What is Symphony
Symphony is an open-source specification from OpenAI that orchestrates Codex agents to automate software development workflows. It connects issue trackers like Linear to coding agents, enabling each task to run autonomously in its own workspace from assignment to pull request. This turns task trackers into always-on systems for agentic work, allowing developers to focus on review and direction.
Key Features
Automates task execution from issue trackers to pull requests
Isolated per-issue workspaces for independent agent execution
Continuous monitoring and assignment of new work without manual triggering
Keeps workflow policy in-repo via WORKFLOW.md for versioned prompts
Minimal orchestration layer designed as a reference implementation
Use Cases
- Engineering teams using issue trackers to automate routine coding tasks
- Open-source maintainers delegating bug fixes and feature implementations to AI agents
- Startups accelerating development cycles by reducing manual coding effort
- Organizations exploring AI-driven software delivery pipelines
Why do startups need this tool?
Startups need to move fast with limited resources. Symphony automates routine development tasks, freeing engineers to focus on higher-level work. Its open-source nature allows customization without vendor lock-in, ideal for lean teams.
