What it does

Kotlin Android is an agent skill from WrongStack/WrongStack. Build and upgrade native Android applications with Kotlin, Compose/View UI and lifecycle-aware work. Use when implementing Android screens, navigation, permissions or background jobs; coordinate Kotlin, Gradle, AGP and SDK compatibility.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Android development. It works with Android, Kotlin and Gradle. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.

When your agent uses it

  • Implementing Android screens
  • Background jobs
  • Coordinate Kotlin
  • AGP and SDK compatibility

Example prompts

  • “/kotlin-android”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inspect build plugins/catalogs, SDK levels, app id, manifests and signing variants.
  2. Scope coroutines/flows to the correct lifecycle and use structured cancellation.
  3. Keep UI state observable and ownership explicit; recomposition is not permission to start duplicate side effects.
  4. Handle permission denial, process recreation, background restrictions and saved state as real product states.
  5. Match Android back/navigation, insets, large screens and accessibility.
  6. Store sensitive app credentials in supported mechanisms and authorize data operations on the server.

What it can do on your machine

Read from SKILL.md and the folder at commit a744bdc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • developer.android.com
    • github.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kotlin Android loads about 824 tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 293 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~63
When it runs · the whole SKILL.md, loaded when a task matches
~824

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Kotlin Android

Selection card

  • Task: Build Kotlin Android and Jetpack Compose features. / TR: Kotlin Android ve Jetpack Compose özellikleri kur.
  • Start: Identify the platform, screen, device and native integration boundary.
  • Finish: apply the acceptance checks below; report observed results and unresolved constraints.

Overview

Build and upgrade native Android applications with Kotlin, Compose/View UI and lifecycle-aware work.

Checked 2026-10-09: Kotlin 2.4.21 and Gradle 9.8.1. Verify current AGP/Compose/compiler/JDK and Android SDK matrix; independently latest versions may not form a supported build.

Rules

  1. Inspect build plugins/catalogs, SDK levels, app id, manifests and signing variants.
  2. Scope coroutines/flows to the correct lifecycle and use structured cancellation.
  3. Keep UI state observable and ownership explicit; recomposition is not permission to start duplicate side effects.
  4. Handle permission denial, process recreation, background restrictions and saved state as real product states.
  5. Match Android back/navigation, insets, large screens and accessibility.
  6. Store sensitive app credentials in supported mechanisms and authorize data operations on the server.

Workflow

  1. Trace screen/ViewModel/repository and current UI/data conventions.
  2. Verify the stable supported build-tool/SDK combination and migration steps.
  3. Implement lifecycle-owned work and visible states.
  4. Test process/lifecycle transitions, navigation, permissions and window sizes.
  5. Run configured lint/tests/build and verify the app on a representative device.

Before returning

Tool/SDK matrix clear; coroutine/state lifecycle checked; device behavior and signing/release proof separated.

Sources

Versioned facts checked 2026-10-09; refresh authoritative sources before new installs/upgrades. Kotlin releases, Android architecture, Android build.

Skills in scope

  • mobile-design — design and implement mobile interfaces for touch, keyboards, safe areas and native navigation.
  • mobile-performance — measure and improve mobile startup, scrolling, animation and resource usage on representative devices.
  • mobile-release — prepare and verify signed mobile releases, test-channel distribution and store submission artifacts.
  • offline-sync — implement offline-capable applications with local persistence, queued changes and explicit synchronization conflicts.
