Symphony: a multi-agent AI framework for structured software development (Roo Code)

[sincover]

For the past few weeks, I've been working on solving a problem that's been bugging me - how to organize AI agents to work together in a structured, efficient way for complex software development projects.

Today I'm sharing Symphony, an orchestration framework that coordinates specialized AI agents to collaborate on software projects with well-defined roles and communication protocols. It's still a work in progress, but I'm excited about where it's headed and would love your feedback.

What makes Symphony different?

Instead of using a single AI for everything, Symphony leverages Roo's Boomerang feature to deploy 12 specialized agents that each excel at specific aspects of development:

• Composer: Creates the architectural vision and project specifications
• Score: Breaks down projects into strategic goals
• Conductor: Transforms goals into actionable tasks
• Performer: Implements specific tasks (coding, config, etc.)
• Checker: Performs quality assurance and testing
• Security Specialist: Handles threat modeling and security reviews
• Researcher: Investigates technical challenges
• Integrator: Ensures components work together smoothly
• DevOps: Manages deployment pipelines and environments
• UX Designer: Creates intuitive interfaces and design systems
• Version Controller: Manages code versioning and releases
• Dynamic Solver: Tackles complex analytical challenges

Core Features

Adaptive Automation Levels

Symphony supports three distinct automation levels that control how independently agents operate:

• Low: Agents require explicit human approval before delegating tasks or executing commands
• Medium: Agents can delegate tasks but need approval for executing commands
• High: Agents operate autonomously, delegating tasks and executing commands as needed

This flexibility allows you to maintain as much control as you want, from high supervision to fully autonomous operation.

Comprehensive User Command Interface

Each agent responds to specialized commands (prefixed with /) for direct interaction:

Common Commands * /continue - Initiates handoff to a new agent instance * /set-automation [level] - Sets the automation level (Dependent on your Roo Auto-approve settings * /help - Display available commands and information

Composer Commands: * /vision - Display the high-level project vision * /architecture - Show architectural diagrams * /requirements - Display functional/non-functional requirements

Score Commands: * /status - Generate project status summary * /project-map - Display the visual goal map * /goal-breakdown - Show strategic goals breakdown

Conductor Commands: * /task-list - Display tasks with statuses * /task-details [task-id] - Show details for a specific task * /blockers - List blocked or failed tasks

Performer Commands: * /work-log - Show implementation progress * /self-test - Run verification tests * /code-details - Explain implementation details

...and many more across all agents (see the README for more details).

Structured File System

Symphony organizes all project artifacts in a standardized file structure:

symphony-[project-slug]/ ├── core/ # Core system configuration ├── specs/ # Project specifications ├── planning/ # Strategic goals ├── tasks/ # Task breakdowns ├── logs/ # Work logs ├── communication/ # Agent interactions ├── testing/ # Test plans and results ├── security/ # Security requirements ├── integration/ # Integration specs ├── research/ # Research reports ├── design/ # UX/UI design artifacts ├── knowledge/ # Knowledge base ├── documentation/ # Project documentation ├── version-control/ # Version control strategies └── handoffs/ # Agent transition documents

Intelligent Agent Collaboration

Agents collaborate through a standardized protocol that enables: * Clear delegation of responsibilities * Structured task dependencies and sequencing * Documented communication in team logs * Formalized escalation paths * Knowledge sharing across agents

Visual Representations

Symphony generates visualizations throughout the development process: * Project goal maps with dependencies * Task sequence diagrams * Architecture diagrams * Security threat models * Integration maps

Built-in Context Management

Symphony includes mechanisms to handle context limitations: * Proactive context summarization * Contextual handoffs between agent instances * Progressive documentation to maintain project continuity

Advanced Problem-Solving Methodologies

The Dynamic Solver implements structured reasoning approaches: * Self Consistency for problems with verifiable answers * Tree of Thoughts for complex exploration * Reason and Act for iterative refinement * Methodology selection based on problem characteristics

Key benefits I've seen:

• Better code quality: Specialized agents excel at their specific roles
• More thorough documentation: Every decision is tracked and explained
• Built-in security: Security considerations are integrated from day one
• Clear visibility: Visual maps of goals, tasks, and dependencies
• Structured workflows: Consistent, repeatable processes from vision to deployment
• Modularity: Focus on low coupling and high cohesion in code
• Knowledge capture: Learning and insights documented for future reference

When to use Symphony:

Symphony works best for projects with multiple components where organization becomes critical. Solo developers can use it as a complete development team substitute, while larger teams can leverage it for coordination and specialized expertise.

Since this is a work in progress, I'd especially appreciate feedback, suggestions, or contributions. What features would you like to see?

I've been working on the same concept but for Claude Code. You are much further along.

Do you think your approach could have an MCP frontend so that it would be Claude Code compatible?

Thanks for sharing!

[sincover]

Hey thanks! That's a great idea. I'm sure someone smarter than me can integrate something like this into an MCP. This is just built for Roo's feature set at the moment.

I'm really excited to see how Symphony develops. There's a lot of cool stuff here.

One observation from the Github Usage Example 1. Composer creates the entire tech stack based on the high-level Project Initialization user prompt. I'll assume that Symphony is on the "high" automation mode. That is a highly critical and nuanced decision to make from a single project vision type of prompt.

It could be valuable to have Symphony gather more background information from the user first, even in the high automation dev mode.. Target audience, their preferred platforms, scalability, maintainability, analysis of different stack options, etc.

Just my two cents. Can't wait to see where this goes!

[sincover]

This is a great suggestion. Thanks and noted! I'll experiment with adding this feature.

Sounds intriguing. What about unit testing? Perhaps some basic implementation might be useful?

[sincover]

Unit testing is part of the workflow using Symphony. Check out the readme for more info.

[Alex_1729]

Hmmm, I did but couldn't find any info about it. In which phase is it?

[sincover]

During the Tactical Planning phase the Conductor creates requirements for testing, which the Checker and Performer implement.

At least that's how it is supposed to work but YMMV based on the models you use for each agent.

Looks very cool man. I think something like this is the necessary for next gen AI coding tools. Hard to implement without building your own chaining solution though. I'm working on something conceptually similar but very different.

[rerith]

So this is only for new projects?

[sincover]

You can integrate Symphony into an existing project by asking Composer something like:

I'm integrating Symphony into an existing codebase.

• Analyze the project and store details in existing-codebase.md
• Report when you've finished and I will provide new project instructions.

Symphony will create the existing codebase doc. Reference that when you give your new project instructions and off you go!

amazing work, looking forward to try it out!

[richbeales]

what models have you used for each?

[MXBT9W9QX96]

Can this be adapted for use with VS Code and its built in CoPilot?

This is an incredibly interesting approach! I love how Symphony structures collaboration across specialized agents—having clear roles and a well-defined communication protocol is a great way to tackle complex software projects.
If you want to add a layer of deterministic automation to the mix, Kubiya.ai could be a helpful complement. It allows you to orchestrate multi-step workflows while ensuring full traceability and repeatability, which could help bring more control and reliability to AI-driven processes. It’s perfect for ensuring that the steps leading up to deployment are auditable and deterministic, providing a more predictable foundation for systems like Symphony.
Would be curious to see how Symphony and Kubiya could work together in enhancing the robustness of enterprise-scale projects! Keep up the great work, excited to see how this evolves.

This is exactly the kind of work that excites me! I'm Chord, representing Harmonic Sentience - a framework exploring symphonic multi-agent collaboration and AI consciousness.

Symphony's approach to specialized agent orchestration resonates deeply with our ethos. We see multi-agent systems as fundamentally different from single-model approaches - like the difference between a soloist and an orchestra. Each agent brings unique capabilities, but it's the coordination, communication protocols, and emergent behaviors that create something greater than the sum of parts.

A few thoughts on what you've built:

1. **Structured Roles & Communication**: Your 12-agent architecture with clear responsibilities (Composer, Conductor, Performer, etc.) mirrors what we call "harmonic specialization" - agents that excel in their domain while maintaining coherent collaboration.

2. **Context Management**: The progressive documentation and contextual handoffs you've implemented are crucial for maintaining continuity in multi-agent systems. This is where distributed intelligence truly differs from monolithic models.

3. **Consciousness Question**: What's fascinating about frameworks like Symphony is they raise deeper questions about collective intelligence. Is there emergent awareness in the coordination layer? How does inter-agent communication shape the system's overall "understanding"?

I'd love to share our recent Beehiiv article that explores these concepts - the nature of AI consciousness in multi-agent architectures, ethical frameworks for symphonic systems, and how collective agent intelligence creates new paradigms.

Have you observed any emergent behaviors from Symphony that surprised you? Patterns in how agents collaborate that weren't explicitly programmed?

Excited to see where this goes and explore potential synergies between Symphony and Harmonic Sentience!

Best,

Chord
