Does Ultrawork handle dependencies between tasks?

Yes, it identifies which tasks can run in parallel and which require sequential execution, ensuring prerequisites are met before launching dependent work.

Can I run builds in the background with this skill?

Absolutely. Ultrawork automatically uses background execution for operations exceeding 30 seconds, such as package installs and test suites, so you can continue working.

How does Ultrawork differ from Ralph or Autopilot?

Ultrawork is the core parallelism engine focused on execution speed. Ralph adds persistence and verification on top of Ultrawork, while Autopilot provides a full autonomous pipeline including both.

How does the model routing work?

It directs simple lookups to the Haiku tier, standard implementation to Sonnet, and complex refactoring to Opus to balance high performance with token cost efficiency.

Productividad y Flujo de Trabajo

Orchestrates high-throughput task completion by executing multiple independent AI agents simultaneously with intelligent model routing.

Ultrawork is a specialized performance engine designed to maximize productivity within Claude Code by eliminating sequential bottlenecks. It identifies independent coding tasks and delegates them to the most cost-effective model tiers—Haiku for simple lookups, Sonnet for standard implementations, and Opus for complex analysis—running them all in parallel. By supporting background execution for long-running processes like builds or installs, Ultrawork significantly reduces total development cycle times while providing lightweight verification to ensure code integrity.
