Mobile Checkpoint Skill

Git-based checkpoint workflow for Android/KMP development: save a known-good state before a risky operation, restore cleanly if it goes wrong. Checkpoints are ordinary git commits plus a checkpoint/* tag — no extra tooling.

When to Use

Before risky operations:

• Large refactors (MVI migration, architecture changes)
• Gradle/AGP/Kotlin upgrades, dependency bumps in gradle/libs.versions.toml, ./gradlew wrapper --gradle-version <x>
• Manifest changes (permissions, components)
• Navigation restructuring
• Experimental features

After milestones:

• Feature completion, all tests passing, successful release build
