symphony

What problem does it solve?

Symphony enables orchestration of parallel phase execution from plan files that contain symphony-phases blocks. It builds a dependency DAG and executes phases concurrently, with artifact propagation between phases and automatic dependency resolution using Kahn's algorithm.

Core Features & Use Cases

• Orchestrate parallel phase execution from plan files containing symphony-phases blocks.
• Parse plan blocks, build a dependency DAG via Kahn's algorithm, and run phases concurrently using the Task tool.
• Propagate artifacts between phases and automatically resolve dependencies.
• Use case: You have a multi-step deployment plan with interdependent tasks; you want phases to run in parallel wherever possible, while preserving dependency order.

Quick Start

Create a plan.md that includes a symphony-phases block and invoke the Symphony runner with the plan to start orchestration.
