To generate Kotlin data classes from a JSON string, the Skill parses the JSON, infers types like String, Int, Long, Double, Boolean, and List<T>, and outputs @Serializable data classes with non-nullable val properties.

kotlinx serialization handles JSON keys with underscores by applying @SerialName annotations to the properties while maintaining standard camelCase naming conventions for the Kotlin data class fields.

Yes, you can create Kotlin DTOs for nested JSON objects. The generation process automatically maps nested JSON objects into separate top-level @Serializable data classes within the same Kotlin file.

The best way to convert a large JSON payload into serializable Kotlin code is using a code generator that automatically infers Long for integers exceeding Int range and enforces non-nullable val properties to prevent null reference errors.

Generating Kotlin DTOs requires a standard Kotlin project structure. The tool infers the target package by reading src/main/kotlin/Main.kt and automatically writes the generated data classes to the src/main/kotlin directory.

Integer JSON values are mapped to Long instead of Int in generated Kotlin DTOs when the integer values exceed the standard Int range, ensuring data integrity and preventing integer overflow during serialization.
