Perfect for Terminal UI Automation Agents needing streamlined workflows with decision trees and framework references. OpenTUI is a terminal UI automation tool for coding agents, helping developers streamline workflows with decision trees and framework references. It supports agents like Claude Code, Cursor, and Windsurf.

How do I install opentui?

Run the command: npx killer-skills add nitodeco/ralph/opentui. It works with Cursor, Windsurf, VS Code, Claude Code, and 19+ other IDEs.

What are the use cases for opentui?

Key use cases include: Automating terminal UI workflows, Generating framework references for React and Solid, Debugging terminal UI applications with OpenTUI's gotchas guide.

Which IDEs are compatible with opentui?

This skill is compatible with Cursor, Windsurf, VS Code, Trae, Claude Code, OpenClaw, Aider, Codex, OpenCode, Goose, Cline, Roo Code, Kiro, Augment Code, Continue, GitHub Copilot, Sourcegraph Cody, and Amazon Q Developer. Use the Killer-Skills CLI for universal one-command installation.

Are there any limitations for opentui?

Requires Bun and Zig for native builds. Must follow specific critical rules, such as using `create-tui` for new projects and avoiding direct calls to `process.exit()`.

OpenTUI Platform Skill

Name: opentui
Availability: InStock
Author: nitodeco

Consolidated skill for building terminal user interfaces with OpenTUI. Use decision trees below to find the right framework and components, then load detailed references.

Critical Rules

Follow these rules in all OpenTUI code:

Use create-tui for new projects. See framework REFERENCE.md quick starts.
create-tui options must come before arguments. bunx create-tui -t react my-app works, bunx create-tui my-app -t react does NOT.
Never call process.exit() directly. Use renderer.destroy() (see core/gotchas.md).
Text styling requires nested tags in React/Solid. Use modifier elements, not props (see components/text-display.md).

How to Use This Skill

Reference File Structure

Framework references follow a 5-file pattern. Cross-cutting concepts are single-file guides.

Each framework in ./references/<framework>/ contains:

File	Purpose	When to Read
`REFERENCE.md`	Overview, when to use, quick start	Always read first
`api.md`	Runtime API, components, hooks	Writing code
`configuration.md`	Setup, tsconfig, bundling	Configuring a project
`patterns.md`	Common patterns, best practices	Implementation guidance
`gotchas.md`	Pitfalls, limitations, debugging	Troubleshooting

Cross-cutting concepts in ./references/<concept>/ have REFERENCE.md as the entry point.

Reading Order

Start with REFERENCE.md for your chosen framework
Then read additional files relevant to your task:
- Building components -> api.md + components/<category>.md
- Setting up project -> configuration.md
- Layout/positioning -> layout/REFERENCE.md
- Keyboard/input handling -> keyboard/REFERENCE.md
- Animations -> animation/REFERENCE.md
- Troubleshooting -> gotchas.md + testing/REFERENCE.md

Example Paths

./references/react/REFERENCE.md           # Start here for React
./references/react/api.md              # React components and hooks
./references/solid/configuration.md    # Solid project setup
./references/components/inputs.md      # Input, Textarea, Select docs
./references/core/gotchas.md           # Core debugging tips

Runtime Notes

OpenTUI runs on Bun and uses Zig for native builds. Read ./references/core/gotchas.md for runtime requirements and build guidance.

Quick Decision Trees

"Which framework should I use?"

Which framework?
├─ I want full control, maximum performance, no framework overhead
│  └─ core/ (imperative API)
├─ I know React, want familiar component patterns
│  └─ react/ (React reconciler)
├─ I want fine-grained reactivity, optimal re-renders
│  └─ solid/ (Solid reconciler)
└─ I'm building a library/framework on top of OpenTUI
   └─ core/ (imperative API)

"I need to display content"

Display content?
├─ Plain or styled text -> components/text-display.md
├─ Container with borders/background -> components/containers.md
├─ Scrollable content area -> components/containers.md (scrollbox)
├─ ASCII art banner/title -> components/text-display.md (ascii-font)
├─ Code with syntax highlighting -> components/code-diff.md
├─ Diff viewer (unified/split) -> components/code-diff.md
├─ Line numbers with diagnostics -> components/code-diff.md
└─ Markdown content (streaming) -> components/code-diff.md (markdown)

"I need user input"

User input?
├─ Single-line text field -> components/inputs.md (input)
├─ Multi-line text editor -> components/inputs.md (textarea)
├─ Select from a list (vertical) -> components/inputs.md (select)
├─ Tab-based selection (horizontal) -> components/inputs.md (tab-select)
└─ Custom keyboard shortcuts -> keyboard/REFERENCE.md

"I need layout/positioning"

Layout?
├─ Flexbox-style layouts (row, column, wrap) -> layout/REFERENCE.md
├─ Absolute positioning -> layout/patterns.md
├─ Responsive to terminal size -> layout/patterns.md
├─ Centering content -> layout/patterns.md
└─ Complex nested layouts -> layout/patterns.md

"I need animations"

Animations?
├─ Timeline-based animations -> animation/REFERENCE.md
├─ Easing functions -> animation/REFERENCE.md
├─ Property transitions -> animation/REFERENCE.md
└─ Looping animations -> animation/REFERENCE.md

"I need to handle input"

Input handling?
├─ Keyboard events (keypress, release) -> keyboard/REFERENCE.md
├─ Focus management -> keyboard/REFERENCE.md
├─ Paste events -> keyboard/REFERENCE.md
├─ Mouse events -> components/containers.md
└─ Text selection -> components/text-display.md

"I need to test my TUI"

Testing?
├─ Snapshot testing -> testing/REFERENCE.md
├─ Interaction testing -> testing/REFERENCE.md
├─ Test renderer setup -> testing/REFERENCE.md
└─ Debugging tests -> testing/REFERENCE.md

"I need to debug/troubleshoot"

Troubleshooting?
├─ Runtime errors, crashes -> <framework>/gotchas.md
├─ Layout issues -> layout/REFERENCE.md + layout/patterns.md
├─ Input/focus issues -> keyboard/REFERENCE.md
└─ Repro + regression tests -> testing/REFERENCE.md

Troubleshooting Index

Terminal cleanup, crashes -> core/gotchas.md
Text styling not applying -> components/text-display.md
Input focus/shortcuts -> keyboard/REFERENCE.md
Layout misalignment -> layout/REFERENCE.md
Flaky snapshots -> testing/REFERENCE.md

For component naming differences and text modifiers, see components/REFERENCE.md.
