vibe-textual-ui is a skill for Claude Code, Codex from mistralai/mistral-vibe. It costs 52 tokens per session (478 once invoked), scanned A, original, Apache-2.0.

Coding guidance for Textual, a Python framework for terminal user interfaces, and TCSS, its stylesheet language, in Mistral Vibe. It covers widgets, keyboard navigation, tool-result headers, themes, and layout.

In plain words
What is it for?
Use it when building or changing Textual widgets, selectable lists, tool headers, TCSS rules, theme colors, or component layouts in Vibe’s command-line interface.
Why use it?
It prevents inconsistent terminal-interface behavior and styling by defining which components and conventions to use.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vibe-textual-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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.

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.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
