Using the Claude app rather than Claude Code? You can add a skill there too. How to add it in the app

What does opentui do?

opentui is a Claude skill for building terminal user interfaces with OpenTUI, which runs on Bun. It opens with four rules: scaffold with create-tui, put its options before the project name, never call process.exit() but use renderer.destroy(), and style text with nested modifier tags in React or Solid. Decision trees then point Claude to the right reference file for choosing Core, React or Solid, showing text, code diffs and markdown, inputs and selects, flexbox layout, keyboard and keymaps, animation, clipboard, audio, serving over SSH and snapshot testing. Each framework has REFERENCE, api, configuration, patterns and gotchas files.

When should you use opentui?

Use it when

  • You are starting a new TUI app with create-tui
  • You need keyboard shortcuts or focus handling in a TUI
  • You want snapshot tests for terminal screens

Skip it when

  • Your terminal UI uses another library
  • You can't use Bun in your project

What it needs and what it can touch

You need

  • Bun

What it can do

  • Reads and edits project files
  • Runs shell commands (bunx create-tui)

From reading its instructions, not from running it.

How the formula works

Is opentui safe to install?

Every scanner that checked it passed it. Scanners often miss what other scanners catch, and a skill can change after a scan. Read its source before you install it.
