Design Lint (Quick Check)

Target: $ARGUMENTS

What This Does

Fast, grep-based scan for common design violations. Runs in seconds (unlike /ss-review which is a deep manual audit). Run this after every file change.

Checks

1. Hardcoded Colors

Search for hex colors in className strings that should be semantic tokens:

bash

grep -n '#[0-9a-fA-F]\{3,8\}' [file] | grep -v 'theme.css\|tokens\|\.json'

Violation: text-[#3C3C3C], bg-[#721FE5] Fix: text-text-primary, bg-brand

2. Raw Pixel Values in Tailwind

bash

grep -n 'p-\[.*px\]\|m-\[.*px\]\|gap-\[.*px\]' [file]

Violation: p-[24px], gap-[12px] Fix: p-6, gap-3

3. Old Width/Height Syntax

bash

grep -n 'w-[0-9] h-[0-9]\|w-\[.*\] h-\[' [file]

Violation: w-4 h-4 Fix: size-4

4. Physical Properties (LTR-only)

bash

grep -n ' ml-\| mr-\| pl-\| pr-' [file]

Violation: ml-2, mr-4 Fix: ms-2, me-4

5. Forbidden Colors

bash

grep -n 'text-black\|bg-black\|#000000\|#000"' [file]

Violation: Any pure black Fix: Use skin's text-primary token

6. Missing data-slot

bash

grep -n 'function [A-Z]' [file] # find components
grep -n 'data-slot' [file]       # check if present

Violation: Component without data-slot Fix: Add data-slot="component-name"

7. Font Size CSS Variables (CRITICAL — Tailwind v4 conflict)

bash

grep -n 'text-\[var(--' [file]
grep -n '\-\-text-.*px\|--fs-.*px' [file]

Violation: text-[var(--text-sm)] or --text-sm: 13px in theme.css Fix: Use explicit text-[13px]. CSS variable font sizes conflict with Tailwind v4's --text-* namespace — Tailwind reads them as color, not font-size.

8. className Without cn()

bash

grep -n 'className={`' [file]

Violation: Template literal className Fix: Use cn() for all className composition
