Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
This standard governs the modernization of legacy code and the surgical decomposition of high-complexity monolithic structures.Key capabilities
- →Decompose monolithic services into triad layers
- →Convert mutable POJOs to Java Records
- →Enforce package-private visibility for controllers
- →Validate logic preservation via Gradle
How it works
The skill applies a Clean Chain strategy to separate concerns by splitting monolithic classes into controllers, service interfaces, and repositories while enforcing immutability with Java Records.
Inputs & outputs
When to use refactor
- →Decompose a monolithic service
- →Refactor legacy classes to Java Records
- →Apply single responsibility principle
- →Clean up service visibility
About refactor
Applies refactoring patterns to split monolithic services into separate business logic, data access, and model layers, focusing on immutability and concern separation.
This standard governs the modernization of legacy code and the surgical decomposition of high-complexity monolithic structures.
When not to use it
- →Refactoring for lean or minimum viable intent
- →Services where business logic and data access are already separated
Prerequisites
Limitations
- →Service handling business logic and data access must be split
How it compares
It mandates surgical decomposition into a specific service triad rather than generic code cleanup.
