README

textual-healing

A [Claude Code](https://claude.com/claude-code) skill for building, testing and visually verifying terminal UIs with [Textual](https://textual.textualize.io/) (Python).

Verified against **Textual 8.2.8** (September 2026). The skill checks the installed version first and points to a version-drift table when it differs.

Why

Existing TUI skills are either framework-agnostic design notes with no Textual APIs, or Textual tutorials written for old versions (for example `Static.renderable`, `App.dark` and `Select.BLANK` were all removed or renamed). None of them ship code that has been run, and none lets the agent actually see the interface it is building.

This skill aims to fix that:

Current Textual 8.x APIs, with a break history from 0.77 to 8.x and an old-to-new map.
A design system expressed in Textual terms: layout paradigms, keyboard layers, states, color in three tiers, motion, accessibility, anti-patterns.
A performance playbook with measured numbers, not folklore.
A tested dashboard template.
A headless screenshot tool so the agent can look at its own work.

Install

Copy the skill folder into your Claude Code skills directory:

git clone https://github.com/discover-dmc/textual-healing.git
cp -R textual-healing/textual-tui ~/.claude/skills/

It activates on Textual and TUI work. No configuration needed.
