{"id":95564,"title":"Design Rails: Give your coding agent its own product design team","tagline":"Ship better UX faster with specialized design agents","body":"Hi everyone! We're excited to introduce a set of specialized AI agents that give your coding agent the design expertise it’s missing.\n\n# **Problem**\n\nYou ask Claude or Cursor to build a feature, and you get working code in 2 minutes, but you're stuck with prototype-level design:\n\n* **Visual glitches**: misaligned cards, text bleeding outside containers, buttons cut off\n* **Generic \"AI-feel\" style**: yet another purple gradient that doesn't fit your brand\n* **Flawed UX**: ignored existing navigation pattern, unlabeled icon buttons, missing loading states\n\nYou end up iterating for hours to reach production quality, if you get there at all.\n\n# **Solution**\n\nDesign Rails is an MCP server that connects to AI coding agents (Claude, Codex, Cursor, …) and unlocks production-ready design through three key capabilities:\n\n**1. Design foundation setup** - Design Rails first establishes a strong design foundation to understand your product like a senior designer would:\n\n* Brand \u0026 Design System (extracted from your codebase, or built from scratch)\n* Product Context (what you're building, user personas, key workflows)\n\nThis foundation is captured as .md files in your project. You own the files, version them, and can edit them.\n\n**2. Spec-driven design** - Your coding agent consults Design Rails when facing design decisions. Design Rails orchestrates specialist AI agents including a UX Designer, UI Designer, Accessibility Specialist, and UX Copywriter. Each agent has deep context of your brand, unique design domain expertise, and access to a library of proven patterns from top products.. They work in parallel to produce comprehensive design specs. Your agent gets a detailed blueprint to implement.\n\n**3. Automatic design reviews** - Design Rails spins up a browser to see the rendered results, validating implementation against the spec to catch visual glitches and design inconsistencies before you even see them.\n\n![uploaded image](/media/?type=post\u0026id=95564\u0026key=user_uploads/1010497/4aa73593-8ee3-481f-bcf8-2aaf25f9842c)\n\nSee live before and after examples here: https://designrails.com/#examples\n\n# **Transform glitchy prototypes into production-ready experiences**\n\nTry it out on your existing project, or give it a quick try using an example project we provide as a playground.
