### 🤖 Cursor Assistant

I'll add support for the Kimi K2 model in the context experiment. Based on the Moonshot API documentation, the Kimi API is OpenAI-compatible, using `https://api.moonshot.cn/v1` as the base URL.

---

### 🤖 Cursor Assistant

Perfect! I've successfully added support for the Kimi K2 model (`kimi-k2-0905-preview`) to the context experiment. Here's what I've implemented:

## Changes Made:

### 1. **Configuration Updates (`config.py`)**
- Added Moonshot API configuration with base URL `https://api.moonshot.cn/v1`
- Added support for `kimi` and `moonshot` as provider options
- Set default model to `kimi-k2-0905-preview` for Kimi provider

### 2. **Agent Updates (`agent.py`)**
- Added Kimi/Moonshot provider support in the `ContextAwareAgent` class
- Configured OpenAI client to work with Moonshot's API endpoint
- Updated docstrings to reflect the new provider option

### 3. **Main Script Updates (`main.py`)**
- Added `kimi` and `moonshot` to the provider choices in argument parser
- Added API key handling for `MOONSHOT_API_KEY` environment variable
- Updated help text to mention the new provider

### 4. **Environment Configuration (`env.example`)**
- Added `MOONSHOT_API_KEY` to the example environment file
- Updated comments to reflect all three supported providers

### 5. **Testing Scripts**
- Created comprehensive test script (`test_kimi.py`) with multiple test scenarios
- Created quick verification script (`quick_test_kimi.py`) for rapid testing

### 6. **Documentation (`README.md`)**
- Updated provider list to include Kimi/Moonshot
- Added Kimi model specifications and features
- Included testing instructions for Kimi integration
- Added API key source information for Moonshot platform

## How to Use:

1. **Get API Key**: Visit [Moonshot Platform](https://platform.moonshot.cn/) to obtain your API key

2. **Set Environment Variable**:
```bash
export MOONSHOT_API_KEY=your_api_key_here
# Or add to .env file
```

3. **Run Tests**:
```bash
# Quick test
python quick_test_kimi.py

# Comprehensive test suite
python test_kimi.py

# Use in main script
python main.py --provider kimi --mode interactive
```

4. **Use in Code**:
```python
from agent import ContextAwareAgent, ContextMode

agent = ContextAwareAgent(
    api_key="your_api_key",
    provider="kimi",  # or "moonshot"
    context_mode=ContextMode.FULL
)

response = agent.process("Your query here")
```

The integration is fully compatible with all existing features including tool calls (PDF parsing, currency conversion, calculator, code interpreter) and ablation studies. The Kimi K2 model is particularly well-suited for advanced reasoning tasks and supports both English and Chinese conversations.

In the main script, the available commands does not allow to switch provider. Should allow listing providers and selecting provider

Provider: DOUBAO | Model: default
============================================================
Available commands:
  - Type your task/question
  - 'samples' to see sample tasks
  - 'sample <number>' to run a sample task
  - 'create_pdfs' to create sample PDF files
  - 'modes' to see available context modes
  - 'mode <mode_name>' to switch context mode
  - 'reset' to reset agent trajectory
  - 'quit' to exit

---

### 🤖 Cursor Assistant

You're absolutely right! The interactive mode should allow users to switch providers dynamically. Let me add commands to list and switch providers.

---

### 🤖 Cursor Assistant

## ✅ Provider Switching Successfully Implemented!

I've added comprehensive provider switching functionality to the interactive mode. Here's what's been implemented:

### New Interactive Commands:

1. **`providers`** - Lists all available LLM providers (SiliconFlow, Doubao, Kimi/Moonshot) with current status
2. **`provider <name>`** - Switches to a different provider dynamically (e.g., `provider kimi`)
3. **`status`** - Shows current configuration including provider, model, context mode, and API key status
4. **`help`** - Displays all available commands with descriptions

### Key Features:

- **Dynamic Provider Switching**: Switch between providers without restarting the script
- **API Key Validation**: Automatically checks if the required API key is set before switching
- **Visual Provider Indicator**: The prompt now shows the current provider in brackets (e.g., `[KIMI]>`, `[DOUBAO]>`)
- **Configuration Status**: The `status` command shows complete configuration including API key availability

### Example Usage:

```bash
# Start interactive mode
python main.py --mode interactive

# In interactive mode:
[DOUBAO]> providers        # List all providers
[DOUBAO]> provider kimi    # Switch to Kimi
[KIMI]> status             # Check current configuration
[KIMI]> help               # Show all commands
```

### Files Updated:

1. **`main.py`** - Added provider switching logic, status command, and help command
2. **`README.md`** - Documented new interactive mode commands with a comprehensive table
3. **`test_provider_switching.py`** - Created test script to verify provider switching works correctly

The implementation ensures that:
- Users can seamlessly switch between providers during a session
- API keys are properly validated before switching
- The current provider is always visible in the prompt
- All provider-specific configurations are properly updated when switching

This enhancement significantly improves the user experience by allowing dynamic provider selection without needing to restart the application or pass command-line arguments repeatedly.

1. Do NOT put the messages in tool call history. The system prompt should be left unchanged.
2. The history messages should be there even when the agent stops. When the user inputs another prompt in the console, it should continue with the original conversation history and append the new user prompt

---

### 🤖 Cursor Assistant

You're absolutely right! The conversation history should persist throughout the interactive session, and the system prompt should remain unchanged. Let me fix these issues.

---

### 🤖 Cursor Assistant

## ✅ Conversation History Persistence Successfully Implemented!

I've fixed the two critical issues you identified:

### 1. **System Prompt Remains Unchanged**
- The system prompt is now initialized once and never modified
- Tool call history and context are maintained through the conversation messages themselves, not by modifying the system prompt
- Removed the code that was updating the system prompt with context

### 2. **Conversation History Persists Across Tasks**
- Added `conversation_history` property to the agent that maintains all messages
- Each `execute_task` call now appends to the existing conversation history
- Users can have multi-turn conversations where the agent remembers previous context
- The `reset` command properly clears history and reinitializes with just the system prompt

### Key Changes Made:

#### **Agent (`agent.py`)**:
- Added `conversation_history` list to maintain persistent message history
- Created `_init_system_prompt()` method to initialize conversation with system message
- Modified `execute_task()` to append to existing history instead of creating new messages
- All messages (assistant, tool, user) are now added to both local execution and persistent history
- Added `process()` method for compatibility with test scripts
- Updated `reset()` to clear both trajectory and conversation history

#### **Interactive Mode (`main.py`)**:
- Updated status command to show conversation history message count
- Updated reset message to clarify it resets conversation history too

#### **Documentation (`README.md`)**:
- Added conversation history to key features
- Created new section explaining conversation history functionality with examples

#### **Test Scripts**:
- Created `test_conversation_history.py` to verify history persistence
- Created `demo_conversation.py` to demonstrate multi-turn conversations

### How It Works Now:

1. **Initial State**: Agent starts with only a system prompt in conversation history
2. **Task Execution**: Each user query and agent response is appended to the history
3. **Context Preservation**: Previous queries, answers, and tool calls remain in history
4. **Multi-turn Conversations**: Agent can reference information from earlier in the conversation
5. **Reset Functionality**: Clears all history except the system prompt

### Example Usage:

```python
agent = ContextAwareAgent(api_key, provider="kimi")

# First query - agent remembers this
agent.execute_task("My budget is $10,000")

# Second query - agent uses previous context
agent.execute_task("What's 15% of my budget?")

# Third query - agent recalls earlier information
agent.execute_task("Convert that to EUR")

# Reset to start fresh
agent.reset()
```

The implementation ensures that the conversation flows naturally with the agent maintaining context across multiple interactions, just like a real conversation, while keeping the system prompt pristine and unchanged throughout the session.

Why do we need to create a copy here


        # Create a copy of messages for this task execution
        messages = self.conversation_history.copy()

---

### 🤖 Cursor Assistant

You're absolutely right to question this! The current implementation with the copy is actually redundant and doesn't provide the intended benefit. Let me explain why and fix it.

## Current Issue:

The code creates a copy (`messages = self.conversation_history.copy()`) but then updates **both** `messages` AND `self.conversation_history` throughout the execution. This defeats the purpose of having a copy.

## Why This is Problematic:

1. **No rollback capability**: If an error occurs mid-execution, the conversation history is already modified
2. **Redundant updates**: We're updating two lists with the same content
3. **Potential sync issues**: Risk of the two lists getting out of sync

## Better Approach:

We should either:
- **Option A**: Use `self.conversation_history` directly (simpler)
- **Option B**: Use a copy and only update `self.conversation_history` at the end (safer)

Let me implement **Option A** (simpler and more straightforward):

---

### 🤖 Cursor Assistant

Perfect question! You identified an unnecessary redundancy in the code. 

## The Issue:

The code was creating a copy but then updating **both** the copy and the original throughout execution, which completely defeated the purpose of having a copy.

## The Fix:

I've removed the `.copy()` and now `messages` is simply a reference to `self.conversation_history`:

```python
# Before (redundant):
messages = self.conversation_history.copy()
# Then updating both messages AND self.conversation_history

# After (clean):
messages = self.conversation_history  
# Now messages IS conversation_history, so updates are direct
```

## Why This is Better:

1. **Simpler**: No redundant dual updates
2. **Clearer Intent**: The conversation history is directly modified as the conversation progresses
3. **More Efficient**: No unnecessary list copying
4. **No Sync Issues**: Can't have the two lists get out of sync

## How It Works Now:

- `messages` is just an alias/reference to `self.conversation_history`
- Any `messages.append()` directly updates the conversation history
- The history grows naturally as the conversation progresses
- No need to maintain two separate lists

## Alternative Approach (if rollback was needed):

If we actually wanted rollback capability on errors, we would do:
```python
# Create a working copy
messages = self.conversation_history.copy()
# Work with the copy during execution
# Only update the original at the END if successful
if success:
    self.conversation_history = messages
```

But for a conversational agent, the current direct approach makes more sense - the conversation history should reflect what actually happened, including any partial progress before an error.

The code is now cleaner and more straightforward!
