What's Wrong?

Claude keeps running into issues with quotes when dealing with Folder names with spaces in them. This error is new, never was a problem before.

What Should Happen?

I should be able to have file folder names with spaces without throwing an error.

Error Messages/Logs

● Bash(cat > /tmp/write_calc100.py << 'ENDPY'
      script = r'''"""Calculate.…)
  ⎿  Error: Exit code 2
     /usr/bin/bash: -c: line 2: unexpected EOF while looking for matching `''

     /usr/bin/bash: -c: line 2: unexpected EOF while looking for matching `''

● The heredoc keeps failing with the escaping. Let me write it as a Python file directly:

Different project

● Write(docs\USER_MANUAL.md)
  ⎿  Error: EEXIST: file already exists, mkdir 'C:\Users\tritl\OneDrive\Nate\The Balance of Power\docs'

● Bash(cd "C:\Users..." && python -c "
      import pathlib…)
  ⎿  Error: Exit code 2
     /usr/bin/bash: -c: line 129: unexpected EOF while looking for matching `''

     /usr/bin/bash: -c: line 129: unexpected EOF while looking for matching `''

● The single quotes in the content are breaking the heredoc. Let me use a Python script file instead.

● Bash(cd "C:\Users..." && python -c "
      import pathlib, textwrap…)
  ⎿  Error: Exit code 2
     /usr/bin/bash: -c: line 4: unexpected EOF while looking for matching `''

     /usr/bin/bash: -c: line 4: unexpected EOF while looking for matching `''

● The Python inline string has quotes conflicting. Let me use a script file approach.

● Bash(cd "C:\Users..." && python -c "
      import pathlib, sys…)
  ⎿  Written 0 chars

● Let me use a different approach — write a temp Python script.

● Bash(cd "C:\Users\..." && cat > /tmp/write_manual.py << 'PYEOF'
      import pathlib…)
  ⎿  Error: Exit code 2
     /usr/bin/bash: -c: line 116: unexpected EOF while looking for matching `''

     /usr/bin/bash: -c: line 116: unexpected EOF while looking for matching `''

● The apostrophe in "..." is breaking the heredoc. Let me use a different delimiter.

Steps to Reproduce

Try writing to a file located inside of a folder with a space in the folder name.
