When should I use the decomposing-plans skill?

Use it immediately after generating a monolithic implementation plan (typically via the writing-plans skill) but before starting the actual code implementation.

How does the skill identify parallel tasks?

The script analyzes the plan for tasks that modify different files and lack explicit sequence dependencies, grouping them into batches that can safely run at the same time.

What is the benefit of context reduction in this workflow?

By splitting a large plan into small task files, subagents only read the specific instructions they need, preventing 'lost in the middle' errors and saving significant token costs.

What happens if the script incorrectly identifies a dependency?

The skill generates a manifest.json file that you can manually edit to adjust parallel batches or task dependencies before proceeding to the execution phase.

Why is there a limit of two parallel subagents?

This constraint is designed to maintain high code review quality and prevent architectural drift, ensuring that parallel changes remain manageable and integrated.

生産性とワークフロー

Decomposes monolithic implementation plans into granular task files and identifies opportunities for parallel execution.

概要

This skill streamlines complex coding projects by breaking down large, monolithic implementation plans into smaller, focused task files. By analyzing file-based and explicit dependencies, it creates a structured execution manifest that identifies which tasks can safely run in parallel using up to two simultaneous subagents. This process significantly reduces context window usage for AI subagents by 90% and accelerates development timelines by up to 40% through efficient task orchestration.
