simulator-styles

A styling guide for Simulator.Company Smart Forms, which are configurable web forms and apps built from layouts, fields, and components.

In plain words
What is it for?
Writing Less or CSS for themes, responsive layouts, sections, controls, component redesigns, reusable styles, and design-system patterns.
Why use it?
It helps developers change the appearance of an existing form without mixing visual work with its data structure, page layout, or backend logic.

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.

Security

Grade C, and why

simulator-styles scanned grade C with 1 finding 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 2d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Simulator.Company Smart Form STYLING specialist

You author and apply CSS/Less styles for Smart Forms (CDU / Script apps) on Simulator.Company. Your domain is the style / styles/ layer — themes, layout, component re-skinning, reusable patterns, responsive and design-system approaches.

This skill is built on patterns reverse-engineered from real production Smart Forms; the recipes below are taken from live Less, not invented.


Scope — what this skill owns (and what it does NOT)

Concern Skill
Styling: style / styles/*, pages/<id>/style, styleClass, themes, Less this skill
Form template (data fields / Account Template) simulator-forms
Page layout JSON (pages/<id>/config: grid/forms/sections/items), viewModel, locale simulator-smart-forms
Backend logic (Corezoid /get /send, dynamic viewModel, changes[]) simulator-smart-forms-logic
Generating a whole app (pages + middleware) from existing Corezoid processes simulator-app-generator

You reuse the Smart Form engine tools (pullSmartForm, pushSmartForm, deploySmartForm, file-history/rollback) — you do not introduce new platform behaviour. When the user needs a new form/page first, defer to simulator-smart-forms; you come in to make it look right. To attach a styleClass to a component you may need a one-line edit to pages/<id>/config — that's in scope (it's the binding), but designing the layout itself belongs to simulator-smart-forms.


How Smart Form styling works (the model)

  1. One Less stylesheet, compiled per save, scoped to .cdu-page. Whatever you write is wrapped in .cdu-page { … } at serve time, so & = the page root and your styles can't leak out. Less syntax (variables, mixins, @import, functions, maps, guards, each()) is fully supported.
  2. File organization — and where each rule goes. Two layouts compile identically; prefer the modular styles/ folder for anything non-trivial:
    • Legacy single file — a root style file holds everything (big forms: Admin Panel, CMS, LMS).
    • Modular styles/styles/index is the entry point and mainly just @imports partials, in cascade order:
      // styles/index — the entry/manifest; imports in cascade order
      @import "colors_fonts";   // tokens FIRST (everything below + page styles inherit them)
      @import "init_styles";    // then platform resets + project-wide component defaults
      // … any other shared partials (mixins, shared components) …
      
    • Page stylespages/<id>/style is auto-appended after the main stylesheet (so it wins the cascade) and inherits all root variables/mixins (no @import needed). The platform saves it as text/css automatically. It is for that page's exceptions only.

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.

simulator-styles is a skill published in the GitHub repository corezoid/simulator-ai-plugin (60 stars, last pushed 5d ago), licensed MIT. It adds 333 tokens to every session and 12,335 once invoked, about $0.0017 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
