What Kotlin does

Kotlin designs, implements, and reviews Kotlin and Android APIs for .kt files, nullability, sealed types, coroutines, threading, Java interop, and Kotlin-backed React Native Nitro Modules.

Kotlin is cataloged under AI Engineering on DirSkills. Kotlin comes from a repository tagged agent, agent-skills, ai, llm and react.

Documentation

README

Excerpt

Kotlin

Use this skill for Kotlin code that needs strong type modeling, explicit async boundaries, and idiomatic Android integration. When the code is part of a Nitro Module, pair this with build-nitro-modules for generated specs, Promise mapping, annotations, and HybridObject constraints.

Workflow

Read the local Kotlin code, generated abstract classes, and public API shape before editing.
Model valid states with Kotlin types before implementing behavior.
Choose whether work is synchronous, coroutine-based, or explicitly dispatched.
Keep properties cheap and nonblocking.
Make thread hops, Android service access, I/O, and fallible work visible in the API.

This is the opening of the README. Read the full README on GitHub.

Frequently asked about Kotlin

What else does margelo publish alongside Kotlin?
Kotlin is one of 9 skills that DirSkills catalogs from margelo/react-native-skills, the repository it ships in. Its siblings there include API Design, Build Nitro Modules and C++. Each one is a separate skill with its own page in this directory, installs the same way Kotlin does, and is maintained by margelo in that same repository. The rest of the collection is listed on the margelo/react-native-skills page.
How does Kotlin compare to other AI Engineering skills?
Kotlin ranks #3310 by stars among the 3670 AI Engineering skills in this catalog. The most-starred ones next to it are Architecture Decision Records, AI-First Engineering and Agentic OS. DirSkills ranks by the star count of the repository each skill ships in, so that order reflects how popular those repositories are rather than any review of Kotlin against them. Open each page to compare what they document and how they install.
