About this skill
Overview
Nex Color Spy is a production-ready, Manifest V3 Chrome extension designed for designers and front-end developers who need instant access to computed styles. Unlike generic AI scripts, this skill provides the complete source code for a field-tested "overlay" extension that inspects colors, fonts, and box model data in real-time without interfering with page styles.
What it does
- Shadow-DOM Overlay: Features a floating inspector panel isolated from host page CSS to ensure consistent UI rendering.
- Real-time Inspection: Tracks the cursor to report computed hex codes, font families, font sizes, margins, and padding.
- Zero-Build Architecture: Written in vanilla JS, HTML, and CSS. No Webpack, Vite, or NPM required—just edit and reload.
- Clipboard Integration: Quick-click functionality to copy any hex code or CSS value directly to the clipboard.
Why use this skill?
Prompting an AI to "write an extension" often results in broken background scripts or styling conflicts. This skill delivers a battle-hardened codebase optimized for the MV3 lifecycle. It includes keyboard shortcuts (Alt+Shift+I), storage persistence for settings, and a professional-grade content script that handles complex page layouts effortlessly. Use it to ship a finished tool immediately or as a robust template for your own overlay-based extensions.
Supported Features
- Manifest V3 compliant (Service Workers).
- Isolation via Shadow-DOM.
- Keyboard-driven toggles and toolbar actions.
- Ready-to-zip packaging for the Chrome Web Store.
