# Design Summary - Skill tier: complex - Trigger surface: release prep, release checklist, rollout coordination, rollback planning - Deterministic content: checklist stages, migration prompts, packet sections, and stakeholder message scaffolds - Flexible content: risk commentary, go/no-go judgment, and escalation notes - Package choice: `SKILL.md`, `agents/interface.yaml`, `manifest.json`, `references/`, `scripts/`, `evals/`, `input/`, `outputs/` - Boundary rule: use for release packet creation and readiness review, not for general project planning or one-off announcements - Validation goal: the generated packet must contain release scope, migration notes, rollout plan, rollback triggers, stakeholder communication, and an explicit decision block
