Claude Code creates /tmp/claude-*-cwd files for directory tracking but never cleans them up. Over time, hundreds of files accumulate, consuming disk space and inodes.
800+ temp files consuming 1.2GB (#8856)
A user ran ls /tmp/claude-* | wc -l and found 823 files. Each Claude Code session creates new files without deleting old ones. Over weeks, this fills the /tmp partition.

Disk full → .claude.json corruption
When /tmp fills up, Claude Code's config file (~/.claude.json) can become zero-length on the next write. This destroys all authentication tokens and project settings, requiring manual recovery.
# How many temp files do you have right now?
ls /tmp/claude-* 2>/dev/null | wc -l
# How much space?
du -sh /tmp/claude-* 2>/dev/null | tail -1Install the temp-file-cleanup Stop hook:
npx cc-safe-setup --install-example temp-file-cleanupThis runs automatically when Claude Code exits, deleting temp files older than 1 hour (keeping files from concurrent sessions).
# Delete all Claude temp files
find /tmp -maxdepth 1 -name "claude-*" -type f -delete
# Delete only old ones (safe for concurrent sessions)
find /tmp -maxdepth 1 -name "claude-*" -type f -mmin +60 -deleteFull safety setup in 10 seconds
