What problem does it solve? Shipping an Android app is risky because an installed APK or AAB cannot be recalled, so a bad release reaches users permanently. This Skill enforces a rigorous pre-launch checklist, staged rollout plan, and remote kill-switch strategy so releases to Google Play or Firebase App Distribution happen with controlled risk. ## Core Features & Use Cases - Pre-Launch Checklist: Covers code quality, Proguard/R8, security and permissions, Room migrations, accessibility, and Play Console release configuration. - Two-Tier Ship Verdict: Distinguishes GO (production) from GO (demo/portfolio) by enumerating production blockers such as untested acceptance criteria or missing Room migrations. - Staged Rollout & Monitoring: Defines 1% to 100% rollout stages with Crashlytics, ANR, and rendering thresholds, plus Remote Config feature flags as a kill-switch. - Use Case: Before pushing a new version with a Room schema change to the Play Store, run the checklist to confirm migrations are tested, then roll out at 5% while monitoring Crashlytics before advancing. ## Quick Start Use the shipping-and-launch skill to run the pre-launch checklist and produce a ship verdict for my Android release.
