Agent Orchestrator (AO) is an open-source multi-agent harness developed by Untrivial-ai. Built to coordinate and execute autonomous development workflows, it provides a orchestration environment designed to run and supervise terminal-based AI coding agents across complex engineering tasks. In day-to-day operation, Agent Orchestrator manages agent lifecycles and background execution sessions, leveraging tmux session management to isolate agent states and run processes concurrently. It natively supports configurable skill directories—such as `.agents/skills` and `.claude/skills`—allowing teams to plug in agent capabilities, bug triage workflows, and custom tool interfaces directly into terminal development sessions. Agent Orchestrator differentiates itself by functioning as a session-aware harness that coordinates persistent agent execution environments rather than operating as a standalone interactive chat prompt. By managing state across sessions and decoupling agent logic through modular skill definitions, it enables parallelized task distribution and multi-agent execution in local development workflows. Agent Orchestrator is distributed as an open-source project on GitHub under standard community licensing, with an active repository structure supporting CI-driven security checks and developer workflows.
