What
Claude Code periodically cleans up the ~/.claude/shares folder. It used to remove only files ending in .zip. It now also removes temporary files whose names contain .zip.tmp.. Before removing one, it runs an extra check on the file.
Why
If exporting a share is interrupted, it can leave a half-written temporary file behind. Those leftovers are now cleaned up instead of piling up on disk.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
What the extra check tests before a temporary file is removed is not known; it may check that the process that created the file has ended.
