evondevKit is an open-source skill set (MIT) for AI writing code, helping AI to build app interfaces like a designer: dashboard, list, table, form, settings page, modal.

Problem Solved

Thanks to AI creating UI, it often results in a runnable screen but looks cluttered: random colors, uneven spacing, breaks on mobile, and each screen looks different. This skill provides AI with a set of rules regarding colors, text, spacing, states, and screens to create a neat and consistent interface from the start.

Main Features

• Acts like a designer: write a brief for your approval, present 2–3 wireframes with real content (color on, view mobile version, check empty/error states), and only after your selection does it build.
• Build the design system first: tokens and basic components (button, input, card, modal…) for the later screens to share a single set.
• Analyze the existing UI: automatically open pages at various widths, measure offset errors, overflow, contrast, and then provide an error table along with before/after images. You select which lines to fix.
• Rebuild while maintaining the brand, or refactor CSS while keeping the original appearance.
• Adhere strictly to the project's component library and color (shadcn, MUI, internal kit), without adding another set on top.

Who Should Use It

Frontend developers and product managers who are using AI to build management apps, SaaS, internal tools without accompanying designers.

How to Get Started

Claude Code: /plugin marketplace add evondev/evondevKit, then /plugin install evon@evondevkit, call using /evon:ui-ux.

Cursor, OpenCode, Codex, Antigravity: npx skills add evondev/evondevKit.

You can write in Vietnamese or English.

What Makes It Different

This skill is not just a set of prompts: it includes a script to open real pages, measure errors numerically, and auto-fix before delivering. The rules are derived from around 70 test cases on real projects.

The skill is currently in beta and not perfect. Everyone has different tastes, and every project has its own uniqueness, so after building, feel free to adjust things manually or ask the AI for further fixes. If you encounter any issues, please open a ticket on GitHub to help me out.
