Unity UI Toolkit Skills

Use this module for Unity UI Toolkit only: UXML for structure, USS for styling, UIDocument for scene attachment, and PanelSettings for runtime rendering.

Requires Unity 2022.3+. Do not mix this module with ui_* UGUI/Canvas skills. Localization: Match visible UI text to the user's language. Chinese conversation -> Chinese labels/placeholders/button text. USS class names and CSS variables stay English.

Operating Mode

• Approval：查询类 skill（uitk_read_file / uitk_find_files / uitk_get_panel_settings / uitk_list_documents / uitk_inspect_uxml / uitk_list_uss_variables / uitk_inspect_document，源码标 SkillMode.SemiAuto）直接执行；其余文件/场景写入类（uitk_create_* / uitk_write_file / uitk_add_* / uitk_modify_element 等，标 SkillMode.FullAuto）需用户 grant，grant 后服务端一步执行返结果。
• Auto / Bypass：未被禁列表拦截的 skill 直接执行。
• 本模块含 Delete 类 skill：uitk_delete_file、uitk_remove_element、uitk_remove_uss_rule 标记为 SkillOperation.Delete，被 IsForbiddenInSemi 静态拦截 —— 仅 Bypass 模式或加入 Allowlist 才能调用。
• Asset 重导行为：所有写文件/删文件 skill 通过 AssetDatabase.ImportAsset(path) 对单个 USS/UXML 资产单独触发导入，不会调 AssetDatabase.Refresh() 触发全项目扫描；批量创建依次单独 Import。但 USS/UXML 是 ScriptedImporter 类型，Import 仍会重建依赖此资产的 PanelSettings/UIDocument 引用，触发 IMGUI 检查器刷新与场景视图重绘。
