Temporary tmpclaude-*-cwd files accumulate in working directory

Description

Claude Code creates temporary files named tmpclaude-XXXX-cwd in the current working directory to track the working directory of bash sessions. These files accumulate over time and are not cleaned up when sessions end.

Problem

1. Files created in wrong location: These temp files are created in the user's working directory instead of a proper temp folder (like $TMPDIR, /tmp, or %TEMP%)
2. No automatic cleanup: The files persist after sessions end, leading to accumulation
3. Pollutes project directories: Users end up with dozens of these files in their project folders

Example

After a few hours of use:

$ ls tmpclaude-*-cwd | wc -l
39

Each file contains only the working directory path:

$ cat tmpclaude-00e2-cwd
/c/Users/theod/Documents/DATA/QtProjects

Expected behavior

1. These temporary files should be created in the system's temp directory
2. They should be automatically cleaned up when a bash session ends
3. Alternatively, use a different mechanism that doesn't require creating files in the working directory

Environment

• OS: Windows 11
• Shell: Git Bash (default in Claude Code on Windows)
• Claude Code version: Latest (January 2025)
