Shell Snapshot Path Parsing Fails for Usernames with Spaces

Bug Description
Claude Code v1.0.48 Bug Report: Shell Snapshot System Fails with Usernames Containing Spaces

Summary

Claude Code v1.0.48 introduced a regression where the Bash tool fails completely for users with spaces in their usernames due to
improper path parsing in the new shell snapshot system.

Environment

• Claude Code Version: 1.0.48
• OS: macOS (Darwin 24.5.0)
• Shell: zsh
• Username: Contains space (e.g., John Doe)

Bug Details

Error: zsh:source:1: no such file or directory: /Users/John

Root Cause: v1.0.48 change "Moved shell snapshots from /tmp to ~/.claude for more reliable Bash tool calls" breaks path parsing
for usernames with spaces. Shell snapshot system attempts to source /Users/John instead of /Users/John Doe/.

Steps to Reproduce

1. Have macOS username with spaces (e.g., "John Doe")
2. Use Claude Code v1.0.48 Bash tool
3. Any command triggers the error

Impact

• Severity: Critical - All Bash tool functionality broken
• Affected Users: Anyone with spaces in username
• Regression: Worked fine in v1.0.45

Workaround

sudo ln -s "/Users/John Doe" /Users/John

Expected Fix

Shell snapshot system should properly quote/escape paths containing spaces when generating snapshot files.
