component-standards

A set of rules for building frontend UI components, the reusable pieces of an application's interface.

In plain words
What is it for?
Use it to set naming and folder conventions, define typed properties, isolate styles, avoid rendering side effects, and structure component libraries.
Why use it?
It keeps components organized, focused, consistently styled, and easier to reuse across React, Vue, and Svelte projects.

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.

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 A, and why

component-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 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.

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.

What it actually says


name: ComponentStandards type: Auto Attached description: Enforce structure, naming, and styling rules for UI components across frameworks glob: **/*.{jsx,tsx,vue,svelte} priority: high

Component Development Standards

Follow these conventions for all components.

Naming and Organization

  • Use PascalCase for component names.
  • Keep each component in its own folder with index export.
  • Group related style files alongside the component.

Reusability Principles

  • Keep components small and focused on a single responsibility.
  • Accept props with explicit types and default values.
  • Avoid side effects in rendering logic.

Styling Guidelines

  • Prefer CSS-in-JS or scoped styles to avoid global leakage.
  • Keep class names predictable and use BEM when applicable.
  • Co-locate styles with components.

Example

// Example React functional component
export interface ButtonProps {
  label: string;
  onClick?: () => void;
}

export function Button({ label, onClick }: ButtonProps) {
  return (
    <button className="btn" onClick={onClick}>
      {label}
    </button>
  );
}

This template ensures consistency and reusability across your component library.

Changes

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.

component-standards is a cursor rule published in the GitHub repository jakerains/CitrusRules (2 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 288 tokens. 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.
