description	Unity UI guidance for UGUI and UI Toolkit. Use when creating, reviewing, or optimizing UI in a target Unity project through MCP tools or source edits.

Unity UI

Use This Skill When

• Creating or modifying UGUI or UI Toolkit.
• Reviewing Canvas hierarchy, event system, layout groups, anchors, or UI performance.
• Using MCP UI tools in a target project.

Rules

• Check whether the target project uses UGUI, UI Toolkit, or both.
• Match the existing UI system and hierarchy.
• Keep layout explicit and inspectable.
• Avoid nested layout groups and ContentSizeFitter chains unless needed.
• Split canvases by update frequency when performance requires it.
• Do not add UI packages or frameworks without explicit need.
• Do not use switch.

Verification

• Inspect hierarchy after changes.
• Check anchors, scaling, and safe-area behavior when relevant.
• Check console errors.
• For user-facing UI, verify at representative aspect ratios.
