## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3628, "days_push": 813, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A curated collection of classic Gang of Four design patterns (behavioral, creational, structural) implemented as idiomatic Kotlin code examples. It serves as a reference for learning how design patterns translate into Kotlin's language features.

## Use cases
- learn design patterns in kotlin
- see observer pattern implemented in kotlin
- kotlin examples of creational and structural patterns
- study idiomatic kotlin for software design
- reference for design patterns on android with kotlin
- compare design patterns across languages

## When to choose
- you want concise, runnable Kotlin examples of classic design patterns
- you are learning Kotlin and already know pattern concepts from other languages
- you need a quick reference for pattern implementations on the JVM or Android

## When to avoid
- you need a production-ready pattern library to import as a dependency
- you want comprehensive coverage of all patterns or modern architectural patterns
- you need a tutorial with step-by-step explanations rather than code examples

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools, documentation
- domain: programming-languages, tutorials, developer-tools
- platform: jvm
- tags: design-patterns, kotlin, educational, code-examples, software-architecture, android
