cel-tui

Build terminal user interfaces with cel-tui, a TypeScript TUI framework. Use when the user wants to create a TUI app, build a terminal UI, render text in the terminal, create a CLI with interactive elements, build a chat interface, text editor, or any interactive terminal application. Triggers include "build a TUI", "terminal UI", "interactive CLI", "text-based interface", "render to terminal", or any task requiring a programmatic terminal user interface.

Fast, modern JavaScript/TypeScript development with the Bun runtime, inspired by [oven-sh/bun](https://github.com/oven-sh/bun).

Diagnose and fix bugs using a structured, hypothesis-driven process. Use when the user reports a bug, error, unexpected behavior, test failure, crash, or regression. Also use when the user says "this doesn't work", "help me debug", "find the bug", "why is this failing", "this broke", or "track down this issue". Use proactively when you encounter an error during your own work that requires diagnosis beyond a trivial fix.
