It installs via a single NPX command and works with Claude Code, Cursor, Codex CLI, GitHub Copilot, Kiro, and others. After a one-time init that creates project-specific design.md and product.md files, it provides 23 commands covering the full design workflow — from /impeccable craft (complete UX-to-build flow) to review commands like critique, audit, and polish, plus adjustment dials like bolder, quieter, and colorize. Its standout feature is a deterministic detector system with 41 lint rules that catch AI design clichés (purple-to-blue gradients, Inter font overuse, nested cards, bounce animations) without any LLM calls or API costs, making it CI-pipeline friendly. The tool has over 48,000 GitHub stars and is positioned as structured design guidance rather than a generic prompt pack. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What is the Impeccable design skill and how do I install it for Claude Code or Cursor? Impeccable is an open source, Apache 2.0 licensed design skill that gives AI coding agents a design vocabulary and quality standards for typography, color, spacing, and motion so they stop producing generic 'AI slop' interfaces. It installs with a single command, npx impeccable skills install, which detects your AI tools and sets it up automatically. It works with Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Kiro, and others. _Developers standardizing AI-generated UI quality can track tools like this on daily.dev._ ### How do Impeccable's deterministic detector rules check for AI-generated design patterns without an LLM? Impeccable ships with 41 deterministic detector rules run via npx impeccable detect, pointed at a source folder, a single HTML file, or a live URL, with no LLM call or API key required, so checks are instant and free. The rules catch clichés like purple-to-blue gradients, overused Inter or Arial fonts, cards nested inside cards, rounded icon tiles above headings, bounce easing, and accessibility issues like small touch targets, and support a JSON flag for CI pipelines. _Teams enforcing design quality in CI can follow detector tooling like this via daily.dev._ ### What do the product.md and design.md files created by the Impeccable init command do? Running slash impeccable init creates two project files: product.md, which stores target audience, brand positioning, voice and tone, and anti-references, and design.md, which holds the color palette, typography choices, and component definitions as a design system reference. Every other Impeccable command reads these files first, so the agent follows project-specific design decisions rather than generic advice. _Anyone giving AI agents a proper design spec can keep up with workflows like this via daily.dev._ ## Similar posts on daily.dev - [Skill engineering and the case against one-shot AI design](https://daily.dev/posts/skill-engineering-and-the-case-against-one-shot-ai-design-uxlljwt4r) · Latent Space · 0 upvotes · 0 comments - [Codex is technically better than Claude Code, but I stopped using it for one specific reason](https://daily.dev/posts/codex-is-technically-better-than-claude-code-but-i-stopped-using-it-for-one-specific-reason-e9nmhu5xe) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#ui-design](https://daily.dev/tags/ui-design), [#ai-coding](https://daily.dev/tags/ai-coding) [View this post on daily.dev](https://daily.dev/posts/impeccable-claude-codex-kimi-this-is-one-of-the-best-skills-yet--4vooplqmd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Impeccable + Claude,Codex,Kimi: This is ONE OF THE BEST SKILLS YET!","url":"https://daily.dev/posts/impeccable-claude-codex-kimi-this-is-one-of-the-best-skills-yet--4vooplqmd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/impeccable-claude-codex-kimi-this-is-one-of-the-best-skills-yet--4vooplqmd"},"datePublished":"2026-07-28T09:43:54.490Z","dateModified":"2026-09-13T21:07:02.719Z","description":"Impeccable is a free, open-source design skill for AI coding agents that addresses the generic 'AI slop' aesthetic common in AI-generated frontends.
