What's Wrong?

Plugin marketplace auto-updates reset file permissions on all .sh files to 644 (no execute bit).

This causes hook scripts to fail with "Permission denied" errors. The fix doesn't persist — permissions are lost again on each update.

What Should Happen?

Shell scripts distributed via the plugin marketplace should retain execute permissions after auto-updates. Either the git repo should track the execute bit, or the update process should chmod +x .sh files after syncing.

1. Install any plugin with .sh hook scripts (e.g., ralph-loop)

4. Any hook that references a .sh file fails with "Permission denied"

Workaround: find ~/.claude/plugins/marketplaces/claude-plugins-official -name "*.sh" -exec chmod +x {} +
