Claude Orchestrator: A System for Efficiently Decomposing and Executing Complex Tasks

tl;dr

• Created a Claude Code version of Roo Orchestrator
• Unlike Roo which doesn't support parallel tasks, Claude Code's Task can execute in parallel

Introduction

I've been a regular user of Roo Orchestrator and wanted a Claude version of it.

mizchi

Orchestrator

Split complex tasks into sequential steps, where each step can contain multiple parallel subtasks.

Process

1. Initial Analysis
   • First, analyze the entire task to understand scope and requirements
   • Identify dependencies and execution order

• Plan sequential steps based on dependencies
