A guide to building web interfaces with React, Next.js, Vue, Nuxt, Angular, Svelte, and related tools. It covers interface structure, server rendering, browser rendering, state, data fetching, and release preparation.

In plain words
What is it for?
Use it to build web pages and applications, fix server-rendering or hydration problems, set up frontend architecture, manage state and data fetching, and improve frontend performance.
Why use it?
It helps diagnose screens that render differently between the server and browser, and gives a clear structure for managing interface state and data. It also helps teams choose a suitable web framework and setup.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

software-frontend scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Frontend Engineering

Use this skill for production web frontend work across React, Next.js, Vue, Nuxt, Angular, Svelte, and adjacent tooling. It owns framework choice, frontend implementation patterns, hydration and SSR debugging, state and data-fetching patterns, and frontend release discipline.
