[Bug] `~/.claude/debug` grows unbounded with no automatic cleanup

Description

The ~/.claude/debug directory accumulates one large .txt debug log file per session with no automatic cleanup or retention policy. Over time this can consume massive amounts of disk space.

Steps to Reproduce

1. Use Claude Code regularly over several weeks
2. Check du -sh ~/.claude/debug/

Impact

• 44,635 files accumulated over ~4 weeks
• 179 GB of disk space consumed
• Average ~4 MB per session log

Expected Behavior

Claude Code should either:

• Automatically delete debug logs older than N days, or
• Cap the total size/ file count of the debug folder, or
• Provide a setting to disable/limit debug logging

Workaround

Manually delete the folder and set up a cron job:

0 3 * * * find ~/.claude/debug -name '*.txt' -mtime +7 -delete

Environment

• macOS Tahoe 26.3.0
• Claude Code (claude-sonnet-4-6)
