# Impeccable

> Design vocabulary, rules, and skills for AI coding agents.

Impeccable is an open-source design skill and vocabulary framework built for AI coding agents like Claude Code, Cursor, and Copilot. It gives agents structured design systems, rules, and commands to detect generic AI design patterns, refine UI components, and maintain consistent styling. It also includes an in-browser live mode that lets you pick elements and steer agent modifications directly on localhost.

## What it is for

- Detect and eliminate common AI design tropes like generic beige palettes and nested card layouts
- Extract and maintain a portable DESIGN.md specification across development sessions
- Steer frontend design refinements directly in the browser on localhost with visual overlays
- Refactor typography, layout hierarchy, and component spacing using agent slash commands

## Features

- Comprehensive slop detector with 61 visual and layout heuristic checks
- Portable DESIGN.md generation to store and enforce design tokens and rules
- Specialized agent commands including typeset, layout, colorize, polish, distill, and clarify
- Live Mode visual helper injected into localhost for interactive element picking and steering
- Compatible with Claude Code, Cursor, GitHub Copilot, Codex CLI, and Gemini CLI

## Why it was saved

- [@adam_ha_yes, 19 August 2026](https://www.instagram.com/reel/DcOs3VwRK0B/): Provides prompt-ready design tokens and vocabulary so LLMs generate modern, aesthetic interfaces instead of generic templates.
- [@chase.h.ai, 3 August 2026](https://www.instagram.com/reel/Dblx-7rJUPG/): Produces a portable DESIGN.md specification based on the Google Stitch format and allows in-browser visual editing and tuning of generated UI components.
