Animated Interactive Rust CLI (crossterm + ratatui)

An interactive terminal launcher for multi-component projects, written in Rust. Provides a sine-wave animated ASCII banner, keyboard-driven menu with number shortcuts, real-time build progress with streamed output, a warning summary screen with severity colours, scrollable command viewers, and clipboard support — using only crossterm and ratatui.

When to Use This Skill

• Creating a developer CLI that wraps build/test/launch operations for a project
• When you want animated feedback during long build processes
• When the project has multiple independently-buildable components (e.g. Rust + Python + linting)
• When you want a native compiled binary instead of a PowerShell script for the CLI launcher
• When targeting Windows terminals (handles key-release ghost events)
