PixelPilot uiux-components.instructions.md

A collection of reusable web interface components and design patterns for alerts, navigation, grids, spacing, responsive layouts, and dark or light themes.

In plain words
What is it for?
Use it when building web pages that need reusable components, responsive navigation and grids, global CSS setup, or a theme switcher that remembers the visitor’s choice.
Why use it?
It gives you consistent interface rules and ready-to-adapt examples, so you do not have to design common UI behavior from scratch.

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

PixelPilot uiux-components.instructions.md 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 515 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UI/UX Components, Alerts, Nav & Grid

Dark mode setup, global CSS reset, CDN stack, SweetAlert2 themes, spacing, responsive navigation, grid layouts.

STEP 3 — Dark/Light Mode System

Anti-FOWT (Flash of Wrong Theme) — ALWAYS inline in <head>

<script>
(function(){
  var t=localStorage.getItem('theme')||
    (window.matchMedia('(prefers-color-scheme: dark)').matches?'dark':'light');
  document.documentElement.setAttribute('data-theme',t);
})();
</script>

Toggle JS (universal, all stacks)

const applyTheme = t => {
  document.documentElement.setAttribute('data-theme', t);
  localStorage.setItem('theme', t);
};
const toggleTheme = () => {
  applyTheme(document.documentElement.getAttribute('data-theme') === 'dark' ? 'light' : 'dark');
};
// Init
applyTheme(localStorage.getItem('theme') || (matchMedia('(prefers-color-scheme: dark)').matches ? 'dark' : 'light'));
// System change listener
matchMedia('(prefers-color-scheme: dark)').addEventListener('change', e => {
  if (!localStorage.getItem('theme')) applyTheme(e.matches ? 'dark' : 'light');
});

React / Next.js Theme Hook

// hooks/useTheme.js — import in _app.js / layout.jsx
import { useEffect, useState } from 'react';
export function useTheme() {
  const [theme, setTheme] = useState('light');
  useEffect(() => {
    const saved = localStorage.getItem('theme') ||
      (matchMedia('(prefers-color-scheme: dark)').matches ? 'dark' : 'light');
    setTheme(saved);
    document.documentElement.setAttribute('data-theme', saved);
  }, []);
  const toggle = () => {
    const next = theme === 'dark' ? 'light' : 'dark';
    setTheme(next);
    document.documentElement.setAttribute('data-theme', next);
    localStorage.setItem('theme', next);
  };
  return { theme, toggle };
}

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.
