Bash tool produces permission denied errors in stderr for temp working directory

Description

The Bash tool consistently outputs permission denied errors to stderr, even though the commands execute successfully:

zsh:1: permission denied: /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/claude-XXXX-cwd

Steps to Reproduce

1. Use the Bash tool with any command that requires a working directory
2. Observe stderr output contains permission denied errors
3. The command still executes successfully, but the error messages clutter the output

Expected Behavior

The Bash tool should handle temporary working directories without producing permission denied errors in stderr.

Actual Behavior

Every Bash command execution includes a permission denied error for a temporary directory path, making output difficult to read.

Environment

• OS: macOS (Darwin 24.6.0)
• Shell: zsh
• Claude Code version: Latest

Impact

The error messages don't affect functionality but create significant noise in the output, making it harder to read actual command results.

Suggested Fix

Handle temp directory creation/access more cleanly to avoid permission errors, or suppress these specific stderr messages since they don't indicate actual failures.
