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 →
- high Prompt Injection · line 123 Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.
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 | $0.00061 | $0.03761 |
| Opus 5 | $0.00030 | $0.01880 |
| Sonnet 5 | $0.00012 | $0.00752 |
| Haiku 4.5 | $0.00006 | $0.00376 |
Grade A, and why
maquina-ui-standards 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 9d 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.

Maquina UI Standards
Build production-quality Rails UIs with maquina_components — ERB partials styled with Tailwind CSS 4 and data attributes, inspired by shadcn/ui.
When to Use This Skill
- Implementing UI for a feature spec
- Creating new views or pages
- Building forms with validation
- Designing page layouts
- Reviewing UI implementation for consistency
Quick Reference
Component Rendering
<%# Partial components %>
<%= render "components/card" do %>
<%= render "components/card/header" do %>
<%= render "components/card/title", text: "Title" %>
<% end %>
<% end %>
<%# Data-attribute components (forms) %>
<%= f.text_field :email, data: { component: "input" } %>
<%= f.submit "Save", data: { component: "button", variant: "primary" } %>
Decision Framework
| Need | Component | Why |
|---|---|---|
| Container with header/content/footer | Card | Structured content grouping |
| Important message to user | Alert | Draws attention, semantic variants |
| Status indicator | Badge | Compact, inline status |
| Data display | Table | Structured rows/columns |
| No data state | Empty | Consistent empty patterns |
| User actions menu | Dropdown Menu | Accessible, keyboard-navigable |
| Selection from options | Toggle Group | Visual, single/multi select |
| Selection from many options | Combobox | Searchable, filterable |
| Date selection (inline) | Calendar | Always-visible date picker |
| Date selection (popover) | Date Picker | Compact form date input |
| Page location | Breadcrumbs | Navigation context |
| Large result sets | Pagination | Pagy integration |
| App navigation | Sidebar | Collapsible, persistent state |
| Temporary notifications | Toast | Non-intrusive feedback |
| Form inputs | Form components | Consistent styling via data attrs |
File References
| File | Content |
|---|---|
| component-catalog.md | All components with props, variants, examples |
| layout-patterns.md | Page structure, grids, responsive design |
| form-patterns.md | Forms, validation, field groups |
| turbo-integration.md | Frames, Streams, Morph with components |
| spec-checklist.md | UI implementation checklist for specs |
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.
