# Symphony
Symphony turns project work into isolated, autonomous implementation runs, allowing teams to manage
work instead of supervising coding agents.
[](.github/media/symphony-demo.mp4)
_In this [demo video](.github/media/symphony-demo.mp4), Symphony monitors a Linear board for work and spawns agents to handle the tasks. The agents complete the tasks and provide proof of work: CI status, PR review feedback, complexity analysis, and walkthrough videos. When accepted, the agents land the PR safely. Engineers do not need to supervise Codex; they can manage the work at a higher level._
> [!WARNING]
> Symphony is a low-key engineering preview for testing in trusted environments.
## Running Symphony
### Requirements
Symphony works best in codebases that have adopted
[harness engineering](https://openai.com/index/harness-engineering/). Symphony is the next step --
moving from managing coding agents to managing work that needs to get done.
### Option 1. Make your own
Tell your favorite coding agent to build Symphony in a programming language of your choice:
> Implement Symphony according to the following spec:
> https://github.com/openai/symphony/blob/main/SPEC.md
### Option 2. Use our experimental reference implementation
Check out [elixir/README.md](elixir/README.md) for instructions on how to set up your environment
and run the Elixir-based Symphony implementation. You can also ask your favorite coding agent to
help with the setup:
> Set up Symphony for my repository based on
> https://github.com/openai/symphony/blob/main/elixir/README.md
