose |
|---|---|
manifest-generator.ts |
Generate manifest.json |
sw-scaffolder.ts |
Generate service worker |
cache-strategy-advisor.ts |
Recommend caching strategies |
pwa-audit.ts |
Validate PWA configuration |
Precaching every asset - massive initial download. Fix: Precache only critical app shell. Runtime cache content.
Never expiring caches - stale content forever. Fix: Cache versioning, delete old on activate, set max age.
Forcing updates without notification. Fix: Notify user, let them choose when to refresh.
Building for Chrome, testing iOS last. Fix: Test iOS early. Accept iOS limitations.

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

We added pwa-development from the explainx registry; install was straightforward and the SKILL.md answered most questions upfront.
pwa-development reduced setup friction for our internal harness; good balance of opinion and flexibility.
Registry listing for pwa-development matched our evaluation — installs cleanly and behaves as described in the markdown.
I recommend pwa-development for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.

Useful defaults in pwa-development — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
