> **Before calling any skill in this module:** if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via `GET /skills/recommend?includeSchema=true`) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Building UGUI screens
• Adding Canvas elements
• Arranging UI layout
• 搭建 UGUI 界面、添加 Canvas 元素、排布 UI 布局

Unity UI Skills

Use this module for Unity UGUI / Canvas workflows. It is separate from UI Toolkit.

> **Batch-first**: Prefer `ui_create_batch` when creating `2+` UI elements.

Operating Mode

• **Approval**：查询类 skill（`ui_find_all`，源码标 `SkillMode.SemiAuto`）直接执行；其余创建/修改类（`ui_create_*` / `ui_set_*` / `ui_add_*` / `ui_layout_children` / `ui_align_selected` 等，标 `SkillMode.FullAuto`）需用户 grant，grant 后服务端一步执行返结果。
• **Auto / Bypass**：所有 skill 直接执行；Auto 走 AI 自我评估，Bypass 全放行。
• 本模块**不含** Delete / PlayMode / Reload / 高危 skill，无 Bypass-only 拦截项。删除 UI 节点请走 `gameobject` 模块。

**DO NOT** (common hallucinations):

• `ui_add_canvas` does not exist -> use `ui_create_canvas`
• `ui_create_label` does not exist -> use `ui_create_text`
• `ui_create_checkbox` does not exist -> use `ui_create_toggle`
• `ui_set_color` does not exist -> use `component_set_property` on `Image`/`Text`, or the dedicated UI property skills when available
• Do not confuse UGUI (`ui`) with UI Toolkit (`uitoolkit`)

**Routing**:

• For UXML/USS/UIDocument -> use `uitoolkit`
• For XR-compatible world-space Canvas conversion -> use `xr_setup_ui_canvas`
• For text updates after creation -> use `ui_set_text`
• For layout and alignment -> use `ui_layout_children`, `ui_align_selected`, `ui_distribute_selected`

High-Frequency Defaults

Canvas and Parenting

• `ui_create_canvas` defaults to `ScreenSpaceOverlay`.
• Most create skills accept `parent`; if omitted, Unity will create under the active Canvas or scene root depending on the implementation context.
• For reusable menu groups, create the Canvas once, then create a Panel and put all child controls under that panel.

Common Create Parameters

| Skill | High-frequency fields | |-------|-----------------------| | `ui_create_button` | `text`, `width`, `height` | | `ui_create_text` | `text`, `fontSize`, `r/g/b` | | `ui_create_image` | `spritePath`, `width`, `height` | | `ui_create_slider` | `minValue`, `maxValue`, `value` | | `ui_create_toggle` | `label`, `isOn` | | `ui_create_dropdown` | `options` | | `ui_create_scrollview` | `horizontal`, `vertical`, `movementType` |

Important:

• Most create skills do **not** take explicit `x/y` placement.
• Create first, then place/anchor with `ui_set_rect`, `ui_set_anchor`, or `ui_layout_children`.

Full RectTransform Editing

Use `ui_set_rect_transform` when you need Inspector-level RectTransform coverage instead of a preset.

| Skill | Parameters | |-------|------------| | `ui_get_rect_transform` | `name`, `instanceId`, `path` | | `
