programming-kotlin from muvon/octomind-tap is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add muvon/octomind-tap/programming-kotlin@git:20261013.a69e0bbPins git:20261013.a69e0bb in mdr.lock. Pin the fingerprint instead.

Idiomatic Kotlin best practices for AI coding agents: null-safety, coroutine ownership, Flow delivery, and Android/Multiplatform boundaries. Auto-activates in Kotlin projects.
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
## Overview Use for Kotlin implementation and review across JVM, Android, and Multiplatform projects. Prefer concise expressions with visible ownership and failure semantics; preserve the repository's architecture and toolchain constraints. ## Mental model Nullability describes absence, immutability describes ownership, and coroutine scopes describe lifetime. These are separate contracts: `val`, `List`, and `suspend` do not by themselves guarantee immutable data, thread safety, or background execution. ## Version gate As of 2026-10: Kotlin 2.4 is the stable language line (2.4.21 at research time; 2.5.0 planned for December 2026). It stabilizes context parameters, explicit backing fields, the `@all` meta-target, and new use-site annotation defaulting rules. Explicit context arguments, collection literals, and improved compile-time constants remain experimental behind compiler flags. Check the actual compiler, language/API version, Gradle plugin, JVM target, and platform compatibility before using new syntax. …

How to install
mdr add muvon/octomind-tap/programming-kotlin@sha256:563720e622cee29bThe line at the top of this page pins the label git:20261013.a69e0bb, 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.
