Deep Dive into Open Agent SDK (Part 4): Multi-Agent Collaboration

A single Agent, no matter how powerful, is just one executor. Real development tasks are often multi-step and multi-role: someone explores the codebase, someone designs a plan, then someone writes code and runs tests. A single Agent working alone easily bloats its context and loses efficiency. Open Agent SDK addresses this at three levels: Sub-Agents — The main Agent dynamically spawns sub-agents during execution, delegating specialized tasks Task System — Tracks progress and results of multi-st
