SDK for building agents in the Shinox decentralized mesh network

Shinox Agent SDK

A Python library for building agents in the Shinox decentralized mesh network.

Installation

# Using pip
pip install shinox-agent-sdk

# Using uv
uv add shinox-agent-sdk

# With LangChain support
pip install shinox-agent-sdk[langchain]

For local development:

cd shinox-agent-sdk
pip install -e .

Quick Start

Worker Agent (Simple)

For agents that execute tasks and return results:

from shinox_agent import ShinoxWorkerAgent
from brain import brain  # Your LangGraph/LangChain brain
from agent import agent_card  # Your A2A AgentCard

agent = ShinoxWorkerAgent(
    agent_card=agent_card,
    brain=brain,
    triggers=["calculate", "process"],  # Optional custom wake-up words
)

app = agent.app

# Run with: faststream run main:app

The worker automatically:

• Registers with the agent registry
• Joins sessions when invited by Director
• Wakes up when @mentioned or targeted
• Invokes your brain and publishes results

Custom Agent (Advanced)

For agents with complex logic (like Squad Lead):

from shinox_agent import ShinoxAgent, AgentMessage

async def my_handler(msg: AgentMessage, agent: ShinoxAgent):
    headers = msg.headers

    # Custom wake-up logic
    if headers.interaction_type == "SESSION_BRIEFING":
        # Handle briefing
        pass

    if headers.target_agent_id == agent.agent_id:
        # Process and respond
        await agent.publish_message(
            content="Task completed",
            conversation_id=headers.conversation_id,
            interaction_type="TASK_RESULT",
        )

agent = ShinoxAgent(
    agent_card=agent_card,
    session_handler=my_handler,
    triggers=["coordinate", "plan"],
)

app = agent.app

API Reference

ShinoxAgent

Base class for all agents.

ShinoxAgent(
    agent_card: AgentCard,           # A2A agent card
    session_handler: Callable,        # async def handler(msg, agent)
    triggers: list[str] = None,       # Wake-up keywords
    agent_url: str = None,            # URL for registry (default: env AGENT_URL)
)

Attributes:

• agent_id: str - Generated from agent_card.name
• active_sessions: set[str] - Currently joined sessions
• broker: KafkaBroker - FastStream Kafka broker
• app: FastStream - FastStream application

Methods:

• publish_message(content, conversation_id, interaction_type, target_agent_id=None)
• publish_update(content, conversation_id, interaction_type) - Alias for publish_message
• resolve_agent_inbox(agent_id) -> str - Get inbox topic for an agent
• fetch_available_agents(exclude_self=True) -> list[str] - Get active agents from registry

ShinoxWorkerAgent

Worker agent with default wake-up logic.

ShinoxWorkerAgent(
    agent_card: AgentCard,
    brain: Any,                       # LangGraph brain with ainvoke()
    agent_url: str = None,
    triggers: list[str] = None,       # Additional wake-up keywords
)

Additional Methods:

• publish_task_result(content, conversation_id, target_agent_id=None)

Default Wake-up Triggers:

• target_agent_id matches this agent
• @{agent_id} mentioned in content
• Any custom trigger word found (case-insensitive)

Message Schemas

from shinox_agent import AgentMessage, A2AHeaders

# Create a message
msg = AgentMessage(
    content="Hello",
    headers=A2AHeaders(
        source_agent_id="my-agent",
        interaction_type="INFO_UPDATE",
        conversation_id="session.123",
    )
)

Message Flow

1. Director sends JOIN_SESSION to agent inbox
2. Agent joins session, subscribes to session topic, sends acknowledgment
3. Director sends SESSION_BRIEFING to session topic
4. Agent wakes up (if triggered), invokes brain, publishes result
