What problem does it solve? Deploying to production without a checklist, monitoring, or a rollback plan leads to broken releases discovered by users instead of dashboards. This Skill structures the entire launch process so every deployment is reversible, observable, and incremental. ## Core Features & Use Cases - Pre-Launch Checklist: Covers code quality, security, performance, accessibility, infrastructure, and documentation gates that must pass before shipping. - Feature Flags & Staged Rollouts: Guides a deploy-dark, canary-at-5%, then 25% to 50% to 100% rollout with explicit advance/hold/rollback thresholds for error rate, latency, and business metrics. - Monitoring & Rollback Strategy: Defines what to monitor (application, infrastructure, client metrics), post-launch verification steps, error budget release gates, and a documented rollback plan with time estimates. - Use Case: Before releasing a new task-sharing feature, use this Skill to verify the pre-launch checklist, ship behind a feature flag, canary to 5% of users, and roll back instantly if error rates exceed 2x baseline. ## Quick Start Ask the agent to prepare a production launch plan with a pre-launch checklist, staged rollout, and rollback strategy for your feature.
