JAF includes powerful visualization capabilities to help you understand and document your agent systems.

### Prerequisites

First, install the system Graphviz dependency:

```bash
# macOS
brew install graphviz

# Ubuntu/Debian  
sudo apt-get install graphviz

# Windows (via Chocolatey)
choco install graphviz
```

Then install JAF with visualization support:

```bash
pip install "jaf-py[visualization]"
```

### Quick Start

```python
import asyncio
from jaf import Agent, Tool, generate_agent_graph, GraphOptions

# Create your agents
agent = Agent(
    name='MyAgent',
    instructions=lambda state: "I am a helpful assistant.",
    tools=[my_tool],
    handoffs=['OtherAgent']
)

# Generate visualization
async def main():
    result = await generate_agent_graph(
        [agent],
        GraphOptions(
            title="My Agent System",
            output_path="./my-agents.png",
            color_scheme="modern",
            show_tool_details=True
        )
    )
    
    if result.success:
        print(f" Visualization saved to: {result.output_path}")
    else:
        print(f"❌ Error: {result.error}")

asyncio.run(main())
```

### Features

- **Multiple Color Schemes**: Choose from `default`, `modern`, or `minimal` themes
- **Agent Architecture**: Visualize agents, tools, and handoff relationships  
- **Tool Ecosystems**: Generate dedicated tool interaction diagrams
- **Runner Architecture**: Show complete system architecture with session layers
- **Multiple Formats**: Export as PNG, SVG, or PDF
- **Customizable Layouts**: Support for various Graphviz layouts (`dot`, `circo`, `neato`, etc.)

### Example Output

The visualization system generates clear, professional diagrams showing:

- **Agent Nodes**: Rounded rectangles with agent names and model information
- **Tool Nodes**: Ellipses showing tool names and descriptions  
- **Handoff Edges**: Dashed lines indicating agent handoff relationships
- **Tool Connections**: Colored edges connecting agents to their tools
- **Cluster Organization**: Grouped components in runner architecture views

### Advanced Usage

```python
from jaf.visualization import run_visualization_examples

# Run comprehensive examples
await run_visualization_examples()

# This generates multiple example files:
# - ./examples/agent-graph.png (agent system overview)
# - ./examples/tool-graph.png (tool ecosystem)  
# - ./examples/runner-architecture.png (complete system)
# - ./examples/agent-modern.png (modern color scheme)
```

##  Key Components

### Core Types

```python
from dataclasses import dataclass
from pydantic import BaseModel, Field
from jaf import Agent, Tool, RunState, run

# Define your context type
@dataclass
class MyContext:
    user_id: str
    permissions: list[str]

# Define tool schema
class CalculateArgs(BaseModel):
    expression: str = Field(description="Math expression to evaluate")

# Create a tool
class CalculatorTool:
    @property
    def schema(self):
        return type('ToolSchema', (), {
            'name': 'calculate',
            'description': 'Perform mathematical calculations',
            'parameters': CalculateArgs
        })()
    
    async def execute(self, args: CalculateArgs, context: MyContext) -> str:
        result = eval(args.expression)  # Don't do this in production!
        return f"{args.expression} = {result}"

# Define an agent
def create_math_agent():
    def instructions(state):
        return 'You are a helpful math tutor'
    
    return Agent(
        name='MathTutor',
        instructions=instructions,
        tools=[CalculatorTool()]
    )
```

### Running the Framework

```python
import asyncio
from jaf import run, make_litellm_provider, generate_run_id, generate_trace_id
from jaf.core.types import RunState, RunConfig, Message

async def main():
    model_provider = make_litellm_provider('http://localhost:4000')
    math_agent = create_math_agent()
    
    config = RunConfig(
        agent_registry={'MathTutor': math_agent},
        model_provider=model_provider,
        max_turns=10,
        on_event=lambda event: print(event),  # Real-time tracing
    )
    
    initial_state = RunState(
        run_id=generate_run_id(),
        trace_id=generate_trace_id(),
        messages=[Message(role='user', content='What is 2 + 2?')],
        current_agent_name='MathTutor',
        context=MyContext(user_id='user123', permissions=['user']),
        turn_count=0,
    )
    
    result = await run(initial_state, config)
    print(result.outcome.output if result.outcome.status == 'completed' else result.outcome.error)

asyncio.run(main())
```

##  Security & Validation

### Composable Validation Policies

```python
from jaf.policies.validation import create_path_validator, create_permission_validator, compose_validations

# Create individual validators
path_validator = create_path_validator(['/shared', '/public'])
permission_validator = create_permission_validator('admin', lambda ctx: ctx)

# Compose them
combined_validator = compose_validations(path_validator, permission_validator)

# Apply to tools
secure_file_tool = with_validation(base_file_tool, combined_validator)
```

### Guardrails

```python
from jaf.policies.validation import create_content_filter, create_length_guardrail

config = RunConfig(
    # ... other config
    initial_input_guardrails=[
        create_content_filter(['spam', 'inappropriate']),  # Requires blocked patterns
        create_length_guardrail(max_length=1000, min_length=1)
    ],
    final_output_guardrails=[
        create_content_filter(['harmful', 'unsafe'])
    ],
)
```

##  Agent-as-Tool Functionality

JAF 2.2+ introduces powerful agent-as-tool capabilities, allowing you to use agents as tools within other agents for hierarchical orchestration:

```python
from jaf.core.agent_tool import create_agent_tool
from jaf.core.types import create_json_output_extractor

# Create specialized agents
spanish_agent = Agent(
    name="spanish_translator",
    instructions=lambda state: "Translate text to Spanish",
    output_codec=TranslationOutput
)

french_agent = Agent(
    name="french_translator", 
    instructions=lambda state: "Translate text to French",
    output_codec=TranslationOutput
)

# Convert agents to tools with conditional enabling
spanish_tool = spanish_agent.as_tool(
    tool_name="translate_to_spanish",
    tool_description="Translate text to Spanish",
    max_turns=3,
    custom_output_extractor=create_json_output_extractor(),
    is_enabled=True  # Always enabled
)

french_tool = french_agent.as_tool(
    tool_name="translate_to_french", 
    tool_description="Translate text to French",
    max_turns=3,
    custom_output_extractor=create_json_output_extractor(),
    is_enabled=lambda context, agent: context.language_preference == "french_spanish"
)

# Create orchestrator agent using agent tools
orchestrator = Agent(
    name="translation_orchestrator",
    instructions=lambda state: "Use translation tools to respond in multiple languages",
    tools=[spanish_tool, french_tool]
)
```

### Key Features:
- **Conditional Enabling**: Enable/disable agent tools based on runtime context
- **Session Management**: Configure whether sub-agents inherit parent session state
- **Custom Output Extraction**: Define how to extract and format agent tool outputs
- **Error Handling**: Robust error handling for failed agent tool executions

## 🔗 Agent Handoffs

```python
from jaf.policies.handoff import create_handoff_guardrail, HandoffPolicy
from pydantic import BaseModel
from enum import Enum

class AgentName(str, Enum):
    MATH_TUTOR = 'MathTutor'
    FILE_MANAGER = 'FileManager'

class HandoffOutput(BaseModel):
    agent_name: AgentName

def create_triage_agent():
    def instructions(state):
        return 'Route requests to specialized agents'
    
    return Agent(
        name='TriageAgent',
        instructions=instructions,
        tools=[],  # Regular tools would go here
        handoffs=['MathTutor', 'FileManager'],  # Allowed handoff targets
        output_schema=HandoffOutput,
    )
```

##  Observability

### Real-time Tracing

```python
from jaf.core.tracing import ConsoleTraceCollector, FileTraceCollector, create_composite_trace_collector

# Console logging
console_tracer = ConsoleTraceCollector()

# File logging
file_tracer = FileTraceCollector('./traces.log')

# Composite tracing
tracer = create_composite_trace_collector(console_tracer, file_tracer)

config = RunConfig(
    # ... other config
    on_event=tracer.collect,
)
```

### OpenTelemetry Integration

JAF 2.2+ includes built-in OpenTelemetry support for distributed tracing:

```python
import os
from jaf.core.tracing import create_composite_trace_collector, ConsoleTraceCollector

# Configure OpenTelemetry endpoint
os.environ["TRACE_COLLECTOR_URL"] = "http://localhost:4318/v1/traces"

# Tracing will be automatically configured when creating a composite collector
trace_collector = create_composite_trace_collector(ConsoleTraceCollector())

config = RunConfig(
    # ... other config
    on_event=trace_collector.collect,
)
```

### Langfuse Integration

For LLM-specific observability and analytics:

```python
import os
from jaf.core.tracing import create_composite_trace_collector, ConsoleTraceCollector

# Configure Langfuse credentials
os.environ["LANGFUSE_PUBLIC_KEY"] = "pk-lf-your-public-key"
os.environ["LANGFUSE_SECRET_KEY"] = "sk-lf-your-secret-key" 
os.environ["LANGFUSE_HOST"] = "https://cloud.langfuse.com"  # or your self-hosted instance

# Langfuse tracing will be automatically configured
trace_collector = create_composite_trace_collector(ConsoleTraceCollector())

config = RunConfig(
    # ... other config
    on_event=trace_collector.collect,
)
```

### Error Handling

```python
from jaf.core.errors import JAFErrorHandler

if result.outcome.status == 'error':
    formatted_error = JAFErrorHandler.format_error(result.outcome.error)
    is_retryable = JAFErrorHandler.is_retryable(result.outcome.error)
    severity = JAFErrorHandler.get_severity(result.outcome.error)
    
    print(f"[{severity}] {formatted_error} (retryable: {is_retryable})")
```

##  Provider Integrations

### A2A (Agent-to-Agent) Communication

JAF provides a robust A2A communication layer that allows agents to interact with each other. This is useful for building multi-agent systems where different agents have specialized skills.

```python
from jaf.a2a import create_a2a_agent, create_a2a_client, create_a2a_server

# Create agents
echo_agent = create_a2a_agent("EchoBot", "Echoes messages", "You are an echo bot.", [])
ping_agent = create_a2a_agent("PingBot", "Responds to pings", "You are a ping bot.", [])

# Create a server
server_config = {
    "agents": {"EchoBot": echo_agent, "PingBot": ping_agent},
    "agentCard": {"name": "Test Server"},
    "port": 8080,
}
server = create_a2a_server(server_config)

# Create a client
client = create_a2a_client("http://localhost:8080")
```

### LiteLLM Provider

```python
from jaf.providers.model import make_litellm_provider

# Connect to LiteLLM proxy for 100+ model support
model_provider = make_litellm_provider(
    'http://localhost:4000',  # LiteLLM proxy URL
    'your-api-key'           # Optional API key
)
```

### MCP (Model Context Protocol) Integration

JAF includes full Model Context Protocol support for seamless tool integration:

```python
from jaf.providers.mcp import create_mcp_stdio_client, create_mcp_tools_from_client

# Connect to MCP server via stdio
mcp_client = create_mcp_stdio_client(['python', '-m', 'my_mcp_server'])

# Initialize and get all available tools
await mcp_client.initialize()
mcp_tools = await create_mcp_tools_from_client(mcp_client)

# Use MCP tools in your agent
def create_mcp_agent():
    def instructions(state):
        return "You have access to powerful MCP tools for various tasks."
    
    return Agent(
        name='MCPAgent',
        instructions=instructions,
        tools=mcp_tools  # Automatically converted JAF tools
    )

# SSE client is also supported
from jaf.providers.mcp import create_mcp_sse_client
sse_client = create_mcp_sse_client('http://localhost:8080/sse')
```

##  Development Server

JAF includes a built-in development server for testing agents locally via HTTP endpoints:

```python
from jaf.server import run_server
from jaf.providers.model import make_litellm_provider

def create_my_agent():
    def instructions(state):
        return 'You are a helpful assistant'
    
    return Agent(
        name='MyAgent',
        instructions=instructions,
        tools=[calculator_tool, greeting_tool]
    )

model_provider = make_litellm_provider('http://localhost:4000')

# Start server on port 3000
await run_server(
    [create_my_agent()], 
    {'model_provider': model_provider},
    {'port': 3000}
)
```

Server provides RESTful endpoints:
- `GET /health` - Health check
- `GET /agents` - List available agents  
- `POST /chat` - General chat endpoint
- `POST /agents/{name}/chat` - Agent-specific endpoint

##  Function Composition

JAF supports functional composition patterns for building complex behaviors from simple, reusable functions:

```python
from jaf import create_function_tool, ToolSource

# Enhanced tool with caching and retry
def with_cache(tool_func):
    cache = {}
    async def cached_execute(args, context):
        cache_key = str(args)
        if cache_key in cache:
            return cache[cache_key]
        result = await tool_func(args, context)
        if result.status == "success":
            cache[cache_key] = result
        return result
    return cached_execute

# Create enhanced tools by composition
enhanced_tool = create_function_tool({
    'name': 'enhanced_search',
    'description': 'Search with caching',
    'execute': with_cache(base_search_function),
    'parameters': SearchArgs,
    'source': ToolSource.NATIVE
})
```

**Key Benefits:**
- **Reusability**: Write once, compose everywhere
- **Testability**: Each function can be tested in isolation  
- **Type Safety**: Full type checking support
- **Performance**: Optimize individual pieces independently

```

##  Architecture Principles

### Immutable State Machine
- All state transformations create new state objects
- No mutation of existing data structures
- Predictable, testable state transitions

### Type Safety
- Runtime validation with Pydantic schemas
- Compile-time safety with Python type hints
- NewType for type-safe identifiers

### Pure Functions
- Core logic is side-effect free
- Easy to test and reason about
- Deterministic behavior

### Effect Isolation
- Side effects only in Provider modules
- Clear boundaries between pure and impure code
- Easier mocking and testing
