Description

Plugin hook scripts (shell scripts) lose their execute permission when cached via the unknown version path, causing Permission denied errors at runtime.

Steps to reproduce

Have a plugin with a hook script (e.g., ralph-loop with stop-hook.sh)
Wait for the plugin cache to sync — the unknown version path writes the file without the executable bit
When the marketplace directory syncs from this cache, the hook script is no longer executable
Hook invocation fails with: /bin/sh: .../stop-hook.sh: Permission denied

Evidence

Three cache versions of the same file show the issue:

# Versioned caches — correct (+x)
-rwxr-xr-x  stop-hook.sh   (cache/.../d53f6ca4cdb0/hooks/)
-rwxr-xr-x  stop-hook.sh   (cache/.../b10b583de281/hooks/)

# 'unknown' cache — missing +x
-rw-r--r--  stop-hook.sh   (cache/.../unknown/hooks/)

The marketplace copy inherits the broken permissions from the unknown cache:

-rw-r--r--  .../marketplaces/claude-plugins-official/plugins/ralph-loop/hooks/stop-hook.sh

Workaround

chmod +x ~/.claude/plugins/marketplaces/claude-plugins-official/plugins/ralph-loop/hooks/stop-hook.sh

Recurs on next plugin update that goes through the unknown path.

Expected behavior

The plugin cache should preserve file permissions (specifically the executable bit) when writing to the unknown version path, matching the behavior of the versioned cache paths.

Auto-fix with Notification start hook:

find ~/.claude/plugins -name '*.sh' ! -perm /111 -exec chmod +x {} \; 2>/dev/null
exit 0

This was fixed in v2.1.86 — Plugin hook scripts now retain their execute permission across all plugin cache and extraction paths. If you're still seeing this in the latest version, please comment with your version and repro and we'll reopen.
