Multi-Agent Collaboration: How Distributed AI Agents Work Together to Solve Complex Problems

TL;DR

• Multi-agent systems (MAS) consist of autonomous agents that collaborate, share information, and adapt dynamically to solve complex problems beyond individual capabilities.
• MAS architectures include centralized supervisory models, decentralized peer-to-peer networks, and hybrid blackboard frameworks, offering scalable, resilient, and flexible AI workflows.
• Effective multi-agent collaboration enables enhanced scalability, fault tolerance, and specialization, improving efficiency across diverse enterprise workflows.
  • Key challenges such as communication complexity, coordination, security, state consistency, and observability require robust design, clear protocols, and monitoring.
• Platforms like Kubiya.ai empower organizations to implement production-ready multi-agent workflows with advanced orchestration, security features, seamless integrations, and support for self-organizing agent networks.

There has been a growing trend in artificial intelligence towards building systems composed of multiple collaborating agents rather than relying on a single monolithic AI. This approach, known as multi-agent collaboration, allows autonomous agents each with its own specialization to work together and solve complex problems that would be difficult or impossible for any individual agent to handle alone.

For developers, this shift opens up exciting possibilities. Instead of building one all-encompassing AI model, they can architect modular systems where each agent focuses on a particular aspect of a larger task. These agents communicate, coordinate, and share information effectively, enabling scalable and flexible AI workflows that can adapt to evolving enterprise needs.

Advancements in large language models and distributed AI frameworks have made implementing multi-agent systems more practical and powerful. Developers can leverage sophisticated tools and SDKs to orchestrate agent interactions, design structured workflows, and seamlessly integrate AI capabilities into operational environments.

This article delves into the key concepts and architectural approaches behind multi-agent collaboration from a developer’s viewpoint. It covers essential technologies, design techniques, and practical examples that illustrate how distributed agents can collaborate to transform complex processes into automated, manageable workflows.

Understanding Multi-Agent Collaboration

To understand how multi-agent collaboration actually works, we first need to clarify what multi-agent systems are. Simply put, these systems are made up of multiple independent agents, each responsible for specific tasks, that work together by sharing information and coordinating actions. This teamwork allows them to solve problems that no single agent could handle alone.

A multi-agent system (MAS) is made up of multiple AI agents working together to perform tasks for a user or system. Each agent has its own capabilities but collaborates to achieve shared goals. MAS can include hundreds or even thousands of agents, making them suitable for large-scale, complex problems.

At their core, AI agents operate autonomously, planning their workflows and using tools like APIs or databases to accomplish tasks. Unlike traditional AI models, these agents can update their knowledge and coordinate actions dynamically. Their collaboration involves communicating directly or indirectly by changing their shared environment, which allows for distributed problem-solving and efficient task completion.

Multi-agent systems can be organized in different ways depending on the needs of the application:

• In centralized networks, a central controller coordinates all agents, making communication straightforward but risking a single point of failure.
• In decentralized networks, agents communicate directly with each other, improving system robustness but adding complexity to coordination.
• Agents may be arranged hierarchically, grouped in coalitions (temporary partnerships), or work as teams depending on the task.
• Their behavior often mirrors natural systems, like flocking birds or swarming insects, to achieve effective coordination at scale.

These systems are widely used across industries from managing transportation and supply chains to healthcare and defense thanks to their flexibility, scalability, and ability to specialize in different domains.

Now that we have a clear understanding of what multi-agent systems are and how they function, it’s important to see how they differ from traditional single-agent AI models. This distinction highlights why multi-agent collaboration is often the preferred choice for handling complex, large-scale tasks.

Understanding the Gap: Single-Agent vs Multi-Agent AI

Single-Agent Models:

A single AI agent handles the entire task independently, making decisions and executing actions on its own. It works well for focused tasks with clear boundaries but can struggle with complex or long-running workflows. Single agents are simpler to build and manage but lack collaboration and may face limitations in scalability and adaptability.

Let’s consider a scenario where a single-agent AI is put to work. Imagine an AI-powered helpdesk chatbot in a large enterprise designed to handle straightforward employee requests, such as resetting passwords or checking leave balances. This agent performs well with these simple tasks but faces challenges when issues require multiple skill sets—like combining HR policy understanding with IT troubleshooting or coordinating approvals across departments. The chatbot’s single-focus model limits its ability to handle such complex, cross-functional workflows effectively.

Multi-Agent Collaboration:

In contrast, multi-agent systems consist of multiple specialized agents working together toward a shared goal. Each agent handles a part of the task and communicates with others to coordinate actions. Let’s revisit our helpdesk scenario. Instead of relying on one chatbot, a multi-agent system might deploy separate specialized agents: one focused on IT issues like password resets, another expert in HR policy, and a third managing approval workflows across departments. These agents share information and coordinate their actions seamlessly. For example, when a request involves both IT and HR concerns, the agents communicate to exchange relevant data and jointly resolve the issue efficiently.

This setup allows for greater scalability, flexibility, and problem-solving ability, especially for complex or multi-domain workflows. Multi-agent collaboration also enhances fault tolerance; if one agent encounters a problem or fails, others can continue their work without disrupting the entire system. By dividing tasks among specialized agents, enterprises can ensure more accurate responses, faster resolution times, and a better overall user experience.

Key Differences: Multi-Agent vs Single-Agent

To better understand how multi-agent collaboration achieves its advantages, let’s explore how tasks and responsibilities are divided among different types of agents primarily the supervisor (orchestrator) and the specialist agents

The Role of Supervisors and Specialists in Multi-Agent Collaboration

Multi-agent collaboration succeeds by dividing complex workflows among agents specializing in distinct roles. This design helps overcome the limits of single-agent systems and efficiently tackles large-scale problems.

Supervisor (Orchestrator) Agent:

• Acts like a conductor or project manager who oversees the entire collaboration.
• Sets the overall goals and breaks them into manageable tasks.
• Assigns tasks to specialist agents based on their expertise.
• Manages communication and data flow among agents to keep work synchronized.
• Integrates the outputs of specialists into a final, coherent result.
• Dynamically adapts plans if conditions change or problems arise, ensuring the project stays on track.

Specialist Agents:

• Focus on specific, well-defined tasks or domains, such as IT support, HR policy, or approval processing.
• Bring deep knowledge and optimized workflows for their areas.
• Communicate regularly with the supervisor for guidance and reporting.
• May interact with other specialists to share data and coordinate overlapping work.

To provide an example of these roles in action, think of a multi-agent helpdesk system where a supervisor coordinates specialized agents to efficiently manage complex employee requests.

Multi-Agent Helpdesk Handling a Complex Employee Request

Consider an employee submitting a request like:

"I’m unable to access my email, and I need to apply for emergency leave due to a family issue. Also, I require managerial approval to finalize the leave."

Here’s how a multi-agent system would manage this:

Step 1 Supervisor Agent Receives the Request:

The supervisor agent parses the request and identifies multiple needs: a technical issue (email access), HR-related leave application, and an approval process.

Step 2 Task Delegation:

The supervisor splits the request:

• Directs the IT specialist agent to diagnose the email access problem.
• Sends the leave application details to the HR specialist agent to check eligibility and prepare the leave request.
• Prepares to involve the approvals agent for managerial sign-off once the leave request is ready.

Step 3 Specialist Agent Actions:

• The IT agent checks the employee’s account status, identifies a locked account, and initiates a password reset or unlock process.
• The HR agent verifies the employee’s leave balance, confirms qualification for emergency leave, and formats the request.

Step 4 Coordination:

Once the HR agent finalizes the leave request, the supervisor instructs the approvals agent to notify the manager for approval.The approvals agent manages reminders and tracks manager responses.

Step 5 Aggregation of Responses:

The supervisor collects status updates from all specialists.Once the IT issue is resolved and leave approved, the supervisor compiles a single, clear response:

"Your email access issue has been resolved with a password reset. Your emergency leave request has been approved by your manager. Please check your inbox for confirmation details."

Step 6 Delivery:

The unified answer is sent back to the employee, addressing all concerns comprehensively without the employee needing to interact with multiple systems separately.

This collaborative approach streamlines complex problem-solving, reduces response times, and provides a seamless user experience. It also allows each agent to focus on their strengths while the supervisor maintains coherence and progress.

This detailed example highlights how different agents in a multi-agent system collaborate seamlessly to address complex, multifaceted requests. At the heart of such collaboration lies effective communication and coordination, which are essential for the system to function smoothly and achieve its objectives. Understanding these fundamentals is key to appreciating how multi-agent systems operate successfully across diverse applications.

Communication and Collaboration in Multi-Agent Systems

To truly understand how multi-agent systems work together efficiently, let's dig deeper into their core communication and collaboration strategies with both technical detail and concrete examples for developers.

1. Purpose

• Communication enables agents to share state, goals, and situational data.
• Collaboration allows agents to align efforts, distribute tasks, and solve problems too complex for a single agent.

2. Methods and Protocols

Multi-agent systems communicate and collaborate via various methods (high-level communication styles) and protocols (concrete rules for message exchange) to ensure the right information reaches the right agent effectively and efficiently.

Common Communication Methods

• Rule-Based: Agents follow predefined rules to determine when and what to communicate.
• Role-Based: Agents have specific roles and collaborate based on their specialized functions, following role-specific protocols.
• Event-Driven: Agents react dynamically to events or messages, enabling flexible, asynchronous communication.

Core Communication Protocols

• Request-Response: One agent sends a direct query or task to another and waits for a reply. Useful for task delegation and result retrieval.
• Publish-Subscribe: An agent (publisher) broadcasts messages to any number of agents (subscribers) interested in certain topics. Decouples sender and receiver, enabling scalable and flexible communication.
• Shared Blackboard: Agents coordinate via a shared space where they publish information and read others’ updates asynchronously, supporting complex, loosely coupled interactions.

Having explored the foundational communication methods and protocols that enable agents to exchange information reliably and efficiently, it is crucial to understand how agents collaborate at a higher architectural level.

Strategies

Multi-agent collaboration does not only depend on communication techniques but also on the overall strategies that define how agents coordinate their actions to fulfill complex tasks collectively.

1. Centralized Collaboration

In centralized collaboration, a supervisor or orchestrator agent controls the workflow by allocating specific tasks to multiple specialist agents while gathering and consolidating their inputs. This centralized authority ensures coordinated, consistent performance and global optimization.

Examples:

• Air Traffic Control System: A central tower agent manages communication with all aircraft agents, directing landing and takeoff sequences to avoid collisions and optimize runway usage.
• Smart Manufacturing Factory: A master controller agent assigns assembly tasks to different robot agents specialized in welding, painting, or inspection, synchronizing the workflow for maximum efficiency.
• Multi-Agent Deep Reinforcement Learning (MADRL)Algorithms like QMIX use centralized training where a global agent evaluates joint performance, guiding decentralized agents during execution.

Pros and Cons:

• Pros: Simplified coordination, consistent global strategy, easy conflict resolution
• Cons: Single point of failure, scalability bottleneck, higher latency in large systems

2. Decentralized Collaboration

Decentralized collaboration removes the central control agent and instead employs peer-to-peer communication and negotiation among agents. Each agent operates autonomously while sharing partial information with neighbors. This enhances scalability and fault tolerance but requires sophisticated protocols to maintain coherence.

Examples:

• Vehicular Swarms for Traffic Management: Autonomous vehicle agents communicate with nearby vehicles to coordinate lane changes and avoid collisions without central traffic control.
• Wireless Sensor Networks for Environmental Monitoring: Sensor agents collect data and locally decide when and what to share, collectively identifying environmental hazards.
• Distributed Robotics: Robot teams explore and map unknown terrain, coordinating movements flexibly based on local interactions.

Pros and Cons:

• Pros: Highly robust, scalable, no single point of failure
• Cons: Complex coordination, potential information inconsistencies, higher communication overhead

3. Hybrid/Blackboard Model

The hybrid approach combines centralized and decentralized methods through a shared blackboard or common workspace. Agents asynchronously post partial results or events to the blackboard, which others read and use to guide their actions. A master agent can still orchestrate global goals, balancing flexibility with coordinated control.

Examples:

• Collaborative Robotics on Factory Floors: Multiple robots contribute progress updates to a shared blackboard while a supervisory agent monitors overall assembly status.
• Complex AI Decision-Making Systems: Specialized agents update a shared knowledge graph or state, enabling integrated multimodal reasoning and planning.
• Multi-Agent Dialogue Systems: Conversational AI agents share intermediate utterance embeddings on a blackboard to maintain dialogue context and coherence.

Pros and Cons:

• Pros: Balances coordination and autonomy, facilitates dynamic replanning, supports rich interactions
• Cons: Implementation complexity, potential performance overhead due to synchronization, requires well-defined data sharing models

Let’s shift from the “big picture” of how we organize agents to the “code-level” patterns you’ll actually implement. Next up, we’ll break down three collaboration styles rule-based, role-based, and event-driven and show how they map to real-world code and systems so you can pick the right one for your project.

Collaboration Types in Multi-Agent Systems

Rule-Based Collaboration

• Agents follow predefined rules or logical conditions to decide on actions and communication.
• Predictable and consistent, ideal for highly structured or repetitive tasks.
• Uses if-then logic, state machines, or decision trees.

Enterprise Example (Centralized Strategy): Banking Fraud Detection System - A centralized supervisor agent orchestrates fraud detection by sending transaction data to specialized rule-based agents. Each agent follows strict rules: "IF transaction amount > $10,000 AND location != user's home country THEN flag for review." The system ensures consistent, compliant fraud detection across all branches.

Developer Example (Centralized Strategy): CI/CD Pipeline Management - A master orchestrator agent manages deployment workflows with rule-based worker agents. Each agent follows deployment rules: "IF unit tests pass AND security scan clean THEN deploy to staging." This ensures consistent, reliable deployments across development teams.

Role-Based Collaboration

• Each agent has clearly defined roles and responsibilities.
• Agents coordinate through specialized functions and access rights.
• Mirrors human team dynamics with expertise-based collaboration.

Enterprise Example (Decentralized Strategy):Customer Support Ecosystem - Different agent roles communicate peer-to-peer without central control: "Triage Agents" classify tickets, "Technical Agents" handle complex issues, "Escalation Agents" manage high-priority cases. Each role has specialized knowledge and communicates directly with relevant agents, scaling support operations efficiently.

Developer Example (Hybrid Strategy):DevOps Multi-Agent Platform - Role-based agents in a hybrid model: "Monitoring Agents" post alerts to a shared blackboard, "Incident Response Agents" react to critical alerts, "Analytics Agents" track patterns. A supervisor ensures overall system health while agents operate autonomously within their domains.

Event-Driven Collaboration

• Agents react dynamically to events or environmental changes.
• Supports asynchronous, loosely-coupled interaction.
• Implemented with message queues, publish-subscribe, or blackboard architectures.

Enterprise Example (Hybrid Strategy): Supply Chain Management System - Event-driven agents react to supply chain disruptions: When inventory drops below threshold, "Procurement Agents" automatically trigger reorders, "Logistics Agents" optimize shipping routes, "Finance Agents" approve purchase orders. All updates flow through a shared blackboard while a master agent ensures budget compliance.

Developer Example (Decentralized Strategy): Microservices Monitoring Platform - Event-driven agents in distributed architecture: "Health Check Agents" monitor service status, "Load Balancer Agents" respond to traffic spikes, "Alert Agents" notify teams of issues. Agents communicate peer-to-peer through event streams, enabling rapid response to system changes without centralized coordination.

Takeaway: Mastering both the right communication protocols (request-response, pub/sub, shared blackboard) and collaboration strategies (centralized, decentralized, hybrid) empowers you to architect robust, efficient multi-agent systems that thrive in production environments.

Understanding these communication strategies is essential before selecting an architectural pattern, as they directly impact coordination, scalability, and fault tolerance.

Architectural Patterns for Multi-Agent Systems

To build robust, maintainable, and scalable multi-agent applications, developers can draw on several proven architectural patterns. Each pattern balances control, flexibility, and performance in different ways. Integrate these blueprints into your system design to unlock the full potential of distributed AI collaboration.

1. Hierarchical Architecture

Organizes agents into tiers, with top-level supervisors delegating to mid-level coordinators and bottom-level specialists. Supervisors maintain a global view and break down complex goals; coordinators manage subdomains; specialists execute focused tasks.

Example: In an enterprise document processing system, a top-level agent oversees the entire pipeline, delegating summarization to one mid-level agent and data extraction to another, each controlling their worker agents.

Pros: Simplifies large-scale orchestration, aligns well with organizational structures, supports specialization and clear responsibility boundaries.

Cons: Can introduce bottlenecks at higher levels, less resilient to supervisor failure, increased communication overhead.

2. Orchestrator–Worker Pattern

A dedicated orchestrator agent decomposes incoming work into units and distributes them to worker agents through task queues or pub/sub channels. Workers process tasks independently and return results to the orchestrator, which aggregates responses.

Example: In a data ETL pipeline, the orchestrator divides data chunks, sends them to worker agents for transformation, and collates processed results.

Pros: Clear task ownership and result aggregation, excels in batch processing, good fault isolation at worker level.

Cons: Central orchestrator can become a single point of failure, possible bottleneck in aggregation phase, requires careful task queue management.

3. Peer-to-Peer Networks

Agents connect in a mesh without central authority, discovering and negotiating tasks directly with peers. Maximizes fault tolerance and prevents single points of failure.

Example: Autonomous vehicles in an ad hoc sensor network share road status information and coordinate route planning without centralized control.

Pros: Highly resilient and scalable, suited for dynamic environments, no dependency on central coordinator.

Cons: Complex coordination and consistency challenges, potential communication overhead, harder to debug and monitor.

4. Hybrid Architectures

Combine elements of hierarchical, orchestrator–worker, and peer-to-peer patterns to balance control and resilience. For example, a top-level orchestrator manages major workflow milestones while worker agents form peer-to-peer clusters for localized coordination.

Example: A logistics platform uses centralized dispatch for large shipments but peer-to-peer routing among local delivery drones.

Pros: Flexible, adapts to load and failure scenarios, mixes governance with agent autonomy.

Cons: Increased architectural complexity, requires sophisticated monitoring and failure handling.

5. Event-Driven & Message-Based Models

Use asynchronous message brokers, pub/sub channels, or event streams to decouple senders and receivers. Agents publish events/tasks and subscribe to relevant channels.

Example: In a real-time monitoring dashboard, agents publish alerts and subscribe to updates to react quickly.

Pros: Enables elastic scaling, non-blocking communication, loosely coupled system components.

Cons: Difficult to debug message flows, eventual consistency considerations, requires robust messaging infrastructure.

6. Payload Referencing

Use asynchronous message brokers, pub/sub channels, or event streams to decouple senders and receivers. Agents publish events/tasks and subscribe to relevant channels.

Example: In a real-time monitoring dashboard, agents publish alerts and subscribe to updates to react quickly.

Pros: Enables elastic scaling, non-blocking communication, loosely coupled system components.

Cons: Difficult to debug message flows, eventual consistency considerations, requires robust messaging infrastructure.

By selecting and combining these architectural patterns to match your application’s complexity, performance requirements, and failure tolerance, developers can create multi-agent systems that are both powerful and maintainable. However, successfully implementing these architectures also depends on choosing the right technologies and frameworks that provide essential tools, SDKs, and infrastructure support.

Next, we explore the leading platforms and libraries available today that facilitate the development, deployment, and management of multi-agent applications.

Technologies and Frameworks for Multi-Agent Development

Selecting the right tools and platforms is crucial for building, deploying, and maintaining effective multi-agent systems. Below is an overview of key technologies, SDKs, and integration strategies:

1. Popular Frameworks

• LangChain (and LangGraph): Offers modular chains and agent abstractions for prompt management, with utilities for chaining LLM calls and integrating external data sources. However, it primarily focuses on LLM orchestration and lacks comprehensive native support for autonomous multi-agent collaboration.
• AWS Bedrock & Amazon SageMaker: Managed services offering agent frameworks and scalable compute for training and inference, tightly integrated within the AWS ecosystem. While powerful, they can limit portability and flexibility for multi-cloud or hybrid multi-agent deployments.
• Microsoft Semantic Kernel: SDK for composing AI skills into orchestrated pipelines, enabling conversational agents and background workflows. Though strong in conversational AI, it provides less support for decentralized multi-agent system orchestration.
• Google Vertex AI Agent: Integrates agents with Google Cloud’s data and API ecosystem, providing tooling for stateful workflows and large-scale deployment. Optimized for Google Cloud, it may pose challenges for integration outside this ecosystem or for highly distributed multi-agent setups.

• Rasa & Botpress (for conversational agents): Frameworks for building specialized dialogue agents that can interoperate with other AI or service agents.

3. Containerization & Cloud Infrastructure

• Docker & Kubernetes: Package each agent as a microservice, allowing independent scaling, rolling updates, and resource isolation. Kubernetes operators can manage agent lifecycles and ensure high availability.
• Serverless Platforms: Use AWS Lambda, Azure Functions, or Google Cloud Functions for lightweight agents that respond to events without managing servers.
• Service Meshes: Employ Istio or Linkerd for secure, manageable inter-agent communication, traffic routing, and observability.

4. State, Context, and Memory Management

• Persistent Stores: Use databases (e.g., Redis, DynamoDB) or vector stores (e.g., Pinecone, Weaviate) to retain agent context, conversation history, and learned models across sessions.
• Shared Knowledge Graphs: Maintain a unified graph database (e.g., Neo4j) for agents to read and write structured knowledge, enabling consistent context sharing.
• In-Memory Caches: Employ distributed caches for low-latency state access, letting agents share transient data without repeated API calls.
• Session Management Libraries: Leverage frameworks’ built-in session or memory abstractions (e.g., LangChain’s ConversationBufferMemory) to handle turn-based context tracking automatically.

By combining these frameworks, SDKs, and infrastructure patterns, developers can create modular, scalable, and maintainable multi-agent solutions tailored to enterprise requirements and developer workflows.

Building Multi-Agent Collaboration Workflows

With frameworks and architectural patterns in place, the next step is to orchestrate agents into cohesive workflows. Below is a structured approach followed by a practical DevOps automation example to guide you through designing, implementing, and operating multi-agent systems.

1. Designing Agent Roles and Responsibilities

Begin by identifying discrete capabilities within your domain and assigning them to specialist agents. For a DevOps automation workflow, you might define:

• Pipeline Orchestrator: Oversees end-to-end CI/CD execution, assigns jobs, handles retries.
• Build Agent: Compiles code, runs unit tests, and publishes artifacts.
• Security Agent: Performs static analysis and vulnerability scanning.
• Deployment Agent: Manages environment provisioning and application rollout.
• Notification Agent: Reports status and alerts teams via chat or email.

2. Strategies for Task Decomposition and Assignment

• Centralized Decomposition: The Pipeline Orchestrator breaks a push event into stages (build, test, deploy, notify) and enqueues tasks.
• Dynamic Prioritization: Assign task metadata (e.g., critical, low-priority) so agents can pick high-impact jobs first.
• Fallback Paths: Define alternate flows—if the Security Agent finds critical vulnerabilities, route to a “halt and review” subprocess.

3. Implementing Inter-Agent Messaging and Synchronization

Use a lightweight pub/sub broker for decoupled, asynchronous communication:

python
# Pseudo-code using a pub/sub client
class PipelineOrchestrator:
    def on_push_event(self, commit):
        stages = ["build", "security_scan", "deploy", "notify"]
        for stage in stages:
            pubsub.publish("devops_tasks", {"stage": stage, "commit": commit})

class DevOpsAgent:
    def __init__(self, stage):
        self.stage = stage
        pubsub.subscribe("devops_tasks", self.handle_task)

    def handle_task(self, task):
        if task["stage"] != self.stage: return
        result = getattr(self, f"run_{self.stage}")(task["commit"])
        pubsub.publish("devops_results", {"stage": self.stage, "result": result})

4. Handling Dynamic Task Routing and Failure Scenarios

• Retries & Backoff: Each agent retries transient errors (e.g., network timeouts) with exponential backoff.
• Circuit Breakers: On repeated failures, an agent publishes an error event that the Orchestrator captures to pause further tasks.
• Alternate Flows: If deployment fails, route results to a rollback agent or notify an on-call engineer via the Notification Agent.

5. Monitoring, Logging, and Debugging Multi-Agent Workflows

• Centralized Logging: Agents emit structured logs (agent, task_id, status, duration) to ELK or Datadog.
• Distributed Tracing: Tag each workflow with a unique pipeline_id and propagate it across messages for end-to-end visibility.
• Metrics & Health Checks: Expose Prometheus metrics (tasks_processed, task_failures, avg_latency_ms). Orchestrator auto-scales agents based on queue length and error rates.
• Alerting & Dashboards: Configure alerts for stalled pipelines or high failure rates; build dashboards displaying per-stage performance and bottlenecks.

Practical Example: Multi-Agent DevOps Automation

Below is an end-to-end walkthrough of how agents collaborate to automate a CI/CD pipeline:

python
# 1. Pipeline Orchestrator receives a new commit event
commit = {"id": "abc123", "branch": "main"}
PipelineOrchestrator().on_push_event(commit)
# 2. Build Agent picks up the build task
devops_build = DevOpsAgent("build")
# run_build compiles code and returns artifact URL
# 3. Security Agent scans the artifact
devops_security = DevOpsAgent("security_scan")
# run_security_scan returns pass/fail status
# 4. Deployment Agent handles rollout
devops_deploy = DevOpsAgent("deploy")
# run_deploy uses the artifact URL to deploy to staging/production
# 5. Notification Agent reports back
devops_notify = DevOpsAgent("notify")
# run_notify sends status messages to Slack and email

Interaction Flow:

• Orchestrators publish tasks in sequence.
• Each DevOpsAgent subscribes to a common devops_tasks channel and filters by its stage.
• Upon completion, agents publish results to devops_results, which the Orchestrator aggregates to determine the next steps or trigger alerts.

This modular, message-driven workflow ensures that each agent focuses on a single responsibility, promotes parallel execution, and provides robust mechanisms for error handling and observability key qualities for production-ready multi-agent systems.
