Dynamic Agent Communication System

November 16, 2025 · View on GitHub

Overview

The Dynamic Agent Communication System enables agents to collaborate iteratively on complex tasks through conversational interactions, NOT fire-and-forget messaging. Agents maintain shared context, provide feedback, iterate on solutions, and dynamically allocate work based on capabilities.

Key Concepts

1. Conversational, Not Fire-and-Forget

Traditional multi-agent systems send tasks and forget about them. This system maintains conversation threads where:

  • Agents maintain shared context throughout the conversation
  • Agents can provide feedback on each other's work
  • Tasks can iterate based on feedback (not just succeed/fail)
  • Dependencies between tasks are tracked and enforced
  • The orchestrator monitors the entire conversation state

Example:

# Traditional (fire-and-forget)
send_task_to_agent("CODER", "write authentication")
# ❌ No feedback, no iteration, no context sharing

# Dynamic (conversational)
conversation = create_conversation("Build auth system")
task1 = add_task("Design auth", assigned_to="ARCHITECT")
task2 = add_task("Review design", depends_on=[task1])
# SECURITY reviews, provides feedback
# ARCHITECT iterates on design based on feedback
# ✅ Collaborative, iterative, context-aware

2. Dynamic Task Allocation

Tasks are allocated to agents dynamically based on:

  • Agent capabilities and specialties
  • Current agent load (concurrent tasks)
  • Agent performance history (success rate, response time)
  • Task requirements and priorities

The system automatically selects the best agent for each task.

3. Binary Communication Layer

Messages are translated between human-readable and binary formats:

  • Human-Readable: JSON-like structure for development and debugging
  • Binary: Ultra-fast protocol for production communication (4.2M msg/sec)

Translation is transparent to agents.

4. Feedback Loops

Agents can provide feedback on each other's work, enabling iteration:

ARCHITECT → Design v1
SECURITY → Feedback: "Add rate limiting"
ARCHITECT → Design v2 (incorporating feedback)
SECURITY → Approved

Core Components

Binary Message Translator

Translates between human-readable and binary message formats.

Location: agents/src/python/claude_agents/communication/binary_translator.py

Key Classes:

  • BinaryMessageTranslator: Main translator
  • HumanReadableMessage: Human-readable message format
  • MessageType: Message type enumeration
  • Priority: Priority levels

Example Usage:

from claude_agents.communication.binary_translator import (
    BinaryMessageTranslator,
    HumanReadableMessage,
    MessageType,
    Priority
)

translator = BinaryMessageTranslator()

# Create human-readable message
message = HumanReadableMessage(
    message_id=1,
    message_type=MessageType.TASK.name,
    priority=Priority.HIGH.name,
    source_agent="ORCHESTRATOR",
    target_agents=["DEBUGGER"],
    payload={
        "task_id": 42,
        "action": "analyze_crash",
        "parameters": {"crash_dump": "/tmp/crash.dmp"}
    },
    timestamp=datetime.now(timezone.utc).isoformat()
)

# Convert to binary (for fast transmission)
binary_data = translator.human_to_binary(message)
print(f"Binary size: {len(binary_data)} bytes")

# Convert back to human-readable
decoded = translator.binary_to_human(binary_data)
print(decoded.to_json())

Dynamic Orchestrator

Manages multi-agent conversations with dynamic task allocation.

Location: agents/src/python/claude_agents/communication/dynamic_orchestrator.py

Key Classes:

  • DynamicOrchestrator: Main orchestrator
  • ConversationThread: Conversation state container
  • ConversationTask: Task within a conversation
  • AgentCapability: Agent capability definition

Example Usage:

from claude_agents.communication.dynamic_orchestrator import (
    DynamicOrchestrator,
    TaskState
)

# Create orchestrator
orchestrator = DynamicOrchestrator(enable_binary_communication=True)
await orchestrator.start()

# Register agents with capabilities
orchestrator.register_agent(
    "ARCHITECT",
    capabilities=["system_design", "architecture"],
    specialty_scores={"system_design": 0.95}
)

orchestrator.register_agent(
    "SECURITY",
    capabilities=["security_analysis", "threat_modeling"],
    specialty_scores={"security_analysis": 0.98}
)

# Create conversation
thread_id = orchestrator.create_conversation(
    goal="Design secure authentication system",
    initial_tasks=[
        {
            "description": "Design authentication architecture",
            "priority": "HIGH",
            "context": {
                "required_capabilities": ["system_design"],
                "requirements": ["OAuth2", "JWT", "99.99% uptime"]
            }
        },
        {
            "description": "Security review of design",
            "priority": "CRITICAL",
            "dependencies": [],  # Will be set after first task
            "context": {
                "required_capabilities": ["security_analysis"]
            }
        }
    ]
)

# Set task dependencies
conversation = orchestrator.conversations[thread_id]
task_ids = list(conversation.tasks.keys())
conversation.tasks[task_ids[1]].dependencies = [task_ids[0]]

# Allocate first task (orchestrator picks best agent)
await orchestrator.allocate_task(thread_id, task_ids[0])
# → ARCHITECT is selected based on capabilities

# Simulate task completion
await orchestrator.complete_task(
    thread_id,
    task_ids[0],
    {"design": "OAuth2 + JWT implementation"}
)

# Second task auto-allocates after dependency completes
# → SECURITY is selected for review

# Send feedback
await orchestrator.send_feedback(
    thread_id,
    task_ids[0],
    "SECURITY",
    {
        "action": "revise_design",
        "issues": ["Missing rate limiting"],
        "suggestions": ["Add rate limiter component"]
    }
)
# → ARCHITECT can iterate on design based on feedback

# Get conversation transcript
transcript = orchestrator.get_conversation_transcript(thread_id)
print(transcript)

# Cleanup
await orchestrator.stop()

Conversation Flow Example

Here's a complete example of multi-agent collaboration:

# Goal: Build and deploy a new feature

# 1. Create conversation
thread_id = orchestrator.create_conversation(
    goal="Implement user profile feature",
    initial_tasks=[
        {
            "description": "Design user profile data model",
            "priority": "HIGH",
            "context": {"required_capabilities": ["database_design"]}
        },
        {
            "description": "Security review of data model",
            "priority": "CRITICAL",
            "dependencies": [],  # Will depend on design
            "context": {"required_capabilities": ["security_analysis"]}
        },
        {
            "description": "Implement profile API",
            "priority": "HIGH",
            "dependencies": [],  # Will depend on approved design
            "context": {"required_capabilities": ["api_development"]}
        },
        {
            "description": "Write tests for profile API",
            "priority": "MEDIUM",
            "dependencies": [],  # Will depend on implementation
            "context": {"required_capabilities": ["testing"]}
        }
    ]
)

# 2. Set dependencies
task_ids = get_task_ids(thread_id)
set_dependencies(task_ids[1], depends_on=[task_ids[0]])  # Security review depends on design
set_dependencies(task_ids[2], depends_on=[task_ids[0], task_ids[1]])  # Implementation depends on approved design
set_dependencies(task_ids[3], depends_on=[task_ids[2]])  # Tests depend on implementation

# 3. Start the conversation
# Task 1: DATABASE agent designs data model
await orchestrator.allocate_task(thread_id, task_ids[0])
# → DATABASE agent selected based on database_design capability

# DATABASE completes design
await orchestrator.complete_task(thread_id, task_ids[0], {
    "schema": {
        "users": ["id", "email", "profile_data"],
        "profiles": ["user_id", "bio", "avatar_url"]
    }
})

# Task 2: SECURITY reviews design (auto-allocated after dependency)
# SECURITY finds issue and provides feedback
await orchestrator.send_feedback(
    thread_id, task_ids[0], "SECURITY",
    {
        "action": "revise",
        "issue": "Missing encryption for sensitive profile data",
        "suggestion": "Add field-level encryption for PII"
    }
)

# DATABASE iterates on design
update_task_result(thread_id, task_ids[0], {
    "schema": {
        "users": ["id", "email", "profile_data_encrypted"],
        "profiles": ["user_id", "bio_encrypted", "avatar_url"]
    },
    "encryption": "AES-256-GCM for PII fields"
})

# SECURITY approves
await orchestrator.complete_task(thread_id, task_ids[1], {
    "status": "approved",
    "security_score": 98
})

# Task 3: CONSTRUCTOR implements API (auto-allocated)
# → CONSTRUCTOR selected based on api_development capability
await orchestrator.complete_task(thread_id, task_ids[2], {
    "endpoints": ["/profile", "/profile/:id"],
    "implementation": "complete"
})

# Task 4: TESTBED writes tests (auto-allocated)
# → TESTBED selected based on testing capability
await orchestrator.complete_task(thread_id, task_ids[3], {
    "tests_written": 25,
    "coverage": "95%"
})

# Conversation completes automatically when all tasks done
final_result = get_final_result(thread_id)

Integration with Binary Communication Layer

The system integrates with the existing C/Rust binary communication layer:

Binary Message Format

// C binary format (from agent_protocol.h)
struct ufp_message {
    uint32_t msg_id;
    ufp_msg_type_t msg_type;
    ufp_priority_t priority;
    char source[UFP_AGENT_NAME_SIZE];
    char targets[UFP_MAX_TARGETS][UFP_AGENT_NAME_SIZE];
    uint8_t target_count;
    void* payload;
    size_t payload_size;
    uint32_t timestamp;
    uint32_t correlation_id;
    uint8_t flags;
};

Translation Process

  1. Python creates human-readable message

    message = HumanReadableMessage(...)
    
  2. Translator encodes to binary

    binary_data = translator.human_to_binary(message)
    
  3. Binary layer transmits (4.2M msg/sec)

    ufp_send(ctx, binary_message);
    
  4. Receiver decodes binary

    received_message = translator.binary_to_human(binary_data)
    
  5. Agent processes human-readable format

    process_task(received_message.payload)

Best Practices

1. Define Clear Capabilities

# ✅ Good - specific capabilities
orchestrator.register_agent(
    "DATABASE_EXPERT",
    capabilities=["postgresql", "schema_design", "query_optimization"]
)

# ❌ Bad - vague capabilities
orchestrator.register_agent(
    "GENERAL_AGENT",
    capabilities=["everything"]
)

2. Set Task Dependencies

# ✅ Good - explicit dependencies
task2.dependencies = [task1_id]
task3.dependencies = [task1_id, task2_id]

# ❌ Bad - no dependency tracking
# Tasks may run out of order

3. Use Feedback for Iteration

# ✅ Good - provide actionable feedback
await orchestrator.send_feedback(
    thread_id, task_id, "REVIEWER",
    {
        "action": "revise",
        "specific_issues": ["Missing error handling in line 42"],
        "suggestions": ["Add try/except block"]
    }
)

# ❌ Bad - vague feedback
await orchestrator.send_feedback(
    thread_id, task_id, "REVIEWER",
    {"action": "fix", "comment": "Needs improvement"}
)

4. Include Context in Tasks

# ✅ Good - rich context
{
    "description": "Implement authentication",
    "context": {
        "required_capabilities": ["auth", "security"],
        "requirements": ["OAuth2", "JWT"],
        "constraints": ["<100ms latency"],
        "dependencies_results": {
            "design_task": {...}  # Results from previous tasks
        }
    }
}

Troubleshooting

Issue: Tasks not allocating

Cause: No agent with required capabilities Solution: Register agent with matching capabilities or remove capability requirement

Issue: Feedback not triggering iteration

Cause: Task already at max iterations Solution: Increase max_iterations on task or check iteration count

Issue: Conversation never completes

Cause: Circular task dependencies Solution: Review dependency graph, ensure DAG (directed acyclic graph)

Future Enhancements

  • Agent capability learning (improve specialty scores over time)
  • Parallel task execution within conversation
  • Conversation branching (explore multiple solutions)
  • Agent collaboration patterns (pair programming, code review flows)
  • Integration with existing C coordination layer
  • Distributed conversation support (multi-node)
