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.

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 | $0.00034 | $0.00531 |
| Opus 5 | $0.00017 | $0.00266 |
| Sonnet 5 | $0.00007 | $0.00106 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
react-component-architecture 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.

React Component Architecture
Table of Contents
Overview
Build scalable, maintainable React components using modern patterns including functional components, hooks, composition, and TypeScript for type safety.
When to Use
- Component library design
- Large-scale React applications
- Reusable UI patterns
- Custom hooks development
- Performance optimization
Quick Start
Minimal working example:
// Button.tsx
import React, { useState, useCallback } from 'react';
interface ButtonProps {
variant?: 'primary' | 'secondary' | 'danger';
size?: 'sm' | 'md' | 'lg';
disabled?: boolean;
onClick?: () => void;
children: React.ReactNode;
}
export const Button: React.FC<ButtonProps> = ({
variant = 'primary',
size = 'md',
disabled = false,
onClick,
children
}) => {
const variantStyles = {
primary: 'bg-blue-500 hover:bg-blue-600',
secondary: 'bg-gray-500 hover:bg-gray-600',
danger: 'bg-red-500 hover:bg-red-600'
};
const sizeStyles = {
// ... (see reference guides for full implementation)

Best Practices
✅ DO
- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying
❌ DON'T
What ships with it
6 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.

react-component-architecture is a skill published in the GitHub repository aj-geddes/useful-ai-prompts (336 stars, last pushed 6mo ago), licensed MIT. It adds 34 tokens to every session and 531 once invoked, about $0.0002 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 2026-09-03.
