Android Kotlin Compose Development

Context ladder (smaller load first; full references stay complete):

1. This file (SKILL.md) - routing, stop rules, examples.
2. references/*-quick.md when listed below - required/forbidden + section links (~40 lines).
3. One target section in the full references/*.md - code samples and checklists only.
4. INDEX-sections.md - anchor dump only when quick routing is insufficient.

Forbidden: load INDEX-sections.md or an entire multi-thousand-line reference when one section or a quick file covers the task.

Route tasks through the Quick Reference table. When no row matches, or the task needs greenfield bootstrap: workflows.md. Full file list: INDEX.md.

Required:

• Existing project: read settings.gradle.kts, gradle/libs.versions.toml, and the app module build file before copying from assets/ - dependencies.md, modularization.md. Stack migrations: migration.md.
• Greenfield: workflows.md → "Creating a new project?"
• After module, DI, navigation, Room schema, or AGP/Kotlin/KSP changes: ./gradlew help then :app:assembleDebug (use the real app module name) - gradle-setup.md.

Outside-repo stop rules (do not substitute repo edits): Play upload, tracks, rollout, versionCode - android-ci-cd.md; Play Integrity prerequisites (Console/Cloud setup) - android-security-quick.md; production adb install / pm clear - testing.md.
