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 so every deployment is reversible, observable, and incremental. ## Core Features & Use Cases - Pre-Launch Checklists: Covers code quality, security, performance, accessibility, infrastructure, and documentation gates before any deploy. - Feature Flags & Staged Rollouts: Defines a flag lifecycle and a canary sequence (5% → 25% → 50% → 100%) with explicit advance/hold/rollback thresholds for error rate, latency, and business metrics. - Monitoring & Rollback Planning: Specifies what to monitor (application, infrastructure, client metrics), post-launch verification steps, error budget release gates, and a rollback plan template. - Use Case: Before releasing a new task-sharing feature, run the pre-launch checklist, deploy behind a feature flag, canary to 5% of users while watching error rates against the thresholds table, and keep a documented rollback plan ready. ## Quick Start Ask the assistant to prepare a production launch plan with a pre-launch checklist, staged rollout, and rollback strategy for your upcoming feature release.
