Android Development Guidelines

A ruleset that guides Claude to write Kotlin Android code using clean architecture, MVI, and Material 3 conventions.

Dev & CodingIntermediate★ 272⑂ 42AI score 6/10Last updated: Oct 8, 2026

What it does

  • Enforces Kotlin conventions: naming rules, function/class size limits, immutability, SOLID.
  • Proposes a four-layer clean architecture (data / domain / presentation / di) with Repository and Use Case separation.
  • Guides MVI design: a single immutable state object and one entry point for user intents.
  • Collects UI-layer conventions: Navigation Component, ViewBinding, ConstraintLayout, Material 3, responsive layouts.
  • Covers Coroutines/WorkManager, Hilt/Dagger DI, Espresso testing, and performance tips like RecyclerView DiffUtil.

Who it's for

  • Android developers writing Kotlin, solo or on small teams.
  • Projects without an agreed code-review standard or convention doc.
  • Codebases that still use XML layouts and Fragments rather than Jetpack Compose.

Usage examples

  1. "Write the login screen ViewModel using MVI" → generates a single state class, intent entry point, and Flow-based state exposure.
  2. "Review this Repository class" → flags magic numbers, oversized functions, and non-idiomatic exception handling.
  3. "Scaffold the folder structure for a new app" → suggests data/domain/presentation/di layers plus Hilt module placement.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the android-development folder from the GitHub repo Mindrally/skills into my ~/.claude/skills/android-development/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/Mindrally/skills.git /tmp/mindrally-skills && mkdir -p ~/.claude/skills && cp -r /tmp/mindrally-skills/android-development ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo into a temp folder: git clone https://github.com/Mindrally/skills.git /tmp/mindrally-skills
  3. Create the skills directory: mkdir -p ~/.claude/skills
  4. Copy just this skill: cp -r /tmp/mindrally-skills/android-development ~/.claude/skills/
  5. Verify the file exists: ls ~/.claude/skills/android-development/SKILL.md
  6. Restart Claude Code and try a prompt like "build this Android screen with MVI" to confirm the skill loads.
  7. If your team uses Jetpack Compose, edit the 'UI Framework Preferences' section of SKILL.md to match your stack.
