What problem does it solve? Deploying to production without a structured process leads to broken releases, undetected errors, and no way to recover quickly. This Skill provides a repeatable launch workflow covering readiness checks, 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 deploy. - Feature Flag & Staged Rollout Strategy: Defines a deploy-dark, team-enable, canary (5% → 25% → 50% → 100%) sequence 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, and a rollback plan template with trigger conditions and time-to-rollback targets. - Use Case: Before releasing a new expense-sharing feature, run the pre-launch checklist, deploy behind a feature flag, canary to 5% of users while watching error-rate thresholds, 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 release.
