In week2 system-hint, we should print the full messages list of the last LLM call to the trajectory.json file. In addition, do not use mock time. Use real system time.

### 🤖 Cursor Assistant

I'll help you modify the week2 system-hint project to print the full messages list of the last LLM call to the trajectory.json file and use real system time. Let me first explore the project structure.

---

### 🤖 Cursor Assistant

Let me check the current trajectory.json to understand the format:

---

### 🤖 Cursor Assistant

Now I understand the structure. I need to modify the `agent.py` file to:
1. Capture the full messages list sent to the LLM in the last call
2. Save it to the trajectory.json file
3. Ensure real system time is used (not mock time)

Let me make these changes:

---

### 🤖 Cursor Assistant

Now let me update the `_save_trajectory` method to include the last LLM messages:

---

### 🤖 Cursor Assistant

Now let me update the `execute_task` method to store the messages sent to the LLM:

---

### 🤖 Cursor Assistant

Now let me update the `reset` method to include resetting the last_llm_messages:

---

### 🤖 Cursor Assistant

Now let me check for any linter errors in the modified file:

---

### 🤖 Cursor Assistant

Perfect! No linter errors. Let me verify the changes by checking the configuration and creating a simple test:

---

### 🤖 Cursor Assistant

Let me create a simple test to verify the trajectory saving with the last LLM messages:

---

### 🤖 Cursor Assistant

Now let me run the test to verify our changes work correctly:

---

### 🤖 Cursor Assistant

Perfect! The tests pass. Now let me verify with a quick real example to see the trajectory output:

---

### 🤖 Cursor Assistant

Excellent! The changes are working perfectly. Let me clean up the test files and create a summary:

---

### 🤖 Cursor Assistant

Perfect! Let me create a summary of the changes:

---

### 🤖 Cursor Assistant

Perfect! Let me now run the existing tests to make sure nothing broke:

---

### 🤖 Cursor Assistant

Excellent! All tests pass. Here's a summary of the changes made:

## Summary of Changes

I've successfully modified the week2 system-hint project to meet your requirements:

### 1. **Full LLM Messages in Trajectory** ✅
Added a new field `last_llm_messages` to the trajectory.json file that captures the complete messages list sent to the LLM in the last call, including:
- All conversation history
- Dynamic system hints (system state, TODO list, timestamps, etc.)

**Changes made to `agent.py`:**
- Line 120: Added `self.last_llm_messages = None` to track last LLM messages
- Line 210: Added `"last_llm_messages": self.last_llm_messages` to trajectory output
- Line 813: Store messages before sending to LLM: `self.last_llm_messages = messages_to_send`
- Line 971: Reset in the `reset()` method

### 2. **Real System Time (No Mock Time)** ✅
Verified and ensured real system time is used throughout:
- Default configuration has `simulate_time_delay = False` (line 68)
- All timestamps use `datetime.now()` which reflects actual system time
- The mock time feature is only used when explicitly enabled for demos

### Key Benefits:
1. **Complete debugging context**: You can now see exactly what the LLM received, including dynamic system hints
2. **Accurate timestamps**: All times reflect real system time for accurate analysis
3. **Better trajectory analysis**: Distinguish between permanent conversation history and the complete LLM input

### Example Trajectory Output:
```json
{
  "timestamp": "2025-09-30T20:26:32.057323",
  "conversation_history": [/* 3 messages */],
  "last_llm_messages": [/* 4 messages - includes system hint */],
  "config": {
    "simulate_time_delay": false
  }
}
```

All changes have been tested and verified with no linter errors. The existing tests continue to pass, ensuring backward compatibility.
