Plan a Code Change Before Writing Any Code

Your supervisor asks you to add error handling to load_data.py — right now, it crashes with an unhelpful traceback if a CSV file is missing or malformed. This touches at least two functions across the script, so you want a clear plan before touching anything.

Plan mode reads your project with read-only tools and returns a numbered implementation plan for you to review. No files are changed until you explicitly approve.

The team's project is already in your working directory at /home/repl/climate-analysis/.
