Impeccable

An open-source Claude Code skill optimized for frontend design. Ships with 17 commands to improve AI-generated UIs beyond the default “purple gradient” vibe-coded aesthetic.

Commands

Notable commands include:

• distill — simplify an overly complex UI in one go
• colorize — apply brand colors
• animate — add motion
• delight — add polish and uniqueness

Why It Exists

A common complaint about vibe-coded apps: they all look the same. Impeccable addresses this by giving Claude Code a structured set of design-focused operations that can be applied incrementally to make UIs look distinctive and professional.

Compared to Google Stitch
