How does Ultrawork decide which AI model to use?

It classifies tasks by complexity, routing simple fixes to faster models like Haiku and complex logic to powerful models like Opus to optimize for both cost and performance.

When should I avoid using Ultrawork?

Avoid using it for tasks that have strict sequential dependencies or when you require a fully autonomous pipeline; in those cases, the 'autopilot' mode is more appropriate.

Can I use Ultrawork for tasks that require long builds?

Yes, it supports background execution for operations lasting over 30 seconds, such as package installs or test suites, allowing you to continue work in the foreground.

Does Ultrawork handle project state persistence?

No, Ultrawork is a component focused on execution. For full session persistence and comprehensive verification, you should use the 'ralph' mode which wraps Ultrawork functionality.

What is the main benefit of using Ultrawork?

Ultrawork significantly reduces total execution time by running independent coding tasks simultaneously instead of processing them one after another.

Productividad y Flujo de Trabajo

Accelerates development workflows by executing multiple independent coding tasks simultaneously through a high-throughput parallel agent engine.

Ultrawork is a specialized Claude Code skill designed to eliminate sequential bottlenecks by running multiple agents in parallel for independent tasks. It optimizes resource allocation by routing specific jobs to the most appropriate model tiers—using lightweight models for simple lookups and high-tier models for complex refactoring—while providing background execution for time-consuming operations like builds and tests. As a core component of the 'ralph' and 'autopilot' systems, Ultrawork focuses purely on high-throughput execution, making it an essential tool for developers looking to maximize productivity during large-scale code transformations or multi-file updates.
