## **Commit Message Rules**

1. **Subject Line:**
   - Format: `type(scope): subject`
   - Use present tense (e.g., "Add feature", not "Added feature").
   - Keep it concise (72 characters or fewer).
   - Avoid ending with a period.
   - Example: `feat(python): add new testing pipeline`.

2. **Body:**
   - Must be separated from the subject by a blank line.
   - Explain _what_ and _why_, not _how_.
   - Use bullet points for multiple items.
   - Example:
     ```
     feat(python): add new testing pipeline

     - Added comprehensive tests with coverage reporting
     - Integrated with popular testing frameworks
     - Enhanced reporting for detailed metrics
     ```

3. **Breaking Changes:**
   - Add `!` after the type/scope: `feat(python)!: change API structure`.
   - Include a `BREAKING CHANGE:` section in the footer.
   - Example:
     ```
     feat(python)!: update testing API structure

     BREAKING CHANGE: The test runner now requires explicit configuration.
     ```

## **Module Naming and Structure**

1. **Module Import Path**
   - Modules must follow this structure:  
     ```
     github.com/felipepimentel/daggerverse/<pasta>/<module_name>/internal/dagger
     ```

2. **Directory Responsibilities**
   - **`internal/`**: Contains auto-generated files. **Do not manually modify files here**.
   - **`dagger.gen.go`**: An auto-generated file. Any updates must be done using:
     ```bash
     dagger develop
     ```

3. **Protected Components**
   - Changes to `dagger.gen.go` or files in `/internal` are prohibited.
   - Validate generated content with the `dagger develop` command.

4. **Example Module Structure**
   ```
   daggerverse/
   ├── python/
   │   ├── pipeline/
   │   │   ├── go.mod
   │   │   ├── main.go
   │   │   └── internal/
   │   │       └── dagger/
   │   │           ├── dagger.gen.go
   │   │           └── (other auto-generated files)
   ├── nodejs/
   │   ├── scheduler/
   └── global/
   ```

## **Reusing Internal Modules**

### **1. Declaring Module Dependencies**

To reuse an internal module, declare it as a dependency in your module’s `dagger.json` file. This ensures the dependency is linked during the development process.

Example `dagger.json`:
```json
{
  "name": "wolfi",
  "engineVersion": "v0.15.2",
  "sdk": "go",
  "dependencies": [
    {
      "name": "apko",
      "source": "../apko"
    }
  ],
  "source": "."
}
```

### **2. Using Internal Modules**

After declaring the dependency in `dagger.json`, you can access the module’s exported structures or methods by importing it into your Go code. For example:

```go
package main

import (
	"github.com/felipepimentel/daggerverse/essentials/wolfi/internal/dagger"
)

// A Dagger Module to integrate with Wolfi Linux
type Wolfi struct{}

// Build a Wolfi Linux container
func (w *Wolfi) Container(
	// APK packages to install
	// +optional
	packages []string,
	// Overlay images to merge on top of the base.
	// +optional
	overlays []*dagger.Container,
) *dagger.Container {
	ctr := dag.Apko().Wolfi(packages)
	for _, overlay := range overlays {
		ctr = ctr.WithDirectory("/", overlay.Rootfs())
	}
	return ctr
}
```

In this example:
- The `dag.Apko()` function refers to the `apko` dependency declared in `dagger.json`.
- Dependencies are structured to encourage code reuse and modularity.

### **3. Guidelines for Reusing Modules**

- **Always declare dependencies** in `dagger.json` to make them explicit and trackable.
- **Avoid duplicating logic**; reuse existing modules when functionality overlaps.
- **Leverage internal APIs**: Use exported functions or methods provided by the dependent module.
- **Document dependencies** in the README or inline comments to clarify module relationships.

## **Code Quality Rules**

1. **General**
   - Adhere to idiomatic Go practices.
   - Ensure all changes pass linting and formatting checks.
   - Write unit tests for all new or modified functionality.

2. **Dagger Workflow-Specific Rules**
   - Always use `dagger/<module>/internal/dagger` for imports.
   - Validate Dagger and Go versions:
     - Dagger version: `0.15.2`.
     - Go version: `1.23.2`.

3. **Testing**
   - Mock external dependencies where possible.
   - Ensure CI/CD workflows test all critical paths.

4. **Documentation**
   - Clearly describe module purpose and usage.
   - Highlight any requirements for Dagger or Go versions.

## **Breaking Changes**

1. **Commit Header:**
   - Use `!` after `type(scope)` (e.g., `feat(python)!:`).

2. **Commit Footer:**
   - Include a `BREAKING CHANGE:` section explaining the impact and migration steps.
