What happens if one task fails during a parallel run?

The skill retains results from all successful tasks, displays specific error details for the failed task, and provides an option to re-run only the failed portion.

What is the expected speed improvement?

For scenarios like multi-file analysis or simultaneous component creation, users typically see a performance improvement between 55% and 67% compared to sequential execution.

Are there tasks that should not be parallelized?

Yes. Tasks that involve database migrations, simultaneous edits to the same file, or steps where the output of one is the input for the next should remain sequential.

How does the skill determine if tasks can be run in parallel?

The skill analyzes task dependencies to ensure they don't edit the same files, rely on each other's data outputs, or require a specific sequential order to function correctly.

生产力与工作流

Optimizes Claude Code performance by executing independent tasks in parallel to significantly reduce development and analysis time.

This skill empowers Claude Code to identify and execute multiple tasks simultaneously, moving beyond sequential processing for maximum efficiency. By intelligently analyzing dependencies between files and data, it distributes workloads—such as codebase analysis, concurrent testing, and multi-component implementation—across parallel agents. This ensures high-speed execution while maintaining quality through integrated reporting and robust error handling for complex, multi-faceted development cycles.
