First, let me understand what the user is asking for:
1. They want to see the complete thinking process
2. They mentioned that thinking was being truncated before
3. They want full display of reasoning

Now I should check what tools are available and plan my approach:
- I can use file operations to read/write
- I can use system commands if needed
- I should break this down into steps

My plan:
1. First, acknowledge their request
2. Explain what I've implemented
3. Show them how the thinking process now works
4. Provide examples of the new functionality"""
