# Spring Kotlin Clean Code Convention

Apply the following principles when writing or refactoring Spring + Kotlin code.
Load the relevant reference files and follow their guidelines.

## Principles

| # | Area | Reference |
|---|------|-----------|
| 1 | Naming conventions | `references/naming.md` |
| 2 | Readability (newspaper structure) | `references/readability.md` |
| 3 | Error handling | `references/error-handling.md` |
| 4 | SOLID principles | `references/solid.md` |
| 5 | Kotlin idioms | `references/kotlin-idioms.md` |
| 6 | Spring layer rules & DTO naming | `references/spring-layers.md` |

Load all 6 reference files when writing or refactoring code from scratch.
Load only the relevant ones for targeted questions (e.g., user asks only about naming → load `references/naming.md`).
