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 verification before any deploy. - Feature Flags & Staged Rollouts: Implements flag-based releases with a canary sequence (5% → 25% → 50% → 100%) and metric-based advance/hold/rollback thresholds. - Monitoring & Rollback Plans: Defines what to monitor (error rates, latency, Core Web Vitals), post-launch verification steps, and documented rollback triggers and procedures. - Use Case: Before releasing a new task-sharing feature in a React app, use this Skill to run the pre-launch checklist, deploy behind a feature flag, canary to 5% of users, and monitor error rates against baseline thresholds before full rollout. ## Quick Start Ask the agent to prepare a production launch plan with a pre-launch checklist, staged rollout strategy, and rollback plan for your upcoming feature release.
