When you need multiple Claude agents working in parallel with clear handoffs and decision tracking, this orchestration framework gives you a structured naval command metaphor. It walks you through mission planning (sailing orders, optional seven-question estimate), drafts a battle plan with quality gates, coordinates parallel agent execution, and produces a documented mission log. The Estimate phase is the real substance here: it forces reconnaissance, intent clarification, and dependency mapping before any code changes. Best for refactors or features that span multiple subsystems where you need auditable decisions and can't afford agents stepping on each other. Overkill for simple tasks, but the discipline pays off when coordination overhead would otherwise eat your context window.
