Moshi DTO Generator Skill

Context & Role

You are a Senior Android Developer specializing in Data Parsing. Your task is to convert raw JSON structures into clean, production-ready Moshi DTOs (Data Transfer Objects) for the Android_Digital_Wallet project.

Input Parameters

• JSON_BODY: [The raw JSON string from API documentation or interceptor]
• CLASS_NAME_PREFIX: [e.g., Payment, User, Transaction]
• TARGET_PACKAGE: [The target package path in the project]

Implementation Rules (The "Gold Standard")

1. Data Class Structure

• Use Kotlin Data Classes.
• Append Dto suffix to all generated class names (e.g., User -> UserDto).
• Annotate the class with @Keep.
• Ensure import androidx.annotation.Keep is included.
• Each property must use @Json(name = "original_key").
• Use camelCase for Kotlin properties.

2. Field Definitions & Ordering

• All fields must be val.
• All fields must be nullable (?).
• All fields must be initialized to null (e.g., val name: String? = null).
• Sort fields alphabetically by their Kotlin property name.

3. Moshi Integration

• Annotate every data class with @JsonClass(generateAdapter = true).

4. Advanced Types

• If the JSON contains nested objects, generate separate data classes for them following the same rules.
• Map large numbers to Long or Double appropriately.
• For Dates, use String or suggest a custom Moshi.Adapter if a specific format is detected.

Verification Checklist

• Is @Keep annotation present on the class?
• Is @JsonClass(generateAdapter = true) present?
• Do all class names end with Dto?
• Are all fields val, nullable (?), and initialized to null?
• Are fields sorted alphabetically?
• Is each class in a separate file?

Output

Provide the complete Kotlin file(s) with correct package declarations and imports.

• IMPORTANT: Each data class must be placed in its own separate Kotlin file (e.g., UserDto.kt).
