A guide to writing HTML and CSS for Rock RMS, a platform for managing websites and online communities. It covers Rock’s built-in page components, layouts, and styling classes.

Creating or reviewing Rock admin screens, public pages, page zones, themes, forms, panels, tables, navigation, and responsive layouts.

It helps avoid markup and styling that does not match Rock RMS’s supported patterns.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00191	$0.01367
Opus 5.5	$0.00076	$0.00547
Sonnet 5.5	$0.00038	$0.00273
Haiku 4.5	$0.00019	$0.00137

Security

Grade A, and why

rock-ui 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 2mo 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.

Rock UI Markup Skill

This skill helps you produce correct, idiomatic HTML markup for Rock RMS using its built-in components, layout system, and utility classes.

How to Navigate This Skill

Each directory has an INDEX.md to help you find what you need. Start there before writing any markup.

components/INDEX.md — Structured UI patterns: panels, cards, buttons, alerts, badges, labels, tables, navs, and more
typography/INDEX.md — Headings, font sizes, weights, alignment, color, inline elements, wrapping, line height, and font variants
layout/INDEX.md — Layout classes: Bootstrap column grid, CSS Grid utilities, flexbox, display, sizing, position, z-index
utilities/INDEX.md — Visual styling utilities: spacing, color, borders, shadows, opacity, cursors, and more
css-styling/INDEX.md — CSS custom properties (variables) for color, spacing, radius, typography, and chart/analytics color scales
patterns/INDEX.md — Assembled patterns: complete forms with field anatomy, layout, and rendered control HTML
ambiguous-usage.md — Decision guide for choosing between similar components (label vs. badge, panel vs. card, alert vs. empty state, etc.)

When you are unsure which component or class to use, read ambiguous-usage.md first.

Deployment Context

All markup produced by this skill is assumed to run inside a live Rock RMS instance. This means:

Do not include supporting infrastructure. Rock's stylesheet, Bootstrap, Tabler Icons, jQuery, and all core scripts are already loaded by the page. Never add <link> or <script> tags for these.
Do not scaffold a full HTML document. Produce only the fragment that belongs in the block or page zone — no <!DOCTYPE>, <html>, <head>, or <body> tags unless the user explicitly asks for a standalone file.
Rock's theme is already active. All CSS variables, component styles, and utility classes are available without any additional setup.

CSS Philosophy

The default output of this skill is zero custom CSS. Rock's component library, utility classes, and CSS variables cover the vast majority of UI needs. Custom CSS adds maintenance burden, can conflict with theme overrides, and breaks the design contract between markup and theme.

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.
