+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+---
+
+# Android Accessibility Checklist
+
+## Instructions
+
+Analyze the provided component or screen for the following accessibility aspects.
+
+### 1. Content Descriptions
+*   **Check**: Do `Image` and `Icon` composables have a meaningful `contentDescription`?
+*   **Decorative**: If an image is purely decorative, use `contentDescription = null`.
+*   **Actionable**: If an element is clickable, the description should describe the *action* (e.g., "Play music"), not the icon (e.g., "Triangle").
+
+### 2. Touch Target Size
+*   **Standard**: Minimum **48x48dp** for all interactive elements.
+*   **Fix**: Use `MinTouchTargetSize` or wrap in `Box` with appropriate padding if the visual icon is smaller.
+
+### 3. Color Contrast
+*   **Standard**: WCAG AA requires **4.5:1** for normal text and **3.0:1** for large text/icons.
+*   **Tool**: Verify colors against backgrounds using contrast logic.
+
+### 4. Focus & Semantics
+*   **Focus Order**: Ensure keyboard/screen-reader focus moves logically (e.g., Top-Start to Bottom-End).
+*   **Grouping**: Use `Modifier.semantics(mergeDescendants = true)` for complex items (like a row with text and icon) so they are announced as a single item.
+*   **State descriptions**: Use `stateDescription` to describe custom states (e.g., "Selected", "Checked") if standard semantics aren't enough.
+
+### 5. Headings
+*   **Traversal**: Mark title texts with `Modifier.semantics { heading() }` to allow screen reader users to jump between sections.
+
+## Example Prompts for Agent Usage
+*   "Analyze the content description of this Image. Is it appropriate?"
+*   "Check if the touch target size of this button is at least 48dp."
+*   "Does this custom toggle button report its 'Checked' state to TalkBack?"

+description: Expert guidance on setting up and maintaining a modern Android application architecture using Clean Architecture and Hilt. Use this when asked about project structure, module setup, or dependency injection.
+---
+
+# Android Modern Architecture & Modularization
+
+## Instructions
+
+When designing or refactoring an Android application, adhere to the **Guide to App Architecture** and **Clean Architecture** principles.
+
+### 1. High-Level Layers
+Structure the application into three primary layers. Dependencies must strictly flow **inwards** (or downwards) to the core logic.
+
+*   **UI Layer (Presentation)**:
+    *   **Responsibility**: Displaying data and handling user interactions.
+    *   **Components**: Activities, Fragments, Composables, ViewModels.
+    *   **Dependencies**: Depends on the Domain Layer (or Data Layer if simple). **Never** depends on the Data Layer implementation details directly.
+*   **Domain Layer (Business Logic) [Optional but Recommended]**:
+    *   **Responsibility**: Encapsulating complex business rules and reuse.
+    *   **Components**: Use Cases (e.g., `GetLatestNewsUseCase`), Domain Models (pure Kotlin data classes).
+    *   **Pure Kotlin**: Must NOT contain any Android framework dependencies (no `android.*` imports).
+    *   **Dependencies**: Depends on Repository Interfaces.
+*   **Data Layer**:
+    *   **Responsibility**: Managing application data (fetching, caching, saving).
+    *   **Components**: Repositories (implementations), Data Sources (Retrofit APIs, Room DAOs).
+    *   **Dependencies**: Depends only on external sources and libraries.
+
+### 2. Dependency Injection with Hilt
+Use **Hilt** for all dependency injection.
+
+*   **@HiltAndroidApp**: Annotate the `Application` class.
+*   **@AndroidEntryPoint**: Annotate Activities and Fragments.
+*   **@HiltViewModel**: Annotate ViewModels; use standard `constructor` injection.
+*   **Modules**:
+    *   Use `@Module` and `@InstallIn(SingletonComponent::class)` for app-wide singletons (e.g., Network, Database).
+    *   Use `@Binds` in an abstract class to bind interface implementations (cleaner than `@Provides`).
+
+### 3. Modularization Strategy
+For production apps, use a multi-module strategy to improve build times and separation of concerns.
+
+*   **:app**: The main entry point, connects features.
+*   **:core:model**: Shared domain models (Pure Kotlin).
+*   **:core:data**: Repositories, Data Sources, Database, Network.
+*   **:core:domain**: Use Cases and Repository Interfaces.
+*   **:core:ui**: Shared Composables, Theme, Resources.
+*   **:feature:[name]**: Standalone feature modules containing their own UI and ViewModels. Depends on `:core:domain` and `:core:ui`.
+
+### 4. Checklist for implementation
+- [ ] Ensure `Domain` layer has no Android dependencies.
+- [ ] Repositories should default to main-safe suspend functions (use `Dispatchers.IO` internally if needed).
+- [ ] ViewModels should interact with the UI layer via `StateFlow` (see `android-viewmodel` skill).
