Saga

When you need Claude to autonomously build a medium-to-large feature end-to-end, this spins up an orchestrator-worker architecture that treats specs like contracts. It forces you to nail down every validation criterion up front in a hierarchical spec tree (saga, milestones, tasks), then delegates implementation to worker subagents while keeping the orchestrator's context clean. The bet is simple: if the spec is airtight enough that a worker can self-verify against it, you can parallelize work and step away. It writes everything to a persistent directory under ~/.sagas so you can resume across sessions. Best for features that would normally fragment your context across dozens of turns.
