Symphony

Symphony is an agentic workflow manager and autonomous software implementation engine. It serves as an orchestrator for large language model coding agents, converting high-level project requirements and task board items into verified pull requests.

The system manages an autonomous development workflow by delegating implementation runs to agents that handle end-to-end feature development and bug fixes. It generates automated pull requests backed by proof-of-work verification, ensuring that code contributions are validated before human review.

The platform coordinates a cycle of planning, coding, and verification using isolated run environments and state-based tracking to maintain progress. It integrates with task boards to translate project tickets into technical specifications and executable tasks.

    Claude Code is a command-line interface and multi-agent orchestration framework designed for autonomous software engineering. It enables AI agents to perform codebase modifications, debugging, and Git workflow management while coordinating multiple specialized agents to decompose and execute complex engineering tasks in parallel. The system distinguishes itself through a high degree of isolation and safety, utilizing Git worktrees to create independent working directories for concurrent agents and implementing a tiered permission system that combines user rules, project policies, and OS-level
