Core Features

Isolated Implementation Runs

Symphony creates autonomous runs for each piece of work, ensuring that tasks are handled independently, which can prevent interdependencies and conflicts.

Source: per README
Proof of Work

Agents provide evidence of their work, including CI status, PR review feedback, complexity analysis, and walkthrough videos, which can be crucial for tracking progress and ensuring quality.

Source: per README
Safe PR Landing

Symphony ensures that pull requests are landed safely, reducing the risk of introducing errors into the codebase.

Architecture

The architecture of Symphony is inferred to be modular, with a clear separation of concerns. It likely employs design patterns such as the Agent pattern for handling tasks, and the Observer pattern for monitoring and reporting. The code structure suggests a focus on task decomposition and a data flow that involves various skills and agents interacting with a worktree.
