## What it does

The plugin installs one skill, `impeccable`, with a single entry point: `/impeccable <command> <target>`. There are 24 commands, from `shape` and `craft` to `harden`, `typeset` and `live`. It also ships a list of anti-patterns: no Inter everywhere, no gray text on colored backgrounds, no cards nested in cards, no pure black.

Start with `/impeccable init`. It inspects the project, asks only about gaps in durable product truth, and writes `PRODUCT.md` — audience, purpose, constraints, voice. Visual direction lives separately in `DESIGN.md`. Later commands read those files, so advice doesn't confuse product facts with surface styling.

Install with `npx impeccable install` from your project root. The installer detects harness folders, asks about providers and scope. Node is only needed for that installer — the skill itself runs through a small launcher and a binary downloaded on first run into `~/.impeccable/bin/`. On Claude it also drops a native hook manifest, so reload your harness afterwards.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install impeccable@claude-community
```

## When to use it
- strip the same SaaS template look out of a frontend
- check a11y and responsive behaviour before shipping
- tone down an interface that leans too hard on color
- fill in empty states and first-run flows
- fix font choices and vertical rhythm

## Example prompts
- /impeccable init
- /impeccable audit blog
- /impeccable critique landing

# Impeccable

Design guidance for AI coding agents. 1 skill, 24 commands, live browser iteration, and 62 deterministic detector rules for AI-generated frontend design.

> **Quick start:** From your project root, run `npx impeccable install`, then run `/impeccable init` inside your AI coding tool. Full docs: [impeccable.style](https://impeccable.style).

## Why Impeccable?

Anthropic's [frontend-design](https://github.com/anthropics/skills/tree/main/skills/frontend-design) was the first widely-used design skill for Claude. Impeccable started from there.

Every model trained on the same SaaS templates. Skip the guidance and you get the same handful of tells on every project: Inter for everything, purple-to-blue gradients, cards nested in cards, gray text on colored backgrounds, the rounded-square icon tile above every heading.

Impeccable adds:
- **One setup flow.** `/impeccable init` records durable product truth in `PRODUCT.md`, so later commands know the audience, purpose, operating context, constraints, voice, and evidence without confusing those facts with surface-level visual direction.
- **24 commands.** A shared design vocabulary with your AI: `polish`, `audit`, `critique`, `distill`, `animate`, `bolder`, `quieter`, and more.
- **62 deterministic detector rules** plus LLM-only critique checks. The CLI and browser extension run the deterministic rules with no LLM and no API key.

## What's Included

### The Skill: impeccable

The skill installs as one command:

```bash
/impeccable <command> <target>
```

Start every new project with:

```bash
/impeccable init
```

`init` inspects the project, asks only for material gaps in durable product truth, and writes `PRODUCT.md`. Visitor mode and visual direction are chosen later for each surface; incumbent or newly built visual systems are recorded separately in `DESIGN.md`.

### 24 Commands

All commands are accessed through `/impeccable`:

| Command | What it does |
|---------|--------------|
| `/impeccable craft` | Full shape-then-build flow with visual iteration |
| `/impeccable init` | One-time setup: gather durable product context, write PRODUCT.md, configure live mode when applicable, recommend next steps |
| `/impeccable document` | Generate root DESIGN.md from existing project code |
| `/impeccable extract` | Pull reusable components and tokens into the design system |
| `/impeccable shape` | Plan UX/UI before writing code |
| `/impeccable critique` | UX design review: hierarchy, clarity, emotional resonance |
| `/impeccable audit` | Run technical quality checks (a11y, performance, responsive) |
| `/impeccable polish` | Final pass, design system alignment, and shipping readiness |
| `/impeccable bolder` | Amplify boring designs |
| `/impeccable quieter` | Tone down overly bold designs |
| `/impeccable distill` | Strip to essence |
| `/impeccable harden` | Error handling, i18n, text overflow, edge cases |
| `/impeccable onboard` | First-run flows, empty states, activation paths |
| `/impeccable animate` | Add purposeful motion |
| `/impeccable colorize` | Introduce strategic color |
| `/impeccable typeset` | Fix font choices, hierarchy, sizing |
| `/impeccable layout` | Fix layout, spacing, visual rhythm |
| `/impeccable delight` | Add moments of joy |
| `/impeccable overdrive` | Add technically extraordinary effects |
| `/impeccable clarify` | Improve unclear UX copy |
| `/impeccable adapt` | Adapt for different devices |
| `/impeccable optimize` | Performance improvements |
| `/impeccable live` | Visual variant mode: iterate on elements in the browser |
| `/impeccable generate` | Generate variants of a named element in the live browser, no manual picking |

Use `/impeccable pin <command>` to create standalone shortcuts (e.g., `pin audit` creates `/audit`).

#### Usage Examples

```
/impeccable audit blog           # Audit blog hub + post pages
/impeccable critique landing     # UX design review
/impeccable polish settings      # Final pass before shipping
/impeccable harden checkout      # Add error handling + edge cases
```
