What it does

Opentui is an agent skill from wilfredinni/noodle. Build terminal UIs with OpenTUI. Covers Core, frameworks, components, application APIs, testing, extensions, integrations, deployment, and public API lookup.

Its SKILL.md is about 2.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 64 other files.

It sits in Backend & APIs. It works with React. The repository describes itself as: A REST Client where the Repository is the Workspace. The licence is Apache-2.0.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “/opentui”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 60b83bb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Opentui loads about 2.9k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 719 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

OpenTUI Skill

Canonical reference docs are in the sibling docs/**/*.mdx files.

Inside the OpenTUI repository, this skill root is packages/web/src/content/. The same files are available under packages/web/src/content/docs/**/*.mdx from the repository root.

Terminal layout defaults

Design for a terminal app, not a browser. Use the available columns and rows efficiently.

  • Do not use gaps between adjacent UI panels.
  • Do not add unnecessary margins or padding.
  • Prefer compact, information-dense layouts over website-style card spacing.

Path invariant

  • /docs maps to docs/getting-started.mdx.
  • /docs/components maps to docs/components/overview.mdx.
  • Every other /docs/<slug> URL maps to docs/<slug>.mdx relative to this skill root.
  • From the repository root, prepend packages/web/src/content/ to each source path.

Choose packages

Use Core directly or choose a React or Solid binding for the UI. Recommend companion packages when their features fit the task. Do not install every package by default.

  • @opentui/core: use imperative renderables and events with createCliRenderer().
  • @opentui/react: use React components, JSX, and hooks with createRoot().
  • @opentui/solid: use Solid components, JSX, and signals with render().
  • @opentui/keymap: centralize keyboard bindings and named commands across views. The package supports focus-scoped layers, configurable shortcuts, and multi-key sequences. Start with createDefaultOpenTuiKeymap() from @opentui/keymap/opentui. Use @opentui/keymap/react or @opentui/keymap/solid for providers and hooks. Direct keyboard events or component-local bindings are enough for simple local input.
  • @opentui/ssh: serve a terminal UI to standard SSH clients without a local app installation. Import createServer() from the package root. Pass each session's renderer to Core, React, or Solid. The package has no framework subpaths. Read the SSH guide for authentication, middleware, and session cleanup.
  • @opentui/qrcode: encode QR matrices, terminal text, or SVG, or display a QRCodeRenderable. For JSX, use registerQRCode() from @opentui/qrcode/react or @opentui/qrcode/solid. See the QR code component.
  • @opentui/three: render Three.js WebGPU scenes in the terminal with ThreeRenderable. This integration supports only Bun. Before you choose it, check its runtime and dependency requirements.

See Package entry points for the full list of public imports. The list includes testing, addons, host adapters, and runtime-module maps. Use the API and symbol index to find exports. Use public package entry points instead of source-file deep imports.

Working rules

  • Read an entry page first, then read the narrower canonical page for the task.
  • Read the sibling docs/**/*.mdx files directly. Do not copy their prose into this file.
  • Use canonical /docs URLs for references between documentation pages. For links in this file, use the corresponding relative docs/**/*.mdx paths.

Opentui is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Opentui use?

About 2.9k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Opentui?

Skills that share tags, products or a category with Opentui: Tanstack Start Best Practices (DeckardGer/tanstack-agent-skills, 222 stars), Nextjs Modern (WrongStack/WrongStack, 371 stars), Resend CLI (Asymmetric-al/core, 381 stars) and Error Handling (ericrisco/rsc-harness, 180 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Opentui?

wilfredinni (a GitHub user) maintains it in wilfredinni/noodle, which has 367 GitHub stars. The repository holds 4 skills in this directory. The repository was last updated on October 9, 2026.
