+description: "Analyzes codebase for refactoring opportunities: large files, code duplication, god classes, naming inconsistencies, tight coupling, and missing abstractions. Invoke when user asks for refactoring insight/analysis or wants to improve code architecture."
+---
+
+# Refactoring Insight
+
+Deep codebase analysis skill that identifies structural problems and produces prioritized refactoring recommendations.
+
+## When to Invoke
+
+- User asks for "refactoring insight", "refactoring analysis", "code quality analysis", "architecture review"
+- User wants to understand what should be refactored in the codebase
+- User asks "where are the code smells?" or "what needs refactoring?"
+
+## Analysis Dimensions
+
+Run all 6 dimensions in parallel where possible. For each dimension, use search agents to gather data, then synthesize findings.
+
+### 1. Large Files / God Classes
+
+- Find all .cs files over 300 lines, sorted by line count descending
+- Identify partial classes and sum their total line count across files
+- Flag classes with 15+ methods or constructors taking 8+ parameters
+- Focus on: Views/, ViewModels/, Services/, plugins/
+
+**Output**: Table of files with line counts and responsibility summary.
+
+### 2. Code Duplication
+
+Search for these specific duplication patterns:
+
+- **Service boilerplate**: Repeated DI registration, `new` instantiation instead of DI
+- **Data service pattern**: Services that fetch/parse/transform data similarly (Load → Map → Save)
+- **Localization pattern**: `private readonly LocalizationService _localizationService = new();` and `L()` helper method repetitions
+- **Helper method duplication**: Methods like `ResolveUnifiedMainRadiusValue`, `NormalizeConfig`, `ParticleState` classes copied across files
+- **Error handling pattern**: Identical try-catch blocks repeated in multiple methods
+- **Settings snapshot pattern**: `_settingsFacade.Settings.LoadSnapshot<T>(scope)` call sites
+
+**Output**: List of duplicated patterns with file locations and line numbers.
+
+### 3. Tight Coupling
+
+- Services instantiated via `new` instead of DI injection
+- ViewModels directly accessing infrastructure-layer APIs (e.g., `LoadSnapshot/SaveSnapshot`)
+- Hard-coded dependencies (GitHub repo owner/name, default values)
+- `Application.Current` upcasting to access services: `(Application.Current as App)?.SomeService`
+- Platform-specific code embedded in cross-platform services without interface abstraction
+
+**Output**: Table of coupling violations with severity (high/medium/low).
+
+### 4. Naming Inconsistencies
+
+- Service suffix inconsistency: `Service` vs `Store` vs `Helper` vs `Provider` vs `Manager` vs `Factory` for similar responsibilities
+- Model suffix inconsistency: `Snapshot` vs `State` vs `Types` for similar concepts
+- Platform prefix inconsistency: `Windows`/`Linux` full name vs `Mac` abbreviation
+- Confusing names: services with similar names but different responsibilities (e.g., `NotificationService` vs `NotificationListenerService`)
+
+**Output**: Categorized list of naming inconsistencies.
+
+### 5. Missing Abstractions
+
+- Services without corresponding interfaces (check for `I<ServiceName>` pattern)
+- Common patterns that could be extracted into base classes:
+  - `SettingsPageViewModelBase` for shared ViewModel boilerplate
+  - `JsonFileSettingsService<TSnapshot>` for repeated settings persistence
+  - `SettingsDomainServiceBase<TState>` for Load-Map-Save pattern
+  - `DesktopComponentWidgetBase` for shared Widget code
+  - `ComponentEditorViewBase` enhancements (e.g., `_suppressEvents` pattern)
+- Static singleton/Factory providers repeating thread-safe lazy-load boilerplate
+
+**Output**: List of missing abstractions with proposed base class/interface names.
+
+### 6. Misplaced Responsibilities
+
+- Files in wrong directories (e.g., data access in Settings/, UI services mixed with data services)
+- ViewModels containing business logic or file system operations
+- Widget code-behind files with excessive logic (>200 lines)
+- Platform-specific services not organized into subdirectories
+
+**Output**: List of misplaced files/classes with recommended new locations.
+
+## Output Format
+
+Produce a structured report with:
+
+1. **Summary table**: Total metrics (file count, duplication count, etc.)
+2. **Priority-ranked findings**: P0 (must fix), P1 (should fix), P2 (recommended), P3 (nice to have)
+3. **Each finding includes**: Problem description, affected files with links, specific line numbers, recommended action, estimated impact
+
+### Priority Criteria
+
+- **P0**: Files over 1000 lines with mixed responsibilities; patterns duplicated 10+ times; god classes with 20+ dependencies
+- **P1**: Patterns duplicated 5-9 times; services without interfaces that are widely used; DI bypass affecting testability
+- **P2**: Patterns duplicated 3-4 times; naming inconsistencies affecting readability; misplaced files
+- **P3**: Minor naming variations; single-instance duplications; organizational improvements
+
+## Project-Specific Context
+
+This skill is aware of the LanMountainDesktop project structure:
+
+- `LanMountainDesktop/Services/` — Business and infrastructure services
+- `LanMountainDesktop/Services/Settings/` — Settings subsystem
+- `LanMountainDesktop/ViewModels/` — View models
+- `LanMountainDesktop/Views/Components/` — Desktop widget components
+- `LanMountainDesktop/Views/ComponentEditors/` — Widget editor views
+- `LanMountainDesktop/plugins/` — Plugin runtime
+- `LanMountainDesktop.PluginSdk/` — Plugin SDK public API
+- `LanMountainDesktop.Shared.Contracts/` — Host/plugin shared contracts
+- `LanMountainDesktop.Appearance/` — Appearance and corner radius infrastructure
+
+When analyzing, respect the project's architectural boundaries documented in `docs/ARCHITECTURE.md` and `docs/ECOSYSTEM_BOUNDARIES.md`.

+# 融合桌面组件库窗口重设计规格
+
+## Why
+
+当前融合桌面组件库窗口（FusedDesktopComponentLibraryWindow）的UI设计较为基础，与Windows 11小组件编辑面板相比，缺乏现代化的交互体验和视觉层次。用户需要一个更直观、更美观的界面来浏览和添加组件到系统桌面（负一屏）。
+
+参考Windows 11小组件编辑面板的设计特点：
+
+* 左侧分类列表，右侧选中组件的详细预览
+
+* 大型组件预览区域，让用户清楚看到组件效果
+
+* 底部明显的"添加"操作按钮
+
+* 简洁的关闭按钮（X）在右上角
+
+* 深色主题配合毛玻璃效果
+
+## What Changes
+
+* **重新设计窗口布局**：从左右分栏（分类列表+组件网格）改为左侧面板+右侧预览区的布局
+
+* **添加组件详情预览区**：选中组件后右侧显示大尺寸预览和组件信息
+
+* **优化关闭按钮**：使用标准的X图标按钮，不使用圆形样式
+
+* **添加底部操作栏**：包含"添加到桌面"主操作按钮和"查找更多组件"链接
+
+* **复用阑山桌面组件库分类**：使用相同的分类ID、图标和本地化文本
+
+* **移除搜索功能**：参考Windows 11设计，暂不提供搜索
+
+## Impact
+
+* 受影响文件：
+
+  * `LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml`
+
+  * `LanMountainDesktop/Views/FusedDesktopComponentLibraryWindow.axaml.cs`
+
+  * `LanMountainDesktop/Views/FusedDesktopComponentLibraryControl.axaml`
+
+  * `LanMountainDesktop/Views/FusedDesktopComponentLibraryControl.axaml.cs`
+
+  * `LanMountainDesktop/ViewModels/ComponentLibraryWindowViewModel.cs`（可能需要添加新属性）
+
+## ADDED Requirements
+
+### Requirement: 窗口布局重设计
+
+系统应提供一个类似于Windows 11小组件编辑面板的组件库窗口。
+
+#### Scenario: 窗口整体结构
+
+* **GIVEN** 用户从托盘菜单打开融合桌面组件库
+
+* **WHEN** 窗口显示时
+
+* **THEN** 窗口应呈现：
+
+  * 顶部标题栏：左侧显示"添加小组件"标题，右侧有关闭按钮（X）
+
+  * 左侧面板：分类列表（复用阑山桌面组件库的分类和图标）
+
+  * 右侧主区域：选中组件的大尺寸预览 + 组件信息 + 添加按钮
+
+  * 底部："查找更多组件"链接
+
+#### Scenario: 分类列表交互
+
+* **GIVEN** 左侧显示组件分类列表
+
+* **WHEN** 用户点击某个分类
+
+* **THEN** 右侧应显示该分类下的第一个组件的预览
+
+* **AND** 分类项应有选中状态视觉反馈
+
+* **AND** 分类图标和名称应与阑山桌面组件库保持一致
+
+#### Scenario: 组件预览区
+
+* **GIVEN** 用户选中一个组件
+
+* **WHEN** 预览区显示时
+
+* **THEN** 应显示：
+
+  * 组件标题（大字号）
+
+  * 大尺寸组件预览图（接近实际尺寸）
+
+  * 组件描述/功能说明
+
+  * 底部"添加到桌面"按钮
+
+#### Scenario: 添加组件操作
+
+* **GIVEN** 用户查看组件预览
+
+* **WHEN** 用户点击"添加到桌面"按钮
+
+* **THEN** 组件应被添加到系统桌面（负一屏）中央
+
+* **AND** 窗口应关闭
+
+#### Scenario: 关闭按钮样式
+
+* **GIVEN** 窗口标题栏有关闭按钮
+
+* **THEN** 关闭按钮应使用标准的X图标
+
+* **AND** 不使用圆形背景或特殊样式
+
+* **AND** 使用 `DesignCornerRadiusSm` 动态资源
+
+#### Scenario: 查找更多组件链接
+
+* **GIVEN** 窗口底部显示"查找更多组件"链接
+
+* **WHEN** 用户点击该链接
+
+* **THEN** 应打开设置窗口的插件目录页面（后续将改为插件市场）
+
+## MODIFIED Requirements
+
+### Requirement: 组件列表展示
+
+原实现使用网格展示所有组件，新实现改为：
+
+* 左侧列表仅显示分类（复用阑山桌面组件库的分类ID和图标映射）
+
+* 右侧预览区一次只显示一个组件的详细信息
+
+* ~~移除搜索功能~~（根据Windows 11设计，暂不提供搜索）
+
+### Requirement: 关闭按钮圆角规范
+
+原实现关闭按钮使用硬编码 `CornerRadius="18"`，应改为使用动态资源 `DesignCornerRadiusSm`。
+
+### Requirement: 分类图标复用
+
+分类图标映射应与阑山桌面组件库保持一致：
+
+* Clock -> Symbol.Clock
+
+* Date -> Symbol.CalendarDate
+
+* Weather -> Symbol.WeatherSunny
+
+* Board -> Symbol.Edit
+
+* Media -> Symbol.Play
+
+* Info -> Symbol.Info
+
+* Calculator -> Symbol.Calculator
+
+* Study -> Symbol.Hourglass
+
+* 其他 -> Symbol.Apps
+
+## REMOVED Requirements
+
+* ~~搜索功能~~：根据Windows 11小组件面板设计，暂不提供搜索功能

 ### UI

 - 主题、资源和视觉语义优先遵守 `docs/VISUAL_SPEC.md` 与 `docs/CORNER_RADIUS_SPEC.md`
- **组件圆角**：所有内置与插件组件的根边框必须使用 `{DynamicResource DesignCornerRadiusComponent}` 资源。
+- **圆角规范 (AI 强制建议)**：
+    - **桌面组件根容器**：必须且仅能使用 `{DynamicResource DesignCornerRadiusComponent}`。
+    - **内部元素**：必须根据嵌套层级使用 `DesignCornerRadiusSm/Md/Lg` 等 Token，严禁硬编码像素值。
+    - **禁止修改系数**：严禁在圆角资源上乘以任何 `scale` 变量，圆角现在由全局样式固定控制。
 - 设置页相关改动通常同时落在 `Views/`、`ViewModels/`、`Services/` 和 `.trae/specs/`
 - UI 启动与窗口生命周期主线在 `Program.cs` 和 `App.axaml.cs`

+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version of
+       the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version of
+       the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
