## Key Features

### 1. Automatic Tool Registration

Users can create tools with a simple decorator:

```python
from indusagi import registry

@registry.register
def my_tool(param: str) -> str:
    """What your tool does."""
    return f"Result: {param}"
```

Then just import and the agent can use it:
```python
import custom_tools
agent.process_with_tools("Use my_tool", tools=registry.schemas, tool_executor=registry)
```

### 2. Auto-Generated OpenAI Schemas

The framework automatically generates OpenAI-compatible schemas from:
- Function signatures
- Type hints
- Docstrings
- Parameter descriptions

No manual schema writing needed!

### 3. Multi-Agent Orchestration

Three specialized agents with intelligent routing:
- **General Agent:** General-purpose queries
- **Math Expert:** Mathematical calculations
- **Time Keeper:** Date and time queries

The orchestrator automatically routes queries to the best agent.

### 4. Conversation Memory

Persistent conversation storage:
```python
memory = ConversationMemory(max_messages=1000)
memory.save_to_file("conversation.json")
memory.load_from_file("conversation.json")
```

### 5. Beautiful CLI

Professional command-line interface:
```bash
indusagi run "What is 25 * 48?"
indusagi interactive
indusagi list-tools
```

## Usage Examples

### Example 1: Simple Query

```python
from indusagi import Agent

agent = Agent("Helper", "Helpful assistant")
response = agent.process_with_tools(
    "What is 144 divided by 12?",
    tools=registry.schemas,
    tool_executor=registry
)
# Agent uses calculator tool and responds: "144 divided by 12 is 12"
```

### Example 2: Multiple Tools

```python
response = agent.process_with_tools(
    "What's the weather in Tokyo and what time is it now?",
    tools=registry.schemas,
    tool_executor=registry
)
# Agent uses get_weather and get_time tools
```

### Example 3: Custom Tools

```python
import custom_tools  # Registers 9 custom tools

response = agent.process_with_tools(
    "Generate a random number between 1 and 100 and get today's date",
    tools=registry.schemas,
    tool_executor=registry
)
# Agent uses random_number and get_date tools
```

### Example 4: Orchestrator

```python
from indusagi import create_orchestrator

orchestrator = create_orchestrator()
response = orchestrator.process("Calculate 25 * 48 and get the current time")
# Automatically routes to Math Expert for calculation, Time Keeper for time
```

### Example 5: CLI

```bash
# Single query
indusagi run "What is the date 30 days from now?"

# Interactive mode
indusagi interactive

# List all tools
indusagi list-tools
```

```python
@registry.register(dangerous=True)
def risky_tool(param: str) -> str:
    """Potentially dangerous operation."""
    pass
```

File tools only allow:
- .txt files
- Current directory only
- No directory traversal

### 4. Error Handling

All tools return error messages as strings instead of raising exceptions.

## Installation

### Method 1: Editable Install (Development)

```bash
cd "C:\Users\Varun israni\agent-framework-build-plan"
python -m pip install -e .
```

### Method 2: Direct Install

```bash
pip install .
```

### Setup

1. Copy `.env.example` to `.env`
2. Add your OpenAI API key to `.env`
3. Run tests to verify: `python test_integration_quick.py`

---

## Known Issues and Limitations

### 1. Tool Usage is Not Forced

OpenAI decides whether to use tools. Sometimes it will:
- Calculate simple math without the calculator
- Provide general answers instead of using tools
- Use its training data instead of real-time tools

**This is expected behavior** and not a bug.

### 2. Windows Console Encoding

Unicode emoji characters cause issues on Windows. Solution: Use ASCII characters.

### 3. API Costs

Each tool call makes API requests, which incur costs. Monitor usage.

### 4. Rate Limiting

OpenAI has rate limits. Implement exponential backoff if needed.

---

## Lessons Learned

### 1. Parallel Development Works

Using multiple sub-agents to build different components simultaneously was highly effective.

### 2. Integration is Critical

Having working files in the root directory required careful integration into the package structure.

### 3. Documentation is Essential

Comprehensive docs (2,500+ lines) ensure users can actually use the framework.

### 4. Testing Proves Everything

Extensive testing (255+ tests) catches integration issues early.

### 5. OpenAI vs Anthropic Differences

Documentation was for Anthropic but we used OpenAI. Adaptation was necessary.
