OpenTUI Skill for OpenCode

OpenTUI platform reference docs. Covers the Core imperative API, React reconciler, Solid reconciler, layout system, components, keyboard handling, animations, and testing.

Install

Local installation (current project only):

curl -fsSL https://raw.githubusercontent.com/msmps/opentui-skill/main/install.sh | bash

Global installation (available in all projects):

curl -fsSL https://raw.githubusercontent.com/msmps/opentui-skill/main/install.sh | bash -s -- --global

Usage

Once installed, the skill appears in OpenCode's <available_skills> list. The agent loads it automatically when working on OpenTUI tasks.

Use the /opentui command to load the skill and get contextual guidance:

/opentui create a React TUI with keyboard navigation

Updating

To update to the latest version:

/opentui --update-skill

Structure

The installer adds both a skill and a command:

Decision Trees

The main SKILL.md contains decision trees for:

• Choosing a framework (Core, React, Solid)
• Displaying content (text, containers, code, diffs)
• Handling user input (inputs, keyboard, focus)
• Layout and positioning (flexbox, absolute, responsive)
• Animations (timeline, easing, transitions)
• Testing (snapshots, interaction, debugging)
• Troubleshooting (gotchas, common issues)

Topics Covered

Frameworks: Core (imperative), React (declarative), Solid (fine-grained reactivity)

Components: text, box, scrollbox, input, textarea, select, tab-select, ascii-font, code, line-number, diff

Cross-cutting: Layout (Yoga/Flexbox), Keyboard handling, Animations, Testing

Credits & Inspiration

This skill's structure and patterns are heavily inspired by:

• cloudflare-skill by Dillon Mulroy — an excellent example of a platform skill, demonstrating decision trees, progressive disclosure, and the multi-file reference pattern.

• Anatomy of an Excellent OpenCode Skill by JP Caparas — an insightful breakdown of what makes cloudflare-skill effective, covering context management, troubleshooting indexes, and intent-based routing.
