Use this skill when the user wants a deployment plan, rollout strategy, feature flag plan, canary plan, blue-green plan, rollback runbook, or release plan for a feature. Triggers include "deployment plan", "release plan", "rollout", "rollout plan", "canary", "blue-green", "feature flag", "feature flags", "progressive delivery", "rollback", "rollback plan", "release notes", "go-live", "production push", "CI/CD plan", "IaC change", "Terraform plan", "Kubernetes manifest", "helm chart change", or stage-6 SDLC work. Do NOT use for runtime monitoring after release (use sdlc-maintenance).
