fuzionix/devtool-plus — reverse-engineered prompt

Build me a VS Code extension called DevTool+ that keeps common developer tools inside the editor, so people don’t have to paste private data into random websites.

It should open in a side panel, feel native to the editor theme, and update results instantly as the user types. Everything must run locally with no tracking, no ads, and no network calls for the tools. Include search, categories, and a way to pin favorite tools.

Start with practical tools like Base64, URL encode and parse, ASCII binary and hex, Unicode inspection, HTML entity escaping, color conversion, palette generation, gradients, contrast checking, UUIDs, JSON, YAML, HTML and XML editing, data format conversion, date and time conversion, text diffing, markdown table building, lorem ipsum, slug generation, QR codes, HTTP status codes, data unit conversion, and Unix or Windows path conversion.

Please make it polished enough to install and test locally in VS Code, and look up current extension docs online if needed.
