Claude Code Skill Converts Stitch Designs to Next.js with Zero Pixel Drift

What This Tool Does

A Claude Code skill (slash command) converts Google Stitch AI designs to Next.js components while preventing the pixel drift that typically occurs when using Claude for this task. The tool addresses specific pain points where Claude would round values like text-[15px] to text-sm, swap exact colors like #1E293B for approximate Tailwind classes like bg-slate-800, lose image assets due to expired CDN URLs, or miss fonts.

Key Features and Process

• Extracts exact HTML/CSS from Stitch via MCP - no copy-pasting or screenshots
• Preserves exact pixel values throughout (text-[15px] stays text-[15px], not rounded to a Tailwind class)
• Downloads all images from the Stitch CDN before URLs expire
• Maps all 29 Stitch fonts to next/font/google properly
• Includes 5 mandatory verification checkpoints that compare output against source before moving on
• Generates a full audit report showing exactly what was preserved and what needed judgment calls
• Supports ShadCN/UI component mapping with exact style overrides

Installation and Setup

Install with: curl -sL https://raw.githubusercontent.com/yshaish1/stitch-to-nextjs/main/install.sh | bash

The installation also auto-configures the stitch-mcp server automatically.

Why Verification Checkpoints Are Necessary

The verification checkpoints address Claude's tendency to drift toward Tailwind conventions when left to its own devices. The skill's prompt explicitly flags this pattern and forces re-verification at each stage. While not foolproof, this approach catches common failure modes before they compound.
