What is symphony?
Symphony turns project tasks into isolated, autonomous implementation runs. In the demo, it watches a Linear board, launches an agent when a task appears to handle it, and produces proof of work such as CI status, PR review feedback, complexity analysis, and walkthrough videos. Once approved, the agent safely lands the PR. You can implement it yourself from the spec or use the experimental Elixir reference implementation, and it is at the engineering preview stage for testing in trusted environments.
