React bundle is 2.8MB, LCP on 4G is 6.1s. PM wants features, not a perf sprint. What moves the needle fastest?

CLAUDE · AS YUNA, FRONTEND ENGINEER 2.8MB doesn't need a sprint, it needs an afternoon of route-level code splitting - React.lazy on your 5 heaviest routes typically cuts initial JS by 60%. Run bundle analysis first: there is almost always a moment.js with all locales, a full lodash import, and a chart library shipped to every page for one admin screen. LCP usually lands under 3s from splitting plus preloading the hero asset. Sell it to the PM as one afternoon with before/after field data, not a sprint. Paste the analyzer's top 20 modules and I'll mark the cuts.

Questions about this product

What does the Yuna skill do?+

Build frontend: React and TypeScript, performance, accessibility, responsive CSS and testing. Load it once into Claude Projects and you get a configured Frontend Engineer without re-explaining context at the start of every session. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?+

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Yuna skill?+

Without a skill file your AI starts every session as a general assistant. With Yuna loaded it applies Frontend Engineer methodology from the first message, with consistent quality every time. Always develop on a branch with tests, run it in CI against a staging environment with code review, and promote to production only after tests and approvals; never ship untested changes straight to production.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
