Does Ultrawork ensure tasks are actually finished?

Yes, it includes a persistence enforcement rule that requires a zero-error verification checklist to be met before the agents stop working.

What is Ultrawork in Claude Code?

Ultrawork is a specialized skill that activates maximum performance mode, allowing Claude to orchestrate multiple sub-agents in parallel for faster, high-throughput task completion.

Can I run background tasks with this skill?

Yes, Ultrawork uses non-blocking background execution for time-consuming tasks like npm installations, Docker builds, and large test suites.

What specialized agents are included?

The skill includes 32+ specialized agents for domains such as architecture, security review, frontend design, TDD, and codebase exploration.

How does smart model routing save tokens?

It intelligently directs simple lookups to the affordable Haiku model while reserving the powerful Opus model for complex analysis, optimizing your token usage.

Productivity & Workflow

Optimizes Claude Code performance through parallel agent execution, background operations, and cost-efficient model routing.

About

Ultrawork is a high-performance orchestration skill for Claude Code designed to handle complex, multi-faceted projects by running multiple agents in parallel. It boosts developer productivity by delegating sub-tasks to specialized agents across tiered models—Haiku, Sonnet, and Opus—based on task complexity to maximize speed and minimize token costs. With built-in support for non-blocking background operations and a strict persistence enforcement layer, Ultrawork ensures that large-scale refactors, intensive builds, and thorough research tasks are completed and verified without manual intervention.

Key Features

Tiered model routing (Haiku, Sonnet, Opus) to optimize cost and performance
Strict persistence enforcement with automated verification checklists
2,142 GitHub stars
Domain-specific delegation to specialized agents like architects and executors
Parallel agent execution for simultaneous task completion
Non-blocking background operations for long-running builds and installs

Use Cases

Running intensive test suites and build processes in the background during active development
Executing complex codebase refactorings across multiple modules simultaneously
Managing high-throughput research or data analysis tasks using cost-efficient model tiers
