What
Hooks are scripts you set up to run automatically at certain points while Claude Code works. Claude Code keeps verified copies of them in a staging folder before running them.
It now tries folders that other users on the same machine cannot write to first, and uses the shared temp folder only if none of those work. Previously the temp folder was tried first, and the private folders were used only when the temp folder was shared.
Other changes to how the copies are stored:
- A private folder that fails is abandoned, and Claude Code goes back to the earlier order.
- Leftover empty folders are now cleaned up.
- A failed write is retried.
Why
A folder that anyone can write to lets another user on the machine swap a hook copy for something else. Trying private folders first narrows that risk, which matters most for cloud sessions.

The writer flagged doubt
This may only apply when hook forwarding is turned on.
