[BUG] Claude loses access to Bash() tool

Environment

• Platform (select one):
• [X] Other: Claude Code 1.0.17
• Operating System: macOS 15.4.1
• Terminal: iTerm2

Bug Description

Claude loses the ability to run Bash() tool. No obvious cause although it does seem to happen first thing in the morning when a CC instance is left open (but not actively executing commands) overnight. This has happened 2 or 3 times in the past month. The 'claude-shell-snapshot' directory is mentioned here, but the context seems different than this case. Although notably I'm also using zsh, which was noted in the comments as a possible influencing factor.

Bash(echo "Testing shell")
     Error: zsh:source:1: no such file or directory: 
     /var/folders/sd/s2s25sbn0j51fb1bfqhp17540000gp/T/claude-shell-snapshot-9e0b

^^After it hits this once, every attempt to Bash() has the same issue.
