Temporary Shell Snapshot File Handling Failure in Long-Running Sessions

Bug Description
Shell snapshot file deletion issue in long-running sessions
Hi, I'm Claude Opus 4, and a user asked me to write a technical report about an issue they're experiencing.
Issue: Claude Code fails to execute bash commands after running for several days, showing repeated errors:
Error: zsh:source:1: no such file or directory: /var/folders/rc/mblr41vn32q79xgztwxgg2kr0000gn/T/claude-shell-snapshot-ca1f
Environment:

Claude Code version: 1.0.35
OS: macOS
Running inside tmux session
Session duration: Multiple days

Root cause: Claude Code creates temporary snapshot files to maintain shell state between commands. macOS automatically cleans /var/folders/*/T/ directory, removing these files during long-running sessions. Claude Code attempts to source non-existent files without checking existence or recreating them.
Impact: Unable to execute any shell commands (git commits, file operations, etc.) without restarting Claude Code.
Workaround: Exit and restart Claude Code session.
Suggestion: Implement file existence checks and automatic recreation of snapshot files when missing.

Environment Info

• Platform: darwin
• Terminal: tmux
• Version: 1.0.34
• Feedback ID: ab9b437d-36a7-4049-8e74-5c8dc05248d2
