# Add Repository Skill

## Overview & Prerequisites

This skill guides you to implement/update an use case in spark component.

## Component Selection

**Parameter Handling:**
- If the skill is invoked with a parameter (e.g., `/spark-component-use-case button`):
  - Use the parameter as the component name
  - Verify the folder exists in `Modules/Components/{component-name}/`
  - If found, use that component and skip the selection step

- If no parameter is provided:
  - List all folders in the `Modules/Components/` directory
  - Use AskUserQuestion to let the user select ONE component from the list
  - Format: Display folder names as options (e.g., "button", "card", "checkbox")

**Once the component is selected, all operations must be performed in `Modules/Components/{component-name}/` folder.**

Use the files in the **template** folder as reference to manage the *use case* and the *unit tests*.

## Rules

The UseCase file must respect theses rules : 
  - must be located in *Sources/Core/ViewModel* and in *Tests/UnitTests/ViewModel*.
  - should contains `procotol` and a ``struct`` implementation.
  - should have only one ``func execute`` except if I ask to have other func.
  - should have this comment before the protocol ```// sourcery: AutoMockable, AutoMockTest```
  - if the parameter contains a theme, add before the func ```// sourcery: theme = "Identical"```

## Workflow
  - [ ] Add/Update the code.
  - [ ] Add/Update the documentation if the use case is public.
  - [ ] Run swiftlint ```$ swiftlint```.
  - [ ] Run sourcery ```$ sourcery```
  - [ ] Implement the unit tests. Read theses folders to get mocks :
    - *spark-ios-component-XXX/Sources/Testing*
    - *spark-ios-common/Sources/Testing*
    - *spark-ios-theming/Sources/Testing*

### Code Conventions
- [ ] File headers follow pattern: `Created by {firstname.lastname} on DD/MM/YYYY`
- [ ] Copyright line includes current year
- [ ] No empty lines contain whitespace or tabs
- [ ] All class members accessed with `self.`
- [ ] Protocol marked with `// sourcery: AutoMockable`
- [ ] Proper MARK comments in place

### Test Implementation
- [ ] Tests must be written in **Swift Testing** framework
- [ ] Proper imports (SparkComponentXXX, SparkCommon, SparkTheming, @testable, @_spi(SI_SPI) @testable import SparkComponentXXXTesting, Testing, ...)
