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 complete launch framework covering readiness checks, gradual rollouts, observability, and rollback planning. ## Core Features & Use Cases - Pre-Launch Checklist: Covers code quality, security, performance, accessibility, infrastructure, and documentation gates before any deploy. - Feature Flags & Staged Rollout: Decouples deployment from release with a canary sequence (5% → 25% → 50% → 100%) and metric-based advance/hold/rollback thresholds. - Monitoring & Rollback Strategy: Defines what to monitor (error rates, latency, Core Web Vitals), post-launch verification steps, and a documented rollback plan with trigger conditions. - Use Case: Before releasing a new task-sharing feature, run the checklist, deploy behind a feature flag, enable it for 5% of users, watch error rates against baseline for 48 hours, then advance the rollout or roll back using the documented plan. ## Quick Start Ask the agent to prepare a production launch plan with a pre-launch checklist, staged rollout, and rollback strategy for your upcoming feature release.
