kotlin-patterns SKILL.md skillA
kotlin-patterns from affaan-m/ecc is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add affaan-m/ecc/kotlin-patterns@git:20260607.ac0f11cPins git:20260607.ac0f11c in mdr.lock. Pin the fingerprint instead.

Patrones idiomáticos de Kotlin, buenas prácticas y convenciones para construir aplicaciones Kotlin robustas, eficientes y mantenibles con coroutines, null safety y builders de DSL.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Patrones de Desarrollo Kotlin
Patrones idiomáticos de Kotlin y buenas prácticas para construir aplicaciones robustas, eficientes y mantenibles.
## Cuándo Usar
- Escribir nuevo código Kotlin
- Revisar código Kotlin
- Refactorizar código Kotlin existente
- Diseñar módulos o librerías Kotlin
- Configurar builds con Gradle Kotlin DSL
## Cómo Funciona
Este skill aplica convenciones idiomáticas de Kotlin en siete áreas clave: null safety usando el sistema de tipos y operadores de llamada segura, inmutabilidad mediante `val` y `copy()` en data classes, clases selladas e interfaces para jerarquías de tipos exhaustivas, concurrencia estructurada con coroutines y `Flow`, funciones de extensión para agregar comportamiento sin herencia, builders de DSL type-safe usando `@DslMarker` y receptores lambda, y Gradle Kotlin DSL para configuración de build.
## Ejemplos
**Null safety con el operador Elvis:**
```kotlin
fun getUserEmail(userId: String): String {
val user = userRepository.findById(userId)
return user?.email ?: "unknown@example.com"
}
```
**Sealed class para resultados exhaustivos:**
```kotlin
sealed class Result<out T> {

How to install
mdr add affaan-m/ecc/kotlin-patterns@sha256:f2846750eb9d8da0The line at the top of this page pins the label git:20260607.ac0f11c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
