HeroUI is a React component library that provides ready-made interface elements for building web applications. Developers use its components as building blocks in React projects. The catalogue includes agents, skills, and instructions for working with HeroUI.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

SkillSpector: 1 finding, up to high
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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.01631 |
| Opus 5.5 | $0.00033 | $0.00652 |
| Sonnet 5.5 | $0.00017 | $0.00326 |
| Haiku 4.5 | $0.00008 | $0.00163 |
Grade C, and why
heroui-react scanned grade C with 2 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 1mo 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.

HeroUI v3 React Development Guide
HeroUI v3 is a component library built on Tailwind CSS v4 and React Aria Components, providing accessible, customizable UI components for React applications.
Installation
curl -fsSL https://heroui.com/install | bash -s heroui-react
CRITICAL: v3 Only - Ignore v2 Knowledge
This guide is for HeroUI v3 ONLY. Do NOT apply v2 patterns — the provider, styling, and component API all changed:
| Feature | v2 (DO NOT USE) | v3 (USE THIS) |
|---|---|---|
| Provider | <HeroUIProvider> required |
No Provider needed |
| Animations | framer-motion package |
CSS-based, no extra deps |
| Component API | Flat props: <Card title="x"> |
Compound: <Card><Card.Header> |
| Styling | Tailwind v3 + @heroui/theme |
Tailwind v4 + @heroui/styles |
| Packages | @heroui/system, @heroui/theme |
@heroui/react, @heroui/styles |
// DO NOT DO THIS - v2 pattern
import { HeroUIProvider } from "@heroui/react";
import { motion } from "framer-motion";
<HeroUIProvider>
<Card title="Product" description="A great product" />
</HeroUIProvider>;
CORRECT (v3 patterns)
// DO THIS - v3 pattern (no provider, compound components)
import { Card } from "@heroui/react";
<Card>
<Card.Header>
<Card.Title>Product</Card.Title>
<Card.Description>A great product</Card.Description>
</Card.Header>
</Card>;
Always fetch v3 docs before implementing.
Core Principles
- Semantic variants (
primary,secondary,tertiary) over visual descriptions - Composition over configuration (compound components)
- CSS variable-based theming with
oklchcolor space - BEM naming convention for predictable styling
Accessing Documentation & Component Information
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

heroui-react is a skill published in the GitHub repository heroui-inc/heroui (30,945 stars, last pushed yesterday), licensed Apache-2.0. It adds 83 tokens to every session and 1,631 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
svar-react
Use when building, configuring, styling, or modifying any SVAR React UI component from the @svar-ui/react- packages - widgets, layouts, menus, toolbars, calendars, popups, themes, and locales.
next-cache-components-adoption
Turn on Cache Components in a Next.js app and resolve the blocking routes it surfaces. Use when the user wants to enable, adopt, or migrate to Cache Components, flip the cacheComponents flag, work through a flood of blocking-prerender / instant validation errors, run the cache-components-instant-false codemod, or…
next-cache-components-optimizer
Optimize the meaningful UI available immediately from a Next.js route on an initial load (hard navigation) or named client-side navigation (soft navigation). Encode the goal as a failing @next/playwright instant() e2e and work it to green, one verified route and entry point at a time; the shipped test then guards…
next-partial-prefetching-adoption
Turn on Partial Prefetching in a Next.js app and work through the insights it surfaces. Use when the user wants to enable or adopt Partial Prefetching, flip the partialPrefetching flag, opt routes in with export const prefetch = 'partial', audit Link prefetch={true} behavior, preserve existing prefetched UI with…
next-dev-loop
Verify Next.js runtime behavior after editing app code. Use this skill to confirm a change actually works in a running app — not just that it compiles or type-checks. Combines /next/mcp (Next.js's view) with agent-browser (the browser's view). Requires a running next dev.
compiler-orchestrator
Orchestrate the Rust compiler port end-to-end. Discovers the current frontier, fixes failing passes, ports new passes, reviews, and commits in a loop.
