Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by mistralai on GitHub. Read the source before you install it.

Installation

Install the Vibe Textual Ui AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/mistralai/mistral-vibe/tree/main/.agents/skills/vibe-textual-ui
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/mistralai/mistral-vibe.git /tmp/mistral-vibe
mkdir -p .claude/skills
cp -r /tmp/mistral-vibe/.agents/skills/vibe-textual-ui .claude/skills/vibe-textual-ui

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Vibe Textual Ui in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Vibe Textual Ui on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Vibe Textual Ui is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Vibe Textual UI

Conventions for building and styling Textual TUI widgets in Vibe. Apply when working in vibe/cli/, creating or modifying widgets, or writing TCSS.

The Textual TUI is being deprecated in favor of the Rust TUI (vibe/cli-rust/). Every user-visible change made here must also ship in the Rust TUI in the same PR; see "Terminal UI changes" in the Vibe project AGENTS.md (next to pyproject.toml).

Widgets

For selectable lists, use NavigableOptionList from vibe/cli/textual_ui/widgets/navigable_option_list.py instead of Textual's OptionList. It adds j/k cursor navigation on top of the arrow keys; the bare OptionList only handles arrows.
Keep feature-specific Textual state and helper functions with the feature's widget package. app.py should orchestrate mounting and message handling, not accumulate feature-local state models, defaulting helpers, or import factories.
Render tool headers as an explicit verb plus message in every state: progressive wording while a call is running, then a settled verb once any result arrives, including a failure. Preserve result metadata such as (truncated) or (scratchpad) immediately after the message and keep error details in the expandable result body.

TCSS

When a rule sets color: $text-muted;, pair it with a nested &:ansi { text-style: dim; } so the muted intent survives under ANSI themes.
Never use ansi_* colors (e.g. ansi_red, ansi_bright_blue). Use Textual theme variables like $primary, $foreground, $surface, $error, etc. — see https://textual.textualize.io/guide/design/. ANSI themes are derived from these variables automatically.
Keep truncation and overflow behavior declarative in TCSS. Do not add resize handlers or explicit widget-width calculations solely to force an ellipsis; accept clipping or overflow when Textual cannot express the layout reliably.

Frequently asked questions

What does the Vibe Textual Ui AI skill do?

Why use Vibe Textual Ui on TypingMind?

Because you install it once and use it with any model. Vibe Textual Ui is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Vibe Textual Ui in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/mistralai/mistral-vibe/tree/main/.agents/skills/vibe-textual-ui. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Vibe Textual Ui?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Vibe Textual Ui?

As many as you like. As long as a model supports skills, you can use Vibe Textual Ui with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Vibe Textual Ui AI skill free?

Yes. It is published on GitHub by mistralai under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
