Symphony
A tool that turns project work into isolated, autonomous coding-agent runs so a team can manage the work itself rather than supervise each agent, with an experimental Elixir reference implementation.
Symphony turns project work into isolated, autonomous implementation runs, so a team manages work instead of supervising individual coding agents. In an example workflow, Symphony watches a project board such as Linear for work, spawns agents to handle the tasks, and the agents complete the work and provide proof such as CI status, PR review feedback, complexity analysis and walkthrough videos before landing the change once it is accepted.
It is described as best suited to codebases that have already adopted harness engineering practices. A team can either implement Symphony itself from its published specification, or use the project's own experimental reference implementation, written in Elixir, following its setup instructions.
The project describes itself as a low-key engineering preview meant for testing in trusted environments. It is licensed under the Apache License 2.0.
