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.

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 | $0.00056 | $0.01078 |
| Opus 5 | $0.00028 | $0.00539 |
| Sonnet 5 | $0.00011 | $0.00216 |
| Haiku 4.5 | $0.00006 | $0.00108 |
Grade C, and why
heroui-migration 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 11d 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 v2 to v3 Migration Guide
This skill helps agents migrate HeroUI v2 applications to v3. HeroUI v3 introduces breaking changes: compound components, no Provider, Tailwind v4, and removed hooks.
Installation
curl -fsSL https://heroui.com/install | bash -s heroui-migration
CRITICAL: Always Fetch Migration Docs Before Applying
Do NOT assume v2 patterns work in v3. Always fetch migration guides before implementing changes.
Key v2 → v3 Changes
| Feature | v2 (Migrate From) | v3 (Migrate To) |
|---|---|---|
| Provider | <HeroUIProvider> required |
No Provider needed |
| Component API | Flat props: <Card title="x"> |
Compound: <Card><Card.Header> |
| Event handlers | onClick |
onPress |
| Styling | classNames prop |
className prop |
| Hooks | useSwitch, useDisclosure, etc. |
Compound components, useOverlayState |
| Packages | @heroui/system, @heroui/theme |
@heroui/react, @heroui/styles |
Accessing Migration Documentation
For migration details, examples, and step-by-step guides, always fetch documentation:
Using Scripts
# List all available component migration guides
node scripts/list_migration_guides.mjs
# Get main migration workflow (full or incremental)
node scripts/get_migration_guide.mjs full
node scripts/get_migration_guide.mjs incremental
# Get component-specific migration guides
node scripts/get_component_migration_guides.mjs button
node scripts/get_component_migration_guides.mjs button card modal
# Get styling migration guide
node scripts/get_styling_migration_guide.mjs
# Get hooks migration guide
node scripts/get_hooks_migration_guide.mjs
Direct URLs
Migration docs (preview): use a concrete guide URL from the examples below, and never fetch a URL that still contains a placeholder.
What ships with it
6 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-migration is a skill published in the GitHub repository heroui-inc/heroui (30,626 stars, last pushed yesterday), licensed Apache-2.0. It adds 56 tokens to every session and 1,078 once invoked, about $0.0003 per session on Opus 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.
