Handler vs design-extract
Handler: Handler is an open-source A2A protocol client for your terminal. It provides a TUI and CLI to send messages, manage tasks, and inspect agent cards. An included MCP server lets AI assistants communicate with A2A agents.; design-extract: designlang is a unique tool that crawls any website with a headless browser to extract comprehensive computed styles, layout patterns, motion language, component anatomy, and brand voice from the live DOM. It generates over 17 distinct output files, including AI-optimized markdown, Tailwind config, React themes, and Figma variables, enabling precise capture and translation of a site's visual DNA. Users can leverage it for tasks like design system scoring, codebase drift-checking against live sites, and visual comparison of multiple URLs or brands.
