PixelPilot: Instructions file for GitHub Copilot

vscode/.github/instructions/uiux-ai-workflow.instructions.md

PixelPilot uiux-ai-workflow.instructions.md is an instructions file for GitHub Copilot from dev-lou/PixelPilot. It costs 2,762 tokens per session, scanned A, original, MIT.

A set of instructions for using AI coding assistants as partners that follow a project’s design system. A design system is the shared set of visual rules, reusable components, and naming conventions used by an interface.

In plain words
What is it for?
Use it to prepare prompts, generate frontend boilerplate, enforce design tokens, and review AI-written interface code.
Why use it?
It helps prevent generated code from introducing inconsistent spacing, colors, fonts, or UI behavior.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is dev-lou/PixelPilot's own configuration. It tells GitHub Copilot how to work on PixelPilot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything PixelPilot configures →

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-ai-workflow.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 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.

UI/UX AI Workflow 2026

AI-native engineering patterns: using AI tools (Copilot, Claude, Cursor, Lovable) as design-system-aware partners, not generic code generators. Token enforcement, boilerplate generation, prompt patterns, and review checklists.


CORE PRINCIPLE — Constrain the AI

An AI that doesn't know your design system will generate:

  • padding: 10px instead of var(--space-3)
  • color: #3B82F6 instead of var(--accent)
  • border-radius: 8px instead of var(--radius-md)
  • Inter font instead of your brand font
  • window.alert() instead of SweetAlert2

Solution: Prime every AI prompt with your system context. This skill IS that context.


STEP 1 — AI SYSTEM PROMPT (paste at start of every session)

You are a senior frontend engineer building [PROJECT NAME].

Design language: [LANGUAGE — e.g., Premium Modern]
Tech stack: [e.g., Next.js 14, Tailwind v4, TypeScript]

RULES — non-negotiable:
1. All spacing uses CSS tokens: var(--space-1) through var(--space-40). Never arbitrary px.
2. All colors use semantic tokens: var(--bg), var(--surface), var(--text), var(--accent), etc.
3. All fonts via: var(--font-display), var(--font-body), var(--font-mono).
4. Border radius via: var(--radius-sm), var(--radius-md), var(--radius-lg).
5. No window.alert/confirm/prompt — use the swal object from uiux-components.md.
6. Every component handles all 8 states (default/hover/focus/active/loading/disabled/error/success).
7. Every <img> has width, height, loading, alt.
8. No inline styles except for dynamic/computed values.
9. Mobile-first: start at 390px.
10. Dark mode via [data-theme="dark"] on <html>. Colors must work in both themes.

Token file excerpt:
[paste relevant section of tokens.css here]

STEP 2 — PROMPT PATTERNS

Generate a New Component

Create a [COMPONENT NAME] component for a [LANGUAGE] design system.

Requirements:
- Uses only var(--*) tokens for colors, spacing, radius
- Handles all 8 states: default, hover, focus, active, loading, disabled, error, success
- Mobile-first, responsive
- Accessible: correct ARIA roles, keyboard navigable
- Follows the button/card/form patterns in [uiux-interactive.md / uiux-states.md]

Output: HTML + CSS (no Tailwind). Use BEM-adjacent naming (.component__element--modifier).

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.
