The record

Purpose: Katsuragi turns UI ideas into wireframes using a text format designed for AI to read and write.
Audience: The project describes its audience as developers discussing UI with non-technical stakeholders, engineers using AI coding assistants, and teams wanting git-diffable UI specs.
CLI: Katsuragi can be run with npx or installed globally from npm as a command-line tool.
Output formats: The CLI can generate SVG, PNG, or HTML output, with SVG as the default format.
Batch conversion: The CLI supports converting multiple .kui files in one batch.
Live preview: Watch mode serves a browser preview and reloads it when the source file is saved.
Webpage conversion: The fetch command converts webpage HTML into .kui wireframes and supports desktop, mobile, and tablet viewport options.
Fetch limitation: The fetch command does not execute JavaScript, so single-page apps with client-side rendering may not work properly.
Layout limitation: The fetch command does not analyze CSS and estimates layout from document structure.
AI compatibility: The README says the plain-text .kui format works with any LLM, including ChatGPT, Claude, Gemini, and local models.
Editor integrations: The README describes workflows with Claude Code, Cursor, Aider, and other LLM-powered CLI tools.
License: The software is provided under the MIT License.
Runtime requirement: The package specifies Node.js version 18.0.0 or later.
Maintainer: The package lists En-Links LLC as its author.
