SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill automates turning Unity UI layout detection JSON into fully wired GameObjects and prefabs, eliminating manual setup.

Core Features & Use Cases

  • Automate UI prefab generation from detection JSON using MCP tool calls.
  • Enforce project conventions and localization wiring while building the hierarchy.
  • Create ready-to-use UI prefabs for screens like popups, menus, and dashboards, including missing assets handling with placeholders.

Quick Start

Provide the detection JSON to the build-ui workflow and specify the target prefab path to generate the Unity UI prefab.

FAQPage Schema
How do I convert detection JSON into a Unity UI prefab?▼

To convert detection JSON into a Unity UI prefab, you provide the JSON and a target path to the build workflow, which then orchestrates MCP tool calls to create GameObjects, configure RectTransforms, and output the prefab automatically.

Does Unity UI prefab generation from detection JSON handle missing assets?▼

Yes, Unity UI prefab generation from detection JSON handles missing assets by substituting placeholders, ensuring the hierarchy remains intact while enforcing project conventions during the MCP tool call sequence.

Can I automate Unity UI hierarchy creation for popups and dashboards using MCP?▼

Yes, you can automate Unity UI hierarchy creation for popups, menus, and dashboards using MCP tool calls to set parents and add components directly from detection JSON data.

How does detection JSON define RectTransforms and components for Unity UI?▼

Detection JSON defines RectTransforms and components for Unity UI by specifying rects, components, assets, and hierarchy within the JSON structure, which the build workflow reads to configure GameObjects accordingly.

What is the best way to enforce project conventions when building Unity UI prefabs?▼

The best way to enforce project conventions when building Unity UI prefabs is to use an automated MCP workflow that applies build-rules, including localization wiring and asset handling, during GameObject creation from detection JSON.

Do I need unity-ui-analyzer detection JSON to use build-ui?▼

Yes, you need unity-ui-analyzer detection JSON because build-ui is designed to process the specific JSON output defining rects and hierarchy from that analyzer to generate Unity UI prefabs.
