Example session with this skill installed
I need a Chrome extension that strips UTM parameters and hidden characters when I copy text.
- Read your context and instructions
- Compiled the nex-clean-copy-ext
I've generated the 'assets/extension/' folder with the full Manifest V3 source. You can now load this as an 'unpacked extension' in Chrome. It includes cleaner.js for stripping tracking params and content.js for clipboard interception. To test, just copy a URL with ?utm_source=test attached.
Connects securely to your tools. The creator never sees your data.
About this skill
What it does
This skill provides the complete, production-ready source code for the Nex Clean Copy Chrome extension. It implements a sophisticated content-rewriter pipeline that intercepts copy events to strip away hidden junk. It automatically removes zero-width characters (BOM, soft hyphens, joiners), invisible Unicode directional marks, and invasive URL tracking parameters like utm_*, fbclid, and gclid.
Why use this skill
While generic AI prompts can help you write individual functions, this skill delivers a fully integrated Manifest V3 architecture that is already tested and "shipped." It follows a high-performance vanilla JS/HTML/CSS pattern with zero build steps, meaning no npm overhead or transpilation is required. It's the perfect technical foundation for developers who need a working content-rewriter archetype to fork, customize, and deploy immediately.
Supported Features
- Manifest V3 Compliant: Uses the latest Chrome extension standards.
- Modular Cleaning Pipeline: Dedicated logic for Unicode stripping and URL parameter filtering.
- UI Included: Full popup and settings pages for user-toggled cleaning categories.
- No-Build Workflow: Edit and reload directly in the browser for instant feedback.
- Store Ready: Includes packaging instructions and manifest configurations for the Chrome Web Store.
