Agent Orchestrator: A Parallel Orchestration Platform for IDE to Manage 23 Terminal Coding Agents

Released by Composio as an open-source Agent Orchestrator (AO) in February 2026, this is an orchestration layer for parallel-coding agents: it supports 23 types of terminal agents including Claude Code, Codex and Cursor, adopts Git Worktree isolation by default, and automatically routes CI failures and review comments back to the corresponding sessions. It has gained over 8,700 GitHub stars so far. This paper outlines its workflow, plugin architecture and automatic feedback loop, and explains its complementary relationship with single-agent IDEs.
