OpenAI released Symphony — a project-level orchestrator that watches your Linear board, spawns isolated coding agents per task, and lands PRs automatically. Engineers manage work at a higher level instead of supervising agents one by one.
They shipped an Elixir reference implementation and explicitly said "implement it in any language you want." So I built the Go version — with multi-agent team coordination on top, so multiple agents can collaborate across different parts of a codebase in parallel. Currently supports openai/codex and opencode as agent runtimes.
