[Solved ✅] FILETOOL_OPEN_FILE moves cwd to parent before opening file resulting in error

# Agent: Planner
## Thought: Thought: The previous attempt failed because I tried to combine the action and the final answer.  I need to find the relevant files, understand their structure, and then give specific instructions to the Code Editor.
## Using tool: FILETOOL_FIND_FILE
## Tool Input: 
"{\"pattern\": \"src/flask/blueprints.py\", \"include\": [\"/home/kostis/repos/flask\"], \"exclude\": []}"
## Tool Output: 
{'data': {'error': '', 'current_working_directory': '/home/kostis/repos/flask', 'results': ['src/flask/blueprints.py'], 'message': ''}, 'error': None, 'successful': True}


# Agent: Planner
## Thought: Thought: Now that I've found the file, I need to open it and analyze the code to identify the specific functions that handle blueprint registration and validation.  I'll look for places where blueprint names are constructed or checked.
## Using tool: FILETOOL_OPEN_FILE
## Tool Input: 
"{\"file_path\": \"src/flask/blueprints.py\"}"
## Tool Output: 
{'data': None, 'error': 'File not found: File /home/kostis/repos/src/flask/blueprints.py does not exist!', 'successful': False}
