What problem does it solve? Keeping an existing Android project's toolchain current is risky because Gradle, AGP, Kotlin, KSP, and the Compose BOM form a coupled version matrix, and a wrong bump silently breaks the build or misses Play targetSdk deadlines. This Skill inventories the current toolchain, researches compatible versions from primary sources, plans an ordered upgrade path, and applies each step behind a green ./gradlew build gate. ## Core Features & Use Cases - Three operations: audit (read-only currency report with severities), plan (researched, ordered upgrade path), and apply (one confirmed, build-gated step at a time). - Coupling-aware upgrades: handles AGP↔Gradle↔Kotlin↔KSP↔Compose constraints, the AGP 9 built-in-Kotlin migration, kapt removal, and targetSdk behaviour-change walks. - Verification and logging: checks 16 KB page-size alignment on release artifacts, runs osv-scanner and Renovate hygiene checks, and records every run in a toolchain log. - Use Case: Ask it to raise AGP, Kotlin, and targetSdk on an existing app; it inventories versions, fetches current compatibility facts, walks the targetSdk behaviour changes, and applies each bump only after the previous build stays green. ## Quick Start Ask the assistant to update the Android project's AGP, Kotlin, and targetSdk to current compatible versions using the android-toolchain-upgrade skill.
