What problem does it solve?
This Skill eliminates the bottleneck of sequential subagent execution for complex, multi-phase software development tasks that require parallel coordination, reducing completion time for large-scale work like full code reviews or cross-team feature development.
Core Features & Use Cases
- Harness Mode Orchestration: Uses Claude Code's Workflow tools (parallel, pipeline, phase) to coordinate multiple subagents for concurrent task execution.
- Proven Workflow Patterns: Includes built-in support for fan-out/fan-in, adversarial verification, budget-aware dynamic parallelism, and worktree isolation for safe concurrent file modifications.
- Use Case: For example, run a full PR review that scans for bugs, performance issues, security flaws, and architecture inconsistencies in parallel, then verifies and synthesizes all results into a single actionable report.
Quick Start
Use the ultrawork skill to orchestrate parallel subagents to complete a full end-to-end code review of the current pull request, including bug scanning, performance checks, and security validation.
