wren-engine vs design-extract
wren-engine: Wren Engine is an open context engine for AI agents that transforms business data into agent-usable context. It captures business definitions, metrics, relationships, and access rules, enabling agents to understand models and generate accurate queries. The engine supports MCP, HTTP APIs, and can be embedded into various agent workflows.; 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.
