What problem does it solve? Deploying to production without a structured process leads to broken releases, undetected errors, and no way to recover when things go wrong. This Skill provides a complete launch framework covering pre-launch verification, feature flags, staged rollouts, monitoring, and rollback planning. ## Core Features & Use Cases - Pre-Launch Checklist: Covers code quality, security, performance, accessibility, infrastructure, and documentation gates before any deployment. - Feature Flag Strategy: Decouples deployment from release with a defined flag lifecycle, ownership rules, and cleanup deadlines. - Staged Rollout with Thresholds: Defines a canary sequence (5% to 100%) with concrete advance, hold, and rollback decision thresholds for error rate, latency, and business metrics. - Monitoring and Rollback Plans: Specifies what to monitor post-launch and provides a rollback plan template with trigger conditions and time-to-recover targets. - Use Case: Before releasing a new task-sharing feature, run the pre-launch checklist, deploy behind a feature flag, roll out to 5% of users, compare error rates against baseline, and advance or roll back based on the threshold table. ## Quick Start Ask the assistant to prepare a production launch plan with a pre-launch checklist, staged rollout schedule, and rollback strategy for your next deployment.
