flawless-ui-ux

flawless-ui-ux is an MIT-licensed design skill for coding agents such as Codex, Claude Code, Cursor and OpenCode that guides them to build less generic, more usable interfaces, plus a CLI that inspects a running app and checks whether fixes worked.

Why it matters

For people building apps with AI coding agents, it targets the familiar problem of look-alike, generic interfaces, and adds a way to check accessibility and layout issues instead of trusting the agent's word.

Highlights

• Supports twelve agents, including Codex, Claude Code, Cursor, OpenCode, Kiro, GitHub Copilot CLI, Devin and Grok Build, installed with one npx command.
• Covers creating, redesigning, refining and reviewing interfaces, tied to your product's audience, content and brand.
• The CLI inspects source files or a running app for contrast and accessible-name problems, font sizes, overflow, broken images and JavaScript errors.
• A verify command compares before and after runs, separating persistent, new and resolved findings.
• Inspection doesn't edit files or submit forms; your agent makes the changes.
