What problem does it solve? Deploying to production without a checklist, monitoring, or a rollback plan leads to undetected failures, big-bang releases, and slow incident response. 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 any deploy. - Feature Flags and 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 and Rollback Strategy: Specifies what to monitor (application, infrastructure, client metrics), post-launch verification steps, and a documented rollback plan with trigger conditions and time estimates. - Use Case: Before releasing a new task-sharing feature, run the checklist, deploy behind a feature flag, canary to 5% of users while watching error rates, then roll out gradually with a documented rollback path. ## Quick Start Ask the agent to prepare a production launch plan with a pre-launch checklist, staged rollout, and rollback strategy for your upcoming release.
