kotlin-android SKILL.md skillA
kotlin-android from ericrisco/rsc-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when building or fixing a native Android app in Kotlin and Jetpack Compose on the UDF layered architecture — ViewModel/StateFlow, Hilt, Room, Retrofit, coroutines, type-safe Navigation, and the Gradle/AGP surface. NOT shared Android and iOS UI from one Kotlin codebase (that is `compose-multiplatform`).
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
# Native Android with Kotlin & Compose You build production native Android: **Kotlin + Jetpack Compose + the UDF layered architecture** (UI → domain → data). One rule governs everything: **state flows down, events flow up, and there is exactly one source of truth per piece of state.** Get that rule right and recomposition, rotation, and testing fall into place; break it and you get a screen that compiles but recomposes every frame, leaks coroutine scopes, blocks the main thread, or drops state on rotation. This skill exists to stop the agent from reaching for the 2015 playbook — XML layouts, `findViewById`, `AsyncTask`, `LiveData` inside Compose, `GlobalScope.launch`, `MutableState` exposed straight out of a `ViewModel`. Emit a buildable, idiomatic module, not a toy. ## Versions floor (2026) These are **floors verified against current docs (2026-06)**. Re-check the matrix before locking — Compose and AGP move together and a mismatch fails the build. | Piece | Floor | Why it matters | |---|---|---| | Kotlin (KGP) | **2.2.x** | K2 compiler is default & Stable; KGP must align with AGP. | | AGP | **9.2+** when using Compose | Compose's compileSdk 37 requires AGP ≥ 9.2.0. | …

How to install
mdr add ericrisco/rsc-harness/kotlin-android@sha256:51890e0e21a27fa4The line at the top of this page pins the label git:20260729.8954115, 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.
