mem-sync — Cross-Device Memory Sync

Synchronizes <repo>/.memories/ across machines through a dedicated, isolated per-user branch memories/<email-localpart> using a background git worktree, so the active development branch and your editor workspace are never disturbed.

Per-User Branch

The sync branch is derived from git config user.email: the part before @, lowercased and slugified (non-alphanumeric runs become -). User@Example.com → memories/user. Each user pushes/pulls only their own branch, so two developers on the same repo never collide on same-date log filenames.

Windows

On Windows, run this skill's script through Git Bash (Git for Windows). A PATH guard at the top of the script prepends the MSYS usr/bin so find/tar are not shadowed by the native same-name tools; if a required POSIX tool is still missing, the script aborts with an explicit error naming the missing tool.
