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.

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 | $0.00081 | $0.00895 |
| Opus 5 | $0.00041 | $0.00447 |
| Sonnet 5 | $0.00016 | $0.00179 |
| Haiku 4.5 | $0.00008 | $0.00089 |
Grade A, and why
ui-components 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 7d 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.

UI Components
Overview
Implement production UI with composition over configuration, clear state handling, and components under 200 lines.
When to Use
- Building or modifying components, pages, layouts
- Wiring interactive UI with
/ui - Refactoring overgrown or prop-heavy components
Workflow
-
Structure
- Prefer composition over configuration
- Separate data fetching from presentation
- Colocate component + test + styles when practical
- Keep files under 200 lines (split if larger)
-
State (see also
references/architecture.md)- Local (
useState) → component UI - Lifted → 2–3 siblings
- Context → theme, auth, locale
- URL → filters, pagination
- Server state (React Query/SWR) → remote data
- Avoid prop drilling deeper than 3 levels
- Local (

Required UI states
- Loading
- Error
- Empty
- Default / success
-
Responsive — MUST load
responsive-uifor layout UI- Mobile-first; verify 320 / 768 / 1024 / 1440
- No fixed widths that break small screens; adapt tables/nav
-
Icons (default on — do not omit)
- MUST use Reicon for nav, toolbars, empty states, and icon buttons unless the project already standardizes another library
- Vanilla HTML/CSS/JS: add CDN
https://unpkg.com/reicon/cdn/reicon.min.js+<re-icon icon="kebab-name" size="20"> - React:
reicon-react; Vue/Svelte: matching package — seereferences/reicon-icons.md - Prefer
currentColor+ token text classes; Outline default, Filled for emphasis - Icon-only controls need an accessible name
- Text-only UI only with an explicit waiver in the Conventions check
-
Selects / filters (product UI)
- Prefer custom select / combobox / listbox styled with tokens — not bare OS
<select>chrome for dashboard filters and toolbars - Trigger: label + value + caret; generous end padding / gap so the chevron is not flush to the right edge
- Menu: token surface, hover/selected states, Escape + outside-click close; keyboard path required
- Native
<select>only with waiver (e.g. native mobile OS picker required) — note in Conventions
- Prefer custom select / combobox / listbox styled with tokens — not bare OS
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.

ui-components is a skill published in the GitHub repository sukirman1901/frontend-expert (10 stars, last pushed 4d ago), licensed MIT. It adds 81 tokens to every session and 895 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
