Things people build with this

USE CASE 1

Ask your AI assistant to polish a generated UI using the 'polish' command to get a more distinctive design.

USE CASE 2

Run the CLI tool to scan your HTML website for common design anti-patterns and get automated feedback.

USE CASE 3

Use the 'animate' and 'bolder' commands to add motion and visual emphasis to AI-generated interfaces.

USE CASE 4

Reference the typography and color guides when prompting your AI assistant to ensure consistent, professional styling.

In plain English

Impeccable is a design language and skill pack that improves the quality of UI (user interface) designs produced by AI coding assistants. It solves a common problem: when you ask an AI tool to build a front-end (the visual part of a website or app), you tend to get the same generic-looking result every time, the same fonts, the same purple-to-blue gradients, the same cards-inside-cards layout. The library works by giving your AI assistant a shared vocabulary and specific rules. It installs into AI coding tools like Claude Code, Cursor, GitHub Copilot, and Gemini CLI, then activates 23 commands (such as "polish", "audit", "critique", "animate", and "bolder") that you can invoke while building. Behind the scenes, 7 reference documents cover areas like typography (font choices and sizing), color and contrast, spacing, motion, interaction patterns, responsive design, and UX writing. A set of 27 deterministic anti-pattern rules, meaning rules that don't need an AI to check, just code scanning, catches common design mistakes automatically. You would use Impeccable when you are a developer or vibe coder (someone who builds with AI tools) who wants the AI to produce polished, distinctive designs instead of generic-looking templates. A standalone command-line tool is also included for scanning HTML files or websites for design anti-patterns without needing an AI assistant. The tech stack is JavaScript.

I have an HTML file. Use Impeccable's CLI to scan it for design anti-patterns and tell me what needs fixing.
Prompt 3
What are the 23 commands in Impeccable and which ones should I use to make my AI-generated landing page look less generic?
Prompt 4
Show me how to use Impeccable's typography and spacing reference documents to prompt Claude Code for better UI designs.
Prompt 5
Can you help me set up Impeccable in GitHub Copilot so it suggests design improvements as I code?
