Serialization Safety (Grade A)Security-tested data-ai skill for Claude AI. Grade A. Unity serialization rules — FormerlySerializedAs on renames, SerializeField vs public, SerializeReference for polymorphism, Unity null check (== n

Serialization Safety is a security-tested data-AI skill for Claude AI, focusing on Unity serialization rules to prevent silent data loss. It ensures that all configured values in scenes, prefabs, and ScriptableObjects are properly serialized and deserialized, avoiding resets to default values without warning. The skill emphasizes the importance of following specific rules to maintain data integrity. Rule 1 highlights the need to use the FormerlySerializedAs attribute when renaming fields to prevent breaking the name-value mapping. Rule 2 explains the difference between Unity's null check and C#'s null check, emphasizing the importance of using Unity's null check to detect destroyed objects. The skill also outlines what Unity serializes, including public fields, SerializeField private and protected fields, and certain types such as int, float, and string. It notes that properties, static fields, readonly fields, and const fields are not serialized. Additionally, it discusses the use of SerializeReference for polymorphism and NonSerialized for cached data. By following these rules, developers can ensure that their data is properly serialized and deserialized, preventing silent data loss and maintaining the integrity of their applications. The skill is particularly important for Unity developers, as it helps them to avoid common pitfalls and ensure that their applications function as intended. Overall, Serialization Safety is a critical skill for any Unity developer, as it provides a foundation for building robust and reliable applications. By understanding and following the rules outlined in this skill, developers can write more effective and efficient code, and avoid common errors that can lead to data loss and other issues. The skill is designed to work with Claude AI, providing a security-tested data-AI solution for Unity developers. By leveraging this skill, developers can improve the overall quality and reliability of their applications, and ensure that their data is properly serialized and deserialized.
