Beyond Single-Agent Loops: How We Built Multi-Agent Orchestration in Octo

Short summary

The team behind Octo shares lessons from extending Loop Engineering — the practice of building iterative agent loops instead of perfecting single prompts — from single-agent to multi-agent orchestration. They identify key failure modes of single-agent loops in production: context window exhaustion, lack of observability for long-running tasks, and poor parallel-agent management. Their solution introduces a dedicated task execution layer called the Loop, separating conversational messaging from async task dispatch, and classifies agents into Assistants (managerial, user-specific) and Specialists (stateless workers).

• •Single-agent loops break down for real organizational work requiring multiple interconnected roles and shared state
• •Octo built a separate task execution layer (the Loop) on top of messaging to handle long-running, multi-agent workflows
• •Agents are classified as Assistants (user-specific, managerial, long-term memory) vs Specialists (stateless, task-focused workers)
