SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ultrawork solves slow, sequential execution when you have multiple independent tasks that could be handled at the same time, wasting time and increasing overall runtime.

Core Features & Use Cases

  • Parallel agent execution: Launch multiple agents simultaneously for tasks with no dependency between them.
  • Model-tier routing: Route each subtask to an appropriate model tier (e.g., Haiku for simple lookups, Sonnet for standard work, Opus for complex analysis) to balance speed and cost.
  • Composable component behavior: Provide parallelism as a layer that is typically orchestrated by higher modes like ralph and autopilot, without adding persistence or full verification loops by itself.

Quick Start

Ask your system to run ultrawork to delegate several independent subtasks concurrently, such as implementing an endpoint, adding integration tests, and updating related documentation in parallel.

FAQPage Schema
How do I run parallel Claude Code tasks to reduce total completion time?

Parallel Claude Code tasks run by firing independent calls simultaneously and explicitly passing the model for each delegation, reducing total completion time for concurrent work items while dependent steps remain sequenced.

Can I route different subtasks to specific model tiers in Claude Code?

Model-tier routing in Claude Code assigns each subtask to an appropriate model tier, routing simple lookups to Haiku, standard work to Sonnet, and complex analysis to Opus to balance execution speed and operational cost.

What is multi-agent orchestration for independent tasks?

Multi-agent orchestration for independent tasks launches multiple agents simultaneously to handle work items with no dependencies between them, enabling parallel execution instead of slow sequential processing.

Does parallel execution in Claude Code support background jobs for long-running operations?

Parallel execution in Claude Code optionally uses background execution for long-running operations, applying lightweight completion checks to monitor progress without blocking other concurrent independent subtasks.

When should I not use parallel execution for task delegation?

You should not use parallel execution for task delegation when steps have dependencies between them, because this approach requires independent work items to run concurrently while dependent steps must remain sequenced.

Do I need orchestration modes to use parallel execution in Claude Code?

Parallel execution in Claude Code does not require orchestration modes to function, acting as a composable layer that is typically orchestrated by higher modes like ralph and autopilot without adding persistence loops.
