stop_hook.py crashes with PermissionError when cwd is not readable

Bug

stop_hook.py crashes when the current working directory is not readable (e.g., macOS sandbox restrictions on Claude Code).

Error

Traceback (most recent call last):
  File "stop_hook.py", line 45, in <module>
    main()
  File "stop_hook.py", line 35, in main
    cwd = os.environ.get('FEWWORD_CWD', os.getcwd())
PermissionError: [Errno 1] Operation not permitted
/bin/sh: python: command not found

Root cause

Two issues:

1. os.getcwd() in stop_hook.py:35 — when FEWWORD_CWD is not set, os.getcwd() is used as fallback. This raises PermissionError if the working directory is not readable (common with macOS sandbox).

2. || operator in hooks.json — the hook command pattern is:

   command -v python3 >/dev/null && python3 "...stop_hook.py" || python "...stop_hook.py"
   

   When python3 is found but the script itself fails (non-zero exit), the || triggers and tries to run python, which doesn't exist on macOS. This produces the secondary error /bin/sh: python: command not found.

Suggested fix

stop_hook.py:35 — wrap os.getcwd() in try/except:

try:
    cwd = os.environ.get('FEWWORD_CWD') or os.getcwd()
except (PermissionError, OSError):
    cwd = os.path.expanduser('~')  # safe fallback

hooks.json — use subshell grouping so || only fires when python3 is not found, not when the script fails:

(command -v python3 >/dev/null && python3 "...") || python "..."

Or simply:

python3 "..." 2>/dev/null || python "..."

Environment

• macOS (Darwin 25.2.0)
• Claude Code CLI with sandbox
• FewWord 1.3.10
• python3 available, python not available
