Paul Bakaus 6dd16d21ef CLI: turn the impeccable npm package into a platform-binary shim
cli/engine, cli/lib, and cli/bin/commands are gone; their behavior lives in
the engine binary. cli/bin/cli.js now resolves the binary from IMPECCABLE_BIN,
the @impeccable/cli-<os>-<arch> optional dependency (templates under
cli/platform-packages/, published by the engine release), the
~/.impeccable/bin/<version>/ cache, or a checksum-verified download, and
execs it. package.json drops the engine dependencies and the library
exports; puppeteer moves to devDependencies for the icon scripts.
README.npm.md describes the shim.

Prepared with AI assistance (Claude Code).

# Impeccable CLI
Detect UI anti-patterns and design quality issues from the command line, and install the Impeccable design skill into your AI coding harness. The detector scans HTML, CSS, JSX, TSX, Vue, and Svelte files for 59 deterministic rules, including AI-generated UI tells, accessibility violations, and general design quality problems.
The npm package is a small launcher. It runs the `impeccable` engine binary for your platform, installed alongside it as an optional dependency (`@impeccable/cli-<os>-<arch>`), and falls back to a per-user cache or a one-time download when that package is missing.
## Quick Start
```bash
# Install skills into your AI harness (Claude, Cursor, Gemini, etc.)
npx impeccable install
# Non-interactive install for a specific scope
npx impeccable install -y --providers=claude,codex --scope=project
# First command to run inside your AI harness
/impeccable init
# Update skills to the latest version
npx impeccable update
# Install or update skills without hook manifests
npx impeccable install --no-hooks
# Link skills from a Git submodule checkout
npx impeccable link --source=.impeccable --providers=claude,cursor
# List all available commands
npx impeccable help
# Scan files or directories for anti-patterns
npx impeccable detect src/
# Scan a live URL (uses an installed Chrome, Chromium, or Edge)
npx impeccable detect https://example.com
# JSON output for CI/tooling
npx impeccable detect --json src/
```
`npx impeccable skills <command>` is the legacy namespace and still works.
## What It Detects
**AI Slop Tells**: patterns that scream "AI generated this":
- Side-tab accent borders, gradient text on headings
- Purple/violet gradients and cyan-on-dark palettes
- Dark mode with glowing accents, border + border-radius clashes
**Typography Issues**: overused fonts (Inter, Roboto), flat type hierarchy, single font families
**Color & Contrast**: WCAG AA violations, gray text on colored backgrounds, pure black/white
**Layout & Composition**: nested cards, monotonous spacing, everything-centered layouts
**Motion**: bounce/elastic easing, layout property transitions
**Quality**: tiny body text, cramped padding, long line lengths, small touch targets
61 deterministic detector rules in total. See the full catalog at [impeccable.style/slop](https://impeccable.style/slop).
## Exit Codes
- `0`: no issues found
- `2`: anti-patterns detected
## Options
```
impeccable detect [options] [file-or-dir-or-url...]
--json Output findings as JSON
--scope Only report rules in a design domain (type, layout)
--help Show help
```
## Requirements
- Node.js 22.18+ to run `npx impeccable`. The engine itself is a self-contained binary and needs no runtime; the skill installed into your harness calls it directly.
- For URL scans, an installed Chrome, Chromium, or Edge (set `IMPECCABLE_BROWSER` to point at one).
Binary lookup order: `IMPECCABLE_BIN`, the platform package, `~/.impeccable/bin/<version>/`, then a download of the pinned version into that cache. Set `IMPECCABLE_BIN` to a local build to skip all of that.
## Part of Impeccable
This CLI is part of [Impeccable](https://impeccable.style), a cross-provider design skill pack for AI-powered development tools. The full suite includes 23 commands for Claude, Cursor, GitHub Copilot, Gemini, Codex, Hermes Agent, Veto, and more.
