+ version: 1.0.0
+ description: "Agent for analyzing email threads"
+agent:
+ name: EmailSummaryAgent
+ role: Email communication expert
+ model:
+ provider: openai
+ name: gpt-4o-mini
+ settings:
+ temperature: 0
+ max_retries: 3
+ reasoning_pattern: DIRECT
+ job: >
+ You are given an email thread between a customer and a support agent.
+ Your job is to analyze the behavior, sentiment, and communication style.
+ parser:
+ name: EmailSummary
+ fields:
+ - name: sender_type
+ type: literal
+ description: "Who sent the latest email"
+ values:
+ - value: customer
+ description: "Latest email was sent by customer"
+ - value: agent
+ description: "Latest email was sent by support agent"
+ - name: summary

+ type: literal
+ description: "Issue resolution status"
+ values:
+ - value: resolved
+ description: "Issue appears resolved"
+ - value: unresolved
+ description: "Issue requires attention"
+```
+
+```python
+from typing import Any, List
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.models.agent import Agent
+
+# Create agent from YAML
+yaml_config: str = """...""" # Your YAML configuration string
+email_thread: List[str] = ["Email thread content..."]
+
+builder: AgentBuilder = AgentBuilder.from_yaml(yaml_str=yaml_config)
+agent: Agent = builder.build()
+
+# Use the agent
+result: Any = await agent.run(email_thread)
+```
+
+## π§ Variables System
+
+Flo AI supports dynamic variable resolution in agent prompts and inputs using `` syntax. Variables are automatically discovered, validated at runtime, and can be shared across multi-agent workflows.
+
+### β¨ Key Features
+
+- **π Automatic Discovery**: Variables are extracted from system prompts and inputs at runtime
+- **β
Runtime Validation**: Missing variables are reported with detailed error messages
+- **π€ Multi-Agent Support**: Variables can be shared across agent workflows
+- **π‘οΈ JSON-Safe Syntax**: `` format avoids conflicts with JSON content
+
+### Basic Usage
+
+```python
+import asyncio
+from typing import Any, Dict
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.agent import Agent
+
+async def main() -> None:
+ # Create agent with variables in system prompt
+ agent: Agent = (
+ AgentBuilder()
+ .with_name('Data Analyst')
+ .with_prompt('Analyze and focus on . Generate insights for .')
+ .with_llm(OpenAI(model='gpt-4o-mini'))
+ .build()
+ )
+
+ # Define variables at runtime
+ variables: Dict[str, str] = {
+ 'dataset_path': '/data/sales_q4_2024.csv',
+ 'key_metric': 'revenue growth',
+ 'target_audience': 'executive team'
+ }
+
+ # Run agent with variable resolution
+ result: Any = await agent.run(
+ 'Please provide a comprehensive analysis with actionable recommendations.',
+ variables=variables
+ )
+
+ print(f'Analysis: {result}')
+
+asyncio.run(main())
+```
+
+### Variables in User Input
+
+Variables can also be used in the user input messages:
+
+```python
+import asyncio
+from typing import Any, Dict
+from flo_ai.models.agent import Agent
+from flo_ai.llm import OpenAI
+
+async def input_variables_example() -> None:
+ agent: Agent = Agent(
+ name='content_creator',
+ system_prompt='You are a content creator specializing in .',
+ llm=OpenAI(model='gpt-4o-mini')
+ )
+
+ variables: Dict[str, str] = {
+ 'content_type': 'technical blog posts',
+ 'topic': 'machine learning fundamentals',
+ 'word_count': '1500',
+ 'target_level': 'intermediate'
+ }
+
+ # Variables in both system prompt and user input
+ result: Any = await agent.run(
+ 'Create a -word article about for readers.',
+ variables=variables
+ )
+
+ print(f'Content: {result}')
+
+asyncio.run(input_variables_example())
+```
+
+### Multi-Agent Variable Sharing
+
+Variables can be shared and passed between agents in workflows:
+
+```python
+import asyncio
+from typing import Any, Dict, List
+from flo_ai.arium import AriumBuilder
+from flo_ai.models.agent import Agent
+from flo_ai.llm import OpenAI
+
+async def multi_agent_variables() -> List[Any]:
+ llm: OpenAI = OpenAI(model='gpt-4o-mini')
+
+ # Agent 1: Research phase
+ researcher: Agent = Agent(
+ name='researcher',
+ system_prompt='Research and focus on analysis.',
+ llm=llm
+ )
+
+ # Agent 2: Writing phase
+ writer: Agent = Agent(
+ name='writer',
+ system_prompt='Write a based on the research for .',
+ llm=llm
+ )
+
+ # Agent 3: Review phase
+ reviewer: Agent = Agent(
+ name='reviewer',
+ system_prompt='Review the for and provide feedback.',
+ llm=llm
+ )
+
+ # Shared variables across all agents
+ shared_variables: Dict[str, str] = {
+ 'research_topic': 'sustainable energy solutions',
+ 'research_depth': 'comprehensive',
+ 'document_type': 'white paper',
+ 'target_audience': 'policy makers',
+ 'review_criteria': 'accuracy and policy relevance'
+ }
+
+ # Run multi-agent workflow with shared variables
+ result: List[Any] = await (
+ AriumBuilder()
+ .add_agents([researcher, writer, reviewer])
+ .start_with(researcher)
+ .connect(researcher, writer)
+ .connect(writer, reviewer)
+ .end_with(reviewer)
+ .build_and_run(
+ ['Begin comprehensive research and document creation process'],
+ variables=shared_variables
+ )
+ )
+
+ return result
+
+asyncio.run(multi_agent_variables())
+```
+
+### YAML Configuration with Variables
+
+Variables work seamlessly with YAML-based agent configuration:
+
+```yaml
+metadata:
+ name: personalized-assistant
+ version: 1.0.0
+ description: "Personalized assistant with variable support"
+agent:
+ name: PersonalizedAssistant
+ kind: llm
+ role: assistant specialized in
+ model:
+ provider: openai
+ name: gpt-4o-mini
+ settings:
+ temperature: 0.3
+ max_retries: 2
+ reasoning_pattern: DIRECT
+ job: >
+ You are a focused on .
+ Your expertise includes and you should
+ tailor responses for users.
+ Always consider in your recommendations.
+```
+
+```python
+import asyncio
+from typing import Any, Dict
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.models.agent import Agent
+
+async def yaml_with_variables() -> None:
+ yaml_config: str = """...""" # Your YAML configuration
+
+ # Variables for YAML agent
+ variables: Dict[str, str] = {
+ 'user_role': 'data scientist',
+ 'domain_expertise': 'machine learning and statistical analysis',
+ 'primary_objective': 'deriving actionable insights from data',
+ 'experience_level': 'senior',
+ 'priority_constraints': 'computational efficiency and model interpretability'
+ }
+
+ # Create agent from YAML with variables
+ builder: AgentBuilder = AgentBuilder.from_yaml(yaml_str=yaml_config)
+ agent: Agent = builder.build()
+
+ result: Any = await agent.run(
+ 'Help me design an ML pipeline for with ',
+ variables={
+ **variables,
+ 'use_case': 'customer churn prediction',
+ 'data_constraints': 'limited labeled data'
+ }
+ )
+
+ print(f'ML Pipeline Advice: {result}')
+
+asyncio.run(yaml_with_variables())
+```
+
+### Error Handling and Validation
+
+The variables system provides comprehensive error reporting for missing or invalid variables:
+
+```python
+import asyncio
+from typing import Any, Dict
+from flo_ai.models.agent import Agent
+from flo_ai.llm import OpenAI
+
+async def variable_validation_example() -> None:
+ agent: Agent = Agent(
+ name='validator_example',
+ system_prompt='Process and for analysis.',
+ llm=OpenAI(model='gpt-4o-mini')
+ )
+
+ # Incomplete variables (missing 'another_param')
+ incomplete_variables: Dict[str, str] = {
+ 'required_param': 'dataset.csv'
+ # 'another_param' is missing
+ }
+
+ try:
+ result: Any = await agent.run(
+ 'Analyze the data in ',
+ variables=incomplete_variables # Missing 'another_param' and 'data_source'
+ )
+ except ValueError as e:
+ print(f'Variable validation error: {e}')
+ # Error will list all missing variables with their locations
+
+asyncio.run(variable_validation_example())
+```
+
+### Best Practices
+
+1. **Descriptive Variable Names**: Use clear, descriptive names like `` instead of ``
+2. **Consistent Naming**: Use consistent variable names across related agents and workflows
+3. **Validation**: Always test your variable resolution before production deployment
+4. **Documentation**: Document expected variables in your agent configurations
+
+The variables system makes Flo AI agents highly reusable and configurable, enabling you to create flexible AI workflows that adapt to different contexts and requirements.
+
+## π Document Processing
+

+- **π Rich Metadata**: Extract page counts, processing methods, and document statistics
+
+### Basic Document Processing
+
+```python
+import asyncio
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.document import DocumentMessage, DocumentType
+
+async def basic_document_analysis():
+ # Create document message from file path
+ document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_file_path='path/to/your/document.pdf'
+ )
+
+ # Create document analysis agent
+ agent = (
+ AgentBuilder()
+ .with_name('Document Analyzer')
+ .with_prompt('Analyze the provided document and extract key insights, themes, and important information.')
+ .with_llm(OpenAI(model='gpt-4o-mini'))
+ .build()
+ )
+
+ # Process document with agent
+ result = await agent.run([document])
+ print(f'Analysis: {result}')
+
+asyncio.run(basic_document_analysis())
+```
+
+### Multiple Input Methods
+
+Flo AI supports three ways to provide document content:
+
+#### 1. File Path (Recommended)
+```python
+document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_file_path='/path/to/document.pdf'
+)
+```
+
+#### 2. Bytes Data
+```python
+# Read file as bytes
+with open('document.pdf', 'rb') as f:
+ pdf_bytes = f.read()
+
+document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_bytes=pdf_bytes,
+ mime_type='application/pdf'
+)
+```
+
+#### 3. Base64 Encoded
+```python
+import base64
+
+# Encode file to base64
+with open('document.pdf', 'rb') as f:
+ pdf_base64 = base64.b64encode(f.read()).decode('utf-8')
+
+document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_base64=pdf_base64,
+ mime_type='application/pdf'

+
+async def document_workflow():
+ # Create document message
+ document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_file_path='business_report.pdf'
+ )
+
+ # Define workflow YAML
+ workflow_yaml = """

+
+#### Processing Different Document Types
+```python
+# PDF Document
+pdf_doc = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_file_path='presentation.pdf'
+)
+
+# Text Document
+txt_doc = DocumentMessage(
+ document_type=DocumentType.TXT,
+ document_file_path='notes.txt'
+)
+
+# Process both with the same agent
+agent = AgentBuilder().with_name('Multi-Format Analyzer').build()
+
+pdf_result = await agent.run([pdf_doc])
+txt_result = await agent.run([txt_doc])
+```
+
+### Document Processing Tools
+
+Create custom tools for document operations:
+
+```python
+from flo_ai.tool import flo_tool
+from flo_ai.models.document import DocumentMessage, DocumentType
+
+@flo_tool(description="Extract key information from documents")
+async def extract_document_info(document_path: str, doc_type: str) -> str:
+ """Extract key information from a document."""
+ document_type = DocumentType.PDF if doc_type.lower() == 'pdf' else DocumentType.TXT
+
+ document = DocumentMessage(
+ document_type=document_type,
+ document_file_path=document_path
+ )
+
+ # Use document processing agent
+ agent = AgentBuilder().with_name('Info Extractor').build()
+ result = await agent.run([document])
+
+ return result
+
+# Use in agent
+agent = (
+ AgentBuilder()
+ .with_name('Document Processor')
+ .with_tools([extract_document_info.tool])
+ .build()
+)
+```
+
+### Error Handling
+
+```python
+from flo_ai.utils.document_processor import DocumentProcessingError
+
+try:
+ document = DocumentMessage(
+ document_type=DocumentType.PDF,
+ document_file_path='nonexistent.pdf'
+ )
+ result = await agent.run([document])
+except DocumentProcessingError as e:
+ print(f'Document processing failed: {e}')
+except FileNotFoundError:
+ print('Document file not found')
+```
+
+### Supported Document Types
+
+| Type | Extension | Description | Processing Method |
+|------|-----------|-------------|-------------------|
+| PDF | `.pdf` | Portable Document Format | PyMuPDF4LLM (LLM-optimized) |
+| TXT | `.txt` | Plain text files | UTF-8 with encoding detection |
+
+### Best Practices
+
+1. **File Validation**: Always check if files exist before processing
+2. **Memory Management**: Use file paths for large documents to avoid memory issues
+3. **Error Handling**: Implement proper error handling for document processing failures
+4. **Metadata**: Add relevant metadata to help agents understand document context
+5. **Format Selection**: Choose the most appropriate input method for your use case
+
+### Use Cases
+
+- π **Document Analysis**: Extract insights from reports, papers, and documents
+- π **Content Summarization**: Create summaries of long documents
+- π **Information Extraction**: Pull specific data from structured documents
+- π **Document Classification**: Categorize documents based on content
+- π€ **Multi-Agent Workflows**: Process documents through specialized agent pipelines
+- π **Business Intelligence**: Analyze business documents for insights and trends
+
+The document processing system makes Flo AI incredibly powerful for real-world applications that need to work with various document formats, enabling sophisticated AI workflows that can understand and process complex document content.
+
+## π οΈ Tools
+
+Create custom tools easily with async support:
+
+```python
+from typing import List
+from flo_ai.tool.base_tool import Tool
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.agent import Agent
+
+async def weather_lookup(city: str) -> str:
+ # Your weather API call here
+ return f"Weather in {city}: Sunny, 25Β°C"
+
+weather_tool: Tool = Tool(
+ name='weather_lookup',
+ description='Get current weather for a city',
+ function=weather_lookup,
+ parameters={
+ 'city': {
+ 'type': 'string',
+ 'description': 'City name to get weather for'
+ }
+ }
+)
+
+# Add to your agent
+agent: Agent = (
+ AgentBuilder()
+ .with_name('Weather Assistant')
+ .with_llm(OpenAI(model='gpt-4o-mini'))
+ .with_tools([weather_tool])
+ .build()
+)
+```
+
+### π― @flo_tool Decorator
+
+The `@flo_tool` decorator automatically converts any Python function into a `Tool` object with minimal boilerplate:
+
+```python
+from typing import Any, Dict, Union
+from flo_ai.tool import flo_tool
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.agent import Agent
+
+@flo_tool(
+ description="Perform mathematical calculations",
+ parameter_descriptions={
+ "operation": "The operation to perform (add, subtract, multiply, divide)",
+ "x": "First number",
+ "y": "Second number"
+ }
+)
+async def calculate(operation: str, x: float, y: float) -> Union[float, str]:
+ """Calculate mathematical operations between two numbers."""
+ operations: Dict[str, callable] = {
+ 'add': lambda: x + y,
+ 'subtract': lambda: x - y,
+ 'multiply': lambda: x * y,
+ 'divide': lambda: x / y if y != 0 else 'Cannot divide by zero',
+ }
+ if operation not in operations:
+ raise ValueError(f'Unknown operation: {operation}')
+ return operations[operation]()
+
+# Function can be called normally
+result: Union[float, str] = await calculate("add", 5, 3) # Returns 8
+
+# Tool object is automatically available
+agent: Agent = (
+ AgentBuilder()
+ .with_name('Calculator Agent')
+ .with_llm(OpenAI(model='gpt-4o-mini'))
+ .with_tools([calculate.tool]) # Access the tool via .tool attribute
+ .build()
+)
+```
+
+**Key Benefits:**
+- β
**Automatic parameter extraction** from type hints
+- β
**Flexible descriptions** via docstrings or custom descriptions
+- β
**Type conversion** from Python types to JSON schema
+- β
**Dual functionality** - functions work normally AND as tools
+- β
**Async support** for both sync and async functions
+
+**Simple Usage:**
+```python
+from flo_ai.tool import flo_tool
+
+@flo_tool()
+async def convert_units(value: float, from_unit: str, to_unit: str) -> str:
+ """Convert between different units (km/miles, kg/lbs, celsius/fahrenheit)."""
+ # Implementation here
+ result: float = 0.0 # Your conversion logic here
+ return f"{value} {from_unit} = {result} {to_unit}"
+
+# Tool is automatically available as convert_units.tool
+```
+
+**With Custom Metadata:**
+```python
+from typing import Optional
+from flo_ai.tool import flo_tool
+
+@flo_tool(
+ name="weather_checker",
+ description="Get current weather information for a city",
+ parameter_descriptions={
+ "city": "The city to get weather for",
+ "country": "The country (optional)",
+ }
+)
+async def get_weather(city: str, country: Optional[str] = None) -> str:
+ """Get weather information for a specific city."""
+ return f"Weather in {city}: sunny"
+```
+
+> π **For detailed documentation on the `@flo_tool` decorator, see [README_flo_tool.md](TOOLS.md)**
+
+## π§ Reasoning Patterns
+
+Flo AI supports multiple reasoning patterns:
+
+- **DIRECT**: Simple question-answer without step-by-step reasoning
+- **COT (Chain of Thought)**: Step-by-step reasoning before providing the answer
+- **REACT**: Reasoning and action cycles for tool-using agents
+
+```python
+from flo_ai.models.base_agent import ReasoningPattern
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.agent import Agent
+
+agent: Agent = (
+ AgentBuilder()
+ .with_name('Reasoning Agent')
+ .with_llm(OpenAI(model='gpt-4o'))
+ .with_reasoning(ReasoningPattern.COT) # or REACT, DIRECT
+ .build()
+)
+```
+
+## π§ LLM Providers
+
+### OpenAI
+```python
+from flo_ai.llm import OpenAI
+
+llm: OpenAI = OpenAI(

+
+llm: Ollama = Ollama(
+ model='llama2',
+ base_url='http://localhost:11434'
+)
+```
+
+### Streaming Support in LLM
+Streaming helps the llm to generate the output (response) piece-by-piece, or token-by-token,
+as it is being computed, instead of waiting until the entire response is complete before sending it to the user
+
+Steaming Support has been added to all the llm providers. Example of streaming function with Gemini is shown below:
+```python
+from flo_ai.llm import Gemini
+
+llm: Gemini = Gemini(
+ model='gemini-2.5-flash', # or gemini-2.5-pro
+ temperature=0.7,
+ api_key='your-api-key' # or set GOOGLE_API_KEY env var
+)
+messages=[{"role": "user", "content": "Stream a short sentence."}]
+chunks: List[str] = []
+ async for chunk in llm.stream(messages=messages):
+ text = chunk.get('content', '')
+ if text:
+ chunks.append(text)
+ if len(''.join(chunks)) >= max_chars:
+ break
+ return ''.join(chunks)
+```
+## π Output Formatting
+
+Use Pydantic models or JSON schemas for structured outputs:
+
+```python
+from pydantic import BaseModel, Field

+
+class MathSolution(BaseModel):
+ solution: str = Field(description="Step-by-step solution")
+ answer: str = Field(description="Final answer")
+ confidence: float = Field(description="Confidence level (0-1)")
+
+agent: Agent = (
+ AgentBuilder()
+ .with_name('Math Solver')
+ .with_llm(OpenAI(model='gpt-4o'))
+ .with_output_schema(MathSolution)
+ .build()
+)
+```
+
+## π Error Handling
+
+Built-in retry mechanisms and error recovery:
+
+```python
+from flo_ai.builder.agent_builder import AgentBuilder
+from flo_ai.llm import OpenAI
+from flo_ai.models.agent import Agent
+
+agent: Agent = (
+ AgentBuilder()
+ .with_name('Robust Agent')
+ .with_llm(OpenAI(model='gpt-4o'))
+ .with_retries(3) # Retry up to 3 times on failure

+### Workflow Visualization
+
+```python
+from typing import Any, List, Callable, Optional
+from flo_ai.arium import AriumBuilder
+from flo_ai.arium.arium import Arium
+from flo_ai.models.agent import Agent
+from flo_ai.tool.base_tool import Tool
+
+# Assume these are defined elsewhere

+)
+
+# Run the workflow
+result: List[Any] = await arium.run(["Customer complaint about billing"])
+```
+
+### Memory and Context Sharing
+
+All agents in an Arium workflow share the same memory, enabling them to build on each other's work:
+
+```python
+from typing import Any, List
+from flo_ai.arium import AriumBuilder
+from flo_ai.arium.memory import MessageMemory
+from flo_ai.arium.arium import Arium
+from flo_ai.models.agent import Agent
+
+# Assume these agents are defined elsewhere
+agent1: Agent = ...
+agent2: Agent = ...
+agent3: Agent = ...
+
+# Custom memory for persistent context
+custom_memory: MessageMemory = MessageMemory()
+
+result: List[Any] = await (
+ AriumBuilder()
+ .with_memory(custom_memory) # Shared across all agents
+ .add_agents([agent1, agent2, agent3])
+ .start_with(agent1)
+ .connect(agent1, agent2)
+ .connect(agent2, agent3)
+ .end_with(agent3)
+ .build_and_run(["Initial context and instructions"])
+)
+
+# Build the arium for reuse
+arium: Arium = (
+ AriumBuilder()
+ .with_memory(custom_memory)
+ .add_agents([agent1, agent2, agent3])
+ .start_with(agent1)
+ .connect(agent1, agent2)
+ .connect(agent2, agent3)
+ .end_with(agent3)
+ .build()
+)
+
+# Memory persists and can be reused
+result2: List[Any] = await arium.run(["Follow-up question based on previous context"])
+```
+
+### π Use Cases for Arium
+
+- **π Content Pipeline**: Research β Writing β Editing β Publishing
+- **π Analysis Workflows**: Data Collection β Processing β Analysis β Reporting

+
+### Builder Pattern Benefits
+
+The AriumBuilder provides a fluent, intuitive API:
+
+```python
+from typing import Any, List
+from flo_ai.arium import AriumBuilder
+from flo_ai.arium.arium import Arium
+from flo_ai.models.agent import Agent
+from flo_ai.tool.base_tool import Tool
+
+# Assume these are defined elsewhere
+agent1: Agent = ...
+agent2: Agent = ...
+tool1: Tool = ...
+inputs: List[str] = ["Your input messages"]
+
+# All builder methods return self for chaining
+workflow: Arium = (
+ AriumBuilder()
+ .add_agent(agent1) # Add components
+ .add_tool(tool1)
+ .start_with(agent1) # Define flow
+ .connect(agent1, tool1)
+ .end_with(tool1)
+ .build() # Create Arium instance
+)
+
+# Or build and run in one step
+result: List[Any] = await (
+ AriumBuilder()
+ .add_agents([agent1, agent2])
+ .start_with(agent1)
+ .connect(agent1, agent2)
+ .end_with(agent2)
+ .build_and_run(inputs) # Build + run together
+)
+```
+
+**Validation Built-in**: The builder automatically validates your workflow:
+- β
Ensures at least one agent/tool
+- β
Requires start and end nodes
+- β
Validates routing functions
+- β
Checks for unreachable nodes
+
+### π YAML-Based Arium Workflows
+
+One of Flo AI's most powerful features is the ability to define entire multi-agent workflows using YAML configuration. This approach makes workflows reproducible, versionable, and easy to modify without changing code.
+
+#### Simple YAML Workflow
+
+```yaml
+metadata:
+ name: "content-analysis-workflow"
+ version: "1.0.0"
+ description: "Multi-agent content analysis and summarization pipeline"
+
+arium:
+ # Define agents inline
+ agents:
+ - name: "analyzer"
+ role: "Content Analyst"
+ job: "Analyze the input content and extract key insights, themes, and important information."
+ model:
+ provider: "openai"
+ name: "gpt-4o-mini"
+ settings:
+ temperature: 0.2
+ max_retries: 3
+ reasoning_pattern: "COT"
+
+ - name: "summarizer"
+ role: "Content Summarizer"
+ job: "Create a concise, actionable summary based on the analysis provided."
+ model:
+ provider: "anthropic"
+ name: "claude-3-5-sonnet-20240620"
+ settings:
+ temperature: 0.1
+ reasoning_pattern: "DIRECT"
+
+ # Define the workflow
+ workflow:
+ start: "analyzer"
+ edges:
+ - from: "analyzer"
+ to: ["summarizer"]
+ end: ["summarizer"]
+```
+
+```python
+import asyncio
+from typing import Any, List
+from flo_ai.arium import AriumBuilder
+
+async def run_yaml_workflow() -> List[Any]:
+ yaml_config = """...""" # Your YAML configuration
+
+ # Create workflow from YAML
+ result: List[Any] = await (
+ AriumBuilder()
+ .from_yaml(yaml_config)
+ .build_and_run(["Analyze this quarterly business report..."])
+ )
+
+ return result
+
+asyncio.run(run_yaml_workflow())
+```
+
+#### Advanced YAML Workflow with Tools and Routing
+
+```yaml
+metadata:

+#### π§ LLM-Powered Routers in YAML (NEW!)
+
+One of the most powerful new features is the ability to define **intelligent LLM routers directly in YAML**. No more writing router functions - just describe your routing logic and let the LLM handle the decisions!
+
+```yaml
+metadata:
+ name: "intelligent-content-workflow"

+ end: ["technical_writer", "creative_writer", "marketing_writer"]
+```
+
+**π― LLM Router Types:**
+
+1. **Smart Router** (`type: smart`): General-purpose routing based on content analysis
+2. **Task Classifier** (`type: task_classifier`): Routes based on keywords and examples
+3. **Conversation Analysis** (`type: conversation_analysis`): Context-aware routing
+4. **Reflection Router** (`type: reflection`): Structured AβBβAβC patterns for reflection workflows
+5. **PlanExecute Router** (`type: plan_execute`): Cursor-style plan-and-execute workflows with step tracking
+
+**β¨ Key Benefits:**
+- π« **No Code Required**: Define routing logic purely in YAML
+- π― **Intelligent Decisions**: LLMs understand context and make smart routing choices
+- π **Easy Configuration**: Simple, declarative syntax
+- π **Version Control**: Track routing changes in YAML files
+- ποΈ **Model Flexibility**: Each router can use different LLM models
+
+```python
+# Using LLM routers is incredibly simple!
+async def run_intelligent_workflow():
+ # No routers dictionary needed - they're defined in YAML!
+ result = await (
+ AriumBuilder()
+ .from_yaml(yaml_str=intelligent_workflow_yaml)
+ .build_and_run(["Write a technical tutorial on Docker containers"])
+ )
+ # The LLM will automatically route to technical_writer! β¨
+ return result
+```
+
+##### π ReflectionRouter: Structured Reflection Workflows (NEW!)
+
+The **ReflectionRouter** is designed specifically for reflection-based workflows that follow AβBβAβC patterns, commonly used for mainβcriticβmainβfinal agent sequences. This pattern is perfect for iterative improvement workflows where a critic agent provides feedback before final processing.
+
+**π Key Features:**
+- π― **Pattern Tracking**: Automatically tracks progress through defined reflection sequences
+- π **Self-Reference Support**: Allows routing back to the same agent (AβBβA patterns)
+- π **Visual Progress**: Shows current position with β pending, β completed indicators
+- π‘οΈ **Loop Prevention**: Built-in safety mechanisms to prevent infinite loops
+- ποΈ **Flexible Patterns**: Supports both 2-agent (AβBβA) and 3-agent (AβBβAβC) flows
+
+**π― Supported Patterns:**
+
+1. **A β B β A** (2 agents): Main β Critic β Main β End
+2. **A β B β A β C** (3 agents): Main β Critic β Main β Final

+```
+
+**π‘ How PlanExecuteRouter Works:**
+
+The router intelligently coordinates workflow phases:
+
+1. **Planning Phase**:
+ - Detects when no execution plan exists
+ - Routes to planner agent to create detailed plan
+ - Plan stored as ExecutionPlan object in PlanAwareMemory
+
+2. **Execution Phase**:
+ - Analyzes plan state and step dependencies
+ - Routes to appropriate agents for next ready steps
+ - Updates step status (pending β in-progress β completed)
+ - Handles parallel execution of independent steps
+
+3. **Review Phase**:
+ - Detects when all steps are completed
+ - Routes to reviewer agent for final validation
+ - Manages error recovery for failed steps
+
+**π Plan Progress Visualization:**
+
+```
+π EXECUTION PLAN: User Authentication API
+π CURRENT PROGRESS:
+β

+#### Using Pre-built Agents in YAML Workflows
+
+```yaml
+metadata:
+ name: "hybrid-workflow"
+ version: "1.0.0"
+ description: "Mix of inline agents and pre-built agent references"
+
+# Import existing agent configurations
+imports:
+ - "agents/content_analyzer.yaml"
+ - "agents/technical_reviewer.yaml"
+
+arium:
+ # Mix of imported and inline agents
+ agents:
+ # Reference imported agent
+ - import: "content_analyzer"
+ name: "analyzer" # Override name if needed
+
+ # Define new agent inline
+ - name: "formatter"
+ role: "Content Formatter"
+ job: "Format the analysis into a professional report structure."
+ model:
+ provider: "openai"
+ name: "gpt-4o-mini"
+
+ # Reference another imported agent
+ - import: "technical_reviewer"
+ name: "reviewer"
+
+ workflow:
+ start: "analyzer"
+ edges:
+ - from: "analyzer"
+ to: ["formatter"]
+ - from: "formatter"
+ to: ["reviewer"]
+ end: ["reviewer"]
+```
+
+#### YAML Workflow Best Practices
+
+1. **Modular Design**: Define reusable agents in YAML, create tools in Python separately
+2. **Clear Naming**: Use descriptive names for agents and workflows
+3. **Variable Usage**: Leverage variables for environment-specific configurations
+4. **Version Control**: Track workflow versions in metadata
+5. **Documentation**: Include descriptions for complex workflows
+6. **Router Functions**: Keep routing logic simple and provide as Python functions
+7. **Tool Management**: Create tools as Python objects and pass them to the builder
+
+#### What Can Be Defined in YAML vs Python
+
+**β
YAML Configuration Supports:**
+- Agent definitions (name, role, job, model settings)
+- Workflow structure (start, edges, end nodes)
+- Agent-to-agent connections
+- Tool and router references (by name)
+- Variables and settings
+- Model configurations
+
+**β YAML Configuration Does NOT Support:**
+- Tool function implementations (must be Python objects)
+- Router function code (must be Python functions)
+- Custom logic execution
+- Direct function definitions
+
+**π‘ Best Practice**: Use YAML for workflow structure and agent configuration, Python for executable logic (tools and routers).
+
+#### Benefits of YAML Workflows
+
+- **π Reproducible**: Version-controlled workflow definitions
+- **π Maintainable**: Easy to modify workflow structure without code changes
+- **π§ͺ Testable**: Different configurations for testing vs. production
+- **π₯ Collaborative**: Non-developers can modify workflow structure
+- **π Deployable**: Easy CI/CD integration with YAML configurations
+- **π Auditable**: Clear workflow definitions for compliance

+# OpenTelemetry Integration for flo_ai
+
+This module provides comprehensive OpenTelemetry integration for the flo_ai framework, enabling you to monitor and track:
+
+- π **LLM Calls**: Track token usage, latency, and errors across different providers
+- π€ **Agent Execution**: Monitor agent performance, tool calls, and retry attempts
+- π **Workflows**: Track workflow execution, node traversals, and bottlenecks
+- π **Metrics**: Export performance metrics to your observability platform
+
+## Quick Start
+
+### 1. Installation
+
+The telemetry dependencies are included in flo_ai. Install with:
+
+```bash
+pip install flo_ai
+```
+
+### 2. Basic Configuration
+
+```python
+from flo_ai import configure_telemetry, shutdown_telemetry
+
+# Configure at the start of your application
+configure_telemetry(
+ service_name="my_ai_app",
+ service_version="1.0.0",
+ console_export=True # For debugging
+)
+
+# ... your application code ...
+
+# Shutdown at the end to flush data
+shutdown_telemetry()
+```
+
+### 3. Export to OTLP Collector
+
+```python
+configure_telemetry(
+ service_name="my_ai_app",
+ otlp_endpoint="http://localhost:4317", # Your OTLP collector
+ console_export=False
+)
+```
+
+## Features
+
+### Automatic Instrumentation
+
+Once configured, telemetry is automatically captured for:
+
+#### LLM Calls
+- Request duration (latency)
+- Token usage (prompt, completion, total)
+- Model and provider information
+- Success/error rates
+- **Streaming support**: Chunk count, stream duration, streaming success rates
+
+#### Agent Execution
+- Total execution time
+- Number of tool calls
+- Retry attempts
+- Conversation history size
+
+#### Workflows (Arium)
+- End-to-end workflow duration
+- Individual node execution times
+- Router decisions
+- Node success/failure rates
+
+### Metrics Collected
+
+#### LLM Metrics
+- `llm.tokens.total` - Total tokens used
+- `llm.tokens.prompt` - Prompt tokens
+- `llm.tokens.completion` - Completion tokens
+- `llm.requests.total` - Number of LLM requests
+- `llm.errors.total` - Number of errors
+- `llm.request.duration` - Request latency histogram
+- `llm.streams.total` - Number of LLM stream requests
+- `llm.stream.chunks.total` - Total number of stream chunks received
+- `llm.stream.duration` - Stream request latency histogram
+
+#### Agent Metrics
+- `agent.executions.total` - Number of agent executions
+- `agent.tool_calls.total` - Number of tool calls
+- `agent.retries.total` - Number of retries
+- `agent.errors.total` - Number of errors
+- `agent.execution.duration` - Execution time histogram
+
+#### Workflow Metrics
+- `workflow.executions.total` - Number of workflow executions
+- `workflow.nodes.executed` - Number of nodes executed
+- `workflow.errors.total` - Number of errors
+- `workflow.execution.duration` - Workflow execution time
+- `workflow.node.duration` - Node execution time
+
+### Spans (Traces)
+
+Spans are automatically created for:
+- `llm.{provider}.generate` - LLM API calls
+- `agent.{name}.run` - Agent executions
+- `agent.tool.{name}` - Tool executions
+- `workflow.{name}` - Workflow executions
+- `workflow.node.{name}` - Node executions
+
+## Configuration Options
+
+### Environment Variables
+
+- `FLO_ENV` - Environment name (default: "development")
+- `FLO_OTLP_ENDPOINT` - OTLP endpoint URL
+
+### Configuration Parameters
+
+```python
+configure_telemetry(
+ service_name: str = "flo_ai", # Service name for telemetry
+ service_version: str = "1.0.0", # Service version
+ environment: str = None, # Environment (dev/staging/prod)
+ otlp_endpoint: str = None, # OTLP collector endpoint
+ console_export: bool = False, # Export to console
+ additional_attributes: Dict[str, Any] = None # Custom resource attributes
+)
+```
+

+ otlp_endpoint="http://localhost:4317", # Cloud Ops collector
+ additional_attributes={
+ "gcp.project_id": "your-project-id"
+ }
+)
+```
+
+#### Azure Monitor
+```python
+# Use Azure Monitor OTLP endpoint
+configure_telemetry(
+ service_name="my_app",
+ otlp_endpoint="https://.monitor.azure.com/opentelemetry/v1/traces"
+)
+```
+
+## Advanced Usage
+
+### Custom Spans
+
+```python
+from flo_ai import get_tracer
+
+tracer = get_tracer()
+if tracer:
+ with tracer.start_as_current_span("custom_operation") as span:
+ span.set_attribute("custom.attribute", "value")
+ # Your code here
+```
+
+### Custom Metrics
+
+```python
+from flo_ai import get_meter
+
+meter = get_meter()
+if meter:
+ # Create a counter
+ my_counter = meter.create_counter(
+ name="my_custom_counter",
+ description="Custom operation counter",
+ unit="operations"
+ )
+ my_counter.add(1, {"operation": "custom"})
+
+ # Create a histogram
+ my_histogram = meter.create_histogram(
+ name="my_custom_duration",
+ description="Custom operation duration",
+ unit="ms"
+ )
+ my_histogram.record(123.45, {"operation": "custom"})
+```
+
+### Filtering Telemetry
+
+To disable telemetry temporarily:
+
+```python
+# Don't call configure_telemetry()
+# The framework will detect no telemetry is configured and skip instrumentation
+```
+
+## Best Practices
+
+### 1. Configure Once at Startup
+
+```python
+def initialize_app():
+ configure_telemetry(
+ service_name="my_app",
+ otlp_endpoint=os.getenv("OTLP_ENDPOINT"),
+ environment=os.getenv("ENV", "development")
+ )
+```
+
+### 2. Always Shutdown on Exit
+
+```python
+import atexit
+from flo_ai import shutdown_telemetry
+
+atexit.register(shutdown_telemetry)
+```
+
+### 3. Use Meaningful Service Names
+
+```python
+configure_telemetry(
+ service_name="customer-support-bot", # Specific and descriptive
+ service_version="2.1.0"
+)
+```
+
+### 4. Add Context with Attributes
+
+```python
+configure_telemetry(
+ service_name="my_app",
+ additional_attributes={
+ "deployment.region": "us-west-2",
+ "team": "ml-platform",
+ "environment.type": "production"
+ }
+)
+```
+
+### 5. Monitor Key Metrics
+
+Focus on:
+- Token usage trends (cost monitoring)
+- LLM latency (performance)
+- Error rates (reliability)
+- Agent execution times (user experience)
+
+## Performance Impact
+
+The telemetry instrumentation has minimal performance overhead:
+
+- **LLM calls**: < 1ms additional latency
+- **Agent execution**: < 2ms overhead
+- **Workflow execution**: < 5ms overhead
+- **Memory**: ~10MB for buffering spans/metrics
+
+Metrics are exported asynchronously and don't block your application.
+
+## Troubleshooting
+
+### No Data Appearing
+
+1. Check OTLP endpoint is accessible:
+ ```bash
+ curl http://localhost:4317
+ ```
+
+2. Enable console export for debugging:
+ ```python
+ configure_telemetry(console_export=True)
+ ```
+
+3. Ensure shutdown is called:
+ ```python
+ shutdown_telemetry()
+ ```
+
+### High Memory Usage
+
+If you see high memory usage:
+
+1. Reduce export interval (default is 5 seconds)
+2. Ensure shutdown is called to flush buffers
+3. Check your OTLP collector is accepting data
+
+### Missing Token Metrics
+
+Token metrics are only available for providers that return usage data:
+- β
OpenAI (full support)
+- β
Anthropic (full support)
+- β
Gemini (full support)
+- β οΈ Ollama (limited support)
+
+## Examples
+
+See the [telemetry_example.py](../../examples/telemetry_example.py) file for complete examples including:
+
+- Basic agent with LLM telemetry
+- Agent with tool calls
+- Workflow telemetry with Arium
+- Multiple LLM providers
+- Error tracking

+## Contributing
+
+To add telemetry to new components:
+
+1. Import instrumentation utilities:
+ ```python
+ from flo_ai.telemetry.instrumentation import trace_llm_call, agent_metrics
+ from flo_ai.telemetry import get_tracer
+ ```
+
+2. Add decorators or manual instrumentation
+3. Record metrics using the appropriate metrics instance
+4. Add span attributes for context
