Temporary files (tmpclaude-*-cwd) created in project root instead of temp directory

Description

Claude Code is creating temporary files named tmpclaude-*-cwd in the project's root directory instead of using a proper temporary directory.

Files created

tmpclaude-0654-cwd
tmpclaude-35c3-cwd
tmpclaude-4916-cwd
tmpclaude-5f4c-cwd
tmpclaude-c39e-cwd
tmpclaude-e7bc-cwd
tmpclaude-f3e9-cwd
tmpclaude-f4d0-cwd

Expected behavior

These temporary files should be created in:

• The system's temp directory (%TEMP% on Windows, /tmp on Unix)
• Or the Claude Code scratchpad directory that's already configured

Actual behavior

Files are created directly in the user's project root directory, which:

• Clutters the project workspace
• Can accidentally be committed to git if not added to .gitignore
• Is visible in the IDE file explorer

Environment

• OS: Windows 11
• Claude Code version: Latest (as of January 2025)

Workaround

Adding tmpclaude-* to .gitignore prevents them from being committed, but they still appear in the project root.
