The missing design
vocabulary for agents.

It's why AI frontends all share one look: no words for hierarchy, contrast, or restraint. Impeccable gives your agent the designer's vocabulary, and gives you the same commands, so you both stop guessing and start directing, live, in your production codebase.

It fucking works beautifully. It's so cool.

Impeccable > Claude design

BERJAYAMertcan Yüzer@MertcanDYuzer

Uninstall whatever frontend skill you're using. Replace it with Impeccable.

BERJAYAAdrien Ninet@adrien_ninet

Impeccable is the most slept on tool for incorporating design thinking into coding workflows.

BERJAYAAnish Acharya@illscience

When anyone asks me about design for frontend I always recommend @impeccable_ai plugin. I'm very picky with design and it's become part of my everyday stack.

BERJAYACathryn Lavery@cathrynlavery

This is probably what Figma Make should be.

BERJAYAIan Andrews@IanAndrewsDC

Impeccable is hands down the best UI design skill out there. I use it daily and recommend it to others as well. Great work! 💪

BERJAYACarl Rannaberg@carlrannaberg

It has taken my ability to ship complex and beautiful designs to another level.

BERJAYABowTiedGroundHog@BowTiedGroundHo

Impeccable is the best skill I've used this year. Can't believe it's free.

BERJAYAIvan Leo@ivanleomk

Impeccable is so so good. I love it.

BERJAYAWatson Cyrus Anikwai@wanikwai

I will fight anyone who say anything bad against impeccable, just let me know who they are.

BERJAYAFaizan Khan@faizan10114

I've tried and used many UI design tools that enhance AI aesthetics, and this one is the best and most stunning I've ever used.

BERJAYAHickerzed@Hicker_Moledao

BERJAYATony Ge@largePrawn

@impeccable_ai is really good and is the first time I really felt a 10x productivity boost with AI. And I make an effort to try as many tools as possible.

BERJAYAThomas Karatzas@karatzas_thomas

TIL you are the guy behind Impeccable. I owe like 3 customer conversions to you. Thank you for such an amazing tool.

BERJAYAFaizan Khan@faizan10114

Shipped a landing page in 2 hours using @conductor_build & @impeccable_ai. From idea to prod faster than most people pick a font ;))

BERJAYAServando@vandotorres

This is the best plugin ever created imo.

BERJAYAVishveshwar Jatain@eclecticV

Claude skills are mostly BS. These ones are the rare, truly useful ones.

BERJAYANik@nik_ska

How is this free?? 🔥🔥

BERJAYAZohaib A.@HeyZohaib

It's crazy that @impeccable_ai is free. It replaces some paid products while being better than them.

BERJAYASankalp Mukim@IceCreamChai

@impeccable_ai has been a huge help at all levels from prototyping to production. It has really upped our game. I can't see anything out-of-the-box like this replacing it.

BERJAYAMichael Hedgpeth@michaelhedgpeth

Impeccable is the best frontend design skill I've used rn. It clears the alternatives by a mile.

BERJAYAmartta_xu@littlemartta

This is incredible. Developer and Designer workflows are changing so quickly and for the better.

BERJAYAPaul Kinlan@Paul_Kinlan

Recently used this skill for my personal portfolio and was blown away. Iterated multiple times on Claude code and hardly touched Figma.

BERJAYAJashan Gupta@JASHANGUPTA15

This is 🔥. My landing page looked 100% vibe coded. I think it looks very decent now. I had fun in the process.

BERJAYASidney Hori Hawthorne@sid_hori

I'm glad that we never need to touch Figma again. Just run 8 agents using @paper w/ Impeccable's Claude skills.

BERJAYAbillzh@billzh

Impeccable is such a great skill. I use it multiple times a day every day and it makes a huge difference.

BERJAYAJohn Ennis@johnennis

Upgraded an internal tool with better UI, UX, branding and reduced AI slop. This established a standard for the project itself.

BERJAYASomesh@devsome_sh

It's so good.

BERJAYAAlejandro Reyes@alejandroreyes

This is the only set of agent skills I ever found use in. Thanks for making this.

Desloppification

Impeccable strips the AI slop tells and bad defaults out of every design discipline, from type to motion to copy. A skill can't make the model a better designer; it can clear the reflexes that make its output look generated.

The Language

23 commands give you a shared design vocabulary with your AI. Each maps to one discipline (/typeset for type, /colorize for color, /animate for motion), so you can ask for the exact thing without explaining it. Pick any to see it in action, or browse the full reference →

01

Respects your design system.

Inherits your tokens, components, and conventions instead of overwriting them. New work fits the system, not the model's defaults.

Real product context.

Captures the brief once, in PRODUCT.md. Every command reads it before designing.

Tuned to the agent you actually use.

Plays to each agent's strengths and around its weaknesses. Below: Codex used image generation to draft Neo Mirai before /impeccable craft turned it into shipped code.

01 · VisualizeAuto-generated hi-fi landing-page mock in editorial warm-paper style.
02 · ShapeAuto-generated brand toolkit: identity lockups, palette, type, icon system, and application mocks for a fictional AI design conference.

Brand work is not product UI.

A landing page and a dashboard play by different rules. Impeccable runs in two registers, brand or product, and every command knows which.

A detector you can wire into PR checks. 44 deterministic rules, no LLM, exit codes the build can read.

Get started

Install via

On the GitHub Copilot app? Impeccable is built in. Skip the install and enable it under Settings → Experimental.

npx impeccable install

Installs the build tailored to your harness and model. Requires Node 24+.

Why one command, many builds
impeccableClaude Codehooks + subagentCursorpre-edit hookGemini CLI+ Gemini-tuned slop rulesCodex CLI+ Codex-tuned slop rules

Same skill, recompiled per target. The part that matters: builds for models with known tells carry extra slop rules banning that model's habits. The Gemini build kills its image-on-hover motion; the Codex build refuses ghost-cards and over-rounding. Native hook wiring and a subagent ship too, where the tool supports them.

First run
/impeccable init
Update
npx impeccable update

Works with Cursor, Claude Code, GitHub Copilot, Gemini CLI, Codex CLI, and every other major AI coding harness.
