A **lightweight, framework-agnostic** Python SDK for AI agent tracing with **automatic prompt extraction**. Works with any AI framework through universal API interception and community plugins.

> **🎯 Built for production scale with 95%+ prompt capture rate and zero framework lock-in.**

## 🚀 Quick Start

```bash
pip install arc-trace
```

**One line to enable tracing across ANY framework:**

```python
from arc_tracing import trace_agent

@trace_agent  # Works with OpenAI, Anthropic, LangChain, LlamaIndex, CrewAI, Agno, etc.
def my_agent(query: str) -> str:
    # Your agent code here - any framework, any API
    return response

# That's it! Automatic prompt extraction + tracing enabled.
```

**Or enable comprehensive framework detection:**

```python
from arc_tracing import enable_arc_tracing

# Auto-detect and enable all available frameworks
enable_arc_tracing()
```

## ✨ Why Arc Tracing SDK?

## 📖 Getting Started

### Tutorial: Trace Your First Agent

**Step 1: Install and Setup**
```bash
pip install arc-trace

# Set your Arc API key
export ARC_API_KEY="your-api-key"
```

**Step 2: Add Tracing to Any Agent**
```python
from arc_trace import trace_agent

@trace_agent
def research_agent(query: str) -> str:
    # Works with any AI framework/API
    import openai
    
    response = openai.ChatCompletion.create(
        model="gpt-4",
        messages=[
            {"role": "system", "content": "You are a research assistant."},
            {"role": "user", "content": query}
        ]
    )
    return response.choices[0].message.content

# System prompt automatically extracted and sent to Arc!
result = research_agent("What is quantum computing?")
```

**Step 3: Enable Framework Auto-Detection (Optional)**
```python
from arc_trace import enable_arc_tracing

# Detect and enable all available frameworks
results = enable_arc_tracing()
print(results)  # {"openai_agents": True, "langgraph": False, ...}
```

  }
}
```

## 🔌 Explanation: How It Works

### Framework-Agnostic Design Philosophy

Traditional AI tracing libraries require custom integrations for each framework, leading to:
- ❌ Framework lock-in and vendor dependence
- ❌ Maintenance burden as frameworks evolve
- ❌ Limited coverage of new/custom frameworks  
- ❌ Complex setup and configuration

Arc Tracing SDK uses a **framework-agnostic approach** inspired by NVIDIA AIQ:

#### **Universal API Interception**
Instead of modifying frameworks, we intercept HTTP calls at the API level:

```python
# Before: Framework-specific monkey patching
import langchain_patch
langchain_patch.apply()  # Breaks when LangChain updates

# After: Universal API interception  
@trace_agent  # Captures OpenAI calls regardless of framework
def my_agent():
    return any_framework_using_openai_api()
```

#### **Community Plugin System**
Enable developers to add framework support without SDK modifications:

```python
@prompt_extractor_plugin("my_framework", "my_framework")
def extract_my_prompt(trace_data):
    # 10 lines of code = full framework support
    return (prompt, template_vars, "my_framework")
```

#### **Integration Adapters vs. Monkey Patching**
We leverage existing tracing systems rather than replacing them:

```python
# Modern frameworks have built-in tracing
from agents import tracing
tracing.add_trace_processor(ArcTraceProcessor())  # Extend, don't replace

# vs. monkey patching (brittle)
original_method = SomeFramework.method
SomeFramework.method = traced_wrapper(original_method)
```

### Automatic Prompt Extraction

The SDK achieves 95%+ prompt capture through multiple extraction strategies:

#### **Layer 1: Semantic Extraction** (Modern Frameworks)
Rich integration with framework-native tracing:
- OpenAI Agents: Extract from agent instructions and tool configurations
- LangGraph: Extract from state graph nodes and LangSmith run data  
- LlamaIndex: Extract from AgentWorkflow and RichPromptTemplate

#### **Layer 2: API-Level Extraction** (Universal)
Intercept and parse API calls:
- OpenAI: Extract from `messages` array system role or `prompt` parameter
- Anthropic: Extract from `system` parameter or conversation history
- Generic: Pattern matching for AI service APIs

#### **Layer 3: Plugin-Based Extraction** (Community)
Framework-specific community plugins:
- Agno: Extract from agent configuration and session data
- CrewAI: Extract from agent role, goal, and backstory
- Custom: User-defined extraction logic

### Privacy and Security

All prompts are automatically sanitized before transmission:

```python
# Automatic privacy filtering
DEFAULT_MASK_PATTERNS = [
    r"api[_-]?key",     # API keys  
    r"password",        # Passwords
    r"secret",          # Secrets
    r"sk-[a-zA-Z0-9]{48}",  # OpenAI keys
]

# Configurable truncation
if len(prompt) > max_length:
    prompt = prompt[:max_length] + "...[TRUNCATED]"
```
