## Philosophy: Developer Authority First

Arshai empowers you to build exactly what you need, when you need it, how you need it. **You control every component, dependency, and interaction.** No magic, no hidden behavior, no framework lock-in.

### The Arshai Way vs Traditional Frameworks

**❌ Traditional Framework Approach:**
```python
# Framework controls everything - what's happening inside?
framework = AIFramework()
framework.load_config("config.yaml") 
agent = framework.create_agent("chatbot")  # Hidden creation
response = agent.chat("Hello")  # Opaque behavior
```

**✅ Arshai Approach - You're In Control:**
```python
# You create, configure, and control everything
llm_config = ILLMConfig(model="gpt-4", temperature=0.7)
llm_client = OpenAIClient(llm_config)  # You create it

agent = ChatAgent(
    llm_client=llm_client,  # You inject dependencies  
    system_prompt="Be helpful",  # You configure behavior
    memory=memory_manager  # You manage state
)

response = await agent.process(input_data)  # You control the flow
```

## Three-Layer Architecture

### Layer 1: LLM Clients (Foundation)
**Minimal Developer Authority** - Standardized access to AI providers

```python
from arshai.llms.openai import OpenAIClient
from arshai.core.interfaces.illm import ILLMConfig, ILLMInput

# Direct instantiation - you create when needed
config = ILLMConfig(model="gpt-4", temperature=0.7)
llm = OpenAIClient(config)

# Unified interface across all providers
llm_input = ILLMInput(
    system_prompt="You are a helpful assistant",
    user_message="What's the weather like?",
    regular_functions={"get_weather": get_weather_func},
    background_tasks={"log_interaction": log_func}  # Fire-and-forget
)

response = await llm.chat(llm_input)
```

**Supported Providers:**
- **OpenAI** - Direct API with streaming and function calling
- **Azure OpenAI** - Enterprise deployment with native parsing
- **Google Gemini** - Native SDK with dual authentication  
- **OpenRouter** - Access to Claude, Llama, and 200+ models
- **Extensible** - Add new providers by implementing `ILLM` interface

### Layer 2: Agents (Business Logic)

```python
from arshai.agents.base import BaseAgent
from arshai.core.interfaces.iagent import IAgentInput

class CustomerServiceAgent(BaseAgent):
    """Your custom agent with your business logic."""
    
    def __init__(self, llm_client: ILLM, knowledge_base: KnowledgeBase):
        super().__init__(llm_client, "You are a customer service expert")
        self.knowledge_base = knowledge_base
    
    async def process(self, input: IAgentInput) -> Dict[str, Any]:
        # Your custom preprocessing
        context = await self._analyze_request(input.message)
        
        # Define tools for this specific agent
        async def search_kb(query: str) -> str:
            return await self.knowledge_base.search(query)
        
        async def log_issue(issue: str) -> None:
            """BACKGROUND TASK: Log customer issue."""
            await self.issue_tracker.create_ticket(issue)
        
        # Your LLM integration with custom tools
        llm_input = ILLMInput(
            system_prompt=self.system_prompt,
            user_message=f"Context: {context}\nUser: {input.message}",
            regular_functions={"search_knowledge": search_kb},
            background_tasks={"log_issue": log_issue}
        )
        
        result = await self.llm_client.chat(llm_input)
        
        # Your custom post-processing
        return {
            "response": result["llm_response"],
            "confidence": self._calculate_confidence(result),

        self.memory = memory
        
    async def handle_request(self, user_message: str, user_id: str) -> Dict[str, Any]:

        # Step 1: Retrieve user history
        history = await self.memory.retrieve({"user_id": user_id})
        
        # Step 2: Triage the request

            message=user_message,
            metadata={"history": history, "user_id": user_id}
        )
        triage_result = await self.triage_agent.process(triage_input)
        
        # Step 3: Route based on triage (your business logic)
        if triage_result["urgency"] == "high":

            message=user_message,
            metadata={
                "user_id": user_id,
                "triage": triage_result,
                "history": history
            }
        )
        final_result = await agent.process(support_input)
        
        # Step 5: Update memory (your state management)
        await self.memory.store({
            "user_id": user_id,
            "interaction": {

## Quick Start Guide 🚀

### 1. Quick Start - Your First Agent

```python
from arshai.llms.openai import OpenAIClient
from arshai.agents.base import BaseAgent
from arshai.core.interfaces.illm import ILLMConfig
from arshai.core.interfaces.iagent import IAgentInput

# Step 1: Create your LLM client (you control this)
llm_config = ILLMConfig(
    model="gpt-4o",           # Latest model
    temperature=0.7,         # Creativity level
    max_tokens=2000          # Response length
)
llm_client = OpenAIClient(llm_config)

# Step 2: Create your agent (you define the behavior)
agent = BaseAgent(
    llm_client=llm_client, 
    system_prompt="You are an expert Python programming assistant. Provide clear, practical examples with explanations."
)

# Step 3: Use your agent (you control the interaction)
response = await agent.process(IAgentInput(
    message="How do I handle async/await in Python? Show me a practical example."
))

print(response)
# Output: Detailed explanation with code examples
```

### 1b. Agent with Memory (Conversation Context)

```python
from arshai.agents.working_memory import WorkingMemoryAgent
from arshai.memory.working_memory.in_memory_manager import InMemoryManager

# Create memory system for conversation context
memory = InMemoryManager(ttl=1800)  # 30-minute memory

# Create agent with memory capabilities
conversation_agent = WorkingMemoryAgent(
    llm_client=llm_client,
    memory_manager=memory,
    system_prompt="You are a helpful assistant that remembers our conversation context."
)

# First interaction
response1 = await conversation_agent.process(IAgentInput(
    message="My name is Alex and I'm learning Python.",
    metadata={"conversation_id": "conv_123"}
))

# Second interaction - agent remembers context
response2 = await conversation_agent.process(IAgentInput(
    message="What was my name again?",
    metadata={"conversation_id": "conv_123"}
))

print(response2)  # Will remember "Alex"
```

### 1c. Multi-Provider Setup

```python
# Use different providers for different tasks
from arshai.llms.openai import OpenAIClient
from arshai.llms.google_genai import GeminiClient
from arshai.llms.openrouter import OpenRouterClient

# Fast model for simple tasks
fast_llm = OpenAIClient(ILLMConfig(model="gpt-4o-mini", temperature=0.3))

# Powerful model for complex analysis
strong_llm = OpenAIClient(ILLMConfig(model="gpt-4o", temperature=0.5))

# Alternative provider for variety
gemini_llm = GeminiClient(ILLMConfig(model="gemini-1.5-pro", temperature=0.7))

# Access to specialized models
openrouter_llm = OpenRouterClient(ILLMConfig(
    model="anthropic/claude-3.5-sonnet",  # Claude via OpenRouter
    temperature=0.6
))

# Create specialized agents
quick_agent = BaseAgent(fast_llm, "Quick responses for simple questions")
analysis_agent = BaseAgent(strong_llm, "Deep analysis and complex reasoning")
creative_agent = BaseAgent(gemini_llm, "Creative writing and brainstorming")
research_agent = BaseAgent(openrouter_llm, "Research and detailed explanations")

# Use the right agent for each task
quick_response = await quick_agent.process(IAgentInput(
    message="What's 15% tip on $42?"
))

analysis_response = await analysis_agent.process(IAgentInput(
    message="Analyze the pros and cons of microservices vs monolithic architecture for a startup"
))
```

```python
# Configure performance settings via environment variables
import os

# HTTP connection pooling
os.environ['ARSHAI_MAX_CONNECTIONS'] = '100'
os.environ['ARSHAI_MAX_CONNECTIONS_PER_HOST'] = '10'

# Thread pool management  
os.environ['ARSHAI_MAX_THREADS'] = '32'

# Memory management
os.environ['ARSHAI_MAX_MEMORY_MB'] = '2048'
os.environ['ARSHAI_CLEANUP_INTERVAL'] = '300'

```dockerfile
FROM python:3.11-slim

WORKDIR /app
COPY requirements.txt .
RUN pip install -r requirements.txt

# Performance configuration
ENV ARSHAI_MAX_CONNECTIONS=100
ENV ARSHAI_MAX_CONNECTIONS_PER_HOST=20
ENV ARSHAI_MAX_THREADS=32

COPY . .
CMD ["python", "main.py"]
```

### Observability

```python
from arshai.observability import ObservabilityConfig

# Configure monitoring (optional - your choice)
obs_config = ObservabilityConfig.from_yaml("monitoring.yaml")
client = LLMFactory.create_with_observability(
    provider="openai",
    config=llm_config,
    observability_config=obs_config
)

# Automatic metrics collection:
# ✅ llm_time_to_first_token_seconds
# ✅ llm_time_to_last_token_seconds  
# ✅ llm_completion_tokens
# ✅ llm_requests_total
```

## Key Interfaces

### LLM Provider Interface

```python
from arshai.core.interfaces.illm import ILLM, ILLMConfig, ILLMInput

# All LLM providers implement this interface
class CustomLLMProvider(ILLM):
    def __init__(self, config: ILLMConfig):
        self.config = config
    
    async def chat(self, input: ILLMInput) -> Dict[str, Any]:
        # Your implementation
        pass
    
    async def stream(self, input: ILLMInput) -> AsyncGenerator:
        # Your streaming implementation  
        pass
```

### Agent Interface

```python
from arshai.core.interfaces.iagent import IAgent, IAgentInput

class MyCustomAgent(IAgent):
    def __init__(self, llm_client: ILLM, **kwargs):
        self.llm_client = llm_client
        # You control initialization
    
    async def process(self, input: IAgentInput) -> Any:
        # You control the processing logic
        # Return anything - string, dict, object, generator
        pass
```

## Testing

```python
import pytest
from unittest.mock import AsyncMock

async def test_my_agent():
    # Easy testing with dependency injection
    mock_llm = AsyncMock()
    mock_llm.chat.return_value = {
        "llm_response": "Test response",
        "usage": {"total_tokens": 50}
    }
    
    # Your agent with mocked dependencies
    agent = MyAgent(mock_llm, "Test prompt")
    
    result = await agent.process(IAgentInput(message="Test"))
    
    assert result == expected_result
    mock_llm.chat.assert_called_once()
```

## Extension and Customization

### Add New LLM Provider

```python
class MyLLMProvider(ILLM):
    """Your custom LLM provider."""
    
    def __init__(self, config: ILLMConfig):
        self.config = config
        # Your initialization
    
    async def chat(self, input: ILLMInput) -> Dict[str, Any]:
        # Your provider implementation
        return {
            "llm_response": "Your response",
            "usage": {"total_tokens": 100}
        }
```

### Create Custom Agent Types

```python
class DomainSpecificAgent(BaseAgent):
    """Agent specialized for your domain."""
    
    def __init__(self, llm_client: ILLM, domain_tools: List[Callable]):
        super().__init__(llm_client, "Domain-specific system prompt")
        self.domain_tools = {tool.__name__: tool for tool in domain_tools}
    
    async def process(self, input: IAgentInput) -> Dict[str, Any]:
        # Your domain-specific processing
        llm_input = ILLMInput(
            system_prompt=self.system_prompt,
            user_message=input.message,
            regular_functions=self.domain_tools
        )
        
        result = await self.llm_client.chat(llm_input)
        return self._format_domain_response(result)
## Observability and Monitoring

Arshai provides enterprise-grade observability for production AI systems with comprehensive OpenTelemetry integration and zero-fallback monitoring.

### 🎯 Key Features

- **Zero-Fallback Monitoring**: Always capture the 4 critical LLM metrics without any fallback mechanisms
- **OpenTelemetry Native**: Export to any OTLP-compatible backend (Jaeger, Prometheus, Datadog, New Relic)
- **Phoenix AI Observability**: Advanced LLM interaction monitoring with comprehensive input/output tracing
- **Automatic Factory Integration**: Zero-code observability through intelligent factory wrapping
- **Real-time Input/Output Capture**: Automatic capture of prompts, responses, and usage metrics
- **LLM Usage Data Integration**: Accurate token counting from LLM response usage data
- **Streaming Observability**: Real-time token-level timing for streaming responses
- **Non-Intrusive Design**: Zero side effects on LLM calls with graceful degradation
- **Production-Ready**: Comprehensive configuration, privacy controls, and performance optimization

### 📊 The Four Key Metrics

Every LLM interaction automatically captures these critical performance metrics:

| Metric | Description | Use Case |
|--------|-------------|----------|
| `llm_time_to_first_token_seconds` | Latency from request start to first token | User experience, response time SLAs |
| `llm_time_to_last_token_seconds` | Total response generation time | End-to-end performance monitoring |
| `llm_duration_first_to_last_token_seconds` | Token generation duration | Throughput analysis, model performance |
| `llm_completion_tokens` | Accurate completion token count | Cost tracking, usage monitoring |

```

### 🚀 Quick Setup

#### 1. Basic Configuration

```yaml
# config.yaml
observability:
  service_name: "my-ai-service"
  track_token_timing: true
  otlp_endpoint: "http://localhost:4317"
  
  # Phoenix AI Observability
  phoenix_enabled: true
  phoenix_endpoint: "http://localhost:6006"
  
  # Privacy and data capture
  log_prompts: true
  log_responses: true
```

#### 2. Automatic Factory Integration

```python
from arshai.config.settings import Settings
from arshai.core.interfaces.illm import ILLMInput

# Settings automatically detects observability configuration
settings = Settings()

# Create LLM - observability is automatically enabled if configured
llm = settings.create_llm()  

# All calls are automatically instrumented with zero configuration
input_data = ILLMInput(
    system_prompt="You are a helpful assistant.",
    user_message="Hello!"
)

response = llm.chat_completion(input_data)

# Automatic capture includes:
# ✅ Input messages (system prompt + user message)
# ✅ Output response (full LLM response)
# ✅ Usage metrics (prompt/completion/total tokens)
# ✅ Timing data (first token, last token, total duration)
# ✅ Invocation parameters (model, temperature, provider)
# ✅ Span naming (llm.chat_completion not llm.<lambda>)
```
