## What it is
Impeccable is a design skill and command set for AI coding agents (Claude Code, Cursor, Copilot, Codex, Gemini CLI, etc.) that improves the visual quality of AI-generated frontend interfaces. It ships 23 slash commands, deterministic anti-pattern detector rules runnable without an LLM, live browser iteration, and design hooks that catch regressions as agents edit UI files.

## Use cases
- improve the design of AI-generated landing pages
- remove generic AI design tells like Inter font and purple gradients
- audit a page for accessibility and design anti-patterns
- polish a pricing page before shipping
- critique UI hierarchy and clarity with an AI design review
- iterate on UI variants live in the browser
- lint frontend design automatically when an AI agent edits files

## When to choose
- you use an AI coding agent to build frontend UI and want better design output
- you want deterministic, no-LLM design anti-pattern detection in CI or editor hooks
- you need a shared design vocabulary and workflow (polish, critique, audit) with your coding agent
- you want live in-browser visual iteration that writes accepted variants back to source

## When to avoid
- you don't use an AI coding harness and only want a standalone design tool
- your project is backend-only or has no HTML/component files
- you need pixel-perfect design tooling like Figma rather than agent guidance
- you dislike opinionated design rules imposed on your codebase
