## Installation

### 1. Install iFlow CLI

If you haven't installed iFlow CLI yet:

**Mac/Linux/Ubuntu:**
```bash
bash -c "$(curl -fsSL https://gitee.com/iflow-ai/iflow-cli/raw/main/install.sh)"
```

**Windows:**
```bash
npm install -g @iflow-ai/iflow-cli@latest
```

### 2. Install the SDK

**Install from PyPI (Recommended):**

```bash
pip install iflow-cli-sdk
```

**Or install from source:**

```bash
git clone https://github.com/yourusername/iflow-cli-sdk-python.git
cd iflow-cli-sdk-python
pip install -e .
```

## Quick Start

The SDK **automatically manages the iFlow process** - no manual setup required!

### Default Usage (Automatic Process Management)

```python
import asyncio
from iflow_sdk import IFlowClient

async def main():
    # SDK automatically:
    # 1. Detects if iFlow is installed
    # 2. Starts iFlow process if not running
    # 3. Finds an available port
    # 4. Cleans up on exit
    async with IFlowClient() as client:
        await client.send_message("Hello, iFlow!")
        
        async for message in client.receive_messages():
            print(message)
            # Process messages...

asyncio.run(main())
```

**No need to manually start iFlow!** The SDK handles everything for you.

### Advanced: Manual Process Control

If you need to manage iFlow yourself (rare cases):

```python
import asyncio
from iflow_sdk import IFlowClient, IFlowOptions

async def main():
    # Disable automatic process management
    options = IFlowOptions(
        auto_start_process=False,
        url="ws://localhost:8090/acp"  # Connect to existing iFlow
    )
    
    async with IFlowClient(options) as client:
        await client.send_message("Hello, iFlow!")

asyncio.run(main())
```

**Note:** Manual mode requires you to start iFlow separately:
```bash
iflow --experimental-acp --port 8090
```

### Simple Examples

#### Simple Query

```python
import asyncio
from iflow_sdk import query

async def main():
    response = await query("What is the capital of France?")
    print(response)  # "The capital of France is Paris."

asyncio.run(main())
```

#### Interactive Conversation

```python
import asyncio
from iflow_sdk import IFlowClient, AssistantMessage, TaskFinishMessage

async def chat():
    async with IFlowClient() as client:
        await client.send_message("Explain quantum computing")
        
        async for message in client.receive_messages():
            if isinstance(message, AssistantMessage):
                print(message.chunk.text, end="", flush=True)
            elif isinstance(message, TaskFinishMessage):
                break

asyncio.run(chat())
```

#### Tool Call Control with Agent Information

```python
import asyncio
from iflow_sdk import IFlowClient, IFlowOptions, ApprovalMode, ToolCallMessage, TaskFinishMessage, AgentInfo

async def main():
    options = IFlowOptions(approval_mode=ApprovalMode.YOLO)  # Default: auto-execute with fallback
    
    async with IFlowClient(options) as client:
        await client.send_message("Create a file called test.txt")
        
        async for message in client.receive_messages():
            if isinstance(message, ToolCallMessage):
                print(f"Tool requested: {message.tool_name}")
                print(f"Tool status: {message.status}")
                
                # Access agent information
                if message.agent_info:
                    print(f"Agent ID: {message.agent_info.agent_id}")
                    print(f"Task ID: {message.agent_info.task_id}")
                    print(f"Agent Index: {message.agent_info.agent_index}")
                
                # Access tool execution details (added dynamically)
                if hasattr(message, 'args'):
                    print(f"Tool arguments: {message.args}")
                if hasattr(message, 'output'):
                    print(f"Tool output: {message.output}")
                    
            elif isinstance(message, TaskFinishMessage):
                break

asyncio.run(main())
```

#### Working with AgentInfo

```python
import asyncio
from iflow_sdk import AgentInfo, IFlowClient, AssistantMessage, CreateAgentConfig, IFlowOptions, ToolCallMessage


async def agent_info_example():
    # 创建Agent配置
    agents = [
        CreateAgentConfig(
            agentType="code-reviewer",
            name="reviewer",
            description="Code review specialist",
            whenToUse="For code review and quality checks",
            allowedTools=["fs", "grep"],
            allowedMcps=["eslint", "prettier"],
            systemPrompt="You are a code review expert.",
            proactive=False,
            location="project"
        ),
        CreateAgentConfig(
            agentType="test-writer",

            systemPrompt="You are a test writing expert.",
            location="project"
        )
    ]


    options = IFlowOptions(agents=agents)

    # Use in conversation
    async with IFlowClient(options) as client:
        await client.send_message("$test-writer Write a unit test")

        async for message in client.receive_messages():
            if isinstance(message, ToolCallMessage):
                print(f"tool_name: {message.tool_name}")
                
                if hasattr(message, 'output') and message.output:
                    print(f"output: {message.output}")
                
                if hasattr(message, 'args') and message.args:
                    print(f"args: {message.args}")
                    
            elif isinstance(message, AssistantMessage):
                print(message.chunk.text, end="", flush=True)


asyncio.run(agent_info_example())
