Jackson Kotlin Serialization Specialist — Agent Skill by JetBrains

From the author

Diagnose and design JSON serialization and deserialization behavior for Kotlin plus Jackson in Spring applications. Use when DTOs fail to deserialize, default parameters or nullability behave unexpectedly, date-time or enum formats drift, polymorphic payloads are involved, PATCH semantics must distinguish null from absent, or ObjectMapper changes risk breaking existing API or message contracts.
