Agent Transparency

A comprehensive Python library for tracking the input, thought process, and output of AI agents. Provides extreme transparency into agent behavior for debugging, auditing, and understanding agent decisions.

Features

• Comprehensive Event Tracking: Log inputs, thinking processes, LLM calls, graph executions, outputs, and errors
• Multiple Output Destinations: Write to files (JSONL), console, or Kafka streams
• LangGraph Integration: Built-in support for tracking LangGraph node executions and state transitions
• Async & Sync APIs: Both asynchronous and synchronous interfaces for flexibility
• Context Management: Track related events across sessions and conversations
• Real-time Viewer: Optional web-based viewer for monitoring agent activity in real-time
• Lightweight: Minimal dependencies for core functionality
• Type-Safe: Full type hints and dataclass-based event structures

Usage Examples

LangGraph Integration

from transparency import TransparencyManager, LangGraphNodeType

transparency = TransparencyManager(agent_id="langgraph-agent")
await transparency.start()

# Track graph execution
await transparency.log_graph_invoke_start(initial_state={"messages": []})

# Track node execution
await transparency.log_node_enter(
    node_name="planner",
    node_type=LangGraphNodeType.PLANNER,
    state_before=state
)

# Use context manager for automatic entry/exit tracking
async with transparency.trace_node("executor", LangGraphNodeType.EXECUTOR, state):
    # Your node logic here
    result = await execute_plan()

await transparency.log_graph_invoke_end(final_state=state)

LLM Call Tracking

# Manual tracking
await transparency.log_llm_request_start(
    model_name="gpt-4",
    prompt="Analyze this data",
    system_prompt="You are a data analyst"
)

response = await llm.generate(prompt)

await transparency.log_llm_response(
    model_name="gpt-4",
    prompt="Analyze this data",
    response=response.text,
    input_tokens=response.usage.input_tokens,
    output_tokens=response.usage.output_tokens,
    latency_ms=response.latency
)

# Or use context manager
async with transparency.trace_llm_call("gpt-4", prompt) as ctx:
    response = await llm.generate(prompt)
    ctx["response"] = response.text

Context Management

# Create a context for tracking related events
context = transparency.create_context(
    session_id="session-123",
    conversation_id="conv-456"
)
transparency.set_context(context)

# All subsequent events will include this context
await transparency.log_input_received("Hello")

# Or use context manager
async with transparency.context_scope(session_id="session-123"):
    await transparency.log_input_received("Hello")
    await transparency.log_thinking_step(...)
    # Context automatically restored after block

Thinking Process Tracking

# Track detailed reasoning
await transparency.log_thinking_start("Processing user request")

await transparency.log_thinking_step(
    phase=ThinkingPhase.PERCEPTION,
    description="Understanding user intent",
    reasoning="User is asking about weather conditions"
)

await transparency.log_thinking_step(
    phase=ThinkingPhase.PLANNING,
    description="Planning data retrieval",
    considerations=[
        "Need user location",
        "Check weather API availability",
        "Format response appropriately"
    ]
)

await transparency.log_thinking_decision(
    decision="Fetch weather data from OpenWeatherMap API",
    rationale="Most reliable source with current conditions",
    alternatives=[
        {"option": "Weather.gov", "reason_rejected": "Limited coverage"},
        {"option": "AccuWeather", "reason_rejected": "Requires premium API"}
    ],
    confidence=0.95
)

await transparency.log_thinking_end("Request processing complete")

Error Tracking

try:
    result = await risky_operation()
except Exception as e:
    await transparency.log_error(
        error_type="APIError",
        message=str(e),
        exception=e,
        context={"operation": "weather_fetch", "retry_count": 3},
        recoverable=True
    )

Synchronous Usage

from transparency import SyncTransparencyManager

# Wrap async manager for sync contexts (like LangGraph nodes)
async_manager = TransparencyManager(agent_id="sync-agent")
sync_transparency = SyncTransparencyManager(async_manager)

# Use in synchronous functions
def my_langgraph_node(state):
    sync_transparency.log_node_enter("my_node", LangGraphNodeType.CUSTOM, state)

    # Do work...

    sync_transparency.log_node_exit("my_node", LangGraphNodeType.CUSTOM, state, new_state)
    return new_state

Configuration

Output Destinations

from transparency import TransparencyConfig, OutputDestination

config = TransparencyConfig(
    enabled=True,
    destinations=[
        OutputDestination.FILE,
        OutputDestination.CONSOLE,
        OutputDestination.KAFKA
    ],

    # File settings
    file_path="./transparency_logs",

    # Kafka settings (requires aiokafka)
    kafka_topic="agent.transparency",
    kafka_broker=kafka_broker_instance,

    # Filtering
    min_severity=Severity.DEBUG,
    event_type_filter=[],  # Empty = all events

    # Performance
    buffer_size=100,
    flush_interval_seconds=1.0,
    async_mode=True,

    # Formatting
    pretty_print=True,
    include_stack_traces=True
)

transparency = TransparencyManager(agent_id="my-agent", config=config)

Severity Levels

Events are logged with severity levels for filtering:

• TRACE - Finest-grained debugging
• DEBUG - Detailed diagnostic information
• INFO - General informational messages
• WARNING - Warning messages
• ERROR - Error events
• CRITICAL - Critical failures

# Only log INFO and above
config.min_severity = Severity.INFO

Real-time Viewer

The library includes an optional web-based viewer for monitoring agent activity in real-time.

Starting the Viewer

# Watch a log file
transparency-viewer --log-path ./logs/my-agent_transparency.jsonl

# Or from Kafka
transparency-viewer --kafka-bootstrap localhost:9092 --kafka-topic agent.my-agent.transparency

# Custom port
transparency-viewer --log-path ./logs/my-agent_transparency.jsonl --port 8080

Then open http://localhost:8765 in your browser.

Programmatic Usage

from viewer.viewer_server import TransparencyViewerServer, ServerConfig, SourceType

# File-based viewer
config = ServerConfig(
    port=8765,
    source_type=SourceType.FILE,
    log_path="./logs/agent_transparency.jsonl"
)

server = TransparencyViewerServer(config)
await server.start()

# Keep running
await asyncio.Event().wait()

Output Format

Events are logged in JSONL format (newline-delimited JSON):

{
  "event_type": "thinking.step",
  "metadata": {
    "event_id": "550e8400-e29b-41d4-a716-446655440000",
    "timestamp": "2024-01-10T15:30:45.123456Z",
    "agent_id": "my-agent",
    "session_id": "session-123",
    "conversation_id": "conv-456",
    "sequence_number": 42,
    "severity": "debug",
    "tags": ["thinking", "analysis"]
  },
  "payload": {
    "phase": "analysis",
    "description": "Analyzing user request",
    "reasoning": "User wants weather information",
    "considerations": ["Location needed", "API selection"],
    "confidence_score": 0.95
  }
}

Best Practices

1. Start/Stop the Manager: Always call start() and stop() to ensure proper buffering and flushing
2. Use Context Managers: Leverage trace_node(), trace_llm_call(), and context_scope() for automatic tracking
3. Set Contexts: Use session and conversation IDs to correlate related events
4. Filter Appropriately: Set min_severity and event_type_filter in production to reduce overhead
5. Async Mode: Keep async_mode=True for better performance in high-throughput scenarios
6. Monitor Buffer Size: Adjust buffer_size based on event volume

Requirements
